As many as six nuclear warheads, each with a destructive potential almost 10 times that of the Hiroshima bomb, were mistakenly flown across the US, Pentagon officials conceded yesterday.
The incident last week saw nuclear-armed cruise missiles mounted on the wings of a B-52 bomber and flown from an airbase 40 miles below the Canadian border to the southern state of Louisiana. The 1,500 mile journey from the Minot airbase in North Dakota to Barksdale in Louisiana lasted three and a half hours, during which time the crew were unaware of their nuclear load.
Pentagon officials said a munitions squadron commander had been relieved of his duties and crews involved with the mistaken load - including ground crew workers - have been temporarily "decertified" from handling munitions.
The director of air and space operations at US air combat command is to lead an investigation into how the plane was able to mistakenly fly nuclear weapons without anybody realising.
The cruise missiles were being transferred to Louisiana for decommissioning, as part of a programme to retire 400 of them. Three air force officers who spoke to the Military Times newspaper said the nuclear warheads should have been removed before the missiles were loaded under the bomber's wings. It is unclear why they were not. The W80-1 warheads have an explosive yield of 150 kilotons. The Hiroshima bomb is calculated to have had an explosive yield of 16 kilotons.

The missiles were not armed and safety features in the warheads would have prevented a nuclear detonation in the event of a crash, according to military officials.
