Formed 15 Oct 1941 at RAF Valley as an Air-Sea Rescue unit with Walrus and Lysander fixed wing aircraft, it was disbanded at Harrowbeer, north of Plymouth on 15 Feb 1945. It reformed on 1 Mar 1953 at RAF Linton-on-Ouse, to become the first RAF SARÂ squadron to use the helicopter, with the Sycamore HR.13 in Apr 1953. It was also one of the few RAF units to use the Hiller HTE-2 (between Feb 1954 and May 1955), most being in Royal Navy service. In Jul 1954 the Sycamore HR.14 was introduced and this served until the unit was finally disbanded.
Squadron strength had built to 15 Sycamore in 6 Flights by 1957, including F Flt, which formed at Aldergrove on 15 Jul 1957 with 3 Sycamore. Following a unit re-organisation, F Flt became B Flt in Jun 1958. B Flt left Aldergrove on 4 Apr 1959.
In Mar 1959, the Whirlwind HAR.4 arrived, followed by some Whirlwind HAR.2s in Aug 1959. On 1 Sep 1959, the unit disappeared, being renumbered as 228 Squadron.
