The Indonesian Air Force (Tentara Nasional Indonesia - Angkatan Udara, TNI-AU) received the first three of 24 Lockheed Martin F-16C/D aircraft on 25 July.
The F-16s, which are being upgraded from Block 25 to Block 52 standard by the US Air Force (USAF) at Hill Air Force Base's (AFB) Ogden Air Logistics Complex (ALC) in Utah, are former USAF and Air National Guard units that were transferred to Indonesia as excess defence articles under a contract signed in January 2012.
The Indonesian government is paying about USD670 million to upgrade the aircraft with new avionics, engines, wings, landing gear and other components. According to official US Air Force media the USAF handed over one F-16C and two F-16Ds on 14 July. The remaining 21 aircraft are scheduled to be delivered to the Indonesian government by Ogden ALC by the end of 2015.
The three aircraft landed at Iswahjudi Airbase in Madiun, East Java, after flying from Alaska via Guam. In August, six Indonesian Air Force instructors will begin F-16C/D conversion training under the tutelage of a four-man USAF Mobile Training Team. The 24 aircraft will be split between Squadron 3 at Madiun and Squadron 16 at Pekanbaru.
Local Indonesian media have reported that the refurbishment includes service life extensions, including the overhaul of the wings, landing gear, and engines, as well as capability enhancements to avionics. These include an upgraded AN/APG-68 (V) fire control radar and Block 52 Link 16 datalink, AN/ALQ-213 Electronic Warfare Management System, ALR-69 Class IV Radar Warning Receiver, and ALE-47 Countermeasures Dispenser Set.
