Northrop F5E Tiger II "Peace Bell Program"(Yemen Air Force, Taiwan)

Republic of China Armed Forces engaged in a classified military aid program in the Yemen Arab Republic known as the Peace Bell Program or the Great Desert Program (????) at the behest of Saudi Arabia. The Taiwanese piloted Yemeni F-5s and manned air defense batteries against a South Yemeni force composed of Cuban and Soviet personnel. The program ended in 1990 when Saudi Arabia withdrew its diplomatic recognition of Taiwan. The ROCAF force were actively involved in combat with the Cubans/Soviets and for all intents and purposes constitutes the Yemen Arab Republic's Air Force during this time. Taiwanese pilots scored a number of kills and the air-defense and early warning radar teams took casualties from aerial attacks.
