Leap Day Submarine History

Only a few events of submarine history have occurred on a leap day.


On 29 February 1944, USS Cavalla (SS-244) was commissioned.



On 29 February, 1992, USS Jefferson City (SSN-759) was commissioned.

Interestingly enough, both of these events have a connection to AIMM.

Like Razorback, Cavalla was present at Tokyo Bay, Japan on 2 September, 1945, when the Japanese surrender was signed aboard the battleship USS Missouri (BB-63). Cavalla is now a museum in Galveston, TX.

AIMM staff member Joe Mathis was stationed aboard Jefferson City during his career.
