HMS Fly (J306) was a reciprocating engine-powered Algerine-class minesweeper constructed during World War II. She was built by Lobnitz & Company in Renfrew, Scotland, with her keel laid on October 6, 1941, and launched on June 1, 1942. The vessel was commissioned into the Royal Navy on October 10, 1942. The ship measured 225 feet (68.6 meters) in overall length, with a beam of 35 feet 6 inches (10.8 meters) and a draught of 12 feet 3 inches (3.7 meters). Displacing between 1,010 and 1,030 long tons at standard load and up to 1,305 to 1,325 long tons at deep load, HMS Fly had a crew complement of 85 officers and ratings. Her propulsion system consisted of two vertical triple-expansion steam engines powered by two Admiralty three-drum boilers, generating 2,400 indicated horsepower, which allowed her to reach a maximum speed of 16.5 knots (30.6 km/h). She could carry up to 660 long tons (671 tons) of fuel oil, providing a range of 5,000 nautical miles (9,300 km) at a cruising speed of 10 knots. Armament on HMS Fly included a single QF 4-inch (102 mm) Mk V anti-aircraft gun and four twin-gun mounts for Oerlikon 20 mm cannons, although shortages often led to variations with single mounts. By 1944, some twin Oerlikon mounts were replaced with single Bofors 40 mm guns. The ship was also equipped with four throwers and two rails for depth charges, emphasizing her role in minesweeping and anti-submarine warfare. During her service in World War II, HMS Fly participated in exercises, notably anti-submarine drills off Tobermory in November 1942, alongside other Royal Navy submarines. Post-war, in 1946, she served as the flotilla leader for the 12th Minesweeper Flotilla, conducting mine clearance operations off the French and Dutch coasts. Decommissioned in February 1947, HMS Fly was placed in reserve before being sold to Iran on July 30, 1949. Renamed IIS Palang, she was reclassified as a frigate. She served with the Persian Navy until her decommissioning in 1966, was stricken from the naval register in 1972, and subsequently sold for scrap. The vessel's service highlights her role in minesweeping operations during and after WWII and her continued maritime significance through her transfer to Iran.
