Ship project history: Further development of Gato and Balao classes. Project of new submarine received enhanced internal subdivision on compartments, hull durability also was raised, that has led to displacement growth approximately on 35-40t. In remaining they differed from predecessors a little. Last series, from SS475, was projected on the bigger operational diving depth (135 m, maximum permissible 225m), besides, they had increased to 28 torpedo stock.

In total in 1942-1943 146 new submarines were ordered (SS417-562), however in 1944-1945 building of 112 boats (SS427-434, 438-474, 491-515, 517-521 and 526-562) was cancelled. In 1946 also SS516 was cancelled, and building of SS436 and 437 was suspended and eventually they were sold for scrap incomplete. As a result 31 boat were completed only.

1946 - 1953, part of submarines was converted to radar pickets by Migraine program. "Migraine" submarines can use their radars only when surfaced, later converted submarines had snorkel and can use radars in cruise position. "Migraine III" submarines received longed hull.

 

Migraine: one submarine was commissioned in this configuration and one was converted, as follows
