Northrop Grumman upgrades Antares rocket

Northrop Grumman Corporation and Firefly Aerospace have joined forces to develop new version of the Antares rocket launch system and manufacture a new medium launch vehicle.

The original Antares rocket features a 3.9 m by 9.9-m high composite fairing made by Northrop Grumman. The company has also built other composite structures for the vehicle, including the combined fairing adapter, dodecagon, motor cone, and interstage.
“Through our collaboration, we will first develop a fully domestic version of our Antares rocket, the Antares 330, for Cygnus space station commercial resupply services, followed by an entirely new medium class launch vehicle,” said Scott Lehr, vice president and general manager, Northrop Grumman.
