The PC-461 class submarine chasers were a class of 343 submarine chasers built mainly for the US Navy built from 1941-1944. The PC-461s were based primarily on two experimental submarine chasers, the PC-451 and PC-452. While PC-461 began the series, the first of the class to enter service was the PC-471. As part of the Lend-Lease program, 46 ships of this class were transferred to allies of the United States. Fifty-nine PC-461s were converted to other types of patrol vessels. Eight vessels of this class were lost, and one vessel was lost after conversion to a PGM-9 class motor gunboat. Only one PC-461 actually sank a submarine during World War II.

One member of this class, the USS PC-1264, was one of only two ships in the Navy during World War II that had a mostly African-American crew.

Lend-Lease program[edit | edit source]

As part of the Lend-Lease program enacted by President Franklin D. Roosevelt, a total of 46 PC-461s were lent to allies of the United States. Thirty-two were sent to France, 8 to Brazil, 1 to Uruguay, 1 to Norway, 1 to the Netherlands, and 1 to Greece.

Post-WWII Importance[edit | edit source]

Following the end of World War II, many PC-461 class ships were placed into reserve squadrons or brought out of active service. Many more however were furnished to American allies around the world, most notably the Republic of Korea. The first vessel to join the new ROK Navy would be a PC-461 class ships that was transferred to Korean command in September 1949 as the ROKS Baekdusan, formerly the USS PC-823.

Conversions[edit | edit source]

Twenty-four PC-461s were converted to patrol gunboats, motor (PGM) and 35 were converted into amphibious control craft (PCC).
