Question 1 of 9
Who designed the B-2 Stealth Bomber?
... Northrop (the company didn’t become Northrop Grumman until 1994) spent billions of dollars and nearly 10 years developing the top-secret project. The B-2’s maiden flight was on July 17, 1989
Question 2 of 9
The B-2 Stealth Bomber was one of the first military aircraft to be designed almost completely on a computer.
... Now it might not seem like a big deal, but in the 1980s it was a radical decision to design the B-2 on computer. Thanks to a huge computer network, engineers were able to verify their design decisions before the parts were even fabricated.
Question 3 of 9
Stealth Bomber is the most famous of the B-2’s nicknames, but what else is the jet sometimes called?
... Unlike most aircraft, the B-2 doesn’t have a tail and fuselage; the plane is just one giant, flying wing. This design is more efficient than a conventional plane, with the entire craft generating lift.
Question 4 of 9
The engine is the noisiest part of most aircraft. How does the B-2 minimize engine noise and keep itself stealthy?
... Having the B-2’s engine buried inside the plane doesn’t just reduce noise, it also dampens the plane’s infrared (heat) signature. In addition, all of the exhaust passes through cooling vents before flowing out of the rear ports.
Question 5 of 9
It’s a special kind of paint that helps keep the B-2 Stealth Bomber hidden from radar.
... You can’t buy it at Home Depot, but advanced radio-absorbent paint does keep the B-2 hidden from radar. After every flight, repair crews spend hours repainting the B-2.
Question 6 of 9
What was the B-2’s first combat mission?
... Ten years after her maiden flight, the B-2 Stealth Bomber saw combat in Operation Allied Force. The operation was not without problems. B-2s dropped bombs on the Chinese embassy; U.S. officials blamed the mistake on an old map, not the planes.
Question 7 of 9
The B-2 was involved with the longest combat sortie to date.
... The B-2 took off from Missouri, attacked targets in Afghanistan and landed on an island in the Indian Ocean. There was a crew change before the jet headed home, but the engines stayed running for a total mission time of a record 44 hours.
Question 8 of 9
How many working B-2s were built?
... There were 135 aircraft originally ordered, but the plane's ever expanding price tag and the end of the Cold War cut that order to 20. One of the test aircraft was refurbished to be combat ready – bringing the total up to 21.
Question 9 of 9
One of the engineers who worked on the B-2 was indicted for selling secrets about the aircraft to China.
... Noshir Gowadia was a leading engineer on the B-2’s propulsion system. He is also accused of helping China design and test crucial parts of a stealth cruise missile.
