The military’s next reusable space plane has gotten the go-ahead from the Defense Advanced Research Projects Agency and could be in flight tests by 2020.
The agency picked Boeing’s futuristic XS-1 for the tests, and it is being called the biggest revolution for military space programs since Redstone rockets took their first flights in the 1950s.
“The program aims to achieve a capability well out of reach today — launches to low Earth orbit in days, as compared to the months or years of preparation currently needed to get a single satellite on orbit,” the agency said in a news release.
The unmanned craft appears to be a beefier version of Boeing’s X-37B space plane, which also stemmed from a DARPA project. The X-37 program includes a vehicle that recently landed after two years in orbit. The craft carried an experimental thruster and a NASA test aboard, but Air Force brass have been mum as to the X-37’s other missions.
The XS-1, DARPA says, would be the size of a business jet and able to fly at 10 times the speed of sound. Boeing has named the craft “Phantom Express” and says it will be 100 feet long and 24 feet tall.
And unlike its smaller cousin, Phantom Express could launch itself to orbit without the Atlas booster used by the X-37.
Air Force Secretary Heather Wilson told The (Colorado Springs) Gazette last month that she’s pursuing new methods to get satellites into orbit quickly as the service focuses on what she fears will be a coming war that reaches orbit.
The military relies on satellites for communications, navigation, missile warning, targeting and intelligence.
If the Air Force’s satellites are hit, American troops on the ground could lose battles, Wilson and others worry.
The XS-1 could help ease those concerns.
