Northrop Grumman to Demonstrate Faster, Simpler Way to Replace Obsolete Parts for B-2 Bombe

The U.S. Air Force will get a more affordable way to replace obsolete avionics on the B-2 stealth bomber under a contract awarded to Northrop Grumman Corporation.
The company will produce a functional replacement for a B-2 avionics box called the Audio Central Distribution Unit (ACDU). More significantly, the work will map out a smart, cost-effective way to address a growing threat to B-2 readiness: mission-essential parts that cannot be repaired or easily replaced.
An increasing number of LRUs on the jet face or will soon face obsolescence. In some cases, the company that produced an LRU is out of business or can no longer produce the unit. In other cases, the equipment required to test an LRU is no longer available.
The Common Processor concept is achieved by taking advantage of functional similarities among avionics LRUs on the B-2 today. Common hardware elements will be used in unique combinations to create different types of LRUs.
Northrop Grumman and the Air Force have identified 21 different current LRUs on the B-2 that could be replaced using the Common Processor. Each LRU has multiple copies on the jet.
