The Ugandan Air Force traces its history to 1964, when the country's first air force was established with Israeli aid. This military branch was officially called "Uganda Army Air Force" (UAAF). Its first aircraft was of Israeli origin, and its initial pilots trained in Israel. As Uganda's government forged closer links with the Eastern Bloc, the UAAF began to acquire more aircraft as well as support in training from the Soviet Union, Czechoslovakia, and Libya. Israeli aid initially continued as well. After Idi Amin seized power during the 1971 Ugandan coup d'état, the Uganda Army, including its air force, were further expanded. At the same time, corruption and infighting increased, while foreign aid began to decline, reducing the UAAF's ability to operate.
