Production Begins on New Radar for B-2 Bomber

PALMDALE, Calif: The nation’s fleet of B-2 stealth bombers will all receive a new Northrop Grumman Corporation-developed radar system following the U.S. Air Force’s decision to authorize full-rate production of the units by the company’s Radar Modernization Program (RMP).
The decision, made Oct. 16 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 million RMP contract awarded to the company by the Air Force in Dec. 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, Calif. 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.
The B-2 is the only U.S. aircraft that combines stealth, long range,
large payload and precision weapons in a single platform. In concert
with the Air Force’s air superiority fleet, which provides airspace
control, and the Air Force’s tanker fleet, which enables global
mobility, the B-2 helps ensure an effective U.S. response to threats
anywhere in the world. It can fly more than 6,000 nautical miles unrefueled and more than 10,000 nautical miles with just one aerial refueling, giving it the ability to reach any point on the globe within hours.
The 20-aircraft fleet of B-2s is operated by the 509th Bomb Wing from its headquarters at Whiteman AFB, Mo.
