Heinkel He 50

• Role: Biplane Bomber
• Manufacturing Nation: Germany
• Introduced: 1932
• Crew: 2
• Maximum speed: 235 km/h (146 mph)
• Range: 1,000 km (621 mi)
• Armaments: Machine guns for and aft
• Payload: Up to 500kg of bombs

The He 50 was a single-seat dive-bomber and two-seat reconnaissance biplane originally designed for the Imperial Japanese Navy. Serving in Luftwaffe pre-war dive-bombing units, the He 50 served almost until the end of World War II as a night harassment bomber. The He 50 was replaced by the Henschel Hs 123 and Junkers Ju 87, after which He 50s were transferred to dive bomber training units.

Caproni CA.73

• Role: Biplane Bomber
• Manufacturing Nation: Italy
• Introduced: 1924
• Crew: 2
• Maximum speed: 180 km/h (112 mph)
• Range: 540 km (336 mi)
• Armaments: Machine guns fore and aft
• Payload: Fuselage bomb racks

The Caproni Ca.73 was an Italian airliner produced during the 1920s which went on to serve as a light bomber in the newly-independent Regia Aeronautica. In the early 1920's, Italy's military planners still relied upon World War I-vintage Caproni Ca.3 bombers, and a replacement was soon sought. The immediate solution was to repurpose the Ca.73 as a warplane by adding a gunner's position in the nose, and dorsally and ventrally amidships. Ca.73s remained in frontline service until 1934, and from 1926 onwards participated in Italy's military actions in North Africa.

Hawker Hart

• Role: Biplane Bomber
• Manufacturing Nation: United Kingdom
• Introduced: 1930
• Crew: 2
• Maximum speed: 298 km/h (185 mph)
• Range: 692 km (430 mi)
• Armaments: Machine guns fore and aft
• Payload: to 235kg of bombs, attached to the wings

The Hawker light-bomber played a prominent role during the RAF's inter-war period. It spawned several variants, including a naval version. It was much faster than contemporary fighters, an astonishing achievement considering it was a light-bomber, and had high maneuverability, making the Hart one of the most effective biplane bombers ever produced for the Royal Air Force. It was also an effective dive-bomber, despite not being designed for that role.

Kawasaki Ki-3

• Role: Biplane Bomber
• Manufacturing Nation: Japan
• Introduced: 1933
• Crew: 2-3
• Maximum speed: 259 km/h (161 mph)
• Armaments: Machine guns fore and aft
• Payload: Up to 500kg of bombs

Developed from the KDA-6 reconnaissance prototype, the Kawasaki Ki-3 was designed by German engineer Richard Vogt, who later became chief designer for Blohm und Voss. It was a rugged aircraft, but the Ki-3's liquid-cooled engine was a constant source of trouble. The Ki-3 first saw service with the 6th Composite Air Regiment in Korea. It was the last biplane bomber design to be produced for the Imperial Japanese Army Air Force, and saw combat service in Manchukuo and in north China during the early stages of the Second Sino-Japanese War.

Breguet 19

• Role: Biplane Bomber
• Manufacturing Nation: France
• Introduced: 1924
• Crew: 2
• Maximum speed: 214 km/h (133 mph)
• Range: 800 km (500 mi)
• Armaments: Machine guns fore and aft, and one pointing straight down
• Payload: : Up to 472kg of bombs, either attached to the fuselage or in a downward-facing bomb bay

A trademark of the Breguet 19 was the wide usage of duralumin (precursor to aluminum) as a construction material, instead of steel or wood. At that time, the aircraft was faster than other bombers, and even some fighter aircraft. It came equipped with radio, while the recon version had a camera mounting. Due to these features it met with a huge interest in the world, and served in air forces in over 20 nations as either exports or local manufactures that made use of its design.

Keystone B-6

• Role: Biplane Bomber
• Manufacturing Nation: United States
• Introduced: 1921
• Crew: 5
• Maximum speed: 190 km/h (120 mph)
• Range: km (825 mi) Reduced to 363 mi when fully loaded.
• Armaments: Machine guns mounted on nose, dorsal and ventral
• Payload: Up to 1800kg of bombs

The B-6A together with B-5A were first line bombers of the United States for the period between 1930 and 1934. Well over 200 Keystone biplane bombers were built. Only 120 of them served in the continental USA, the remainder being deployed in Hawaii, the Philippines, and in the Canal Zone. Afterwards, they remained in service primarily as reconnaissance aircraft until the early 1940s. The B-6A served with the 20th, 49th and 96th Squadrons of the 2nd Bomb Group based at Langley Field, Virginia.

Polikarpov Po-2

• Role: Biplane Bomber
• Manufacturing Nation: USSR
• Introduced: 1929
• Crew: 2
• Maximum speed: 152 km/h (94 mph)
• Range: 630 km (391 mi)
• Armaments: Machine guns
• Payload: six 50kg bombs

The Po-2's low cost and easy maintenance led to a production run of over 40,000,. making it the most produced biplane in the history of aviation. Although a fairly ineffective bomber, its distinctive rattling sounds and attacks in the dead of night had a powerful psychological effect on already stressed-out German troops on the Eastern Front. It would make low level attacks on rear areas, denying the troops sleep and keeping them on guard from the "Sewing Machine" as they called it. It further demoralized them by using women pilots, nicknamed "Night Witches" by the Germans. The Po-2 was extremely hard to shoot down as its max cruising speed was comparable to the stall speed of the much faster German fighters and it typically flew at treetop level. It was also used as liaison, medevac and to supply Soviet partisans behind the front line.

Lublin R-VIII

• Role: Biplane Bomber
• Manufacturing Nation: Poland
• Introduced: 1929
• Crew: 2
• Maximum speed: 225 km/h (138 mph)
• Range: 600-1720 km (370-1061 mi)
• Armaments: Machine guns
• Payload: 1000 kg, in seaplane variant - 300 kg

Conventional wooden construction biplane, many were also fitted out as floatplanes and also came equipped with a camera. The R-VIII saw very little combat, since its performance suffered greatly when fully loaded with fuel and bombs. They were used for long range reconnaissance and had a large fuel bladder in the fuselage that could be dumped in the event of fire. After the invasion of Poland, they were evacuated to Hel Peninsula on Puck bay, where they bombed by Stukas.

Aero A.101

• Role: Biplane Bomber
• Manufacturing Nation: Czechoslovakia
• Introduced: 1930
• Crew: 2
• Maximum speed: 265 km/h (169 mph)
• Range: 845 km (562 mi)
• Armaments: Machine guns
• Payload: 500 kg (1,100 lb)

The Aero A.101 was a biplane light bomber and reconnaissance aircraft. The A.101 was an attempt to improve the Aero A.100 by enlarging it and fitting it with a more powerful engine. However, even with 33% more power, performance was actually inferior, and the Czech Air Force was not interested in the type. Production did result, however, when 50 were ordered by Spanish Republican forces for use in the Spanish Civil War. Some of these aircraft were captured by Nationalists while en route and used against their original buyers.

Fokker C.V

• Role: Biplane Bomber
• Manufacturing Nation: Netherlands
• Introduced: 1925
• Crew: 2
• Maximum speed: 215 km/h (132 mph)
• Range: 1,000 km (621 mi)
• Armaments: Machine guns
• Payload: Sixteen 8kg bombs

The C.V was the first multi-role aircraft and it was manufactured in a variety of versions; the customer could choose from five different wing constructions and engines. The landing gear could be changed from wheels to pontoons. The aircraft became an export success for Fokker, it was sold and/or license manufactured in Bolivia, China, Denmark, Finland, Hungary, Italy, Japan, the Netherlands, Norway, Switzerland, the Soviet Union, Sweden, and the US The Dutch Air Force used the C.V in front line service against the German Luftwaffe during World War II. After the Dutch surrender, the aircraft were taken over by Luftwaffe and used on the Eastern front until 1944.

IAR 37

• Role: Biplane Bomber
• Manufacturing Nation: Romania
• Introduced: 1937
• Crew: 1
• Maximum speed: 336 km/h (209 mph)
• Range: 1050 km (652 miles)
• Armaments: Machine guns
• Payload: 288kg (635lb) of bombs or 144 air-grenades

The IAR 37 was an unequal-span single bay biplane with room for a crew of three, dual controls, a locally designed bombsight and a camera. The aircraft entered service with the Royal Romanian Air Force in 1938 and by the end of the 1940 they equipped a large number of squadrons. When Romania supported the German offensive against the Soviet Union 15 of the 18 reconnaissance squadrons were equipped with IAR biplanes. The IAR 39 was used by most of the reconnaissance squadrons involved in the 1944 offensive against the Ukraine.
