The Mitsubishi A7MReppū was designed as the successor to the Imperial Japanese Navy's A6M Zero, with development beginning in 1942. Performance objectives were to achieve superior speed, climb, diving, and armament over the Zero, as well as better maneuverability – all parameters that were ultimately achieved towards the end of its development in 1945. However, limitations on Japanese industry towards the end of the war prevented the A7M from ever entering mass production or being deployed for active duty, and it never saw active service. Its Allied reporting name was "Sam".
The Saab 91 Safir is a three or four seater, single engine trainer aircraft. The Safir was built by Saab AB in Linköping, Sweden and by De Schelde in Dordrecht, Netherlands.
The Seversky XP-41 was a fighter aircraft built in the United States in 1939. A single prototype was modified from the last production Seversky P-35 by adding a new streamlined canopy, a Pratt & Whitney R-1830-19 engine with a two-speed supercharger, and revised landing gear. The XP-41 first flew in March 1939. The aircraft was developed in parallel with the P-43 Lancer, and work was stopped when the USAAC showed a preference for the latter.
The Saab 17 is a Swedish single-engine monoplane reconnaissance dive-bomber aircraft of the 1940s originally developed by ASJA prior to its merger into Saab. It was the first all-metal stressed skin aircraft developed in Sweden.
The Nakajima J5N was an abandoned Japanese prototype fighter aircraft of the World War II era. J5N was developed as twin-engine interceptor for countering attacks by Boeing B-29 Superfortress.
The Saab 210 is an approximately 70% scale research prototype for the double-delta configuration of the Saab 35 Draken supersonic fighter. It became known by the unofficial nickname Lilldraken. Its first flight was on 21 January 1952.
The Nakajima A6M2-N was a single-crew floatplane based on the Mitsubishi A6M Zero Model 11. The Allied reporting name for the aircraft was Rufe.
The Saab 18 was a twin-engine bomber and reconnaissance aircraft, designed and built by Svenska Aeroplan AB (SAAB) for use by the Swedish Air Force in response to a 1938 design competition. Due to delays, it did not enter service until 1944, but quickly became the standard Swedish bomber aircraft. Serving in the bomber, reconnaissance and ground-attack roles, it also assisted in the development of ejection seats and air-to-surface guided missiles until its replacement by the Saab Lansen in the late 1950s.
The Saab 21R was a Swedish fighter/attack aircraft developed and produced by Svenska Aeroplan AB (SAAB). It was a jet-powered development of the piston-engined SAAB 21 and was the first jet aircraft to be produced by Saab. The R-suffix stands for reaktion (reaction), referencing reaktionsdrift or reaktionsmotor. Along with the Soviet Yakovlev Yak-15, the 21R was one of only two jet fighters to have been successfully converted from piston-powered aircraft.
The SAAB 21 is a Swedish single-seat low-wing monoplane fighter and attack aircraft designed and manufactured by SAAB. Its twin boom fuselage with a pusher engine gave the aircraft an unusual appearance.

Raab-Katzenstein RK-26 Tigerschwalbe, also known as the Fieseler F 1 Tigerschwalbe, was a German twin-seat biplane trainer aircraft designed by Gerhard Fieseler by the end of the 1920s.
The Avro Type 584 Avocet was a British single-engined naval fighter prototype, designed and built by Avro. While the Avocet was not built in numbers, one of the prototypes was used as a seaplane trainer for the Royal Air Force's (RAF) High Speed Flight.
The PZL P.1 was a Polish fighter, designed by the engineer Zygmunt Puławski, manufactured by the PZL state-owned factory. It remained a prototype, but it was the first of the Polish PZL gull wing fighter series, leading to the PZL P.7, PZL P.11 and PZL P.24.
The Renard Epervier was a Belgian prototype single-seat all-metal fighter monoplane designed by Alfred Renard at the Societé Anonyme Avions et Moteurs Renard for a government-sponsored design contest in 1928. The Epervier Type 2 was built and flown in 1928, by Belgian aircraft manufacturer Stampe et Vertongen. It carried an armament of two synchronised 7.7mm guns and was lost in September 1928 after failing to recover from a flat spin. A second prototype, the Epervier Type 2bis, introduced revised streamlined fairings for the cantilever mainwheel legs, mainwheel spats and cylinder aft-fairings and was built by SABCA.
The Rikugun Ki-93 was a prototype Japanese twin-engined fighter aircraft of the Second World War. Designed by the Army Aerotechnical Research Institute, to be a heavy fighter armed with large calibre cannon to serve in the anti-shipping or bomber destroyer roles, only one example of the Ki-93 was completed; this was damaged on its maiden flight, and destroyed by American bombing before it could be flown again.
The PWS-11 was a Polish aerobatic and trainer aircraft, developed in 1928-1929 by PWS, which remained a prototype.
The Mitsubishi J4M Senden or Navy Experimental 17-Shi Otsu B Type Interceptor Fighter Senden, Allied reporting name Luke, was a Japanese World War II fighter aircraft proposed by Mitsubishi Heavy Industries for use by the Imperial Japanese Navy. The J4M project did not proceed beyond the design stage.
The MFI BA-12 Sländan is a single seat ultralight of pod and high boom configuration and with a butterfly tail. It was designed and built in Sweden in the 1980s and led to a two-seat, slightly larger, development called the BA-14.
The Heinkel HD 19 W was a biplane seaplane fighter developed by Ernst Heinkel Flugzeugwerke.
