Being a Navy guy, I have long played naval wargames. For modern tactical naval combat nothing beats Harpoon in my book. I started way back with Harpoon II in 1983. The current version is Harpoon 4 first published by Clash of Arms in 1997 and now by Admiralty Trilogy Games.
I am also a fan of the Asia-Pacific theater, having spent way too many years in the Western Pacific. The Harpoon system does have a “sourcebook” for the Pacific Rim in the expansion Sea of Dragons, but it was published way back in 1997!
With the news that China is set to launch it’s first indigenously built carrier any day now, I got to thinking about how one would update at least the Chinese People’s Liberation Army Navy (PLA Navy) order of battle information in Sea of Dragons. Fortunately for wargamers, there are several excellent publicly available sources to help!
The first is from the Office of Naval Intelligence. In 2015, ONI published The PLA Navy: New Capabilities and Missions for the 21st Century. In addition to the publication itself, ONI also has provided useful graphics and videos and maps on their website. This should be every wargamer’s first stop when looking at the modern PLA Navy.
But today is 2017, and the Chinese have not been resting on their laurels since ONI printed their book. In another stroke of luck, gamers can look to Ronald O’Rourke of the Congressional Research Service. China Naval Modernization: Implications for U.S. Navy Capabilities—Background and Issues for Congress is updated several times a year and is one of the best running estimates of the threat. It is a very useful publication for bringing the ONI 2015 report forward to today.
I would also point the wargamer to Andrew Erickson’s excellent website. Dr. Erickson is on the faculty of the Naval War College, China Maritime Studies Institute. He specializes in using Chinese-language sources to study the PLA Navy and is a prolific speaker and author on the topic.
Between these three sources one should be able to update Sea of Dragons and get a better sense of what the PLA Navy would look like in a tactical naval game like Harpoon 4. One probably also will need to purchase back issues of The Naval SITREP magazine from the Admiralty Trilogy Group on a site such as Wargame Vault to get many ship characteristics.

Even if you are not a digital gamer, bear in mind that the PC simulation “Command: Modern Air/Naval Operations” (CMANO) is a treasure trove of information. Its platform/weaponry database and its scenario design features made me get it in spite of its steep price! And it includes enough data to game into the 2020s.
