Phantom Express (XS-P, XS-1)

Phantom Express (XS-1) [Boeing]

Phantom Express (XS-P) is a Boeing designed reusable space place built for the XS-1 (later renamed XS-P for Experimental Spaceplane Program) program of the Defense Advanced Research Projects Agency (DARPA).

XS-1 is aiming for a recurring cost of as little as $5 USD million per flight.

The Phantom Express consists of a 30.5 m long vertical takeoff horizontal landing space plane powered by a single AR-22 reusable cryogenic rocket engine built by Aerojet Rocketdyne based on the legacy Space Shuttle Main Engine (SSME, RS-25) and an expendable upper stage. AR-22 was assembled from left-over and spare parts from the Shuttle engines, combined with new controllers.

Phantom Exoress is designed to take a 1361 kg payload into low earth orbit. 12 to 15 flight tests in 2020 are envisioned, culminating in a ten-launches-in-ten-days campaign. A launch site has not yet finally determined, with Cape Canaveral LC-16 or LC-20 being contenders.

In July 2018, the AR-22 engine was fired on a test stand ten times in ten days.

On 22 January 2020 Boeing announced, that they were ending their role in the Experimental Spaceplane (XSP) program immediately.
