DARPA has received authorization to spend $146 million on the next phases of the program, which is enough to select one of the three companies and move forward. It’s not enough to finish the program, so the selected company will need to come up with funds of its own. DARPA hopes to down select by the end of the year.
Boeing, Masten Space Systems and Northrop Grumman are the leads for phase 1 of the program. However, phases 2 and 3 are open to all U.S. aerospace companies. DARPA had an industry day for the project on April 29.
