One of the pilots of the B-2 stealth bomber that crashed Feb. 23 reported a fire at takeoff from Andersen Air Force Base, Guam, which was followed quickly by loss of control of the bomber, according to a senior Air Combat Command (ACC) official.
The stealth bomber rolled uncontrollably to the right and fell between the taxiway and the ramp at 10:45 a.m. Guam time just after passing the control tower. It was attempting a takeoff toward the seaward end of the runway. The two pilots ejected with one being hospitalized. A dark plume of smoke arose from the crash site and civilians outside the base reported a second explosion about 30 minutes after the initial impact.
The aircraft can lose one or even two of its four General Electric F118-GE-100 17,300-pound thrust engines and still take off, so it's unlikely that engine failure was to blame, says a retired U.S. Air Force pilot who has flown the B-2. Moreover, early suggestions that the aircraft struck birds or stalled in a steep takeoff climb also have been dismissed as unlikely. Also, the weather was reported as clear.
The bomber Spirit of Kansas, tail no. 890127, was the second in a four-aircraft flight that was ending its deployment and taking off for return to home base at Whiteman Air Force Base, Mo. They were being replaced by six B-52s as a forward-based, heavy-bomber force in the Pacific. The loss cuts the number of combat-coded B-2s to 15 from 16 out of the total force of 21. The force has a minimum aircraft requirement of 19 airframes.
The other three B-2s later returned to Whiteman, where the wing commander has declared a "safety pause" for the fleet, ACC officials say. During the pause, procedures are being reviewed with the pilots and training is at a standdown. However, if the stealthy bomber is needed for an operational mission it is cleared to fly.
The aircraft that crashed rolled off Northrop Grumman's line in 1989 and had accumulated 5,176 flying hours at the time of the crash. Early testing indicated that the aircraft would remain structurally intact for about 40,000 flying hours. Analyses also posited that the rudder attachment points would be the first structural failure item.
This is the first B-2 crash, but another of the Air Force's heavy bomber fleet, the B-1, has suffered a number of seemingly similar in-flight emergencies. A pelican-sized bird ripping through fuel and hydraulic lines downed the first, a fuel-fed fire on takeoff destroyed another, a fire in the instrument panel over Kentucky struck another and a fourth was abandoned by its crew about 100 miles short of Diego Garcia in the Indian Ocean while returning from a bombing mission in Afghanistan.
