Disbandment of the RNZAF air combat force
In May 2001 the Fifth Labour Government of New Zealand decided to disband the Royal New Zealand Air Force's air combat force by withdrawing its Douglas A-4K Skyhawk fighter aircraft and Aermacchi MB-339 trainers without replacement. This followed a debate over whether 28 General Dynamics F-16 A/B Fighting Falcon fighter aircraft should be leased from the United States to replace the Skyhawks.
