HMS Virulent was a V-class submarine of the Royal Navy. She was built during the Second World War as part of the second batch (18 in number) of V-class submarines ordered on 21 May 1942.

Vickers-Armstrongs built her at High Walker, Newcastle upon Tyne. She was laid down on 30 March 1943, launched on 23 May 1944, and commissioned on 1 October 1944.

Fate

Virulent was lent to the Hellenic Navy as Argonaftis (U15) from 29 May 1946 until 3 October 1958. She was intended to be towed from Malta to the River Tyne. She broke adrift from the tow on 15 December 1958 and became stranded on the northern Spanish coast. She was then found and towed by two Spanish trawlers, the frigate Hernán Cortés and the patrol boat V-18 to Pasajes on 6 January 1959.^[1] Sold to a Spanish scrap company in spring 1961, she was eventually scrapped in April 1961 at Pasajes.^[2]
