Known by NATO as “The Beast”, 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.

In October 1944, the Il-10 first entered service with training units in the Soviet Air Force. In January 1945, the first Il-10 combat unit entered service with the 78th Guards Assault Aviation Regiment, but it did not enter action due to unfinished training. However, three other Il-10 units managed to take part in the final combat actions of World War II in Europe. They were the 571st Assault Aviation Regiment (from April 15th, 1945), the 108th Guards Assault Aviation Regiment (from April 16th, 1945), and the 118th Guards Assault Aviation Regiment (on May 8th, 1945). About a dozen aircraft were destroyed by flak or engine breakdowns, but the Il-10 appeared to be a successful design. One was shot down by an Fw-190 fighter, but a crew of the 118th Regiment shot down another Fw 190 and probably damaged another. On May 10th, 1945, the day after the official Soviet end of the war, (Victory Day), there were 120 serviceable Il-10s in Soviet Air Force combat units, and 26 disabled ones.

After the USSR reentered the war against the Empire of Japan, with the invasion of Manchuria, from August 9th, 1945, one Il-10 unit, the 26th Assault Aviation Regiment of the Pacific Navy Aviation, was used in combat in the Korean Peninsula, attacking Japanese ships in Rasin and rail transports.

After the war, until the early 1950s, the Il-10 was a basic Soviet ground attack aircraft. It was withdrawn from service in 1956. At the same time, work on new jet-powered dedicated armored ground attack planes (like the Il-40) was canceled, and the Soviets turned to multipurpose fighter-bomber aviation. The Il-10 and its licensed variant, the Avia B-33, became a basic ground attack plane of the Warsaw Pact countries. From 1949 to 1959, the Polish Air Force used 120 Il-10s (including 24 UIl-10), and 281 B-33s. In Poland, the B-33 was modified to carry 400 l fuel tanks under its wings. From 1950 to 1960, Czechoslovakia used 86 Il-10s, including six UIl-10s, and about 600 B-33s. From 1949 to 1956, the Hungarian Air Force used 159 Il-10s and B-33s. From 1950 to 1960, the Romanian Air Force used 14 Il-10s and 156 B-33s. Bulgaria also used these aircraft.

In the late 1940s, 93 Il-10 and UIl-10s were given to North Korea. They were then used in the 57th Assault Aviation Regiment during the early phase of the Korean War. They were initially used with success against the weak anti-aircraft defense of South Korean forces (following the US refusal to supply the south with “heavy weapons”), but then they suffered heavy losses in encounters against the United States Air Force fighters and were bombed on the ground themselves. After several weeks, about 20 remained. In the summer of 1950, North Korea received more aircraft from the USSR. The North Koreans claimed that they sank a warship on 22 August 1950 with Il-10s, but it was never confirmed.
