Supermarine Type 224

Supermarine · United Kingdom · first flew 1934 · fighter

The Supermarine Type 224 was a 1934 British fighter prototype that lost the RAF's F.7/30 competition, but it is historically significant as the direct predecessor design from which R.J. Mitchell developed the Spitfire. Its poor performance relative to expectations spurred Mitchell to produce the far superior Type 300.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

A low-wing monoplane with a distinctive inverted gull or cranked wing to accommodate the fixed undercarriage, an open cockpit, and an unusually large wing area required by the evaporative cooling system; the overall appearance is ungainly compared to the elegant Spitfire that followed.

History

Designed by Reginald Mitchell to meet the Air Ministry's F.7/30 specification, the Type 224 featured an evaporative cooling system that required large surface condensers built into the wings, and a fixed gull-wing undercarriage. It proved underpowered and inferior to expectations, losing the competition to the Gloster Gladiator. Mitchell immediately began work on a private-venture replacement that became the Spitfire.

Variants

A single prototype was built; lessons from its failure directly influenced every aspect of the Spitfire's superior design.

Where you'll see it

Never entered operational service; the single prototype was used for testing and subsequently scrapped.
