The author’s three-dimensional impression of the Bristol Aquila-powered twin-tailed Gloster F.34/35. It is shown bearing the RAF serial K8625, which was allocated to the type before development work on the design was cancelled when the Boulton Paul Defiant was built to Specification F.9/35, which covered the requirements of both.

Folland's design to Specification F.34/35 for a twin-engined two-seat fighter with a four-gun power-operated dorsal turret and nose armament, as tendered in 1936. Single-finned and twin-finned configurations were drawn up, but again Folland’s hopes were dashed when the project was abandoned.
