Accelerating the Next Generation Interceptor Program

Lockheed Martin is working to expedite its Next Generation Interceptor (NGI) program, which is intended to enhance U.S. defenses against intercontinental ballistic missile (ICBM) threats. Sarah Reeves, the company’s vice president, noted that the program is currently facing a 1.5-year delay. However, a funding boost from President Trump’s proposed Golden Dome missile defense shield could reverse this trend.

To streamline the NGI program, the Missile Defense Agency (MDA) has opted to shorten the competition timeline and selected Lockheed Martin, along with its partner L3Harris’ Aerojet Rocketdyne, to proceed. MDA Director Lt. Gen. Heath Collins indicated that this decision was made in April 2024, influenced by funding and priority considerations.

Reeves elaborated on the importance of “rigorous testing” and ensuring seamless integration into the broader defense system to deliver a capable interceptor. She emphasized a dual focus on maintaining a reliable schedule while also ensuring high technical performance.

According to Collins, the primary risk for the program is the development timeline for a new solid rocket motor. This aspect of the project has encountered delays, pushing the expected delivery of the initial system capability back by at least 18 months. In response, MDA has implemented measures to enhance development and is seeking additional resources to mitigate the associated risks.

The original schedule aimed for an initial operational capability for NGI by the fourth quarter of fiscal 2028. Meanwhile, details on the Golden Dome initiative remain under wraps, with government officials advised not to publicly discuss the extensive project at the ongoing Space and Missile Defense Symposium in Huntsville.

Trump previously projected an investment of around $175 billion into the Golden Dome, with an ambitious goal of completing it by 2028. The current Ground-based Midcourse Defense (GMD) system consists of 40 silos in Alaska and 4 in California. Earlier this year, Boeing completed the construction of 20 additional silos in Fort Greely, a plan initiated during Trump’s previous term.

There have also been proposals for more silos at Fort Greely and the installation of interceptors on the U.S. East Coast. Lawmakers from the region have advocated for this concept for over a decade, but progress has been slow due to other funding priorities. MDA leadership maintains that the existing GMD configuration sufficiently meets current defense needs.

Reeves mentioned that while NGI is concentrating on the critical design review, construction is actively underway for a missile assembly facility in Cortland, Alabama, which is expected to be completed by early 2026. The program has also fostered partnerships with various businesses since 2021 to ensure a robust capability for national defense. Reeves concluded by emphasizing the importance of these partnerships in establishing a strong defense framework, describing the initiative as “foundational” for the country.
