The nation’s fleet of B-2 stealth bombers will all receive a new Northrop Grumman Corp.-developed radar system following the US Air Force’s decision to authorize full-rate production of the units by the company’s Radar Modernization Program (RMP). The decision, made by the assistant Secretary of the Air Force for Acquisition (acting), allows Northrop Grumman to begin fabrication of the balance of radar units needed to outfit the entire fleet. Those units will be produced as the final installment of the $468 M RMP contract awarded to the company by the Air Force in December 2008.

Northrop Grumman is the Air Force’s prime contractor for the B-2, the flagship of the nation’s long range arsenal, and one of the most survivable aircraft in the world.

“Putting this new radar on America’s flight line helps ensure that the B-2 fleet is ready day or night to protect the nation’s interests worldwide,” said Dave Mazur, Vice President and B-2 Program Manager for Northrop Grumman. “The new radar also makes it easier for our modernization team to add additional mission capabilities to the jet in the future.”

Northrop Grumman is currently producing radar units authorized under the RMP low rate initial production program, added Mazur. The company is also installing radar units in operational B-2s as part of the RMP system development and demonstration phase. The B-2 radar modernization program replaces the aircraft’s original radar system with one that incorporates technology improvements that have occurred since the B-2 was originally designed in the early 1980s. Raytheon Space & Airborne Systems, El Segundo, CA, developed the new radar hardware under contract to Northrop Grumman. The units include a new advanced electronically scanned array antenna, a power supply and a modified receiver/exciter.
