 This begins a year-long flight test program of about 100 flight-hours to expand the flight envelope to meet Sikorsky's key targets of 220-knot cruise speed carrying weapons, hover at 6,000 feet on a 95F day and 3g maneuverability at speed.Toward the end of Phase 1 testing, software will be upgraded to Block 2, bringing in the propulsor and articulating tail to increase speed and enable the full flight envelope.The second prototype (P2) was displayed to the public in October 2015.
