Washington, July 28 : The US Air Force’s massive 30,000lb bomb that is designed to destroy deeply buried bunkers that protect chemical, biological and nuclear weapons, is ‘ready to be used’.

The world''s largest conventional bomb, named Massive Ordnance Penetrator (MOP), can easily strike heavily fortified Iranian nuclear facilities.

Michael Donley, the US Air Force Secretary, said that the bomb ‘if it need to go today’, would be available.

“We continue to do testing on the bomb to refine its capabilities, and that is ongoing,” the Telegraph quoted Donley, as saying.

“We also have the capability to go with existing configuration today,” he added.

The 20 feet long, one feet wide weapon will be delivered by the B2 stealth bomber, the report said.

According to the paper, the new weapon is a critical piece of military hardware that underwrites American assurances to Israel that it will neutralise Iran''s nuclear facilities if diplomacy and sanctions fail. (ANI)
