WASHINGTON (AP) - The Pentagon is speeding up delivery of the largest non-nuclear bomb in the U.S. arsenal.
The colossal bomb is designed to destroy hidden weapons bunkers buried underground and shielded by 10,000 pounds of reinforced concrete.
The 15-ton behemoth - called the "massive ordnance penetrator," or MOP - will carry 5,300 pounds of explosives. The bomb is about 10 times more powerful than the weapon it is designed to replace.
Officials say the bomb, to be used in the B-2 Stealth bomber, could be fielded as soon as next summer.
Pentagon officials acknowledge that the new bomb is intended to blow up fortified sites like those used by Iran and North Korea for their nuclear programs, but they deny there is a specific target in mind.
