Harris Corp. has been awarded a $54 million U.S. Air Force contract for engineering work on the AN/ALQ-172 aircraft countermeasure system.

The cost-plus-fixed fee contract will cover engineering services applicable to the AN/ALQ-172 Line Replaceable Unit-1 countermeasures receiver.

It also calls for non-recurring engineering services for the form, fit and function interface, as well as redesign, development of data, manufacturing and delivery of prototypes that will meet legacy specification requirements.

Work will be performed in New Jersey. The estimated completion date is September 2020.

The Air Force Sustainment Center is the contracting activity.

The ALQ-172 has over the past decade defended B-52 bombers and C-130 aircraft against radio frequency threats in combat missions.

The system can simultaneously counter multiple pulse, continuous wave, pulse Doppler and mono-pulse threats.

It is integrated with the aircraft controls and displays to offer aircrews protection against sophisticated radar-directed threats.
