Northrop Grumman Wins $866 Million Radar Sensor Modification Contract

Northrop Grumman has been awarded $866 million contract for the sustainment and modification of radar sensors, providing depot-level sustainment services and modification projects for the Ballistic Missile Early Warning systems and PAVE Phased Array Warning system radars, and the Parameter Acquisition Radar Attack Characterization system.

Work is expected to be complete by May 31, 2023, the US department of defense said in a statement Friday.

AN/FPS-115 “Pave Paws” is a long-range UHF Early Warning Radar for Sea-launched Launched Ballistic Missile (SLBM) detection and warning and satellite tracking system. It is a solid-state active aperture phased array radar that was built for the Electronic Systems 

Pave Paws consists of a pair of circular planar phased-arrays about 30 m in diameter. The arrays are inclined from the vertical by 20º and mounted in adjacent sides of a building measuring about 32 m high, forming sloping walls on the seaward side of the structure. Combined coverage of the electronic beams of the two arrays is 85º in elevation and 240º in azimuth, according to radartutorial.eu.
