HMS Lark was a modified Black Swan-class sloop of the Royal Navy, constructed by Scotts Shipbuilding and Engineering Company in Greenock. She was laid down on 5 May 1942, launched on 28 August 1943, and commissioned on 10 April 1944, bearing the pennant number U11. As a Black Swan-class vessel, she featured the typical design of this class, optimized for escort and anti-submarine duties during World War II. After her commissioning, HMS Lark completed her preparations in Tobermory and was deployed to convoy defense duties for Western Command. During May and June 1944, she played a role in the Allied invasion of Normandy, serving as part of the 114th Escort Group alongside ships such as HMS Crane, HMS Blankney, HMS Chelmer, and HMS Torrington, escorting assault convoys during Operation Neptune. Following the Normandy landings, HMS Lark was assigned to Arctic convoy duties, protecting supply routes to the Soviet Union in the Kola Bay area. Her service in these treacherous waters included participation in convoy operations JW 61 to JW 64 and RA 61 to RA 64, crucial for maintaining Allied support to the Eastern Front. A notable event in her service occurred on 17 February 1945, when she engaged a German U-boat. HMS Lark, in conjunction with HMS Alnwick Castle, sank U-425 in the Barents Sea east of the Rybatchy Peninsula using depth charges. Later that day, she was herself damaged when U-968 fired an acoustic torpedo at convoy RA 64, hitting HMS Lark aft northeast of Murmansk. The vessel was subsequently towed into Kola Bay and grounded near Rosta, unable to return to the UK. By June 1945, her wreck, stripped of most equipment, was handed over to the Soviet Navy. Postwar reports suggest she may have been renamed Neptun in Soviet service, but this remains unconfirmed. It is unlikely that her hull was rebuilt for further use, marking her as a significant wartime escort vessel with notable contributions to Arctic convoy operations and anti-submarine warfare.
