Lockheed Martin (NYSE: LMT) has reached a pivotal development milestone for the Next Generation Interceptor (NGI), successfully completing a critical burst test of its second-stage motor case and advancing the program toward Critical Design Review (CDR) later this year. Engineers filled the motor case with a carbon-fiber reinforced water vessel and inflated it beyond expected launch pressures. The motor case withstood the required induced loads before failure, validating the composite structure’s strength-to-weight ratio and confirming it can survive the extreme launch environment while delivering the thrust needed to place the interceptor’s payload into orbit. A faster fielding of NGI answers the call for an advanced missile defense capability. The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States’ Ground-Based Midcourse Defense (GMD) system. It is designed to intercept intercontinental ballistic missiles. Successfully completing the burst test marks another step forward in the program’s development, keeping it on track for CDR and production.
Other factors pushing NGI toward deployment completion include:
- Advanced design and speed: Leveraging NGI’s “born‑digital” foundation, designs that once required years of physical iteration can now be produced, fabricated and validated in a matter of months.
- Capital investments: Lockheed Martin is investing millions of dollars to construct or expand purpose-built manufacturing facilities in Alabama. This includes incorporating advanced manufacturing techniques, production lines, tooling and plant layouts to meet urgent production demand.
- Whole of Industry Support: Lockheed Martin is leveraging significant supply chain capabilities across the nation to delivery NGI.
“This successful burst test is a significant milestone on the path to CDR and brings us closer to fielding NGI by 2030,” said Christopher Jewell, vice president, Lockheed Martin NGI. “It proves our advanced motor architecture can withstand the harsh conditions of flight and still perform with the precision required to help protect the nation.”
The Next Generation Interceptor (NGI) is a MDA program to upgrade the kill vehicles for the ground-based interceptors, with different vendors, Lockheed Martin and Northrop Grumman competing. The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States’ Ground-Based Midcourse Defense (GMD) system. It is designed to intercept intercontinental ballistic missiles. This interceptor is made up of a boost vehicle, constructed by Orbital Sciences Corporation, and an Exoatmospheric Kill Vehicle (EKV), built by Raytheon. Integration of these is performed by Boeing Defense, Space & Security. The three-stage Orbital Boost Vehicle (OBV) uses the solid-fuel rocket upper stages of the Taurus launcher. The interceptor version deployed in the U.S. has three stages. the NGI is being engineered to handle more complex situations to be able to hit maneuverable targets. On 11 December 2023 a two-stage GBI intercepted an IRBM for the first time, using integrated sensor data from the RTX AN/TPY-2 in forward-based mode, and from the Sea-based X-band radar. On 15 April 2024, Lockheed Martin was selected over Northrop Grumman and awarded a $17 billion contract to develop the Next Generation Interceptor.
