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.

Key Programs and Capabilities for Japan

Northrop Grumman to Support US-Japan Glide Phase Interceptor Cooperative Development Agreement

Glide Phase Interceptor Cooperative Development Agreement

Under the Glide Phase Interceptor (GPI) Cooperative Development agreement, the U.S. Missile Defense Agency and Northrop Grumman will collaborate with the Japanese Ministry of Defense and its industry partners to develop elements of the interceptor. The Japanese-provided systems will be integrated into the GPI All-Up-Round.

MQ-8C Fire Scout

Fire Scout is a combat proven, autonomous helicopter system that provides real-time Intelligence, Surveillance, Reconnaissance, and Target-acquisition (ISR&T), laser designation, and battle management to tactical users without relying on manned aircraft or space-based assets. Fire Scout has the ability to operate from any air-capable ship or land base in support of persistent ISR&T requirements.

MQ-4C Triton

Based on the proven Global Hawk unmanned aircraft system (UAS), Triton is equipped with a unique and robust mission sensor suite that provides 360-degree coverage on all sensors. It will provide round-the-clock maritime wide-area ISR for the U.S. Navy and Royal Australian Air Force. The U.S. Navy first deployed the Triton to Guam in 2020, where it quickly became an “invaluable asset.

Integrated Battle Command System (IBCS)

To be fielded by the U.S. Army, the Integrated Battle Command System (IBCS) implements a modular, open and scalable architecture that is foundational to integrating available assets in the battlespace, regardless of source, service or domain. Its architecture enables the efficient and affordable integration of current and future systems and extends the battlespace by disaggregating sensors and effectors. Northrop Grumman is pioneering joint all-domain command and control with IBCS.

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

AARGM-ER is a supersonic, air-launched tactical missile system that will allow pilots to defend against today’s 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.

AARGM-ER will provide vital counter-air-defense capability for U.S Navy, Air Force and Marine Corps warfighters. It is being integrated on the Navy F/A-18E/F Super Hornet and EA-18G Growler aircraft as well as the F-35 aircraft.

Electronic Warfare and Attack

Northrop Grumman’s electronic warfare and electronic attack systems protect surface ships and aircraft from missiles, providing early detection, signal analysis and threat warning. Once the system detects an incoming threat, it responds by emitting tight blasts of precisely controlled radio-frequency energy.

Space Domain Awareness

Space Domain Awareness (SDA) allows the tracking of human-made objects in space with timely and precise orbital predictions. As the world increases its reliance on space for economic, scientific, and national security needs, governments have made SDA a top priority. For over a decade, Northrop Grumman has delivered ground and space products to monitor the space environment and aid in the detection, identification, and characterization of space objects. We are a world leader in rendezvous and proximity operations in LEO and GEO providing our customers critical logistics, servicing, and inspection capabilities across a wide variety of mission domains.
