Project TM-200 Motor Torpedo Boat

TL;DR:
Coastal vessel, large torpedo boat with 6 .50cals.

History:
Project 200 was a wartime project to create a standardized hull design for MTBs and subchasers. Because of wartime circumstances, the design had to be able to constructed from either steel or wood, and needed a maximum beam of ~4m to be rail transportable as they would be built by inland river shipyards. A series of designs based first on the D-3 eventually resulted in Project 200 in November 1942, designed by Shipyard No. 640 at Sosnovka. Like other Soviet boats in the late-war, these ships were to use lend-lease Packard diesel engines, which were more reliable and powerful than earlier Soviet designs. There were 4 designs: OD-200 and OM-200, the subchaser designs (OD-200 is in-game too), and TD-200 and TM-200, the torpedo boat designs.

TM-200 was the steel torpedo boat design, which was to be built at shipyard No.341 in Rybinsk. Its loadout was identical to the wooden TD-200 type, having 3 twin DShK machine guns and 21 inch torpedo tubes, considerably more powerful than other Soviet torpedo boats. Interestingly, the two torpedo boat designs used different DShK mounts, the TD-200 2UK mounts and TM-200 MTU-2 mounts. The first TM-200 boat, TK-450 โ€œYungaโ€, was completed in 1944 and sent to Batumi for trials. Because of poor construction and propeller design issues, it was only able to reach 34 knots, 4 less than projected. The following vehicles resolved these issues and reached the projected 38 kts. In total only 24 ships were built, considerably less than the OD-200 and TD-200 designs.
