Interesting that Boeing’s vehicle will be powered by an Aerojet Rocketdyne engine; Boeing had partnered with Blue Origin on XS-1 Phase 1.

Replying to @thehighfrontier
The DARPA release includes the 10 flights/10 days test requirement in phase 3.

From the video description:

"... an entirely new class of hypersonic aircraft ...

"DARPA Hard"  It ain't what it use to be.

Boeing, DARPA to base XS-1 spaceplane at Cape Canaveral

A reusable suborbital spaceplane the size of a business jet being developed by Boeing and the Defense Department’s research and development arm could be launching and landing at Cape Canaveral in 2020, officials said after the defense contractor won a competition last month to design and test the vehicle.

The Phantom Express booster stage would be powered by a single Aerojet Rocketdyne AR-22 engine, a version of the space shuttle main engine, burning liquid hydrogen and liquid oxygen propellants.

Boeing originally partnered with Blue Origin, the space company founded by Amazon.com’s Jeff Bezos, as an engine provider for the XS-1 program, but later switched to an Aerojet Rocketdyne engine, according to Cheryl Sampson, a Boeing spokesperson.

“We conducted trade studies with Blue Origin in the first phase of the program,” Sampson wrote in an email to Spaceflight Now. “Boeing selected the Aerojet Rocketdyne engine for this next phase as it offers a flight proven, reusable engine to meet the DARPA mission requirements.”

Aerojet Rocketdyne said it will provide two engines for the XS-1 program with “legacy shuttle flight experience to demonstrate reusability, a wide operating range and rapid turnarounds.”
