Taken from US DSCA release:
The US State Department has made a determination approving a possible Foreign Military Sale (FMS) to Australia for AIM-120D Advanced Medium-Range Air-to-Air Missiles (AMRAAM) and associated equipment, training, and support. The estimated cost is $1.6 billion. The Defense Security Cooperation Agency delivered the required certification notifying Congress of this possible sale on April 21, 2016.
The Commonwealth requested a possible sale of:
Major Defense Equipment (MDE):
This request also includes the following Non-MDE: containers, weapon system support equipment, support and test equipment, site survey, transportation, repair and return warranties, spare and repair parts, publications and technical data, maintenance, personnel training, and training equipment, US Government and contractor representative engineering, logistics, and technical support services, and other related elements of logistics support.
The total estimated value of MDE is $1.42 billion. The total overall estimated value is $1.6 billion.
This proposed sale is in support of the Royal Australian Air Force’s (RAAF) F/A-18, E/A-18G, and F-35 aircraft. This proposed sale will provide the RAAF additional air-to-air intercept capability and increase interoperability with the US Air Force. The proposed sale of this equipment will not alter the basic military balance in the region.
The principal contractor for production is Raytheon in Tucson, Arizona. The principal contractor for integration is unknown and will be determined during contract negotiations. There are no known offset agreements proposed in connection with this potential sale.
Implementation of this sale will not require the assignment of any additional US or contractor representatives to Australia.
This notice of a potential sale is required by law and does not mean the sale has been concluded.
