The U.S. State Department has approved a sale worth up to $13.9 billion of 36 Boeing [BA] F-15ID fighters and related equipment, the Defense Security Cooperation Agency (DSCA) said on Feb. 10.

DSCA said that it has notified Congress of the sale, which also could include 87 General Electric [GE] F110GE-129 or Pratt & Whitney [RTX] F100-PW-229 engines, 45 Raytheon [RTX] AN/APG-82(V)1 Advanced Electronically Scanned Array (AESA) raars, 45 BAE Systems‘ AN/ALQ-250 Eagle Passive Active Warning Survivability Systems (EPAWSS); 80 Joint Helmet Mounted Cueing Systems (JHMCS) by Collins Elbit Vision Systems, a joint venture of Collins Aerospace [RTX] and Elbit Systems of America [ESLT]; and 40 Lockheed Martin [LMT] AN/AAQ-33 Sniper Advanced Targeting Pods.

“This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of an important regional partner that is a force for political stability, and economic progress in the Asia-Pacific region,” DSCA said. “The proposed sale will improve Indonesia’s capability to meet current and future threats by enabling it to provide increased deterrence and air defense coverage across a very complex air and maritime domain. Indonesia will have no difficulty absorbing these aircraft and equipment into its armed forces.”

The DSCA announcement came the same day that French Minister of the Armed Forces, Florence Parly, the Indonesian Minister of Defence, Prabowo Subianto, and Dassault Aviation CEO Eric Trappier inked an agreement in Jakarta for Indonesia to buy 42 Rafale fighters.
