Threat Tuesday / #Wargame Wednesday / #RPG Thursday (a few days early) – Underground Missile Base to Weaponeer and Perfect Villains Lair

This week Iran unveiled on YouTube their ‘underground barrage missile base:”

As if one video isn’t enough inspiration here is a second (minus the vertical missiles). Obviously filmed pre-COVID. I really like the ones wearing sunglasses deep inside a tunnel!

One missile wonk on Twitter even made a helpful graphic:

For Threat Tuesday this is an interesting way way to deploy missiles. The US certainly learned the danger of storing a liquid-fuel missile in an underground silo forty years ago when a Titan-II ICBM blew up in Arkansas.

For Wargame Wednesday (a day early) this is an interesting target to weaponeer. In the wargame Persian Incursion from Clash of Arms/Admiralty Trilogy Group players can use the rules from Harpoon 4.X to strike underground bunkers. These look much deeper and more difficult. Shades of Star Wars here – deliver that torpedo into the shaft!

For you roleplaying game players looking for RPG Thursday (2 days early) this looks to be a perfect villain’s lair for use in your James Bond 007 Roleplaying Game (Victory Games, 1982) or any modern espionage RPG setting.

#TravellerRPG Tech – Beams & Missiles & Casters, oh my!

In Classic Traveller RPG and the more recent Cepheus Engine implementation of the rules spacecraft weapons generally are either Missile or Beam (lasers, particle beams, fusion beams). In Traveller 5 another class of weapons, Data Broadcasts or Beamcasts, is introduced. As advanced as Traveller technology is, it appears that Humaniti is too inventive.

In February 2019, the Defense Intelligence Agency published Challenges to Security in Space. This volume is part of their Military Power Publications. As befits an intelligence agency, the focus is on, well, the threat:

Space-based capabilities provide integral support to military, commercial, and civilian applications. Longstanding technological and cost barriers to space are falling, enabling more countries and commercial firms to participate in satellite construction, space launch, space exploration, and human spaceflight. Although these advancements are creating new opportunities, new risks for space-enabled services have emerged. Having seen the benefits of space-enabled operations, some foreign governments are developing capabilities that threaten others’ ability to use space. (Executive Summary)

One graphic in particular stood out to me; it concerns Kinetic Energy and Orbital Threats:

Challenges to Security in Space, DIA, p. 10

In Traveller RPG terms, Kinetic Energy Threats are covered by Missiles. However, several of the Orbital Threats shown are not immediately represented in Traveller or Cepheus Engine.

Lasers, KKVs, and Robotic Mechanisms are easily portrayed using the existing Traveller or Cepheus Engine rule set. Using Traveller 5 one can get to Radiofrequency Jammers using Datacasters.

High-power Microwaves is not easily found in the rules. This weapon is maybe a form of an EMP device:

The electromagnetic pulse (EMP) weapon, also called the e-bomb, or the radio flash weapon, is capable of disrupting or damaging the circuitry of most electronic devices.

The weapon accomplishes this by sending either a single pulse or a series of fast, high-powered pulses of electromagnetic energy in the range of 100 MHz to 20 GHz. These pulses are similar to a lightening strike or a nuclear blast. The power level of these pulses can be several hundred megawatts (MW). The EMP weapon has a range of at least several hundred meters, but reportedly can be transmitted up to 15 Km.

The specific method by which the pulse attaches to the circuitry is called coupling. Coupling is simply the binding of an energy wave onto a conductor. There are two types of coupling. The first is called front door coupling and it happens when the energy wave binds to the antenna of a device. The other type is called back door coupling. It occurs when the wave binds to external components such telephone lines, network cables and power lines.

It can also occur with ports on the back of a computer, such as serial ports. After the energy binds, it then moves through the circuitry, frying or disrupting sensitive internal components, such as crystal diodes, ICs, mixers, logic circuits, etc.

The precise targeting of electronic devices can be accomplished in the following way: First the EMP weapon can be aimed in a specific area. The primary factor is not the power of the pulse, but the ability to focus the output. The energy must be accurately deposited at a certain range to be effective.

Next, it can be configured to send a single pulse consisting of a specific frequency, which will only destroy the circuitry of a device that functions on that frequency. In this manner, if an operator has the frequency signature of a target device, then only that single device will be affected, while others in the area remain unharmed.

Furthermore, a series of fast pulses consisting of multiple frequencies can be sent to an area, which will affect the circuitry of all devices operating on those frequencies. This type of delivery is referred to as an ultra wideband pulse (UWBP). It can be adjusted to cover large areas, even an entire city. (newworldwar.org)

In Traveller/Cepheus Engine terms this sounds like a weapon that can be used to destroy sensors or otherwise fry circuits. At higher Tech Levels, the EMP pulse could even be tailored to attack specific components of a ship.

Chemical Sprayers looks interesting. Even spraying something as simple as water in space may create ice that could be lethal at high velocities. Or maybe its chemicals to coat optics or smear solar cells? Other sci-fi ideas may be a chemical that eats at door seals (depressurization?). Maybe what we have here is an early form of the Sandcaster?

Of course, the lowest-tech solutions are also effective. Where in Traveller was there ever harpoons in space?

Threat Tuesday – Un’er’s New Missile

NorK Missile Launch, June 2015
NorK AntiShip Missile Launch, June 2015

The world’s favorite naughty boy, North Korea’s Kim Jong Un, showed off a some new naval toys this weekend. He watched a firepower demonstration where a “new” antiship cruise missile, which some in the press call the “KN-01”, was launched. The missile looks to be a near-copy of conventional Russian designs. If one looks close, you can see a radar reflector set up on the target (gotta make sure you get a hit for the big guy or you’ll end up a dead guy yourself).

For Harpoon 4 players, just use a Russian Kh-35 and see what it gets you!

Threat Tuesday – NorK ICBM?

The NorKs remain defiant, even after their satellite launch attempt failed. A popular mantra in policy and press circles leading up to the space launch was that the NorKs can use space launch technology for offensive long-range ballistic missiles. The space launch failed and the NorKs are looking to regain lost face. So on April 15, guess what the Un’er rolls out at a big parade for Grand-Daddy?

North Korean leader Kim Jong Un delivered his first public televised speech Sunday, just two days after a failed rocket launch, portraying himself as a strong military chief unafraid of foreign powers during festivities meant to glorify his grandfather, North Korea founder Kim Il Sung.

Oh, since the AP has basically been co-opted by the NorKs (see One Free Korea here) that caption is less-than-helpful and doesn’t tell the real story. Let’s see how Reuters captioned it:

State media film a rocket carried by a military vehicle during a military parade to celebrate the centenary of the birth of Kim Il-sung in Pyongyang April 15, 2012. South Korea’s Yonhap news agency and YTN TV later cited military sources and analysts as saying the rocket is a new long-range missile, presumed to be a ballistic missile with a range of 6,000 km (3,700 miles). (Reuters)

Joshua over at Arms Control Wonk posted the following details:

Those are two three-stage missiles carried on large, eight-axle vehicles. YTN describes them as being about 18 m long and about 2 m in diameter. That’s much smaller than the TD-2 — not bigger, as the Chosun Ilbo had claimed. (Really, who could imagine a mobile missile almost half the length of a football field?)

Joshua also has an article up at 38 North that he wrote before the April 15 parade that talks about the NorKs getting ready to unveil a new ICBM. Good background information there.
