Lockheed Martin has announced the successful completion of a static-fire test of the Stage 2 rocket motor being developed for its Next Generation Interceptor (NGI) programme. The test represents an important milestone in the development of the interceptor and supports the programme’s progress toward its upcoming Critical Design Review.
The Stage 2 motor, developed by L3Harris Technologies, was fired inside a high-vacuum test chamber designed to recreate conditions similar to those encountered during operations in low-Earth orbit. The test was conducted to assess the motor’s ability to withstand the thermal and pressure conditions expected during an interceptor mission.
According to Lockheed Martin, the test successfully demonstrated key motor performance parameters, including thrust, chamber pressure and combustion stability. The data collected during the test will be used to support the final design of the NGI and its integration with the Ground-Based Midcourse Defense (GMD) architecture.
Christopher Jewell, Lockheed Martin NGI Vice President, said the successful test represents a significant step toward the programme’s Critical Design Review and strengthens confidence in meeting the demanding performance requirements targeted for fielding by 2030.
The NGI programme is being developed to provide an advanced interceptor capability for the United States’ missile defence architecture. The system is intended to strengthen the GMD system’s ability to counter sophisticated ballistic missile threats and provide an additional layer of protection against potential attacks.
Lockheed Martin said the programme is benefiting from a digital engineering approach that allows designs to move more rapidly through development, manufacturing and validation. The company is using its digital capabilities to reduce development cycles and accelerate the transition from design concepts to hardware.
The company is also investing in manufacturing infrastructure to support NGI production requirements. These investments include new and expanded facilities in Alabama, advanced manufacturing technologies, production equipment, tooling and dedicated production lines. The programme is supported by a broad network of suppliers and industrial partners across the United States. Lockheed Martin said its industry-wide approach is intended to strengthen the supply chain and support the programme’s production objectives.
The latest motor test follows other development activities aimed at moving NGI toward operational deployment. The information generated through testing will contribute to future design decisions and system-level integration as the programme advances toward the next stages of development.
