Project history: Ò class design was developed on the basis of Salmon and Sargo classes with increased to 10 TT number and strengthened pressure hull. In remaining they were close to prototype. Double-hulled, operational diving depth was 90 m ( designed destruction depth was 150m). Diesels were directly connected with propeller shafts.

They were built under FY1939 (SS198-203) and FY1940 programs (SS206-211).

Modernizations: 1942 - 1943, all survived: CT was rebuilt; - 1 x 1 - 76/50 or 1 x 1 - 127/51, 2 x 1 - 12.7/90; + 1 x 1 - 102/50 Mk 9 or 1 x 1 - 127/25 Mk 17, (1 x 1 - 40/56 Mk 1.2, 1 x 1 - 20/70 Mk 4) or 2 x 1 - 20/70 Mk 4, SD, SJ radars

1.1946, SS198-200, 203, 206: 10 - 533 TT (6 bow, 4 stern, 24), 1 x 1 - 102/50 Mk 12 or 1 x 1 - 127/25 Mk 40, (1 x 1 - 40/60 Mk 3, 1 x 1 - 20/70 Mk 10) or 2 x 1 - 20/70 Mk 10, SD, SJ radars, QCG sonar

Naval service: Grampus was lost by unknown cause in February-March, 1943, most likely, sunk 5.3.1943 off New Anglia by Japanese destroyers Minegumo and Murasame. Triton 15.3.1943 was sunk N off Admiralty Islands by Japanese destroyers. Grenadier 21.4.1943 was badly damaged by Japanese aircraft in Malacca strait by Japanese aircraft and 22.4.1943 was scuttled by own crew at Penang. Grayling was lost by unknown cause in August-September, 1943, possibly, sunk by Japanese passenger vessel Hokusu Maru 9.9.1943 off Luzon. Trout 29.2.1944 was sunk SE off Okinawa by Japanese destroyers Asashimo, Kisninami and Okinami. Grayback was lost in February-March, 1944, possibly, sunk 26.2.1944 in the East China Sea by Japanese torpedo bomber B5N.
