History

Developed by Supermarine as an updated replacement for the Walrus, the Sea Otter first flew in 1938 but did not enter service until 1944 due to production priorities. It served primarily in the air-sea rescue role, picking up downed aircrew, and also conducted anti-submarine patrols. Around 290 were built and it served into the early postwar years.

Variants

The Sea Otter Mk I and Mk II were the main production versions, differing in equipment fit. The Mk II was equipped for the air-sea rescue role with additional rescue gear.

Where you'll see it

Operated by the Royal Navy Fleet Air Arm and RAF Coastal Command during the latter part of World War II and into the late 1940s. It served in European and Far Eastern theatres. The type was retired from UK service by around 1952.
