The US State Department has cleared Japan’s request to purchase additional KC-46A aerial refueling aircraft for $4.1 billion.
Tokyo seeks to acquire nine more KC-46As, along with 18 turbofan engines, 16 radar warning receivers, and 33 infrared countermeasure suites, according to a Defense Security Cooperation Agency (DSCA) announcement.
The request includes missile warning sensors, identification friend-or-foe transponders, and communications equipment to be integrated into the aircraft.
The potential deal will also cover spare parts, personnel training, training equipment, and engineering and logistics support services.
Once finalized, it will expand Japan’s KC-46A fleet to 15, complementing the four currently in operation and the two additional aircraft already ordered.
Boeing, Pratt & Whitney, RTX, and Northrop Grumman will be the principal contractors.
‘Supporting National Security Objectives’
Powered by two high-bypass turbofan engines, the KC-46A boasts a fuel capacity of 212,000 pounds (96,161 kilograms) and can refuel most fixed-wing aircraft.
It has a refueling boom driven by a fly-by-wire control system for seamless transfer of fuel mid-air.
It is also equipped with a sophisticated self-protection system to allow it to perform its missions in contested environments.
According to the DSCA, the expansion of Tokyo’s KC-46A fleet is expected to support the national security objectives of the US by bolstering the security of a key ally in the Indo-Pacific region.
It will also improve the Asian nation’s aerial refueling and passenger transport capabilities, contributing to a stronger deterrence against current and emerging threats.
