USS FRANK CABLE (AS-40) MISSION: Provide mobile base facilities capable of furnishing maintenance and logistic support for nuclear attack submarines, including the SSN 688 class. COMMENTARY: Naval auxiliary ships carry out a variety of missions in support of combatants. Included in this category are tenders. Along with destroyer tenders, the submarine tenders are the largest of the active auxiliaries. Their crews are formed mainly of technicians and repairmen. The EMORY S. LAND and L.Y. SPEAR classes were designed and fitted to accommodate attack submarines, and can service four submarines moored alongside simultaneously. USS PROTEUS was commissioned as a diesel sub tender in 1944 then overhauled and reconfigured in 1959-60 to service FBM subs. In 1981, she was retired from FBM service and is now an attack submarine tender. The HUNLEY and SIMON LAKE classes are configured especially to service FBM submarines. L.Y. SPEAR & EMORY S.
