She was launched by Mrs Phillips on 28th August 1943 and was the 15th RN warship to carry the name introduced in 1656 for a Royalist Prize. It had last been used by for a 1913 destroyer sold in 1923. After a successful WARSHIP WEEK National Savings campaign in March 1942 this Sloop was adopted by tine civil community of Billericay, Essex. Build completion date was 10th April 1944 and her radar outfits included the new design Type 276 which replaced the first centimetric design (Type 272) fitted in the earlier ships of this Class. The other radars, Type 285 for fire control and Type 291 to provide warning of aircraft and surface targets were the same as fitted in other ships of this type (See RADAR AT SEA by D Howse).

Special  Note


HMS LARK was de-equipped at Rosta where she lay, as return to UK under tow was not feasible. In June 1945 the hulk with most equipment removed was handed to the Soviet Navy. Post war reports suggested that she may have later  been taken into Russian naval service under the name NEPTUN but this has not be substantiated. It is unlikely that the hull would have been rebuilt and re-equipped to allow further use.
