Even the heaviest US bombs are not powerful enough to destroy some of Iran's more fortified nuclear facilities, the Wall Street Journal quoted US officials as saying Friday. The Pentagon is taking steps to improve its "bunker-busting" capabilities, they added.
US' 30,000-pound (13,600 kilo) "Mass Ordnance Penetrator" (MOP) was
specifically designed to be able to take out Iranian an North Korean
nuclear facilities. According to the report, initial tests indicated
that the bomb would be incapable of performing these tasks, either
because of the depth of facilities or their recent reinforcement.
said that the MOP's test failure prompted a secret funding request by
the Pentagon to Congress, seeking to enhance the bomb's capabilities.
The US Defense Department has already spent approximately $330 million
so far to develop about 20 of the bombs. The Pentagon is seeking an
additional $82 million for upgrading purposes, according to government
officials briefed on the plan.
