American Patrol Craft-Building Program in World War II: January 1, 1942–July 1, 1942

JANUARY 1, 1942 - JULY 1, 1942

The United States Maritime Commission built 417 patrol craft in World War II. These consisted of 354 173-foot PCs and sixty-three 180-foot PCEs. The Americans transferred forty-four PCs to other navies and fifteen PCEs to the Royal Navy, which designated the ships Kil class. As shown below, thirty-one PCs were completed in the first half of 1942, but owing to delays in fitting out and workup and diversions to schools, on July 1, 1942, the Eastern Sea Frontier had only seven PCs available for convoy escort.
