Lockheed Martin advances next-generation hypersonic glide body with manufacturing-first approach

Lockheed Martin on June 24 announced it is accelerating development of a next-generation hypersonic glide body it says is designed to bring long-range strike capability to warfighters in a way that is more affordable and scalable than current approaches. The company positions NXGB, or next generation glide body, as a deterrence-focused weapon concept that combines advanced hypersonic performance with “manufacturing-first” design choices intended to reduce cost and speed production.

In a company update, Lockheed Martin described NXGB as an operationally relevant long-range strike option that is “rapidly producible” and built to support what it called the nation’s growing need for scaled production. The firm said the glide body is intended to be launched from multiple platforms and across multiple warfighting domains, which it said could improve operational flexibility in contested environments while reducing risk to U.S. forces.

The update also tied NXGB’s design goals to survivability and scalability, while asserting that it delivers greater range and velocity than current designs. Lockheed Martin did not provide performance figures, range estimates, or velocity numbers in the release, focusing instead on development milestones and production-oriented engineering choices.

Lockheed Martin said NXGB leverages more than six decades of missile development expertise and incorporates technologies, engineering practices, and lessons learned from successful fielded systems. The company added that it has made “significant investments” in purpose-built manufacturing infrastructure and advanced production capabilities, alongside supply chain partnerships, as part of its plan to scale production if and when the program moves forward.

The company said NXGB successfully completed Preliminary Design Review, described as a step that confirms the design meets “stringent criteria” for performance, producibility, and affordability. Preliminary Design Review is a formal engineering checkpoint used in defense programs to validate that the emerging design can meet stated requirements before proceeding deeper into detailed engineering and integration. Lockheed Martin did not disclose which customers, government agencies, or contract vehicle are associated with the review in the release.

Lockheed Martin’s vice president and general manager for Strategic and Missile Defense Systems, Johnathon Caldwell, said the company designed NXGB to deliver value to customers while providing an operational advantage to warfighters. Caldwell framed the effort as part of a broader deterrence goal that is “effective” and also “affordable and producible at scale,” emphasizing speed of production and cost reduction as core design requirements rather than after-the-fact adjustments.

In a second quoted statement, Caldwell said the future of deterrence belongs to solutions that combine a Modular Open Systems Approach with modern design methods while still relying on proven performance. The Modular Open Systems Approach generally refers to designing software and hardware with standardized interfaces so components can be updated, swapped, or scaled more easily across different systems and future upgrades. Lockheed Martin said NXGB reflects a design-for-manufacturing paradigm shift intended to help the company “move faster” and reduce risk and cost while maintaining performance, drawing on prior experience producing mission-critical systems.

Lockheed Martin said NXGB is slated for a 2027 flight demonstration to validate performance. The release did not specify the demonstration’s location, the launch platform, test range details, or the specific metrics that will be used to measure success. It also did not address timelines for subsequent steps, such as advanced engineering, system integration, operational testing, or any potential production decision.

Still, the company’s emphasis on manufacturability, scalability, and affordability suggests that NXGB’s development is being steered not only by physics and flight performance, but also by how quickly and how cheaply a weapon system could be produced at volume. For now, the public details remain high-level: beyond the Preliminary Design Review milestone and the 2027 flight demonstration schedule, Lockheed Martin did not provide additional program documentation, classified performance parameters, or procurement estimates.
