Ushering in a new era for faster, more survivable, highly capable weapons.

Scramjet Hypersonic Propulsion

Scramjet technology ushers in a new era for faster, more survivable, highly capable weapons. Not only does scramjet propulsion advance speeds greater than Mach 5 and maneuverability never seen before in traditional missiles, but it also leads to a smaller form factor missile while offering more capability. This means platforms can carry more weapons in less space.

Hypersonic Strike

Flying faster than a mile a second, facing scorching 2,000°F temperatures, all while maneuvering throughout flight, hypersonic missiles test the limits of possible.

We’re at the forefront of innovation, tackling seemingly impossible challenges to help create new classes of strategically important propulsion systems for our nation. With industry leading ramjets, scramjets and boosters, advanced materials, and full life-cycle development, we are leading the way for faster, more survivable, highly capable hypersonic weapons.

Facilities and Investments

To usher in a new era of military readiness, Northrop Grumman opened its Hypersonics Capability Center in Elkton, MD. Holistically designed to provide full lifecycle production, from design and development to production and integration for hypersonic propulsion systems, Northrop Grumman is defining possible to meet the Hypersonic Challenge.

Hypersonic Boost Glide Propulsion

Hypersonic boost glide propulsion vehicles briefly exit and reenter the atmosphere, then glide and maneuver at hypersonic speeds to their targets – a combination that makes them extremely difficult to track and very effective as fast-attack weapons.

Fuzes and Warheads

Building on our expertise as the only company to integrate both fuzes and warheads, Northrop Grumman’s warhead system is efficiently designed in a smaller package to support extended range and speed of the propulsion system.
