HMS Relentless (H85)
The R-class destroyer HMS Relentless (H85) was commissioned on 30 November, 1942. She served on anti-submarine patrols in the South Atlantic and Indian Oceans during World War II, and was placed in reserve in 1946. In 1949, work was begun to convert Relentless to a Type 15 Anti-Submarine frigate. Work completed in 1951, and she recommissioned with pennant number F 185. Relentless participated in Queen Elizabeth's coronation fleet review, and she suffered a serious collision with HMS Vigilant in 1954. After repairs, she briefly resumed service, before returning to reserve in 1956. Relentless recommissioned from June, 1964, to August, 1965, to replace HMS Diana in the 29th Escort Squadron. She was placed on the disposal list that August, but was not sold for scrap until 1971.
