The Gloster Grebe was developed from the Gloster Grouse (an experimental aircraft later developed as a trainer), and was the Royal Air Force's first post First World War fighter aircraft, entering service in 1923.

Design

In 1923 Gloster produced two Gloster Grouse research aircraft / advanced trainer. Air Ministry officials ordered three prototypes of a Jaguar III engined fighter derivative, which entered production with the Jaguar IV engine as the Grebe IV.

The Grebe retained the same single seat biplane layout, fabric-covered wooden structure and twin Vickers machine gun armament as the Sopwith Snipes it replaced, the only real advance - a 162 mph (261 km/h) top speed - coming from the extra power of the 400 hp Armstrong Siddeley Jaguar, (a prepared Grebe claimed a British record with a speed of 212.2 miles per hour).

Service history

Grebes entered service with No. 111 Squadron RAF during October 1923. The service found the Grebe to be very agile, but it suffered from wing flutter, which led to all RAF aircraft being modified with additional wing struts.

A total of 133 Grebes were produced, including dual-control trainers. All but 4 were Mark IIs. Grebes were retired from the RAF in 1929, replaced in part by the Gloster Gamecock which was in essence a developed Grebe, (Gloster fighter design, from Nighthawk to Gloster Gladiator was essentially evolutionary).

Two Grebes were modified for suspension beneath the R33 Airship on a 'trapeze' for "parasite" trials.

The Grebe was developed into the Gloster Gamecock fighter, which also entered production for the RAF.

A single Grebe was gifted to New Zealand by Sir Henry Wigram, and subsequently another two Grebes were acquired by the New Zealand Permanent Air Force, fore-runner of the Royal New Zealand Air Force, entering service in March 1928 and serving more than 10 years until the mid-1938. The two survivors were used as instructional airframes until destroyed in 1943/44.
