Following the war, the berthing spaces of the South Boston Naval Annex were used for the process of inactivation and storage of ships no longer needed in commission with the peacetime US Navy. At it's peak in the mid-late 1950's the Annex was the storage site for 20 Light & Escort Aircraft Carriers, 9 Cruisers and numerous Destroyers. During this period, the Annexs' drydock and Southeastern-most berth were used for overhauls and repairs to active service Navy ships, a role continued today.

Boston Navy Yard is in South Boston, along Boston Harbor. Both of the yards were built, to a large extent, on filled land. The main yard went from 123 acres to 143 acres 1942. The annex was increased from 106 acres to 231 acres. This 1888 map displays the annex area addition. Todays land fill is even greater, including the areport.

At the South Boston Annex, work was started in March 1940 on a quay wall and wharf and on a machine shop 1,300 feet long and 500 feet wide. The following spring a new power plant project was undertaken, to provide six boilers, a compressor and a primary connection to the Edison system.

An additional waterfront project, comprising two 980-foot timber piers and a steel sheet pile bulkhead, was started in the sumer of 1941, followed in September by construction of an additional shop 420 feet long and 120 feet wide.
The Boston Navy Yard Annex was 2 miles down river from where the USS Constitution was constructed in the Charlestown Navy Yard in 1797. The Charlestown yard is now the Edmond Hartt Shipyard.
In December 1941, work was started on a graving dock, 693 feet long, 91 feet wide at entrance, and 32 feet deep over the blocks, for the repair of cruisers. This dock, which was built inside a cellular steel pile cofferdam, was completed and placed in service in March 1943. The cofferdam was later incorporated as part of Piers 5 and 6. Work was also undertaken in 1941 on a 500-man barracks for ship's crews, necessitated by the fact that with three-shift repair work, the crews could not be quartered aboard. The expansion of the Annex continued with the construction of an additional 900-foot pier, started in the fall of 1942, a rigger's shop, a paint shop, and a general shop, started in November of that year, and extensive improvements and additions to utilities, streets, tracks, and equipment.   From: History.Navy
