context_page_description: USS Castle Rock (AVP-35) was a United States Navy Barnegat-class small seaplane tender in commission from 1944 to 1946 which saw service in the late months of World War II. After the war, she was in commission in the United States Coast Guard as the Coast Guard cutter USCGC Castle Rock, later WHEC-383, from 1948 to 1971, seeing service in the Vietnam War during her Coast Guard career. Transferred to South Vietnam in 1971, she served in the Republic of Vietnam Navy as the frigate RVNS Trần Bình Trọng and fought in the Battle of the Paracel Islands in 1974. When South Vietnam collapsed at the end of the Vietnam War in 1975, Trần Bình Trọng fled to the Philippines, where she served in the Philippine Navy from 1979 to 1985 as the frigate RPS Francisco Dagohoy.
context_section_description: Barnegat-class ships were very reliable and seaworthy and had good habitability, and the Coast Guard viewed them as ideal for ocean station duty, in which they would perform weather reporting and search and rescue tasks, once they were modified by having a balloon shelter added aft and having oceanographic equipment, an oceanographic winch, and a hydrographic winch installed. After World War II, the U.S. Navy transferred 18 of the ships to the Coast Guard, in which they were known as the Casco-class cutters.
  The U.S. Navy loaned Castle Rock to the Coast Guard on 16 September 1948. After undergoing conversion for use as a weather-reporting ship, she was commissioned into Coast Guard service as USCGC Castle Rock (WAVP-383) on 18 December 1948 at Mare Island Navy Yard, Vallejo, California.
