Project history: Salmon class submarines represented increased version of Ð class with more powerful machinery, two additional stern TTs (8 at all) and increased to 24 torpedo stowage. In their construction it have returned to diesels with mechanical shaft drive (hydraulic more precisely, through a special clutch). The similar decision was a tribute to the fears advanced by a number of experts, about insufficient damage tolerance of electrical transmission which could be easily incapacitated at any power cable damage. Double-hulled, built under the FY1936 program.
Under FY1937 and FY1938 programs 10 more boats of very close Sargo class were built. They at the expense of small increase in a stock of fuel had enlarged endurance. Four boats of the FY1938 program (SS194-197) often were outlined into separate Seadragon sub-class. They again had diesel-electrical engine, besides, almost on 30% larger capacity of batteries allowed to be underway 48hrs with 2kts speed in submerged position.
Modernizations: 1942 - 1943, all survived: CT was rebuilt; - 1 x 1 - 76/50, 2 x 1 - 12.7/90; + 1 x 1 - 102/50 Mk 9 or 1 x 1 - 127/25 Mk 17, 2 x 1 - 20/70 Mk 4, SD, SJ radars
1.1946, SS188-190, 192, 194, 196: 8 - 533 TT (4 bow, 4 stern, 24), 1 x 1 - 102/50 Mk 12 or 1 x 1 - 127/25 Mk 40, 2 x 1 - 20/70 Mk 10, SD, SJ radars, QCD sonar
Naval service: Squalus foundered 23.5.1939 during trials, salvaged and commissioned in May, 1940 under new name.
Sealion 10.12.1941 was badly damaged by Japanese aircraft and 25.12.1941 scuttled at Cavite (Philippines). Sculpin 18.11.1943 was scuttled N of Truk being badly damaged by Japanese destroyer Yamagumo. Seawolf 3.10.1944 was erroneously sunk by destroyer escort Richard M. Rowel. Swordfish was lost by unknown cause in Pacific in January, 1945.
Searaven 11.9.1948 was sunk as target.
