USCGC Castle Rock

USCGC Castle Rock (WAVP-383, later WHEC-383) was a Casco-class high endurance cutter of the United States Coast Guard, commissioned in 1944. Initially serving as a patrol frigate during World War II, Castle Rock performed anti-submarine and escort duties in the Atlantic. During the Cold War, she was reclassified and assigned to ocean station duty, weather reporting, and search and rescue missions. In 1971, the cutter was transferred to the South Vietnamese Navy as RVNS Trần Bình Trọng (HQ-05), and later served in the Philippine Navy after the fall of South Vietnam.
