SpaceX will launch a secret spaceplane that Boeing has under development for the Air Force.
SpaceX’s test launch of the X-37B is set for August, according to testimony before the U.S. Senate Armed Services Committee on June 6.
“(The X-37B) will be going up again on top of a SpaceX launcher in August,” Air Force secretary Heather Wilson said at the hearing.
The X-37B — or Orbital Test Vehicle, as it sometimes is known — has made four previous orbital journeys. In those tests, the spaceplane was launched on top of a United Launch Alliance Atlas V rocket.
Little is known about the military’s planned uses for the X-37B, whose development has been kept tightly under wraps.
Hawthorne, Calif.-based SpaceX long has sought government contracts for military launches. A year ago, it was certified by the Air Force to launch military satellites.
