USS Castle Rock (AVP-35)

USS Castle Rock (AVP-35) was a United States Navy Barnegat-class small seaplane tender in commission from 1944 to 1946.

Construction and commissioning
Castle Rock was laid down on 12 July 1943 at Houghton, Washington, by the Lake Washington Shipyard, and was launched on 11 March 1944, sponsored by Mrs. R. W. Cooper. She commissioned on 8 October 1944 with Commander G. S. James, Jr., in command.

World War II
Castle Rock stood out of San Diego, California, on 18 December 1944 bound for Pearl Harbor, Hawaii, and Eniwetok, where she arrived on 28 January 1945. Assigned to escort convoys between Saipan, Guam, and Ulithi Atoll until 20 March 1945, Castle Rock then took up duties of tending seaplanes at Saipan. Her seaplanes carried out varied air operations, including reconnaissance, search, and hunter-killer activities, while Castle Rock herself also performed local escort duties.

Post-World War II
On 28 November 1945, Castle Rock sailed from Saipan for Guam, where she embarked a group assigned to study Japanese defenses on Chichi Jima and Truk. This continued until 5 January 1946, when Castle Rock returned to seaplane tender operations at Saipan.

Castle Rock left Saipan on 9 March 1946, arriving at San Francisco, California, on 27 March 1946. She was decommissioned there on 6 August 1946

On 16 September 1948, Castle Rock was loaned to the United States Coast Guard, which commissioned her on 18 December 1948 as the cutter USCGC Castle Rock (WAVP-383), later being reclassified as a high endurance cutter and redesinated WHEC-383. While in Coast Guard service, her primary duty was to patrol ocean stations, reporting weather data and engaging in search-and-rescue and law-enforcement operations. She also performed combat duty in the Vietnam War for a few months in 1971. The Coast Guard decommissioned her on 21 December 1971.

South Vietnamese service
On 21 December 1971, Castle Rock was transferred to South Vietnam, which commissioned her as patrol vessel RVNS Tran Binh Trong (HQ-05). In January 1974, Tran Binh Trong was part of a South Vietnamese that fought in the Paracel Islands against ships of the People's Republic of China in the Battle of the Paracel Islands.

When the South Vietnamese government collapsed at the end of the Vietnam War in 1975, Tran Binh Trong fled to the Philippines.
