Torpedo Kater TKA D-3

In 1939, the Design Bureau of Ship Plant No.5 at Leningrad was ordered to develop a fast, long-range and seaworthy torpedo boat for the Red Navy.
Chief Designer L.L.Ermashabyl chose a wooden hall driven by three GAM-34 engine with 750 hp each and armed with two 533mm torpedo and two 12.7mm DShK hMG for AA defense.
In 1941, after successful tests, the first series production was launched at Plant No.5 and a plant at Kirov with 25 units.
From 1943-45, second series production followed with 47 units, differing from the early series by three U.S. Lend-Lease Packard engines with 1200 hp each yielding a top speed of no less than 45 knots per hour.
Additionally, a further 20mm Oerlikon or ShVAK cannon was supplied for AA defense.
For unknown reasons, some TKA were later rebuild to SKA patrol boats with the two torpedo launchers replaced by a shielded 37mm 70-K AA gun.
Except for the prototype serving with the Black Sea Fleet, all TKA D-3 were supplied to the Baltic and Northern Fleet where they successfully participated at the ampibious landings at Petsamo, Vyborg and the Moon Archipel.
However, the D-3 was passed in popularity by the better known TKA G-5 which relied on a much more streamlined steel hull developed by famous aircraft designer Tupolev.
