| Stickleback | SS-415 | 20 May 1958 | Collision with USS Silverstein | Oahu, Hawaii |
| Thresher | SSN-593 | 10 April 1963 | Exact cause unknown; one theory is a seawater leak led to a reactor plant shutdown, compounded by a heavy trim (excess negative buoyancy) and an inadequate ballast tank blow system. Another theory is that a reactor plant scram occurred for tests; a flaw caused an inability to operate key reactor valves and other valves, which prevented emergency surfacing or a problem in the procedures for a scram caused the inability to operate a very important steam plant valve causing a loss of propulsion. Any of these problems could have caused the boat to sink beyond crush depth. | 200 nautical miles (370 km) east of Cape Cod, Massachusetts |
