Project history

One of standard British-built MTBs of WWII era. Wooden-hulled.

Modernizations

1942: all survived boats with Hall Scott engines were re-engined with 3 Packard engines

1942-1943, many completed 1940-1942: + type 286PU radar

1943, survived MTB31 - 40: - 1 x 2 - 12.7/62; + 1 x 1 - 20/70 Oerlikon Mk II/IV

1943-1944, most earlier boats: - type 286U or type 286PU radar; + type 291U radar

1943 - 1944, survived MTB73 - 98, 222 - 245: - 1 x 2 - 12.7/62; + 1 x 2 - 20/70 Oerlikon Mk II/IV, 1 x 1 - 20/70 Oerlikon Mk II/IV

1/1946: 1 x 1 - 57/43 Mk VII (MTB523, 525, 533), 1 x 2 - 20/70 Mk XII or 1 x 1 - 20/70 Mk III or (1 x 2 - 20/70 Mk XII, 1 x 1 - 20/70 Mk III), 2 - 450 TT or 2 - 533 TT, 2 DC, type 291U or type 293 radar

Naval service

1941: MTB40K became motor minesweeper attendant craft MAC7

1943: MTB31, 32, 34 became controlled targets CT22, 24 and 23

1943: MTB361 became CT36

1945: MTB353, 354 became CT38, 39; MTB358, 359 became CT34, 35; MTB361, 362 became CT36, 37; MTB531, 537 became CT44, 45

1950: MTB1002 was reclassified to FPB (fast patrol boat).
