The SC-497-class submarine chasers were a class of 438 submarine chasers built primarily for the United States Navy from 1941–1944.^[1] The SC-497s were based on the experimental submarine chaser, USS SC-453. Submarine chasers of this variety were collectively nicknamed "the splinter fleet" due to their wooden hulls.^[2]
