context_page_description: The Ilyushin Il-10 was a Soviet ground attack aircraft developed at the end of World War II by the Ilyushin construction bureau. It was also license-built in Czechoslovakia by Avia as the Avia B-33.
context_section_description: On 23 August 1944 the Il-10 was ordered into serial production by decision of the State Defense Committee (GKO) as a new ground attack plane. Its armament was initially similar to late model Il-2s, with two 23 mm VYa-23 cannons and two ShKAS machine guns in the wings, and a 12.7 mm UBT machine gun for a rear gunner, and 400 kg, or a maximum 600 kg of bombs. Unlike the Il-2 and Su-6, it was not initially meant to carry rockets.
  Production of the Il-10 started in Kuybyshev's factories No. 1 and No. 18. The first production aircraft flew on 27 September 1944 and 99 aircraft were produced by the end of 1944. Early series aircraft showed teething problems, most notably engine faults and fires. Most problems were eliminated by 1945. Aircraft produced from April 1945 onwards could carry four unguided air-to-ground rockets. Aircraft produced from 1947 onwards were fitted with stronger armament, consisting of four 23 mm NS-23 cannons in the wings and a 20 mm cannon for the rear gunner. Il-10 production ended in 1949, after a run of 4,600 aircraft; in the last two years, they were produced in factory No. 64.
  Between 1945 and 1947, 280  UIl-2 or Il-10U trainer variants were produced. The rear gunner' cockpit was replaced with a longer instructor's cockpit with dual controls. Its performance and construction were similar to the combat variant apart from armament, which was reduced to two cannons, two rockets, and a standard load of bombs.
  In 1951, the Czechoslovak firm Avia secured a license to make Il-10s, with the designation B-33. The first one flew on 26 December 1951. Initially, their engines were Soviet-built. From 1952 onwards the engines were also produced in Czechoslovakia as the M-42.  Besides the combat variant, a Czechoslovak trainer variant also entered service under the designation CB-33. In total, 1,200 B-33s were built by 1956.
  In 1951, due to experience acquired during the Korean War, the Soviet Air Force decided that propeller ground attack aircraft might still be useful, and decided to renew Il-10 production in a modified variant, the Il-10M, which first flew on 2 July 1951. It was slightly longer, with a wider wingspan, and larger control surfaces, with a fin under the tail. Four of the more recently developed NR-23 cannons were mounted in the wings, while the payload stayed the same, and newer navigation equipment was installed, giving partial all-weather capability. Speed decreased slightly, but handling improved. Between 1953 and 1954, 146 Il-10Ms were made, all but 10 in Rostov-on-Don's factory No.168.
  In total, 6,166 of all Il-10 variants were made, including those built under license.
  Trials of Il-10s mounted with more powerful AM-43 and AM-45 engines took place, but proved unsuccessful. Ilyushin next designed a lighter close support aircraft, the Il-16, with improved performance and similar armament. It first flew on 10 June 1945. A short run entered production, but the project was cancelled in 1946 due to the AM-43 engine's unreliability.
