The Tupolev ANT-40, also known by its service name Tupolev SB (Russian: Скоростной бомбардировщик - Skorostnoi Bombardirovschik - high speed bomber) 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'.

Numerically the most important bomber in the world in the late 1930s, the SB was the first modern stressed skin aircraft produced in quantity in the Soviet Union and probably the most formidable bomber of the mid-1930s. It was produced in the Soviet Union and was also built under license in Czechoslovakia. Many versions saw extensive action in Spain, the Republic of China, Mongolia, Finland and at the beginning of World War II against Germany in 1941. It was also used in various duties in civil variants, as trainers and in many secondary roles. Successful in the Spanish Civil War because it outpaced most fighters, the aircraft was obsolete by 1941. By June 1941, 94 percent of bombers in the Red Army air force (VVS RKKA) were SBs.



In 1933 the Soviet Air Force ministry (UVVS) issued an outline requirement for a high-speed bomber. Work on this proposal at TsAGI began in January 1934. The SB was designed and developed in the Tupolev KB ('Design Bureau') by a team led by A. A. Arkhangelski. Two versions were planned - with Wright Cyclone radial engines (ANT-40 RTs), and with the Hispano-Suiza 12Y liquid-cooled V12 engines (ANT-40 IS). The skills gained in the design of the MI-3 and DI-8 aircraft were widely used. The first two prototypes were designed as ANT-40.1 and ANT-40.2. The Cyclone powered prototype flew first, on 7 October 1934, while the first Hispano-Suiza powered prototype (ANT-401[1][2]), which featured a larger wing, flew on 30 December 1934, demonstrating superior performance.[3]

The second Hispano-Suiza powered aircraft, the ANT-402 was considered a production prototype, and its performance was impressive. It was however plagued by teething problems, leading unhappy test personnel to cover the ANT-402 with placards listing the aircraft's defects prior to a visit by Sergo Ordzhonikidze, the Commissar for Heavy Industry. On seeing these placards, Ordzhonikidze summoned Tupolev to a meeting at the Kremlin to discuss these shortfalls. When Tupolev stated that most of the defects were trivial, Joseph Stalin said:[4]

There are no trivialities in aviation; everything is serious and any uncorrected 'triviality' could lead to the loss of an aircraft and its crew.

The first production aircraft, designated SB, rolled off the production line before the end of 1935, and before ANT-402 had completed its flight test programme.[5] The aircraft entered full production in 1936, and was produced in two plants, State Aircraft Factory No 22 at Moscow and No 125 at Irkutsk until 1941.[6]

Despite the fact that the assembly lines were plagued with a constant string of modifications, some 400 SBs were delivered by the end of 1936—a number of these being diverted to Spain—and 24 VVS squadrons were in the process of working up with the new bomber.[7] Giving excellent performance in the Spanish Civil War, it acquired the popular name 'Katyusha' (Catherine).[8]

In 1937, negotiations were concluded between the Soviet and Czechoslovak governments, for the supply of SB bombers and a licence for local production, in exchange for the right to produce the Skoda 75 mm Model 1936 mountain gun. The version of the SB to be supplied to, and subsequently license-built as the Avia B-71 was the SB 2M-100A but fitted with the Avia-built Hispano-Suiza 12-Ydrs engine. A single 7.92 mm ZB-30 machine gun supplanted the twin ShKAS machine guns in the nose and similar weapons were provided for the dorsal and ventral stations.[9][10]

60 aircraft were to be flown to Czechoslovakia by mid-1938. The planned licensed production program took a decidedly leisurely course, despite the increasingly dangerous political situation. By 15 March 1939, when the German Wehrmacht occupied Bohemia and Moravia, not one Czech-built aircraft had been delivered.[9][10]

Development of the SB continued, meanwhile, with revisions being made to reflect the lessons of early operations in Spain. As problems were encountered in converting pilots to fly the SB, a trainer version, the USB was built in September 1937, with a modified nose with an open cockpit for an instructor and dual controls.[11][12] Problems were also encountered with the armament, the nose guns having limited traverse and so being little use against head-on attacks and later aircraft were modified with a better field of fire. From 1940, the dorsal gun position was replaced by an enclosed turret, while the ventral gun position, which was difficult to use, was also modified.[13][14]

The aircraft was also progressively fitted with improved engines. At first it was equipped with the Klimov M-100, a license-built version of the Hispano-Suiza 12Ybrs engine, but this was soon replaced by the more powerful M-100A, and from 1938 by the yet more powerful M-103. While the engine installation of the SB 2-M103 initially retained the drag inducing frontal radiators of the M-100 powered aircraft, an improved engine installation was developed with the radiators slung under the engines.[15] On 2 September 1937 M.Yu. Alexeev set an official altitude record of 12,246 m (40,177 ft) with load of 1,000 kg (2,200 lb) in an M-103 powered SB. He had earlier set an unofficial record of 12,695 m (41,650 ft).[16]

In an attempt to further improve the performance of the SB, which by 1939 was becoming obsolete, the development of two second-generation versions were authorised, a direct replacement for the SB and a specialised dive bomber. The level bomber, known as the SN-MN or MMN, had a new wing of reduced wing area and was powered by more powerful Klimov M-105 engines. Performance was little better than the standard aircraft and it was abandoned. The dive-bomber, designated SB-RK (later redesignated Arkhangelsky Ar-2 after its designer, with Tupolev having been imprisoned and being in disgrace) was similar to the MMN but was fitted with dive brakes and it was ordered into production.[17][18]

Even though the SB was no longer a state of the art aircraft, production continued to increase through 1939 and 1940, as the Soviet Union tried to build up the strength of their air forces to compete with the growing threat of Nazi Germany, with almost 4,000 being built in these two years.[19] The SB was phased out of production in early 1941, being replaced by the Petlyakov Pe-2.[20] A total of 5,695 were built at Factory No 22 at Moscow before it was evacuated to Kazan, while Factory No 125 built a further 1,136 at Irkutsk.[21] Three prototypes were built at the Tupolev design bureau,[21] while Aero Vodochody and Avia in Czechoslovakia built 45 and 66 respectively,[9][12] giving a total of 6,945 built.



The SB was an all-metal monoplane powered by two Klimov M-100 12-cylinder water-cooled engines (license production version of Hispano-Suiza 12-Yrds engine) which drove fixed-pitch two-bladed metal propellers. The engines were provided with honeycomb-type frontal radiators enclosed by vertical thermostat-controlled cooling shutters. At an early production stage, the M-100 engine gave place to an improved M-100A engine, driving ground-adjustable three-pitch propellers, with speed being boosted to 423 km/h (263 mph) at 4,000 m (13,000 ft). Because of its broad, high aspect ratio wing, that gave it a good altitude performance - Soviet crews nicknamed the SB the 'Pterodactyl'.[22]

Operational history

Operational history

There were a number of foreign customers for the SB. They were mostly satisfied with the aircraft's performance. There were some complaints about the high noise level, cramped crew compartments, hard undercarriage suspension and in particular about the front gunner's position, which could be reached only through a hatch under the fuselage, preventing the gunner from escaping in the event of a ditching or belly landing. Czechoslovakia signed an agreement to produce the ANT-40 as Avia B-71. [23]

Spanish Republican Air Force in the Spanish Civil War

Spanish Civil War

While only 54 SBs had been delivered to the Soviet Air Forces by 1 July 1936,[24] this did not stop the new Tupolev bomber being amongst the first shipments of military equipment sent by the Soviet Union to support the Spanish Republicans when the Spanish Civil War broke out on 17 July 1936. An initial batch of 31 SBs arrived in Cartagena aboard the Soviet Freighter Komsomol in October 1936, flying their first mission, a bombing raid by four SBs against Tablada airfield, Seville on 28 October. The SBs were used to equip Grupo 12 of the Spanish Republican Air Force, which at first was mainly manned by Soviet volunteers and under Soviet control.[25]

The SB could outpace the Fiat CR.32 and Heinkel He 51 biplane fighters of the nationalist forces, and was therefore difficult to intercept, with dives from high altitude being the only way to intercept the SB.[26] On 29 May 1937 two SBs attacked the German pocket battleship Deutschland, mistaking it for the Nationalist cruiser Canarias, killing 31 and injuring an additional 83 German sailors.[27] In June-July, a second consignment of 31 SBs were received, allowing Grupo 12 to return to full strength, and a new unit, Grupo 24, to be established.[28] The delivery of Messerschmitt Bf 109s to re-equip the German Condor Legion meant that the SB could no longer evade Nationalist fighters by sheer speed, and losses rose.[26]

A third and final batch of 31 SBs arrived in June 1938,[29] allowing operations to continue, although losses continued to be high. By the time the Civil War ended in April 1939, 73 SBs had been lost, 40 of them to enemy action.[26] Nineteen SBs were taken over by the Nationalists, and used to form a bomber squadron. Although some were re-engined with French Hispano-Suiza 12Ybrs engines to aid maintenance, they were still subject to spares shortages, and in April 1943 only three were airworthy. When Junkers Ju 88s were received in December 1943, the remaining SBs were used for occasional training flights until withdrawn and scrapped in 1948.[30]

Second Sino-Japanese War


In July 1937, the Second Sino-Japanese War broke out. The Soviet Union signed the Sino-Soviet Non-Aggression Pact on 21 August 1937, and as part of this agreement, supplied large amounts of military equipment to the Chinese Nationalists, as well as deploying complete air force units, nominally manned by Soviet volunteers. An initial delivery of 62 SBs was made in September-October 1937, with combat operations by Soviet forces starting in December with attacks on Japanese ships on the Yangtze River. On 23 February 1938, to celebrate Soviet Army Day, Soviet SBs carried out a long range attack on Japanese airfields on Taiwan, claiming 40 Japanese aircraft destroyed on the ground.[31][32]

A further 60 SBs were delivered to China in early 1938, these being heavily used to attack Japanese forces during the Battle of Wuhan. Losses were heavy, forcing the Chinese SB units to be temporarily withdrawn from combat. The Soviet units operating the SB over China re-equipped with the Ilyushin DB-3 in 1939, allowing their SBs to be transferred to Chinese units, but the Chinese made limited use of these reinforcements.[33]

The Soviet Union supplied a further 100 SBs in 1941, just before it signed the Soviet-Japanese Neutrality Pact. The SB was gradually phased out of front-line operations against the Japanese with the delivery of more modern American bombers from 1942, being partly replaced by Lockheed Hudsons and B-25 Mitchells. Limited numbers of SBs continued in non-combat use, including operations against opium plantations, before being used against the Communists when the Chinese Civil War flared up in 1945, being finally withdrawn in 1946.[32][34]



As well as the aircraft operated by volunteers against the Japanese over China, SBs were used in combat against the Japanese during the Fighting near Lake Khasan on the eastern sector of the China-Russia border in July-August 1938, one SB being lost.[35] Fighting between Soviet and Japanese forces broke out again at Khalkhin Gol in Eastern Mongolia in May 1939. While SBs were not involved in the May air battles, where the Soviet forces received heavy losses, two Regiments of SBs were deployed to Mongolia in June, flying their first missions on 26 June.[36]

SBs were used heavily against Japanese forces when they attacked in early July. The Soviet SB regiments consisted of a mixture of early and later SBs, whose differing speeds caused problems in maintaining formation, while Japanese Nakajima Ki-27 fighters proved adept in exploiting the poor defensive armament of the SB, with the radio operator operating both the dorsal and ventral guns.[35]

To minimise losses to Japanese fighters, the Soviets changed tactics, flying SB missions at over 6,100 m (20,000 ft) where it was difficult for the Japanese to intercept.[37]

SBs continued to be used against the Japanese as the Soviets and Mongolian forces commanded by Georgy Zhukov carried out many successful offensive operations until a cease-fire was signed in September 1939.

Winter War

Winter War

On 30 November 1939, the Soviet Union attacked Finland in the conflict that became known as the Winter War, with the forces deployed against Finland including several hundred SBs. Losses were heavy, with bomber formations often un-escorted, and forced to operate at low level, where they were vulnerable to Finnish anti-aircraft fire and fighters. While in 1936 in Spain, the SB could outpace enemy fighters, by now it was vulnerable and poorly armed. SBs were fitted with skis for operation from snow covered airfields, slowing the aircraft and making them more vulnerable, while the need to wear heavy winter clothing made the gunner's job even harder.[20][38] By the end of the 15-week war, at least 100 SBs had been lost,[19] with the Finns claiming nearly 200 shot down, 92 of them to Finnish fighters.[20][39]

Finnish use in the Continuation War

Many Soviet SBs crashed or force-landed on Finnish soil during the Winter War, with the Finns salvaging as many aircraft as possible, with those in the best condition being sent to Valtion lentokonetehdas for possible repair for use by the Finnish air force. By the time of the Continuation War against the Soviet Union, when Finland moved to recover the territory lost in the Winter War, five SBs had been repaired (with a further three added later), being used to equip Lentolaivue 6, flying maritime patrol and attack missions.[19][39] These aircraft were supplemented by a further 16 SBs purchased from Germany, which had captured them during the initial weeks of the invasion of the Soviet Union.[44] These SBs employed the first air-dropped depth charges used in combat. Finland lost seven SBs to accidents during the Continuation War, with none being lost in combat, with Finnish SBs claiming three Soviet submarines and a 4,000 ton merchant ship sunk.[45]

Soviet Union

Eastern Front

When Germany invaded the Soviet Union in June 1941, re-equipment with more modern aircraft such as the Pe-2 had begun. Still, 94% of the Soviet operational bomber force was equipped with SBs,[40] with 1,500-2,000 SBs deployed along the Western border districts of the Soviet Union.[41][42] The Luftwaffe started Operation Barbarossa with co-ordinated strikes against 66 major Soviet airfields,[41] destroying a large proportion of Soviet air strength on the ground or air on the first day of the invasion. The SBs that survived the carnage of the first day continued to be poorly used, many being frittered away in unescorted low-level attacks against German tanks, where the SB's relatively large size and lack of armour made it highly vulnerable to German light Flak, while German fighters continued to take a heavy toll. Within a few days, losses forced most of the remaining SBs to switch to night attacks.[42]

SBs continued to be used, in the defense of Leningrad and Moscow, mainly at night by attacking German artillery. By December 1941 almost all of the SBs had either been replaced or lost,[41] although it remained in large-scale use until March 1942 in the North against Finland.[42][43] SBs continued in use for non-combat roles such as supply dropping, glider towing and training, and continued in use in the Far East until 1945.[41]

The first eight aircraft (seven powered by M-103 engines, one by M-100 engines) were captured during the Winter War, another 16 aircraft were converted from German-captured material from 5 November 1941 - 27 August 1942. All aircraft were refitted with M-103 engines and were used as anti-submarine aircraft in the LeLv 6 squadron. Two aircraft were rebuilt and were used as trainers. The Finnish Air Force withdrew all SB aircraft in 1945, and all were scrapped in 1950.[19]

All were overhauled and Soviet M-100 engines were replaced with French Hispano Suiza 12Ybrs.
These aircraft were used operationally and later for training duties, and were retired in 1950.
Spanish pilots called captured SB bombers Katiuska.

Surviving aircraft

Surviving aircraft

After Stalin's post-war cleanup in the 1950s, many ANT-40s that survived the Second World War were scrapped. In the late 1970s, however, Vozdushni Transport (A Soviet aviation newspaper) sent an expedition led by Evgeny Konoplev to survey an ANT-40 that was forced to land during a snow storm near the Yuzhne Muiski mountain range in the Baikal region. Konoplev considered what they found encouraging, with the aircraft being in fairly decent condition, in turn leading a team of VVS pilots to recover the airplane. It was returned to Moscow and restored by a group of volunteer Tupolev employees. The restored aircraft was unveiled in April 1982 at the Central Air Force Museum at Monino Airfield. Another ANT-40 is displayed in Verhnyaya Pyshma.[57]

A reproduction of an SB-2 is under construction by the La Senia Airfield Association in La Sénia, Catalonia.[58]
