Project history

"Seagoing armoured motor gunboats". Wartime design was created in 1941-1942 on the basis of pre-war project 138, originally adapted for building in conditions of beleaguered Leningrad: in particular, she had simplified rectilinear hull form, lend-lease engines and turrets from T-34 tank as originally was planned. Boats differed by strong armament: under design 2 76mm guns, 1 37mm MG, 2 82mm mortars; but already since lead boats they instead of mortars had 45mm guns. Protection of serial boats frequently differed from designed: armour plates which are available at present on a factory were used. The design was approved 15.9.1943: one week prior to commission of lead boat.

Survived MBKs in 1946-1949 were classified as small gunboats.

Ship protection

Belt had 52-50mm thickness abreast citadel and was closed by 14mm fore and 48-30mm aft bulkheads, it was connected with 35-30mm deck. Ship ends outside citadel were protected by 18-14mm belt and 18-12mm deck.

Modernizations

None.

Naval service

BK-504, BK-509 and BK-514 were sunk by German mines 4.7.1944.
