Developed to work alongside the very successful Shorts Sunderland flying boat, the smaller twin-engine Saro Lerwick also entered service with the RAF in 1938. Unfortunately the initial service trials revealed various deficiencies with the design; the Lerwick proved to have serious stability problems both in the air and on the water. However, wartime necessity saw the type introduced into service regardless of the deficiencies. Attempts to resolve the problems did not prove entirely successful. Consequently, the type was quickly relegated to operational training duties and by 1941 was eventually withdrawn from service when suitable quantities of the more successful Sunderland aircraft were available.
Although no Lerwick aircraft were officially on strength with the RCAF, in fact, two RCAF squadrons, Nos. 422 and 423, were initially equipped with Lerwick Mk I aircraft for operational training purposes before transitioning to the Sunderland aircraft type.
