Northrop Grumman to Produce First Hypersonic Glide Phase Interceptor
September 30, 2024 | Northrop GrummanEstimated reading time: 1 minute

The U.S. Missile Defense Agency (MDA) will proceed with Northrop Grumman Corporation for the Glide Phase Interceptor (GPI) program, the first-of-its-kind defensive countermeasure against hypersonic missile threats. Working in close partnership with MDA, the three-year developmental effort produced a purpose-built, innovative design capable of defeating existing and emerging hypersonic threats.
During this next phase of development, Northrop Grumman will:
- Continue to refine the preliminary design of the GPI, which will fire from the U.S. Navy’s Aegis Ballistic Missile Defense destroyers and Aegis Ashore using the standard Vertical Launch System
- Demonstrate system performance in hypersonic environments prior to conducting its Preliminary Design Review
- Complete flight experiments ahead of schedule leveraging the company’s own flight-proven systems
- Use digital engineering practices to connect the entire GPI program to accelerate design processes and develop interceptor capabilities faster and more efficiently
Expert:
Wendy Williams, vice president and general manager, launch and missile defense systems, Northrop Grumman: “GPI adds mission critical standoff to warfighters in scenarios where distance creates an advantage. Tailorable to a multitude of mission requirements, Northrop Grumman’s revolutionary solution is designed to perform in the evolving threat landscape.”
Details:
Northrop Grumman’s design includes advanced technologies, such as a seeker for threat tracking and hit-to-kill accuracy, a re-ignitable upper stage engine used for threat containment and a dual engagement mode to engage threats across a wide range of altitudes.
Northrop Grumman will work closely with the United States in support of its role under the GPI Cooperative Development program with the Japan Ministry of Defense to deliver interceptors to the MDA.

Elementary Mr. Watson: Retro Routers vs. Modern Boards—The Silent Struggle on Your Screen
06/26/2025 | John Watson -- Column: Elementary, Mr. WatsonThere's a story about a young woman preparing a holiday ham. Before putting it in the pan, she cuts off the ends. When asked why, she shrugs and says, "That's how my mom always did it." She asks her mother, who gives the same answer. Eventually, the question reaches Grandma, who laughs and says, "Oh, I only cut the ends off because my pan was too small." This story is a powerful analogy for how many PCB designers approach routing today.

Cadence AI Autorouter May Transform the Landscape
06/19/2025 | Andy Shaughnessy, Design007 MagazinePatrick Davis, product management director with Cadence Design Systems, discusses advancements in autorouting technology, including AI. He emphasizes a holistic approach that enhances placement and power distribution before routing. He points out that younger engineers seem more likely to embrace autorouting, while the veteran designers are still wary of giving up too much control. Will AI help autorouters finally gain industry-wide acceptance?
Beyond Design: The Metamorphosis of the PCB Router
06/18/2025 | Barry Olney -- Column: Beyond DesignThe traditional PCB design process is often time-consuming and labor-intensive. Routing a complex PCB layout can consume up to 30% of a designer’s time, and addressing this issue is not straightforward. We have all encountered this scenario: You spend hours setting the constraints and finally hit the Go button, only to be surprised by the lack of visual appeal and the obvious flaws in the result.
