The Aero A.11 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia between the First and Second World Wars. It formed the basis for many other Czechoslovakian military aircraft of the inter-war period. Around 250 were built, with some remaining in service at the outbreak of World War II.

The Avro Anson is a British twin-engined, multi-role aircraft built by the aircraft manufacturer Avro. Large numbers of the type served in a variety of roles for the Royal Air Force (RAF), Fleet Air Arm (FAA), Royal Canadian Air Force (RCAF) and numerous other air forces before, during, and after the Second World War.

The Beriev MBR-2 was a Soviet multi-purpose flying boat which entered service with the Soviet Navy in 1935. Out of 1,365 built, 9 were used by foreign countries including Finland and North Korea. In Soviet Union it sometimes carried the nickname of "Kорова" (cow) and "Амбар" (barn).

The Blackburn T.5 Ripon was a British carrier-based torpedo bomber and reconnaissance biplane which first flew in 1926. It was used by the Fleet Air Arm as a torpedo bomber from 1930 until 1935. Ripons were also sold to Finland, where they continued to be used in action in the Winter War and the Continuation War until 1944.

The Brewster F2A Buffalo is an American fighter aircraft which saw service early in World War II. Designed and built by the Brewster Aeronautical Corporation, it was one of the first U.S. monoplanes with an arrestor hook and other modifications for aircraft carriers. The Buffalo won a competition against the Grumman F4F Wildcat in 1939 to become the U.S. Navy's first monoplane fighter aircraft. Although superior to the Grumman F3F biplane it replaced, and the early F4Fs, the Buffalo was largely obsolete when the United States entered the war, being unstable and overweight, especially when compared to the Japanese Mitsubishi A6M Zero.

The Bristol Blenheim is a British light bomber aircraft designed and built by the Bristol Aeroplane Company (Bristol) which was used extensively in the first two years and in some cases throughout the Second World War. The aircraft was developed as Type 142, a civil airliner, in response to a challenge from Lord Rothermere to produce the fastest commercial aircraft in Europe. The Type 142 first flew in April 1935, and the Air Ministry, impressed by its performance, ordered a modified design as the Type 142M for the Royal Air Force (RAF) as a bomber. Deliveries of the newly named Blenheim to RAF squadrons commenced on 10 March 1937.

The C.710 were a series of light fighter aircraft developed by Caudron-Renault for the French Air Force just prior to the start of World War II. One version, the C.714, saw limited production, and were assigned to Polish pilots flying in France after the fall of Poland in 1939. A small number was also supplied to Finland.

The Curtiss P-36 Hawk, also known as the Curtiss Hawk Model 75, is an American-designed and built fighter aircraft of the 1930s and 40s. A contemporary of both the Hawker Hurricane and Messerschmitt Bf 109, it was one of the first of a new generation of combat aircraft—a sleek monoplane design making extensive use of metal in its construction and powered by a powerful radial engine.

The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facilities at Buffalo, New York.

The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and many other operators as a primary trainer aircraft. In addition to the type's principal use for ab-initio training, the Second World War saw RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers.

The Dornier Do 17, is a twin-engined light bomber produced by Dornier Flugzeugwerke for the German Luftwaffe during World War II. Designed in the early 1930s as a Schnellbomber intended to be fast enough to outrun opposing aircraft, the lightly built craft had a twin tail and "shoulder wing". Sometimes referred to as the Fliegender Bleistift, it was popular among its crews due to its handling, especially at low altitude, which made the Do 17 harder to hit than other German bombers.

The Dornier Do 22 was a German seaplane, developed in the 1930s. Despite good performance, it was built only in small numbers and entirely for the export market. The type was operated in the Second World War by Greece, Yugoslavia and Finland.

The Douglas C-47 Skytrain or Dakota is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remained in front-line service with various military operators for many years.

The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Corporation starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.

The Fiat G.50 Freccia ("Arrow") was a World War II Italian fighter aircraft developed and manufactured by aviation company Fiat. Upon entering service, the type became Italy’s first single-seat, all-metal monoplane that had an enclosed cockpit and retractable undercarriage. On 26 February 1937, the G.50 conducted its maiden flight. During early 1938, the Freccias served in the Regia Aeronautica and with its expeditionary arm, the Aviazione Legionaria, in Spain, where they compared well in speed and manoeuvrabilty with their adversaries in the theatre.

The Fieseler Fi 156 Storch was a small German liaison aircraft built by Fieseler before and during World War II. Production continued in other countries into the 1950s for the private market. It was notable for its excellent STOL performance and low stall speed of 50 km/h. French-built later variants often appear at air shows.

The Fokker D.XXI fighter was designed in 1935 by Dutch aircraft manufacturer Fokker in response to requirements laid out by the Royal Netherlands East Indies Army Air Force.

The Gloster Gladiator is a British-built biplane fighter. It was used by the Royal Air Force (RAF) and the Fleet Air Arm (FAA) and was exported to a number of other air forces during the late 1930s.

The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–40s that was designed and predominantly built by Hawker Aircraft Ltd. for service with the Royal Air Force (RAF). It was overshadowed in the public consciousness by the Supermarine Spitfire's role during the Battle of Britain in 1940, but the Hurricane inflicted 60 percent of the losses sustained by the Luftwaffe in the engagement, and fought in all the major theatres of the Second World War.

The Heinkel He 59 was a twin-engined German biplane designed in 1930, resulting from a requirement for a torpedo bomber and reconnaissance aircraft able to operate on wheeled landing gear or twin-floats.

The Heinkel He 115 was a three-seat World War II Luftwaffe seaplane. It was used as a torpedo bomber and performed general seaplane duties, such as reconnaissance and minelaying. The aircraft was powered by two 960 PS BMW 132K nine-cylinder air-cooled radial engines. Some later models could seat four, had different engines or used different weapon arrangements.

The Junkers Ju 52/3m is a transport aircraft that was designed and manufactured by German aviation company Junkers.

The Junkers Ju 88 is a German World War II Luftwaffe twin-engined multirole combat aircraft. Junkers Aircraft and Motor Works (JFM) designed the plane in the mid-1930s as a so-called Schnellbomber that would be too fast for fighters of its era to intercept. It suffered from technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other Luftwaffe bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb.

The Lavochkin-Gorbunov-Gudkov LaGG-3 was a Soviet fighter aircraft of World War II. It was a refinement of the earlier LaGG-1 and was one of the most modern aircraft available to the Soviet Air Force at the time of Germany's invasion in 1941. Despite its wooden construction, it was both overweight and underpowered. At one point in the war, on average 12 LaGG-3s were being completed daily and 6,528 had been built in total when Factory 31 in Tbilisi switched production to the Yak-3 in 1944.

The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190, the backbone of the Luftwaffe's fighter force. The Bf 109 first saw operational service in 1937 during the Spanish Civil War and was still in service at the dawn of the jet age at the end of World War II in 1945. It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine. It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation.

The Morane-Saulnier M.S.406 is a French fighter aircraft developed and manufactured by Morane-Saulnier starting in 1938. It was France's most numerous fighter during the Second World War and one of only two French designs to exceed 1,000 in number. At the beginning of the war, it was one of only two French-built aircraft capable of 400 km/h (250 mph) – the other being the Potez 630.

The Petlyakov Pe-2 was a Soviet twin-engine dive bomber used during World War II. One of the outstanding tactical attack aircraft of the war, it also proved successful as a heavy fighter, as a night fighter and as a reconnaissance aircraft. In many respects it resembled the wooden British de Havilland Mosquito. The Pe-2 was, numerically, the most important Soviet bomber of World War II, at their peak comprising 75% of the Soviet twin-engine bomber force. The Soviets manufactured Pe-2s in greater numbers during the war than any other twin-engine combat aircraft except for the German Junkers Ju 88 and the British Vickers Wellington. Several Communist air forces flew the type after the war, when it became known by the NATO reporting name Buck.

The Petlyakov Pe-3 was the long-range heavy fighter version of the successful Petlyakov Pe-2 high-speed dive bomber used by the Soviet Union during World War II.

The Polikarpov I-15 was a Soviet biplane fighter aircraft of the 1930s. Nicknamed Chaika because of its gulled upper wings, it was operated in large numbers by the Soviet Air Force, and together with the Polikarpov I-16 monoplane, was one of the standard fighters of the Spanish Republicans during the Spanish Civil War, where it was called Chato (snub-nose).

The Polikarpov Po-2 served as an all-weather multirole Soviet biplane, nicknamed Kukuruznik, NATO reporting name "Mule". The reliable, uncomplicated concept of the Po-2's design made it an ideal trainer aircraft, as well as doubling as a low-cost ground attack, aerial reconnaissance, psychological warfare and liaison aircraft during war, proving to be one of the most versatile light combat types to be built in the Soviet Union. As of 1978 it remained in production for a longer period of time than any other Soviet-era aircraft.

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 Tupolev ANT-40, also known by its service name Tupolev SB and development co-name TsAGI-40, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934. The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation".
The VL Humu is a Finnish fighter aircraft, designed by Valtion lentokonetehdas in 1944, and based on the American Brewster F2A Buffalo.

The VL Myrsky is a Finnish World War II fighter aircraft originally developed by Valtion lentokonetehdas for the Finnish Air Force. The models of the aircraft were Myrsky I, Myrsky II, and Myrsky III.
