The Fairey Firefly IIM was a British fighter of the 1930s. It was a single-seat, single-engine

Belgian Air Force throughout the 1930s until the outbreak of World War II
.

Design and development

The Firefly was a private-venture design, penned by

Specification F.20/27 for a single-seat interceptor. It first flew on 5 February 1929.[1]

The Firefly II competed for the

RAF contract against the Hawker Fury, showing superior speed but was criticised for having heavier controls.[1]
Crucially, it retained a mainly wooden structure despite the Air Ministry's demands for metal structures. This led to the Fury being selected. Afterwards, the prototype was rebuilt and renamed Firefly IIM, the "M" denoting the all-metal construction of the rebuilt machine.

A revised prototype with longer-span wings, the Firefly III was built to

trainer by the RAF's High Speed Flight preparing for the 1931 Schneider Trophy race.[4]

Operational history

A contract was won for 25 IIM aircraft for Belgium's

Aviation Militaire, followed by a contract for a further 62 to be constructed by Avions Fairey, Fairey's Belgian subsidiary. The Belgian aircraft served briefly in the Second World War
from May to June 1940.

Two of the Belgian aircraft were converted to Firefly IV, with 785 hp (585 kW) Hispano-Suiza 12Xbrs engines but the improvement was not deemed sufficient to warrant development. One was restored to its original form, while the other passed to Fairey for trials. One aircraft was supplied to the Soviet Union.
