Two demonstrator air vehicles are being built. The first was rolled out in December 2008. Flight testing is scheduled to begin in late 2009, carrier landings in 2011 and the programme will conclude in 2013. It will include catapult take-offs, arrested landings and flight in the immediate vicinity of the carrier.

The two UCAS aircraft will begin flying operations at Edwards air force base in mid 2010 and continue testing at the at Patuxent River Naval Base, from where it will fly to join a carrier air group at sea by summer 2012. Following the demonstration the program is expected to enter full scale development, toward full potential combat readiness by 2018.
