The US State Department has approved the sale of two Aegis Weapon Systems (AWS) and associated equipment to the Japanese Navy, in a deal valued at around $2.15bn.
Japan will also receive two multi-mission signal processors (MMSP) and two command and control processor (C2P) refreshes, radio navigation equipment, naval ordnance, two identification friend or foe systems, global command and control system-maritime hardware, and two inertial navigation systems.
Other equipment included in the sale are technical, engineering and logistics support services, installation support material, training, construction services for six vertical launch system launcher module enclosures.
In addition, the US will deliver communications equipment and associated spares, classified and unclassified publications and software, and other associated elements of logistical and program support.
The US Defense Security Cooperation Agency (DSCA) has notified Congress of the potential foreign military sale.
In a statement, DSCA said: “This proposed sale will contribute to the foreign policy and national security of the US by improving the security of a major ally that is a force for political stability and economic progress in the Asia-Pacific region.
“It is vital to US national interests to assist Japan in developing and maintaining a strong and effective self-defence capability.”
With the purchase of the weapon systems, the Japanese Navy expects to have an enhanced capability against increasingly sophisticated ballistic missile threats and better safeguard its homeland. The Asian nation already has the Aegis system in its inventory.
While Lockheed Martin Rotary and Mission Systems will supply the AWS and MMSP, General Dynamics will provide C2P refreshes.
Under the deal, the US Government and contractor representatives will visit Japan multiple times to provide technical reviews, support, and oversight for around eight years.
Aegis is a maritime ballistic missile defence system that can simultaneously attack land targets, submarines, and surface ships while also automatically tackling the threat of aircraft, cruise missiles, and ballistic missiles.
