The U.S. Navy Airborne Strategic Command, Control, and Communications Program Office (PMA-271) purchased a retired Royal Air Force E-3D for $15 million that will be used as an E-6B Mercury pilot training aircraft. The program office had been looking to acquire a dedicated training aircraft for the fleet to take the strain off using the current mission-capable E-6 aircraft. Since the E-6’s inception over three decades ago, the Navy has looked for ways to train pilots and keep them up to date on the airframe. Those options have included leasing several different commercial aircraft as well as using the mission-capable aircraft.

“The training flights expose mission aircraft to significant wear-and-tear and impact their readiness and availability. This is a great chance to work with the United Kingdom and bring a much-needed aircraft to the fleet. This team has done a great job of moving quickly and capitalizing on this opportunity,” Scott said. “It’s a big win for the entire E-6 community,” said Capt. Adam Scott, PMA-271 program manager.

For the past several years, the program has been looking for a dedicated trainer and found one when the Royal Air Force decided to retire their fleet of E-3Ds. Both the E-3 and E-6 are militarized versions of the Boeing 707. When the funds became available in the National Defense Authorization Act for Fiscal Year 2021, the team moved fast. Members of the program office went to Louisiana at the end of February to inspect the condition of the aircraft as they moved closer to acquiring it. Once the aircraft comes to NAVAIR, a modification will begin with a goal to get it out to the fleet by October 2023.

The aircraft will help reduce an estimated 600 flight hours and 2,400 landings/cycles per year from the E-6 mission aircraft. The E-6B is a communications relay and strategic airborne command post aircraft. It provides survivable, reliable, and endurable airborne command, control and communications between the National Command Authority and U.S. strategic and non-strategic forces. PMA-271 provides products and services that meet E-6B and future aircraft operational requirements to enable survivable, endurable, and reliable airborne strategic command, control and communications.
