The USAF provided attack, airlift, and combat support capability for operations in Grenada in 1983 (Operation Urgent Fury), Libya in 1986 (Operation El Dorado Canyon), and Panama in 1989 (Operation Just Cause). Lessons learned in these operations were applied to its force structure and doctrine, and became the basis for successful air operations in the 1990s and after September 11, 2001.
