A US B-2 stealth bomber crashed Saturday at an Air Force base in Guam just after taking off, but both its pilots ejected to safety, the US Air Force said.

The B-2 bomber crashed at Andersen Air Force Base and both pilots, who have been evaluated by medical authorities, are in good condition, the Air Force said in a statement.

An Air Force spokeswoman said it was the first crash of a B-2 bomber, but did not give any details about the bomber's mission in Guam.

Investigations will be carried out on the accident.

The B-2 bomber, which costs about 1.2 billion US dollars, is among the most advanced warplanes of the US Air Force, each capable of carrying up to 20 2,000-pound (900 kg) satellite-guided bombs and having a range of 6,000 nautical miles (11,112 km) without refueling.
