101 years ago today, the act authorizing construction of submarine chasers was passed. Construction projects were spread out among small and large shipbuilders, nationwide. Of the 441 submarine chasers built, 403 were completed and launched during the war. Of these, 100 were built for France. Of the 303 boats in the U.S. Navy, 133 were sent overseas to engage in antisubmarine warfare, and were stationed primarily at three bases: Plymouth, Corfu, and Queenstown (Cobh).
See the Appendices of Hunters of the Steel Sharks for a complete listing of the chasers that served from these bases.
