A couple of program updates that I wrote for Space.com in recent weeks:
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.
Birdzilla remains more zilla than bird. The plane is still under construction, but the company has yet to announce what rocket(s) it will use.
The most recent update I’ve heard through the grapevine is that much of the aircraft is assembled. That’s a good sign, but it could also mean that much of the interior work — which can take a long time — remains to be done.
Last year, the company said it were considering more than 70 different booster configurations, which means they were talking to everyone and anyone with a rocket, an engine or plans for them.
In July, I asked Chuck Beames whether Burt Rutan & Scaled has once again put the flying machine ahead of the rocket, as they did with SpaceShipTwo. He said no, and assured me that they would make an announcement about the booster(s) in the fall.
That time came and went. Officials now say that they expect to make a series of announcements in the coming future.
