Northrop Grumman Technical Services has been awarded a $17.5 million delivery order to a previously awarded U.S. Air Force contract for four engine overhauls in support of the KC-10 program.

Work will be performed in Vancouver, Canada. It is expected to be completed by April 2018.

The KC-10 extender is a tanker capable of conducting aerial refueling. It can also carry cargo and refuel aircraft while transporting personnel or equipment.

It is also able to move medical patients using support pallets during evacuations.
