History

The Supermarine Sea Otter was a biplane amphibian for reconaissance and 'Search and Rescue' duties. The forst two prototypes ordered under Contract No 493798/36 to specification  5/36 from Supermarine were given the original name for the Sea Otter which was due to be called the Stingray. The first prototype K8854 carried out its first flight on 29 September 1938 ansd subsequently was involved in various recovery trials with HMS Pegasus in February and November 1939. The second prototype K8855 was destroyed in an air raid on Woolston on the 26 September 1940 at the height of the Battle of Britain.

The first prototype was sent to C squadron A& AEE, Boscombe Down for w/e in December 1941 and subsequently to Admiralty charge and became the first Sea Otter to enter squadron service with 763 squadron at Sandbanks in June 1943.


RAN Sea Otter at the end of WWII

The Sea Otter was broadly based on the Walrus, with a tractor engine and more refined construction. It could be either Carrier or shore based and served with the RAF Coastal Command and the FAA. It consisted of two marks, Mk I Amphibian with optional underwing bombs or depth charges and the A.S.R. Mk II Air/Sea rescue version.

Following the success of the prototypes, 250 production Sea Otter ABR.I were ordered under Contract No Ctts/Acft/1806 from Saunders-Roe Ltd, Cowes and the final aircraft being completed as ASR.II from JN185-JN257.

The first production aircraft was delivered in August 1943, and a total of 4 had been delivered by the end of the year, the rest been delivered in 1944 and 1945. The Sea Otter was the last biplane to enter RAF and FAA service in 1944. A total of 292 were built mainly for the FAA although only 94 had been delivered by August 1945.
