The inaugural launch had appeared to be going well until moments after the rocket was dropped from beneath the left wing of the jumbo jet dubbed Cosmic Girl.
"We've confirmed a clean release from the aircraft. However, the mission terminated shortly into the flight. Cosmic Girl and our flight crew are safe and returning to base," Virgin Orbit said in its official Twitter commentary on the launch.
There was no immediate word on what went wrong.
The highly modified jumbo jet took off from Mojave Air and Space Port in the desert north of Los Angeles and flew out just beyond the Channel Islands, where the drop occurred.
The rocket was supposed to fall for a few seconds before the first of its two stages ignited and hurtled it down the coast toward the South Pole for insertion of its demonstration payload into a low earth orbit.
The purpose of the flight was to gather data on every step of the launch process rather than to have a useful satellite in orbit; the demonstration payload was described as an inert mass and the intended orbit was very low to avoid contributing to the problem of space junk.
The launch attempt followed five years of development of the 21.3 metre-long LauncherOne rocket.
