#UnboxingDay – Ukraine War at Sea with Harpoon V from The Admiralty Trilogy Group) — via @ADragoons

RockyMountainNavy, 19 May 2022 For us navalist Grognards, the war in the Ukraine has been feast or famine. Well, mostly famine. Aside from the sinking of the Russian Federation Navy ship Moskva, the war at sea has been light on action. Fortunately, as a wargamer you can look at alternate happenings, and what better way…

#UnboxingDay – Ukraine War at Sea with Harpoon V from The Admiralty Trilogy Group) — Armchair Dragoons

#MaritimeMonday – Russia vs. Ukraine in Harpoon V #Wargame

This weekend I added to my digital Harpoon V (Admiralty Trilogy Group) wargame collection by purchasing Russia’ s Aircraft: Soviet & Russian Military Aircraft 1955-2020. At the same time I bought the latest issue of The Naval SITREP (#62, April 2022) which has a featured article, “Ships and Aircraft of the Ukrainian Navy and Air Force.” Now I can rerun my Moskva sinking scenario with the benefit of several plays (aka “rules learning sessions”) and validated game data.

While I have already studied the sinking of the Moskva using Harpoon V, the only other real naval engagement has been a Ukrainian Bayraktar TB2 UAV versus a Russian Raptor patrol boat (PB).

Like the video shows, in Harpoon V this battle is very quick to finish. The Harpoon V rules note:

Small craft, size class F and G, are tougher, ton for ton, and cannot be sunk by successive turns of fire that add up to their total damage point rating. They have to roll for critical hits for damage effects, but their point total is not reduced after each hit like larger craft. If the damage they receive in a single turn is twice their damage point rating, they are sunk.

14.1 Applying Damage

So…a Bayraktar TB2 dropping a single GAM-L hits and scores 14 damage points. The Raptor PB has a damage rating of…6.2.

Ooops.

One less Raptor…

Look for the full “unboxing” video of Russia’s Aircraft, The Naval SITREP #62, and Russia’s Navy at the Armchair Dragoons on Thursday, May 19.

#Wargame Wednesday – Did Poseidon feed Moskva to Neptune, or was it Mineral-U spirits? What does Harpoon 5 (admiraltytrilogy.com) wargame say?

There are reports floating around the internet making the interesting claim that a U.S. Navy P-8 Poseidon maritime patrol aircraft was operating in the area the night the RFN Moskva was sunk. The implication is that the U.S. Navy P-8 fed targeting data to the Ukrainian Navy Neptune coastal defense anti-ship missile battery and therefore contributed to the sinking of the cruiser.

On April 13th, a P-8 Poseidon with a hex code of AE681B was spotted leaving the U.S. Airbase at Sigonella in Sicily, Italy, and was then detected over the Mediterranean at 1:32 pm local Kyiv time.

FlightRadar24 data then showed the P-8 flying over the Balkans and Bulgaria, after which it flew over the Romanian coast in the Black Sea in the afternoon. The last known position of the aircraft was Valea Nucarilor, Romania which is about 12 miles from the Ukrainian border, at 3:27 pm, about 100 miles from the location where the Moskva was found after allegedly being hit.

It had begun descending from an altitude of around 29,000 feet down to 11,900 feet just before dropping off FlightRadar24 tracking and disappearing.

It disappeared for about 2 hours and 56 minutes before appearing again at 6:23 pm, where it was seen flying towards the Black Sea coast above Casimcea in Romania, around 37 miles from the position it had been before it disappeared.

It is standard procedure for an aircraft to turn off its transponder or the device that broadcasts its location before entering any kind of conflict zone.

Around 19 minutes later the aircraft disappeared from the radar once again and then reappeared after 42 minutes near Abrud, in Romania at 7:24 pm. After that, it traveled back to Sigonella.

The Moskva was first reported to have been hit at 8:42 pm after a Facebook post that came from a Ukrainian who had links to the military, and then at 10:31 pm, the Ukrainian governor of Odesa confirmed that a strike had been carried out on the vessel.

oslint.org, April 21,2022

Using the wargame Harpoon 5 (Admiralty Trilogy Group, 2021) lets see what we can learn. For this exploration we will need to dig deep into two particular rules sections; 5.0 Detection and 6.0 Fire Control.

In Harpoon 5, detection takes place in the Detection Phase of the Tactical Turn Sequence (2.3.3). Assuming the P-8 was using it’s surface search radar in the active mode after descending to 11,900 ft (3,627 m or Medium Altitude), taking the Radar Line of Sight table (part of rule 5.2.8 Radar Line of Sight) we cross-reference a P-8 flying at Medium Altitude and a Medium-size surface target to get a detection range of 170 nm; Moskva was very likely detected by the P-8 (and Moskva very likely also detected the P-8 in return).

The implication in the story is that the P-8 passed targeting data. In Harpoon 5, data is passed during the Detection Phase when players, “exchange visual, radar, sonar, Electronic Support (ES), data links, and other sensor information.” Once Moskva was detected, the P-8 would have to pass a fire control solution (see 6.3 Fire Control Solutions) to the Neptune battery to enable an attack. Per rule 6.3.1 Fire Control Solution Quality, there are four levels of quality; Good, Fair, Poor, and No Attack. Building a fire control solution is a combination of time (longer time in contact the better), contact speed, the generation (age) of the Combat System (aircraft are always a modifier of 0), and the generation of the weapon being used in the strike. Equally important is the Tactical Data Link being used to “pass” the solution. Given the amount of time the P-8 allegedly spent near Moskva—hours—the quality of the fire control solution would very likely be the best possible—Good.

In Harpoon 5, like in real life, how does the P-8 get that Good fire control solution to the Neptune battery? Did it use a Real Time or Near Real Time tactical data link? Although there are plenty of reports the U.S. is sharing intelligence with Ukraine*, there is no clear evidence that tactical data links are being used. A more plausible scenario is that U.S. and NATO intelligence is being collated and passed to Kyiv. At best, and assuming the P-8 was directly in contact with Ukrainian forces (a big assumption), we have to go to rule 6.3.10 Sharing Contact Information Without TDLs which states:

Contact data can be manually shared by radio (voice or teletype) or even cell phones, however, the process is slow, with a higher risk of errors, and has little tactical use other than reporting the presence of a contact in the area.

6.3.10

Even if the fire control solution was passed in real (or near) time to the Ukrainians, it was good at ~6:23 pm when the P-8 reappeared in the flight tracking application. This was maybe as long as two hours before Moskva was struck. There is no way in Harpoon 5 to keep a “good” fire control solution when not in contact. After two hours, the fire control solution from the P-8 by-the-rules was of No Attack quality.

If the Ukrainian Neptune battery commander in Harpoon 5 had only the general information (“No Attack” quality fire control solution) provided by the P-8, the commander is forced to use a Bearing Only Launch (BOL) following rule 6.3.6 of the same name. BOL attacks in turn are executed using rule 8.4.2 Bearing Only Launch (BOL) Attacks. The commander must pick a launch azimuth and a range for the seeker head to activate and start looking. The fire control solution quality is automatically Poor (interestingly, an improvement over the No Attack starting condition). As in any surface missile attack, when the seeker head opens the player must make a Placement Roll (6.3.8 Rolling for Weapon Placement) to see if the seeker finds its intended target. The chances of an anti-ship cruise missile using a BOL and finding its intended target when the seeker activates is 30%.

How could the Neptune battery commander improve his odds using the rules in Harpoon 5? It’s quite possible he used his organic sensors. The Neptune ASCM is part of a weapons complex that includes the missile, the launcher, command and control, and sensors. The sensor intended for the Neptune system is called Mineral-U. The Mineral-U is an interesting system, known in Harpoon 5 as a Targeting Radar (SS-T):

Targeting radars (SS-T) are a type of surface-search radar used by the Soviet Union/Russia. They not only function as a surface search radar optimized to use the surface duct to extend their range over the horizon, but can serve as extremely precise ES [Electronic Support] sensors….They can use the radar duct to extend their range.

5.2.4 Shipboard Radar Types

Although one could argue about the lack of Russian air superiority, the Neptune battery commander might not want to “go active” and try to get an Active RF [Radio Frequency] fire control solution. To radiate the Mineral-U radar is to invite an attack. Alternatively, it is possible to work towards a Passive RF fire control solution using rule 6.3.2 Radio-Frequency (RF) Fire Control Solution. To achieve a Good solution for the Neptune means tracking Moskva for at least 15 minutes (5 Tactical Turns); a risk but one well worth it? With a Good quality fire control solution the Placement Roll is 90%—a vast improvement over the 30% chance with a BOL Poor quality solution.

This little exploration using Harpoon 5 shows us that, while it is technically possible the P-8 “tracked” Moskva, even if that data was somehow passed to the Ukrainians it was more likely used for (at best) general situational awareness and not for targeting. To achieve the greatest chance for success, the Ukrainian Neptune battery commander more likely used organic sensors to Find, Fix, Track, and Target Moskva to enable the Neptune missiles to Engage. Harpoon 5 gives us a tool to Assess strike success.


* UPDATE: On Tuesday, April 26, NBC News published a story that talked about the degree of intelligence sharing between the United States and Ukraine:

Ukrainian forces have used specific coordinates shared by the U.S. to direct fire on Russian positions and aircraft, current and former officials tell NBC News.

As Russia launched its invasion, the U.S. gave Ukrainian forces detailed intelligence about exactly when and where Russian missiles and bombs were intended to strike, prompting Ukraine to move air defenses and aircraft out of harm’s way, current and former U.S. officials told NBC News.

That near real-time intelligence-sharing also paved the way for Ukraine to shoot down a Russian transport plane carrying hundreds of troops in the early days of the war, the officials say, helping repel a Russian assault on a key airport near Kyiv.

“There has been a lot of real-time intelligence shared in terms of things that could be used for specific targeting of Russian forces,” said a former senior intelligence official familiar with the situation. The information includes commercial satellite images “but also a lot of other intelligence about, for example, where certain types of Russian units are active.”

Ukrainian forces have used specific coordinates shared by the U.S. to direct fire on Russian positions and aircraft, current and former officials tell NBC News.

While the phrase “real-time intelligence” is liberally sprinkled throughout the article, and some of the reporting implies extremely timely exchange of intelligence, the association of the P-8 and the Moskva sinking is not discussed. The fact remains that even if the P-8 passed target-quality intelligence “in real-time,” the data was “aged” by at least two hours before any Neptune strike. The Harpoon 5 -derived situation still stands as a very plausible explanation of the likely events at the time of the sinking.

Moskva Burning – Using the #wargame Harpoon V from admiraltytrilogy.com to assess the story

Update as of April 14, 4:30pm Eastern time. Reports from Russian state media now say Moskva sunk while under tow.

As I start writing this post, it is the day after the news broke that the Russian Navy cruiser Moskva either was struck by Ukrainian coastal anti-ship missiles or suffered an ammunition explosion and fire. Pending further developments, let’s assume for the purposes of this post that the ship was attacked. This allows me to look at the event through the lens of wargaming, specifically using the rules for Harpoon V: Modern Tactical Naval Combat 1955-2020 (designers Larry Bond & Chris Carlson, Admiralty Trilogy Group, 2021).

Courtesy ATG

In the October 2006 issue (#31) of The Naval SITREP: The Journal of the Admiralty Trilogy Game System, the co-designers of Harpoon V assessed the anti-ship cruise missile (ASCM) attack on the INS Hanit in July 2006. I’m not going to go into the same technical depth here but instead want to talk a bit about what Harpoon V helps explain and what it doesn’t.

Given that Moskva is a major combatant with a wide assortment of radars and defensive systems, the result of the attack/accident seems almost implausible. On paper this is a Ukrainian David vs. a Russian Goliath. Alternatively, how could the Russian Navy lose a ship to a fire? A closer examination of a plausible “engagement” using the Harpoon V rules reveals it’s not as lopsided as one might think.

Combatants

If reports are to be believed, Moskva was struck by by two RK-360MC Neptun (Neptune) anti-ship cruise missiles. Neptune is generally reported to be a Ukrainian version of the Russian Kh-35U but with a longer body, more fuel, and a larger booster. For the purposes of this discussion, let’s use the Kh-35U which is listed as the Uran (3M24) [SS-N-25 Switchblade] in Annex D1 of Russia’s Navy: Soviet & Russian Naval Vessels, 1955-2020 (Admiralty Trilogy Group, 2021). The most important data element is perhaps the damage caused by the 150kg warhead which Harpoon V rates as “35+D6/2” or 36-38 damage points. Admittedly, this number may be a bit low given the Neptune has more fuel and is larger, factors which lead to more damage in Admiralty Trilogy models.

Moskva is (was?) the lead ship of the Project 1164 Atlant class. To Cold War Grognards like me it’s perhaps better known as a Slava-class guided missile cruiser. The lead ship, Slava, entered service in 1983 and eventually was renamed Moskva in 1995. This particular ship was overhauled between 1991-2000 and was to be overhauled again in 2016. Reports indicate the overhaul stalled for lack of funds and the ship reentered service in 2019 with few—or none—of the planned upgrades completed. Full details for Moskva are found in Annex A of Russia’s Navy. Of particular concern to this analysis, Moskva is rated at 341 damage points.

The “Engagement”

There are many unanswered questions about how the Ukrainians may have hit Moskva with two ASCMs. In Harpoon V one can play out the detection, engagement, and damage results. While many pundits are saying that Moskva “should” have seen—and defeated—the inbound missiles, Harpoon V helps us understand why this may have not been an “automatic” thing.

Detection

  • Missile Size/Height of Flight: The Neptune is a “Very Small” missile that approaches at “Very Low” altitude (Annex D)
  • Radar Detection Range: The MR-710 Fregat-M (Top Steer) air search radar has a detection range of 27 nm versus a VSmall target (Annex J1)
  • “A radar’s range is reduced by rising sea states, rain, and nearby land masses” (5.2.9 Environmental Effects on Radar)
    • Although it is unclear exactly where Moskva was operating, general weather reports from the region indicate poor weather with possible precipitation; assuming Sea State 3 with Light Rain the detection range is reduced by 40%
    • The Fregat-M is a 4th Generation radar so technically it should be able to deal with the environmental clutter and keep the full detection range—if the crew was properly trained.
  • Missile Speed: The 3M24 flies at 580 knots, or almost 10 nm a minute. That’s a little less than one Tactical Turn (3 minutes, or 6x 30 second increments) in Harpoon V.

Once the missile was detected the ship’s defenses should have engaged. Maybe…but not so fast…

Of SAMs and CIWS…

  • Reaction Time: Rule 8.1.1.3 covers Reaction Time; with a 3rd Generation SAM the normal delay is 3 increments (90 seconds) with a variable 0 to +4 increments added (see Combat System Reaction Time and Combat System Reaction on page 8-4).
    • Moskva at best may have gotten one SAM volley off and then point defense CIWS—if they were fully alerted at General Quarters
  • SAMs
    • The S-300 Fort (5V55R) [SA-N-6a Grumble] has a minimum range of 2.7nm (Annex D1)
    • The Osa-MA (9M33M2 [SA-N-4a Gecko] has a range of .5 to 6.5 nm (Annex D1)
    • Using 8.1.1 Radar-Guided Surface-to-Air Missiles (SAMs), step 7) Punch the Table, we look up SAM Intercept Table – VLow Altitude Targets and cross-reference Subsonic & Transonic with 3rd Generation (Fregat-M radar) and get”S-P” meaning there will be one chance to engage at Short Range and one chance for Point Defense (good guess above!)
    • If the S-300 Fort got off a two-SAM salvo, the Probability of Kill (Pk) is around 80%; the Osa-MA is a bit less with a Pk of ~75% for a two-SAM salvo
  • CIWS
    • Moskva mounts two, twin AK-130 130mm/70 guns; given the short reaction times involved I’m going to rule they were very likely not able to get into action fast enough to engage the inbound missiles
    • Moskva also mounts six AK-630 30mm close-in-weapon systems (CIWS); assuming one pair is able to engage at Point Blank Range it has roughly a 76% chance of knocking down a missile.

The defensive model in Harpoon V assumes ships are at General Quarters with all sensors and weapons at the ready. General Quarters is also very hard to maintain with watertight doors secured and people constantly on edge. It is more likely that Moskva was operating in some lesser readiness condition. This of course means sensors and weapons may not have been ready (extending the Reaction Time) and watertight integrity/damage control teams may not have been set to immediately deal with damage.

Damage (Out of) Control

Regardless of the defenses, if stories are to believed at least two ASCM got through and hit. Let’s see how Harpoon V portrays that:

  • Applying Damage (14.1): Two hits cause ~74 points of damage which is less than the 85 needed to reach 25% damage and no loss in speed (14.1.1); 341-74=267 damage points remaining
  • Ship Critical Hits (14.1.2): To compute damage ratio take 74/267 for a result of .277 rounded down to .2; the Critical Hit Damage Ratios table indicates a a D6 roll of 4 is 1x Critical, 5 is 2x Critical, and 6 is 3x Critical.
  • Missile Impacts (14.1.5): Guided missiles cause additional Critical Hits because of the airframe and fuel based on the damage points from the missile; the 3M24 will cause D6/2 extra Critical Hits PLUS one Automatic Fire Critical hit
  • Critical Hit summary: So far that’s between 0-6 Critical Hits with an additional automatic Fire Critical
  • Fire Critical (14.4): Rolling D6 gets 3 or 3% of the original 341 damage points or 10 more damage points scored immediately (257 remaining)
  • Flooding Critical (14.4): Let’s assume for the moment that one of those other Critical Hits was a flooding scoring 4% (13 DP) for a total of 97 hits or 244 remaining; this is more than 25% overall damage so speed is reduced
  • Weapon Critical Hit/Mount Detonation (14.5): There are some reports that “broadside ammunition” was the cause of the fire. Moskva has those huge tubes for the P-500 Bazalt (4M80) [SS-N-12 Mod 1 Sandbox] missiles; if there was a Weapons Critical Hit that scored against this weapon, there is a 10% chance of detonation which would score 71+D6 damage (average 75?) reducing the damage points to 244-75=169 which is just under 50% remaining which means speed is reduced to 16 kts and kicking off another round of Critical Hits (75/169=.44 rounded to .4 for between 0-5 more Critical Hits)—it’s easy to see a snowballing damage effect here especially if more fires or flooding in involved…
  • Fire & Flooding Severity Level (see 14.4): If Moskva suffered at least 16% in Fire and Flooding damage the crew is considered “Overwhelmed.” The damage is considered a “Conflagration” which has a 25% chance every Intermediate Turn (30 minutes) of causing a magazine explosion which can only be avoided by flooding the magazines and pushing ordnance overboard.

So why is everybody seemingly surprised at the outcome of events?

“Naval combat at sea has always been highly lethal to the participants.”

Captain Wayne P. Hughes Jr., USN (Ret.)

Unexpected Lethality?

The late Captain Wayne P. Hughes Jr., USN (Ret.) in his book Fleet Tactics and Coastal Combat Second Edition (Annapolis: Naval Institute Press, 2000) shared a study showing the number of Exocet equivalents (approximately equal to one 3M24) it would take to cripple or sink a warship (see Fig. 6-1, Exocet Missile Equivalents versus Full-Load Displacement for Ships Out of Action and Sunk, p. 160). The table goes up to 7,000 tons but extrapolating the data to ~10,000 tons (Moskva is 9,380 tons standard displacement) indicates that two hits are very likely enough to put Moskva out of action and four or five hits would be sufficient to sink the ship. Assuming two missiles and maybe one sympathetic detonation of ordnance that’s already three hits…with maybe a fourth from fire and flood damage. In many ways the surprise should not be Moskva sinking but if the ship somehow survives.

To be or not TB2

Part of the story of the Moskva attack includes the Ukrainians using a Bayraktar TB2 drone (Harpoon V stats found in The Naval SITREP #56) to “distract” the crew. Personally, I am unsure as to the chances that the Ukraine Navy would operate a TB2 at range (the datalink is rated in Harpoon V as 150 km range), at night, and in bad weather but it’s possible? Some allege the TB2 pulled off Moskva’s radars so they didn’t “see”the attack coming on on the other side. Note that the air search radars used aboard Moskva provide 360 degree coverage. A more plausible explanation to me is that the crew became fixated and focused on a potential TB2 threat and in turn failed (at night and in sea clutter) to see inbound sea-skimming missiles. This is a reality of life in combat and not necessarily replicated in a wargame simulation model.

Which is the real point of this post; wargames can help us understand more about a battle but in the end it cannot capture many human factors. Was Moskva ready for an attack? If not, how long does it take the crew to react (this is a major training issue). Was the crew “distracted” by a TB2 and lacked the discipline to maintain their sector watch and “missed” the inbound missiles? We may never know these answers.

Rocky Reads for #Wargame…K-Pop? Republic of Korea Navy Damage Model vs. Harpoon V (admiraltytrilogy.com)

Thanks to Rex Brynen at PAXSIMS for pointing out some recent modeling & simulation (and wargame) professional reading. One of the articles is from a South Korean journal and discusses the Republic of Korea (ROK) Navy wargame model for ship damage.

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship’s mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.

Although the article is in Korean, many of the graphics are in English, and figuring out what the various algebraic equations likely relate to is possible in places. As I read what I could in the article, it struck me that I had seen much of this before from the Admiralty Trilogy Group (ATG), designers of my beloved Harpoon V naval miniatures wargame.

Cheonghae (“Blue Sea”)

The abstract from the Korean article makes it sound like the original ROKN damage model is quite simple; “In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship’s mission availability is also determined based on predetermined values. I find this a bit astonishing because I can’t think of a single commercial tactical naval wargame in my collection where ship damage is solely a function of tonnage. I mean, even my 1975 version of General Quarters (NavWar Productions) or the 1978 edition of Bismarck (Avalon Hill) has hits against different ship components.

The ROKN study goes on to explain a new methodology that is, “expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.” While this certainly sounds like a “modern” approach, I have to point out that the damage model in the commercial tabletop wargame Harpoon V already does this through a Critical Hit damage mechanism.

Harpoon V from ATG

Fortunately for naval wargamers who want to understand the Harpoon V damage model, ATG publishes on their website a series of presentations from various conventions they attend. These presentations provide some insight into their games, with more than a few being game design “peek under the hood” content. This allows us to do a limited comparison between Cheonghae and Harpoon V.

ATG Harmonization

In the mid-2000’s, ATG realized that the various damage calculation methodologies used in their three principle games (Fear God & Dread Nought for World War I, Command at Sea for WWII, and Harpoon for “modern”) were unsynchronized. Thus, they embarked on a “harmonization” process. A major component of the harmonization process was a rebuild of the ship damage model in the game.

At the 2006 Cold Wars convention, ATG designer Chris Carlson presented, “Weapons Effects and Warship Vulnerability” (Cold Wars 2006) where he identified weapons damage effects on warships as one of the biggest issues in the Harmonization Process. The conclusion of his presentation shows where they are going:

  • Weapon damage effects across the Admiralty Trilogy games are now consistent with basic physical principles
    • –  Convert all damage mechanisms into energy terms
    • –  Use standard explosive theory equations
    • –  Eliminates model distortions (edge effects)
  • Damage point value changes vary based on weapon type and warhead size
    • –  Torpedoes have the greatest change
    • –  Less so for bombs, shells and missiles
    • –  Smaller warheads become more lethal, very large ones are less

At Cold Wars 2008, Chris made another Admiralty Trilogy Seminar presentation titled, “Variable damage Effects in Naval Wargames” (Cold Wars 2008). This is an excellent review of many popular naval wargame systems and how they model damage. More than a few here use a stochastic model, but it is also interesting to see how many use something more. Again, the conclusion provides great insight into where the ATG designers were going, and maybe also how far ahead of the ROKN:

  • Damage variability is a high interest item for players
    • Variability drivers: Location, warhead performance, secondary effects
    • Admiralty Trilogy games don’t use specific hit locations
    • Warhead performance variability isn’t realistic
    • Secondary effects the best option for our games
  • Damage effects are very difficult to model
    • Significant tension between playability and accuracy
  • Revised model gives greater variability in fire and flooding critical hits and in the DC [Damage Control] die rolls
  • Delayed implementation of some critical hit results means ships aren’t instantaneously crippled

Cold Wars 2012 saw another presentation, “Staying Power: Assessing the Damage Capacity of Ships” (Cold Wars 2012). As the presentation says, “Quantifying damage is vexingly complex, and any approach is hard to defend because it is a subjective estimate.” What follows is another review of historical approaches to solving this problem, and how ATG designers are approaching it for their games. Along the way they identify two main models; deterministic and stochastic:

  • Two main approaches to damage effects modeling:
    • Deterministic Model: A ship sinks when the cumulative damage exceeds the ship’s life
      • NWC [Naval War College] Fire & Maneuver Rules and RN [Royal Navy] 1929 Wargame Rules
      • Combat capability and mobility decreases with damage
    • Stochastic Model: A ship sinks, not from cumulative damage, but from a catastrophic event, such as a magazine explosion or excessive flooding
      • U.S. Navy Bureau of Ordnance developed this model during the war
      • Striking Power of Air-Borne Weapons Study, ONI, July 1944
      • Another way to look at it is as a loss of function model

From the limited portions of the Korean study I can read, it sounds like the original ROKN damage model is Deterministic and the goal of the new Cheonghae version is to add Stochastic elements. The ATG approach to damage in their games always has been to create a hybrid. ATG pointed out—back in 2012—that, “Wargaming is best served by a hybrid approach to damage effects (deterministic/stochastic elements).

What’s Old is New Again

Given that I cannot fully read the new Korean journal report there is a fair chance I am missing something here, but I feel that I’m not far off in saying that Korean modeling & simulation may be a step (or more) behind commercial naval miniatures wargaming. I skimmed the journal article bibliography in the vain hope of seeing some reference to miniatures wargaming but alas, no. I find it a bit ironic that when comparing the damage model in Harpoon V to this Korean study, the Harpoon V model, long begrudged in some wargame circles as “too complex,” is in this case the “simpler” model in that it does not need a computer to run nor overtly resort to all the algebraic functions and the like. If one wants to recreate the math behind the ATG model, you can dig through back issues of ATG’s journal, The Naval SITREP, and find articles that show you the way.

There are some (many?) wargamers out there that proclaim Harpoon V (or any of the ATG games) are more simulation than game. I will rise to the defense of ATG here and say that these complaints have not fallen on deaf ears and the ATG staff makes tremendous efforts to make their games playable. Regardless of what you think about their success in doing so, they should nonetheless be recognized as serious game designers who can really math the wicked problems. One can both play and study with ATG naval miniatures wargames. Both players and researchers could benefit from their work with just a little more attention. Surely, adopting (or even adapting) a commercial-off-the-shelf model is less expensive than all the development work that is going into Cheonghae. More importantly, the ATG staff has worked hard to validate their model—I would like to see what Cheonghae says about many of the same cases ATG modeled. Now that would be a great comparison.

Can you figure out how many Damage Points were inflicted here?

Rocky Reads for #Wargame- China as a Twenty First Century Naval Power (Michael A. McDevitt, 2020)

BLUF

A very thorough analysis of the present capabilities of the People’s Liberation Army Navy (PLA Navy). This is perhaps the best single-source compilation of open source analysis on the PLA Navy presently available. Persuasively argues that the PLA Navy is a “blue-water” navy – today. Analytical breakdown offers many opportunities for wargaming.

Naval Institute Press, 2020

Not your father’s PLAN

How often do we hear about “China rising?” If you subscribe to that school of thought then you are in for a surprise if you read China as a Twenty First Century Naval Power: Theory, Practice, and Implications by Michael A. McDevitt, RADM, US Navy (Ret.). In this very recent (late 2020) publication from Naval Institute Press, RADM McDevitt argues that fifteen years of anti-piracy patrols has already made the PLA Navy the second most-capable naval power in the world. He further argues that the PLA Navy is well on track to be a true “world class navy” but 2035, a deadline set by Chinese leader Xi Jinping.

Rear Admiral McDevitt starts out with a discussion of where China’s maritime power ambitions come from. The sources he uses are nothing special; everything is publicly available (although some needed to be translated). This is good grist for wargame designers; understanding what China wants to do on the high seas supports good scenario design.

The second chapter, “Getting Started: Learning How to Operate Abroad” contains the core argument in the book. McDevitt shows how fifteen years of overseas anti-piracy patrols has directly contributed to the development of a highly professional and capable blue-water navy. For wargame designers this is a challenge; so often wargames looking at the PLA Navy seem to dig into the whole “China rising” meme and don’t acknowledge (or refuse to acknowledge) that the Chinese Navy is not “coming soon” but “already here” and far removed from a second-rate coastal defense force that couldn’t even deal with Vietnam.

The next several chapters are probably the best for wargame and scenario design. RADM McDevitt addresses area denial, anti-access and a Taiwan campaign, the South China Sea, and the Indian Ocean in turn. In each section he discusses the what the PLA Navy is charged with accomplishing and the doctrine and equipment they developed to meet the challenge. His discussion of equipment is particularly helpful for wargame designers as each piece of kit is evaluated against what its mission is. This evaluation is far more helpful than just comparing it to the US Navy. The breakdown by area also can be useful for scenario design, and if one puts it all together a larger campaign view is possible.

Pacific Trident III

This book is not the only writing on China’s navy that Rear Admiral McDeveitt delivered in the past year. In February 2020, RADM McDeveitt wrote the final report for the unclassified Tabletop Exercise (TTX) Pacific Trident III sponsored by the Sasakawa USA Foundation. The goal of Pacific Trident III was to explore challenges to the US-Japan and US-South Korea alliances. In that final report, RADM McDevitt foreshadowed some of what he was going to write in China as a Twenty First Century Naval Power. Like in his book, some of the policy recommendations from the TTX are good wargame fodder:

  • Recommendation 3: The United States should consider the merits and risks of adopting a position on the conflicting maritime claims in the South China Sea, persuade other countries to support this position, and develop diplomatic strategies as well as military contingency plans based on these positions (emphasis mine).
  • Recommendation 4: The United States should conduct a policy review of its responses to Chinese aggression against occupied or unoccupied features in the South China Sea. While the details of military actions should be classified, the United States should make it clear that treaty obligations would be invoked by aggression, and could under certain circumstances result in military intervention (again, emphasis mine).
  • Recommendation 6: Planning associated with US military options in support of the TRA [Taiwan Relations Act] recognize the requirement for a rapid expansion of consultative and cooperative mechanisms with Taipei.

Other Views

The Center for International Maritime Security (CIMSEC) was kind enough to publish Toshi Yoshihara’s article, “China as a Composite Land-Sea Power: A Geostrategic Concept Revisited.” The article is adapted from a report by the Center for Strategic and Budgetary Assessments (CSBA), Seizing on Weakness: Allied Strategy for Competing With China’s Globalizing Military. Yoshihara’s thoughts go hand-in-hand with McDevitt:

Imperial overreach is not as farfetched as one might assume, despite China’s impressive wealth creation over past decades. As a classic land-sea power, which faces the seas and shares contiguous borders with its neighbors, Beijing must always stay alert to threats in the continental and maritime domains. This inescapable two-front challenge imposes perpetual opportunity costs: every yuan spent on one area is one fewer yuan available for the other flank and vice versa. The trade-offs between its landward and seaward commitments could impose built-in limits on China’s global plans.

Read it now because the PLA Navy is growing so fast the data will be outdated sooner than later.

Wargame Application

Harpoon V (Admiralty Trilogy Games, 2020)

The discussions in “Chapter Four – Area Denial” and “Chapter Five – Keeping the Americans Away: Anti-Access and the Taiwan Campaign” have lots of potential Harpoon V (Admiralty Trilogy Games, 2020) scenario material. One part in particular that struck me is RADM McDevitt’s assertion that the anti-access strategy doctrine of the PLA Navy is not too unlike the Soviet Union in the Atlantic during the Cold War. This made me immediately think about a 21st Century version of Dance of the Vampires, the Harpoon scenarios and campaign that Larry Bond and Tom Clancy used to support the writing of Clancy’s Red Storm Rising novel. It would be great to see a new 21st century version starring the PLA Navy!

Dance of the Vampires from Admiralty Trilogy Games

“Chapter Six – The PLA Navy and the South China Sea” is perfect update material for South China Sea (Compass Games, 2017). The same can be said for “Chapter Seven – The PLA Navy in the Indian Ocean” and the forthcoming release of Indian Ocean Region: South China Sea Vol. II (Compass Games, 2021).

A 21st Century VitP?

As I read China as a Twenty First Century Naval Power, I appreciated how RADM McDevitt broke down the problem geographically. At the same time, it made me realize that many (all?) modern naval wargames take that same approach. We have wargames on the invasion of Taiwan and confrontation in the South China Sea or Indian Ocean. We also have wargames that can deliver a very fine tactical simulation of a modern conflict. What is lacking (in the commercial hobby wargame space, at least) is a wargame that shows the entire campaign. What I’m thinking about here is something like a Victory in the Pacific-type of overview. Although McDevitt breaks the PLA Navy problem down into discrete geographic areas they are all interrelated: the flow of shipping in the Indian Ocean must travel through the South China Sea to get to the mainland. I can think of no commercial wargame that looks at rolling back the PLA Navy across the globe, or even across the Pacific. Just what is the Plan ORANGE wargame for the 21st century?

#ThreatTuesday – @RANDCorporation “Command and Control in US Naval Competition with China”

RAND Corporation analysts Kimberly Jackson, Andrew Scobell, Stephen Webber, and Logan Ma looks at issues of Command and Control (C2) and the Chinese People’s Liberation Army Navy (PLA Navy) in their research report Command and Control in U.S. Naval Competition with China which is available as a free download. This report is not only a good backgrounder on the C2 differences between the PLA Navy and the US Navy, it also has poses some questions that could make for a good “serious” wargame topic albeit a difficult one to design because C2 and wargames don’t necessarily go well together.

Research Questions

  • How is C2 exercised in the U.S. Navy and the PLA Navy?
  • How are these C2 concepts reflective of service culture?
  • How do these C2 structures support or challenge each nation’s shift to new maritime missions?

Key Findings

The U.S. Navy and the PLA Navy will likely be challenged to fully shift to new strategic postures if they do not adapt their existing concepts of C2

  • The U.S. Navy’s model of mission command appears conducive to counter-power projection missions in theory, but success will likely require increased investments in education and professionalism across the force.
  • The PLA Navy’s rigid control and command structure is likely to come under increasing strain given the relative independence and greater operations tempo required by power projection operations.
  • Currently, many unknowns exist, particularly in understanding how PLA Navy culture is evolving and how the Chinese Communist Party might weigh its preferred method of tight control throughout the PLA against more-effective power projection efforts.

Future Study = Wargame?

The part that interested me as a wargamer was actually the four topics the authors propose for future study:

  • What is more valuable to China: the ability to project power globally or retaining its rigid control and command system?
  • Will the PLA Navy’s increased experience and professional development affect the trust placed in PLA Navy personnel by senior PLA commanders? And how will increased PLA Navy professionalism affect control and command?
  • Would the Chinese Communist Party tolerate a PLA Navy that is more empowered to make independent decisions?
  • Would the PLA Navy taking a mission command approach to C2 be a threat to the United States?

Each of those study topics, in a way, make for a good jumping off point in a more serious wargame. My problem is finding a commercial wargame that gives one a good taste of C2 challenges out-of-the-box. In order to make it more realistic, one often needs to resort to some sort of pre-plotting or double-blind systems with a referee. Let’s be honest, the real questions about C2 are more than just an initiative roll to see who goes first;. A part of me feels like we need an OODA Loop game like Less Than 60 Miles (Thin Red Line Games, 2019) does for the Air Land Battle of the 1980’s in Europe. Amongst my commercial wargame titles some insight may be gained but it will require lots of tinkering:

  • Harpoon V (Admiralty Trilogy Games, 2020): This wargame that verges into simulation is very good at depicting tactical situations but I am not sure the design can really be stretched to show the more operational-level elements of C2 outside of starting scenario conditions.
  • Indian Ocean Region – South China Sea: Volume II (Compass Games, 2021): This forthcoming second volume of John Gorkowski’s South China Sea-series of games is in many ways the 21st Century successor to the 1980’s Victory Games Fleet-series; however, there are no real C2 rules in the game.

Threat Tuesday – Projecting a future US Navy for #wargames

BATTLE FORCE 2045. It sounds like a new science-fiction wargame but it’s actually the name of the the latest future force plan for the US Navy. Secretary of Defense Esper unveiled the plan in early October.

Esper’s Battle Force 2045, which he rolled out during an online event today at the Center for Strategic and Budgetary Assessments, lays out plans for achieving a fleet of 500 manned and unmanned ships by 2045, and a fleet of 355 traditional battle force ships by 2035 – all in a resource-constrained budget environment.

Throughout the rest of October the Center for International Maritime Security (CIMSEC) ran a series of articles assembled under the Fleet Force Structure Series. This series of nine article looked at the future force structure in depth.

In particular, I call your attention to “A Decisive Flotilla: Assessing the Hudson Fleet Design” by Robert C. Rubel which in turn links to the Hudson Institute analysis “American Sea Power at a Crossroads: A Plan to Restore the US Navy’s Maritime Advantage.” This analysis includes several nice tables for a future order of battle that can form the basis of wargame studies.

It would be interesting to see Harpoon V (Admiralty Trilogy Group) data annexes or counters in South China Sea (Compass Games, 2017) for Battle Force 2045.

Sep/Oct #Wargame #Boardgame Acquisitions featuring @gmtgames @hollandspiele @worth2004 @MultiManPub @LnLPub @Academy_Games @FFGames @UnstbleUnicrns @MoonrakersGame

In early September I wrote about how many games might be arriving into the RockyMountainNavy gaming collection given the reawakening of the publishing industry as they struggle to recover from COVID-19.

Boy, did I underestimate myself.

Turns out that between September 1 and October 15 I took delivery of 16 (!) items into my gaming collection. This includes:

  • 8 wargames (+3 expansions)
  • 3 boardgames (+1 expansion)
  • 1 accessory

I also diversified my acquisition chain. In addition to Kickstarter and publisher pre-order systems, I also used a local flea market, online digital, BGG trading, publisher direct sales, and (gasp) my FLGS!

Wargames

Washington’s Crossing (Revolution Games, 2012) – A not-so-complex look at the Trenton Campaign of 1776. My more detailed thoughts are here.

Flying Colors 3rd Edition Update Kit (GMT Games, 2020)(Expansion) So many Age of Sail games take a super-tactical view of ships that playing them can become unwieldy. Flying Colors takes a more ‘fleet commander” point of view; here you can be Nelson at Trafalgar, not Captain Hardy. The 3rd Edition Update Kit brings my older v1.5 up to date with the latest counters and rules, allowing me to set sail for new games in the future.

White Eagle Defiant: Poland 1939 (Hollandspiele, 2020) – The follow-on to the gateway wargame Brave Little Belgium (Hollandspiele, 2019). Don’t let the low complexity of the rules fool you; the game is full of impactful decisions. I have more thoughts here.

French and Indian War 1757-1759 (Worthington Games, 2020) – Another entry in my collection of Worthington block wargames. Simple rules but deep decisions. It’s been a long-time since I labeled a wargame a “waro” but this one crosses over between the wargame and boardgame crowds.

Harpoon V: Modern Tactical Naval Combat 1955-2020 (Admiralty Trilogy Group, 2020) – More a simulation model than a game. I’ve played and owned Harpoon titles since the early 1980’s. Can’t help myself; I love it.

Iron Curtain: Central Europe, 1945-1989 (Multi-Man Publishing, 2020) – Another entry in the Standard Combat Series from MMP. I like the multiple eras of play and the ‘Road to War’ rules that deliver replayability in a (relatively) small package.

Konigsberg: The Soviet Attack in East Prussia, 1945 (Revolution Games, 2018)Acquired via trade. I like chit-pull games as they are good for solo play. I am also interested in this title because of the time period; I have played Operation Barbarossa to death and am interested in a late war perspective when the Soviets were on the offensive and it was the Germans rocked back on their heels.

Corps Command: Dawn’s Early Light (Lock ‘n Load Publishing, 2010)Acquired via trade. Got through a trade more on a whim than with any real thought. First look is a very simple ‘Cold War Gone Hot’ wargame. Realistically it has only seven pages of rules!

Nations at War: White Star Rising (Lock ‘n Load Publishing, 2010) – I don’t really need another World War II tactical game system; I’m very happy with my Conflict of Heroes series from Academy Games. Acquired through trade with no real big expectations. First impression is this platoon-level game is reminiscent of PanzerBlitz (Avalon Hill, 1970) but with chit-pull activation and command rules (both of which I really like). Maybe some interesting potential here, will have to see…. (Acquired at same time were two expansions: Nations at War: White Star Rising – Operation Cobra and Nations at War: White Star Rising – Airborne)

Boardgames

One Small Step (Academy Games, 2020) – I’ve said it before and I’ll say it again; worker placement games is not really my thing. However, I really do like One Small Step. Not only does the theme engage me but the team play version of worker placement makes it a good game night title for the RMN household.

Star Wars: Rebellion (Fantasy Flight Games, 2016) Acquired via flea market. I jumped at an opportunity to get this game via a local flea market at an excellent price. Thematically excellent but I still have doubts concerning gameplay. It does create a very good narrative though….

Here to Slay: Warrior and Druid Expansion (Unstable Games, 2020) (Expansion) Here to Slay is the #1 played game in the RMN home. The RMN Boys (and their friends) love it. The game is far from perfect; like many others I don’t feel it is anything like an RPG as it proclaims and it’s too easy to win with “six classes in your party” versus slaying three monsters. Maybe this new expansion will change that with a bit more focus on the warrior class. Maybe….

Moonrakers (IV Games, 2020)Fresh arrival. Bought because I keep looking for a decent Traveller RPG-type of boardgame or something that captures the same vibe as Firefly: The Game (Gale Force Nine, 2013). My other attempts to find these types of games, Scorpius Freighter (AEG, 2018) and Star Wars: Outer Rim (Fantasy Flight Games, 2019) were less-than-successful. This title just screams OPA in The Expanse. Playing it will have to wait as there is a backlog of games in front of it in the to-play queue (obvious from the above).

Accessories

Sirius Dice: Spades (Sirius Dice) – I picked these up sorta on a whim. They look and feel good. If I ever get back to playing RPGs they may come in handy.

A Modern Simulation #Wargame – Harpoon V (admiraltytrilogy.com, 2020)

How many wargames do you know get a mention in a major mainstream publication, like Forbes? In August of 2020, the ‘new’ Harpoon V naval miniatures wargame from Admiralty Trilogy Games got just such an article. So what makes Harpoon V so special?

Way back in 1982 I was a wee middle schooler who had started wargaming just a few years before. The major titles in my collection were the Panzer/88/Armor series by James Day from Yaquinto Publishing and Star Fleet Battles (Task Force Games, 1979). That same year, the United Kingdom and Argentina fought the Falklands War. The extensive media coverage fascinated me to no end, and not long after I found a copy of a miniatures wargame called Harpoon II (Adventure Games, 1983) and its supplement Resolution 502. What immediately struck me about Harpoon II was that the game was more a simulation than, well, a game.

One of the greatest news magazine covers ever….

The next year I read the book Hunt for Red October by author Tom Clancy. I immediately started to recreate the scenes of Red October in Harpoon II. In 1986 I read Clancy’s Red Storm Rising and again was struck by the bug to recreate the scenes using Harpoon. Just a year later, Harpoon 3rd Edition (GDW, 1987) hit the shelves and I eagerly bought the base game and all the expansions. I continued to follow (reinvesting every time) when the title shifted to Clash of Arms as they published Harpoon 4 (1997). So it should come as no surprise that I am once again investing in the latest version, Harpoon V (Admiralty Trilogy Games, 2020).

My Harpoon Collection (original image courtesy Admiralty Trilogy Games)

What keeps me coming back? Well, the Harpoon series is less a game and more a simulation. Look at how the current publisher describes Harpoon V:

Harpoon is the flagship of the Admiralty Trilogy Group’s games. First published in 1980, it has undergone several major revisions, with the last, Harpoon 4.1, being printed in the late 1990s. Although the system has remained fairly stable, naval technology has continued advancing, and there have been further developments in the game systems as more information has been acquired. It is planned plan to issue a new edition, Harpoon 5, sometime in the near future consolidating this knowledge and standardizing Harpoon with the other products.

The era of modern naval combat began on October 21, 1967 when Egyptian missile boats launched four Soviet made Styx surface-to-surface missiles and sank the Israeli destroyer Elath at a range of 13.5 nautical miles. The face of naval warfare changed forever!

Harpoon 5 handles all aspects of modern maritime combat: surface, sub-surface, and air. Harpoon 5 is a system of detailed but comprehensible rules covering the many facets of modern naval actions. Consistent rating systems and evaluations of the capabilities of modern naval vessels, aircraft, submarines, and helicopters make it possible to achieve realistic results when simulating known situations, by extension Harpoon 5 also achieves realistic results with hypothetical scenarios.

Harpoon 5 can answer questions like:

Are carriers powerhouses or sitting ducks?
Can transatlantic convoys survive in a modern wartime environment?
In the cat-and-mouse games between US and Russian submarines, which is better?

As much as Harpoon V is a simulation, I have to give kudos to the design team to trying to make the game more ‘playable’ without losing ‘realism.’ The key to this balance is in the ratings system of platforms, weapons, and equipment that takes into account different technological eras. A simple “Generation’ rating for many weapons and combat systems (such as radars) accounts for how ‘smart’ they are. Thus, one can see the difference between a 500 lbs. bomb as it transforms from a ‘dumb’ unguided bomb in Vietnam to a laser-guided version in the Gulf War to a ‘smart’ GPS-guided munition of today. Or how it is much easier to spoof a Former Soviet Union air search radar on an exported missile boat in the 1980’s than it is to detect a modern Low Probability of Intercept (LPI) surface search radar.

Critics of the Harpoon series often cry the game is unplayable. Well, I challenge them to consider if they are judging the series as a war game or a simulation wargame. I argue that Harpoon, being more a simulation, by necessity uses a more complex model that requires more player manipulation. Many time in wargames, the model is simplified or heavily abstracted in the name of playability. There is nothing wrong with that as long as the ‘abstraction’ is done purposefully. The Harpoon series, because it leans more heavily into the simulation than gaming aspects of the design, can seem chart-heavy. I agree with many critics who say the game can be made more ‘playable’ if in a computer version, much like Command: Modern Air/Naval Operations (CMANO). That said, I like the player manipulation of the model, even if it costs me some playability. Besides, I don’t have an awesome gaming computer to run all the great graphics of those other games; indeed, my MacBook struggles even when running Table Top Simulator! That’s OK; I use the many nice counters from my Clash of Arms Harpoon 4. More recently, I have looked at investing in Paper Forge printable standees like their Modern US Navy Cruisers set.

CMANO – Quite honestly it’s computerized Harpoon

I will also admit that I look at Harpoon V as more a ‘professional’ wargame than a recreational one. No, I do not work in a DoD wargaming organization but even I use Harpoon for what-if exploration of current issues. As a matter of fact, Persian Incursion (Clash of Arms, 2010) is literally air strike Harpoon with a political game bolted on. That is the power of Harpoon!

Harpoon – without ships but lots of strike aircraft and geopolitics

Then there is the investment. The base rules are available from wargamevault.com for $20. However, to really play one needs to buy the data annexes. The first four, America’s Navy, Russia’s Navy, American’s Aircraft, and Russia’s Aircraft are available in pdf form for $16…each. That collection is great for replaying the Cold War but, let’s face it, the real match-up most modern naval gamers want to play out today is the US versus China. So, ATG, when is that data annex going to be available?

Well, look at that! Bestseller on Wargame Vault (image captured Sep 26, 2020)
