Naval Sea Systems Command (NAVSEA) awarded Raytheon [RTN] a $403 million modification on March 14 to produce three more Air and Missile Defense Radar (AMDR) low-rate initial production (LRIP) units.

These additional AMDR units, in an option exercised from an earlier contract award, will be deployed on Arleigh Burke-class DDG-51 Flight III ships.

The AMDR is the primary upgrade for the Flight III destroyers, featuring an AN/SPY-6 radar that is better able to detect and track ballistic missile threats.

Work will occur in Marlborough, Mass., and is expected to be finished by March 2023. The full award value was obligated at award time and will not expire at the end of this fiscal year.

Last April Raytheon won a $136.5 million modification for a single AMDR LRIP unit that will be finished by April 2021 (Defense Daily, April 20, 2018).

In October, Raytheon said the SPY-6 radar tracked multiple targets simultaneously and conducted its first track of a ballistic missile through intercept (Defense Daily, Oct. 10, 2018).

The first AMDR SPY-6 radar is being built at Raytheon’s Radar Development Facility in Andover, Mass., and is scheduled to be delivered for the first Flight III ship, the future USS Jack H. Lucas, later this year.
