In August of 1986, Indonesia signed a letter of agreement for 12 F-16A/B Block 15 OCU (Operational Capability Upgrade) aircraft. They were intended to replace some of the aging MiG-21 fighters and other Soviet types that were in service in Indonesia.
The first F-16 was delivered to the Tentara Nasional Indonesia-Angatan Udara (Indonesian National Army-Air Force) on December 11, 1989. Deliveries were completed in 1990. These aircraft equipped Skwadron Udara 3, based at Ishwahyudi Air Base on the island of Java. This unit had previously operated the OV-10F Bronco, the Broncos being used to reactivate SkU.1.
In November of 1995, Indonesia expressed a need for 64 more F-16s, enough to equip four fighter squadrons. They expressed an interest in the 28 embargoed Pakistani F-16s held in storage at AMARC. A contract was signed in 1996 for nine Block 20 F-16s. However, negotiations between the USA and Indonesia for the purchase of these planes were postponed in June of 1997 because of Congressional objections to Indonesia's human rights record following riots in June of 1996.
