The other 3 boats are from outboard in Migraine II Requin (SS-481) and Migraine I Burrfish (SS-312) and Tigrone (SS-419). The order of the last 2 might be reversed.	Text contributed by Larry Derouin.

145k	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 56, 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.	Photo courtesy of John Hummel. Photo i.d. & text courtesy of David Johnston (USNR).
