Raytheon, an RTX (NYSE:RTX) business, in collaboration with Northrop Grumman, has been awarded a phase two contract from the Defense Advanced Research Projects Agency (DARPA) Burn n' Go program to continue the development of a new solid rocket motor (SRM) design. This new capability will decouple post-manufactured motors from traditional, single-use designs, enabling a composable motor capable of meeting multiple mission needs by adjusting thrust on demand.
