On November 13, 2024, the United States Department of Defense announced a significant funding increase for American Defense Company Northrop Grumman Systems Corporation’s work on the Glide Phase Interceptor (GPI) program, an advanced defense initiative designed to counter hypersonic missile threats. Northrop Grumman, based in Chandler, Arizona, has been awarded five additional one-year firm-fixed-price options under its current Research & Development Prototype Other Transaction Authority (OTA) agreement.Follow Army Recognition on Google News at this link

The Glide Phase Interceptor (GPI) is an advanced missile defense system specifically designed to counter hypersonic missiles during their “glide phase” of flight. Hypersonic missiles, which can travel at speeds exceeding Mach 5, have a unique flight path that includes a boost phase, where they ascend to their intended altitude, followed by a glide phase, where they travel at high speeds and low altitudes, maneuvering unpredictably toward their target. Traditional missile defense systems often struggle to intercept such missiles due to their speed and maneuverability, particularly during the glide phase when they can adjust their trajectory to avoid interception. The GPI aims to address this by offering a precise defense capability during this phase, leveraging advanced guidance and propulsion systems to intercept and neutralize hypersonic threats before reaching their targets.
For military forces, the development of the GPI offers a transformative addition to missile defense capabilities, filling a critical gap in intercepting fast, agile hypersonic missiles. By targeting threats in the glide phase, the GPI provides military forces with a new layer of defense that protects strategic assets, infrastructure, and civilian areas from next-generation missile attacks. Additionally, integrating the GPI with existing systems like the Aegis Ballistic Missile Defense system allows for seamless deployment on naval vessels, offering a mobile, flexible, and scalable defense solution. This capability not only strengthens defensive postures against adversaries equipped with hypersonic technology but also reinforces deterrence, reducing the likelihood that such advanced weapons could penetrate allied defenses. In modern warfare, the GPI represents a strategic leap forward, enhancing the resilience and adaptability of military forces in high-stakes, high-speed threat environments.
This contract modification boosts the funding for Northrop Grumman’s GPI development from $291.8 million to $832.8 million—a $540.9 million increase aimed at accelerating work on this critical project. The expansion aligns with an MDA press release that confirms the continuation of Northrop Grumman’s work under the OTA agreement. Additionally, $24.6 million in Fiscal Year 2025 research, development, testing, and evaluation funds have been allocated for the project, which is expected to extend through November 2029.
The GPI initiative is a pioneering U.S.-Japan collaboration aimed at countering the unique challenges posed by hypersonic missiles during their glide phase when they maneuver at extreme speeds and low altitudes. This partnership, formalized in May 2024, designates the U.S. Missile Defense Agency (MDA) as the program’s lead, with Japan contributing essential technologies, including advanced rocket motors and propulsion systems. In September 2024, Northrop Grumman was selected as the primary contractor for the GPI project, entrusting the company with refining the interceptor’s design to ensure its effectiveness against hypersonic threats.
The GPI interceptor is designed to integrate with the U.S. Navy’s Aegis Ballistic Missile Defense (BMD) system, utilizing the widely deployed Vertical Launch System (VLS). This compatibility with Aegis allows the interceptor to be deployed on U.S. Navy ships, significantly enhancing the fleet’s defensive capabilities against hypersonic threats without requiring extensive modifications. As a result, the GPI program is set to provide a scalable, sea-based solution to the pressing challenge of intercepting advanced hypersonic weapons.
Hypersonic missiles, which can exceed Mach 5 speeds and evade traditional missile defenses through rapid maneuverability, represent a major strategic threat. The GPI aims to deliver an interception capability currently lacking in most global defense systems by intercepting such threats during their glide phase. The system’s development is both a technological advancement and a strategic imperative, as both the U.S. and Japan are committed to bolstering security in the Indo-Pacific region amid rapidly evolving missile technology.
The increase in funding for Northrop Grumman underscores the United States’ commitment to advancing its missile defense capabilities in close partnership with Japan. This collaboration represents a vital step in countering modern missile threats, strengthening allied defense postures, and ensuring stability in a dynamic global security environment. Once operational, the GPI program could become a critical element in regional defense, enhancing readiness against new-age missile threats and exemplifying allied cooperation in cutting-edge defense innovation.
