The VH-71 presidential helicopter replacement program marked another milestone last Saturday with the maiden flight of the second VH-71 production aircraft. The aircraft is scheduled to arrive at U.S. Naval Air Station Patuxent River, MD, later this month. The VH-71 program’s first production aircraft arrived at the Navy’s facility November 24, and is conducting ground vibration testing.

Five production and four test helicopters make up the program’s first phase, or Increment One. The Increment One helicopters provide more capability than the current fleet which is scheduled to begin phasing out of operational service at a rate of three per year beginning in 2017.

Of the four test aircraft, two are in flight testing with a joint testing team made up of Navy, Marine Corps and industry pilots. The other two are undergoing mission systems integration at Lockheed Martin’s facility in Owego, NY.
