History

Developed from the Sidestrand, the Overstrand introduced an enclosed, heated cockpit and a hydraulically powered nose turret — revolutionary features for the time. It entered service with No. 101 Squadron in 1935, giving the RAF its first taste of powered defensive armament. The type was soon rendered obsolete by monoplane bombers and retired by 1938.

Variants

The Overstrand was a direct development of the Sidestrand Mk III, the primary change being the enclosed powered turret and refined airframe; no major sub-variants entered production.

Where you'll see it

Served exclusively with No. 101 Squadron, RAF Bicester, from 1935 to 1938, making it a uniquely British interwar aircraft.
