The Supermarine Spiteful was a further development of the Supermarine Spitfire. Designed to give the plane improved manouverability at higher speeds, and also make it significantly faster. While it never entered active service with the RAF, it did enter serial production and went on to be used as a testbed for early jet technologies. The aircraft is one of the very last piston fighters ever designed.



Work on the Supermarine Spiteful began internally in Supermarine on 30 November 1942 with specification 470, this called for a spitfire with a laminar flow wing that would increase top speed and high speed manouverability.

The air ministry showed interest in the concept and issued specification F.1/43 in Feburary 1943 to further develop the concept.
The first prototype (NN660) was a Spitfire mk XIV fitted with the new wing, this prototype flew 30th June 1944 and later crashed.
During development it was discovered that that airframe suffered from instability and therefore needed larger fins, rudders and tailplane. This “Spiteful type tailplane” would go on to be used on the Spitfire mk22 and mk24.

The air ministry ordered 150 aircraft, and the first production Spiteful (RB515) flew in April 1945. But with the success of jet aircraft the order was eventually limited to just 2 more flying prototypes and 17 production aircraft.

Although the type never entered operational service with the RAF it was used as a testbed for development of early jet technologies. In the end it was determined that the new type of wing would be suitable for a new jet aircraft, later named ‘Supermarine Attacker’

The current Mk 24 is a good bit over-tiered at 7.0, but this? This is likely worth that position.
+1 absolutely. I’d love to see Britain as the kings of prop planes again.

Absolutely yes, we really need some REAL NEW props at the moment

+1, would be a great addition

Along with its sibling, the Seafang, this aircraft should have been implemented years ago!
