Fascinating World War 2 Fighters from Unexpected Countries

While iconic World War II fighters mostly hailed from major powers like the United States and Germany, smaller nations also produced their own combat aircraft, often out of necessity when global supplies ran thin. Surprisingly, some of these lesser-known planes performed impressively in combat. Heres a look at ten fascinating fighters from nations you might not immediately associate with advanced wartime aviation, ranging from Australia to Yugoslavia.

10: CAC Boomerang

Following the attack on Pearl Harbor, Australia faced the threat of Japanese aggression and a fragile supply chain for modern aircraft. To ensure local defense, Lawrence Wackett of the Commonwealth Aircraft Corporation proposed a home-built fighter. The Boomerang, derived from the Wirraway trainer and powered by the Pratt & Whitney R-1830 Twin Wasp engine, first flew in May 1942. Though manoeuvrable, the aircraft was slow and initially struggled to intercept Japanese bombers. Once reassigned to close-support missions, it excelled in the South West Pacifics small-scale, intense combat conditions.

9: Avia B.534

Czechoslovakias B.534, one of the finest combat biplanes, entered service in 1933. Even after Germany annexed Czechoslovakia in 1939, the aircraft continued to serve multiple nations. Variants included the Bk.534 with a 20mm cannon and later models with bubble canopies for improved visibility. B.534s flew on the Eastern Front and in uprisings, scoring limited victories, including the last recorded air-to-air kill by a biplane. Germany, Bulgaria, Greece, and Yugoslavia also used the aircraft in various roles.

8: VL Myrsky

Finland developed the Myrsky (Storm) in 1939 due to potential shortages of imported fighters. Like the Boomerang, it used the Pratt & Whitney R-1830 engine, obtained via Germany. Constructed mainly of wood, it was fast and agile, proving effective against Soviet aircraft during the Continuation War. However, poor-quality glue caused structural failures in harsh weather. Despite this, the Myrsky remained in service until 1948.

7: Fokker D.XXI

The Dutch Fokker D.XXI was a rugged low-wing monoplane with a fixed undercarriage, designed for the Netherlands East Indies but primarily used in Europe. Finland adopted it during the Winter War, achieving 130 victories for 12 losses. Dutch D.XXIs also performed well against the Bf 109E during the 1940 German invasion, claiming 16 confirmed kills.

6: Fokker G.1

The Fokker G.1 was a heavy twin-boom fighter developed privately in the Netherlands. Noted for its eight forward-firing machine guns, it inspired designs like the Lockheed P-38 Lightning. Only 36 were ordered, and 23 were available during Germanys 1940 invasion. Surviving aircraft mainly conducted ground-attack missions, securing 14 aerial victories before being used as trainers by the Germans. Two escaped to England in 1941.

5: PZL P.24 / IAR 80

The Polish PZL P.24 was a gull-winged fighter exported to Bulgaria, Greece, Romania, and Turkey but not used by Poland itself. Greek P.24s fought effectively against Italian biplanes, while Romanian units defended key locations against Soviet forces. Romania also used the P.24 design as the foundation for the improved IAR 80, which saw combat against Soviet aircraft and later defended against U.S. bombing raids before being replaced by Bf 109Gs in 1944.

4: FFVS J 22

Swedens FFVS J 22, nicknamed a pocket rocket, was developed after a U.S. arms embargo blocked modern fighter imports. Built with the R-1830 engine, the lightweight aircraft offered excellent performance and was competitive with P-51Ds up to 20,000 ft. Pilots praised its handling, and it served in Swedish front-line units until 1952, with 198 aircraft produced.

3: Saab J 21

The Swedish SAAB 21 featured a pusher layout, placing the propeller behind the cockpit, and was one of the first fighters to include an ejection seat. First flown in 1943, it was built for heavy forward armament and excelled in fighter-bomber roles. Powered by a Daimler-Benz DB 605 engine, it was later redesigned for jet propulsion, becoming the J 21R and Swedens first military jet in 1950.

2: Rogoarski IK-3

Yugoslavias Rogoarski IK-3 was a domestic fighter that saw action during the Axis invasion in April 1941. Advanced for its time, it featured a retractable undercarriage and outperformed many German aircraft in manoeuvrability. Only 12 were completed, but they achieved notable success, including 11 enemy kills during eleven days of combat. A re-engined version later formed the basis of the Ikarus S-49, used until 1961.
