Saab 21R
The Saab 21R was a Swedish twin-boom fighter/attack aircraft, made by SAAB. It was a jet-powered development of the piston-engined Saab 21 and is unusual for being the only aircraft that saw service as both a piston-engined fighter, and a jet fighter. As a fighter, its service designation in the Swedish Air Force was J 21R, and saw service in the late 1940s.

Design and development
The 21R was powered by a De Havilland Goblin 3 turbojet and was Sweden's first jet-powered aircraft to be developed and built domestically.
There were quite a few differences between the 21A and the 21R, aside from the method of propulsion. The most notable difference was that the tailplane was raised to the top of the fins, moving it out of the way of the jet blast.
Operational history
The first prototype Saab 21R first flew on 10 March 1947, just after the Second World War. The aircraft first entered into service with F 10 in August 1950. Although the type was originally intended as a fighter aircraft, a newly developed fighter, the Saab J 29 first flew in October 1948, the number to be produced was halved from 120 to 60, and eventually all 21Rs were converted to attack aircraft as A 21RA or the A 21RB depending on the engine type.
