Northrop Grumman, Firefly to replace Antares rocket’s Russian engines

Northrop Grumman’s Antares rocket is about to get an all-American upgrade with the help of Firefly Aerospace. 

The two U.S. space companies announced Monday (Aug. 8) they are working together to build a new first stage for Northrop Grumman’s Antares rocket while also developing a brand-new medium-lift booster for future launches. The partnership means Northrop Grumman will replace the current Antares rocket, which is built in Ukraine and powered by Russian engines, with a more powerful version (called the Antares 330) that can carry heavier payloads.
