Northrop Grumman in Japan

Providing a range of capabilities and technologies for the Japan Self-Defense Force.

Northrop Grumman has a long history in Japan dating back to the late 1950s when the Japan Self-Defense Force (JSDF) used the Grumman Avenger aircraft for maritime patrol, the Albatross aircraft for search and rescue, and the Tracker aircraft for anti-submarine warfare. This close partnership with Japan continues today with Northrop Grumman providing support to all the major branches of the JSDF on a range of defense, security and information systems programs.

E-2D Advanced Hawkeye

In 2014 the Japan Ministry of Defense selected the E-2D Advanced Hawkeye to fulfill the nation’s evolving airborne early warning and command and control (AEW&C) requirements. The E-2D is an all-weather, tactical battle management AEW&C aircraft. The aircraft’s updated sensor suite and network connectivity provide seamless information flow among aircraft, ships, soldiers, civilians and command authorities to quickly distribute information for more accurate and timely decision-making. In a peacetime environment, the Hawkeye’s sophisticated capabilities can play an important role in disaster relief and in the protection of national borders, including anti-smuggling and anti-piracy efforts. In addition, the Japan Air Self-Defense Force (JASDF) operates 13 Northrop Grumman E-2C Hawkeye Airborne Early Warning and Control aircraft. The JASDF is the largest international Hawkeye customer.

RQ-4B Global Hawk

The RQ-4B Global Hawk unmanned aircraft system is a versatile platform capable of carrying multiple payloads and collecting a wide variety of intelligence data while flying for more than 30 hours at altitudes of up to 60,000 feet. The Global Hawk’s sensors can capture intelligence information over both land and sea. The Global Hawk aircraft can be equipped with the intelligence, surveillance and reconnaissance (ISR) payload adapter to enable the aircraft to carry future sensor payloads.

In 2014 the Japan Ministry of Defense selected the RQ-4B Global Hawk to be an integral part of the nation’s ISR assets. The Global Hawk will be an important ISR asset for the Japan Self-Defense Force within the geopolitical environment of the Asia-Pacific region. Its intelligence-gathering capabilities will also give Japan a greater ability to respond to natural disasters.

Integrated Air and Missile Defense Battle Command System (IBCS)

Developed in partnership with Northrop Grumman, the Integrated Air and Missile Defense Battle Command System (IBCS) is the centerpiece of the U.S. Army’s modernization strategy for air and missile defense capability. By networking any sensor with the best effector, IBCS will deliver the most advanced, battle survivable command and control (C2) system for U.S., joint and coalition forces, providing revolutionary multi-domain defense capabilities that will enhance lethality against current threats and enable growth to address future threats.

Advanced Anti-Radiation Guided Missile – Extended Range (AARGM-ER)

Northrop Grumman’s AARGM-ER is a supersonic, air-launched tactical missile that allows aircraft to defend themselves against any adversary system threatening their safety.

The AARGM is the most advanced system available for pilots to defend against modern surface-to-air threats. It is able to rapidly detect and then fly out to defeat even distant land- and sea-based air-defense systems that are targeting friendly operations.
