Washington: The Pentagon has announced that a 14-tonne anti-refuge superbomb could be ready by 2010 and will cost US treasure about $88 million.
The six-metre device is part of a project called Massive Artillery. The bomb explodes only after penetrating over 60 metres at the place of the impact.
The Defence Department terms it the "mother of all bombs". They say it can be charged with 2,400 kilograms of explosives, two times more than the previous BLU-109 prototype tested in 2003.
