VF-01[1] was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity that took place on 22 February 2019, piloted by David Mackay and co-piloted by Mike Masucci.

It was operated by Virgin Galactic, a private company led by Richard Branson that intends to conduct space tourism flights in the future.

Following VSS Unity VP-03, VF-01 was a demonstration of the craft's ability to carry passengers.

Virgin Galactic's chief astronaut trainer Beth Moses acted as a test passenger, evaluating the experience for potential customers.

On 22 February 2019, Unity's mother ship VMS Eve carried it into flight in a parasite configuration.
