Why the B-2 is Still a Hanger Queen

April 28, 2006: Only about seven of the U.S. Air Force's 21 B-2 bombers are ready to go at any time, and now, a combination of robots, sprayers and quality control are trying to double the readiness rate. But for a long time, the B-2 has been known as a "Hanger Queen" (an aircraft that spends too much time in the hanger for maintenance or repairs).

Two years ago, the U.S. Air Force introduced the use of robots to reduce the maintenance efforts required to keep their B-2 bombers flying. The B-2 uses a stealth (anti-radar) system that depends a lot on a smooth outer skin.

That, in turn, requires that the usual access panels and such on the B-2 must be covered with tape and special paste to make it all smooth. And after every flight, a lot of this tape and paste has to be touched up, either because of the result of flying, or because access panels had to be opened.

All this takes at lot of time, being one of the main reasons the B-2 required 25 man hours of maintenance for each hour in the air.continue..
