Cutlass 254k British subs visits Norfolk circa middle 1950's plus. Submarines lined up on the pier from outboard to inboard are: Cutlass (SS-478) and Sea Leopard (SS-483) with step sails. Followed by the Sealion (SS-315) & several SSR's which might be the Tigrone (SSR-419) and Burrfish (SSR-312). Both boats are in the Migraine I SSR version. If the last SSR is indeed the Burrfish, then this picture would have been taken sometime in the late spring of 1956.
The USN sailors are in dress whites (indicating the springtime changeover to whites), and the Burrfish departed Norfolk for the last time on 5 June 1956, headed for New London and decommissioning. The tender is Sierra (AD-18), which was always located at the next pier down from the sub pier.
