WICHITA, Kan. (AP) — McConnell Air Force Base is celebrating the start of construction for its role as the main operating base for KC-46A air refueling tankers.

Several elected officials were scheduled to take part in Monday’s groundbreaking for the $219 million project at the Wichita installation.

McConnell officials say it will be the first active duty-led main operating base for the new aircraft.

Plans call for a two-bay corrosion control and fuel cell hangar, a three-bay general maintenance hangar, a one-bay general maintenance hangar and an aircraft parking apron.

U.S. Sens. Jerry Moran and Pat Roberts, congressman Mike Pompeo and various military officials were expected to speak at the ceremony.
