**Japan—KC-46A Aerial Refueling Aircraft**
The Government of Japan has requested to buy up to nine (9) KC-46A aircraft; up to eighteen (18) PW4062 turbofan engines; up to sixteen (16) AN/ALR-69A radar warning receivers (RWRs); up to thirty-three (33) Large Aircraft Infrared Countermeasure (LAIRCM) Guardian Laser Turret Assemblies (GLTAs); and up to eighteen (18) LAIRCM system processor replacements. The following non-MDE items will also be included: missile warning sensors; Cartridge Actuated Devices and Propellent Actuated Devices (CAD/PADs); control interface units; User Data Module (UDM) cards; electronic warfare database support; KIV-77 crypto modules; KY-100 crypto terminals; AN/PYQ-10 Simple Key Loaders (SKL); AN/APX-119 Identification Friend or Foe (IFF) transponders; communications equipment; Computer Program Identification Numbers (CPINS); integration and test support and equipment; aircraft components, parts, and accessories; support and support equipment; spare parts, consumables and accessories, and repair and return support; training aids, devices, and spare parts; minor modifications and maintenance support; instruments and lab equipment; classified and unclassified software delivery and support; facilities and construction support; unclassified publications and technical documentation; personnel training and training equipment; jet fuel; transportation and airlift support; warranties; studies and surveys; U.S. Government and contractor engineering, technical, and logistics support services; and other related elements of logistics and program support. The estimated total cost is $4.1 billion.
This proposed sale will support the foreign policy goals and national security objectives of the
U.S. by improving the security of a major ally that is a force for political stability and economic progress in the Indo-Pacific region.
The proposed sale will improve Japan's aerial refueling capability and passenger transport operations, which will contribute to enhanced deterrence of current and future threats in the region. Japan already has KC-46A aircraft tankers in its inventory and will have no difficulty absorbing these articles into its armed forces.
The proposed sale of this equipment and support will not alter the basic military balance in the region.
The principal contractors will be Boeing Corporation, located in Everett, WA; Pratt & Whitney Military Engines, located in East Hartford, CT; RTX Corporation, located in Goleta, CA; and Northrop Grumman Corporation, located in Rolling Meadows, IL. There are no known offset agreements proposed in connection with this potential sale.
Implementation of this proposed sale will not require the assignment of any additional U.S. Government or contractor representatives to Japan.
There will be no adverse impact on U.S. defense readiness as a result of this proposed sale.
