Admiralty Trilogy Group (ATG) continues to push out new material for their trilogy-plus series of naval miniatures wargame rule sets: Dawn of the Battleship (1890-1905), Fear God & Dread Nought (1906-1925), Command at Sea (1926-1955), and Harpoon V (1955-Present). In the first half of 2026 I took in two new ATG products, both of which continue to deliver detailed material to support wargaming with naval miniatures.
Japan’s Self-Defense Forces: Japanese Ships & Aircraft, 1955-2026 is a 95-page digital book that serves as the Data Annex repository for Japan’s Self Defense Force—particularly naval and air forces—since 1955.
The book has more than just the usual Annex A through Annex Z data tables on ships, aircraft, weapons, radars, sonars, and tactical datalinks. Included also are sections on the organization of the ships and aircraft of the Japanese Maritime Self Defense Force (JMSDF). There is also a section on the organization of the Air Defense Command of the Japanese Air Self Defense Forces (JASDF). This means Annex B Aircraft includes JASDF and JMSDF airframes—and even helicopters from the Japanese Ground Self Defense Force (JGSDF). The information cut-off of the content is April 2026. It is amazing to see how much has already changed!
My second new ATG product is Issue #70 of The Naval SITREP: The Journal of the Admiralty Trilogy Game System released in April 2026.
The Naval SITREP Issue #70 is another digital book that deliver 32 pages of content for Dawn of the Battleship (scenario), Fear God & Dread Nought (scenario), Command at Sea (two scenarios plus an article on aerial searching of the Imperial Japanese Navy carrier force in World War II and another on French cruiser submarines), and Harpoon (China’s armed container ship testbed, a scenario, a rules change for Very Low (VLow) bombing, and an article on laser weapons on sharks at sea). There is also new material for the Harpoon-derived wargame Persian Incursion such as new aircraft loadouts and new data cards. Several books are reviewed meaning my Naval Institute Press or Amazon membership got “exercised” yet again.
Persian Incursion explores the political and military effects of an Israeli air campaign against Iran to prevent them from building a nuclear weapon. It uses rules adapted from Harpoon to resolve the military action. But its goal is to look beyond the military action by modeling the political and intelligence actions and consequences of a potential political conflict by including a card-based political component to the game.

Perhaps the most interesting article in Issue #70 is the Harpoon scenario, “You Say Diaoyu, We Say Senkaku” which pits China (using data from Harpoon V China’s Navy) against Japan (using data from Japan’s Self Defense Forces above) in a situation all-too-likely today. The scenario was run at Historicon 2024 but what stands out to me is that this is one of the first scenarios I can recall where rules for the DF-21 anti-ship ballistic missile (ASBM) kill chain are laid out.
By the way, I am still searching for some good 1/2400th scale STL files for 3D printing my own ships to sail into battle on my gaming table….
