Israel may have cut a deal to delay attacking Iran in Exchange for better bunker busters and refueling planes

Reuters Germany - The USA may provide Israel with more powerful bunker buster bombs and in air refueling planes in exchange for a delayed attach on Iran

Maariv - Diplomatic sources said that according to the package deal proposed by Obama and Netanyahu, Israel rejects the attack on Iran in exchange for bunker bombs and refueling planes. Western sources: Obama has presented Israel "almost red light" to attack.

The White House has denied that there is a deal for bunker buster bombs.

Better bunker busters and refueling planes would enable Israel to attack Iran's deep bunker in Furdow.




Boeing's 30,000-pound Massive Ordnance Penetrator (MOP), an ultra-large bunker buster for use on underground targets, with Iran routinely mentioned as its most likely intended destination, is a key element in the implicit U.S. threat to use force as a last resort against Iran's nuclear ambitions.

The Massive Ordnance Penetrator (MOP) GBU-57A/B is a U.S. Air Force massive, precision-guided, 30,000-pound (13,608 kg) "bunker buster" bomb. The Air Force now has revived delivery of 16 MOPs as of November 2011.

* Warhead: 5,300 pounds (2.4 metric tons) high explosive
* Penetration:

* 200 ft (61 m) of 5,000 psi (34 MPa) reinforced concrete
* 26 ft (7.9 m) of 10,000 psi (69 MPa) reinforced concrete
* 130 ft (40 m) of moderately hard rock

It is designed for delivery by B-2 Stealth bombers.

Would that weapon, delivered in a gouging combination with other precision-guided munitions, pulverize enough rock to reach down and destroy the uranium enrichment chamber sunk deep in a mountain at Fordow, Iran's best sheltered nuclear site?

Critics of Iran's nuclear program tend to agree that military action against Iran's nuclear work would be their last and worst option. Not only would this risk civilian casualties, but Iran would seek to retaliate against Western targets in the region, raising the risk of a regional war and risking global economic turmoil.

Once it had recovered it would probably decide unequivocally to pursue a nuclear bomb.

John Cochrane, a defense specialist at the London-based Exclusive Analyst risk consultancy, said he believed the bunker-busting MOP might make a difference. But he suggested Fordow was at the very limit of the bomb's capacities, which he said could reach down to a maximum of 60 meters.

"Repeated strikes by Tomahawk cruise missiles and MOP might be effective in penetrating the site, if it is not as deep as 80m but, even then, we question whether an attack would have the same level of assurance in terms of damage as strikes on other 'softer' sites," he told Reuters.

Cyber attack or physical assault by Special Forces may be the only attack options.

Doing it the hard way

In a November 2011 article in Israel's Tablet magazine, Columbia University's Long concluded that Israel had the ability to attack the Fordow site using 75 bunker busters, each delivering a smaller explosive charge of about 1,000 pounds. However, he said it would require an unprecedented level of precision.

Long's scenario sees Israeli jets having "to do things the hard way," delivering 75 bunker busters on a single point to burrow through the rock.

There were two principal challenges, he said.

First, the weapons themselves, dropped from miles away and thousands of feet in the air, had to arrive at very close to the same angle to create a pathway each subsequent weapon could follow, he wrote. "Otherwise much of the penetrating power of the bombs will be wasted."

The second unknown was the "spoil problem," where the sides of the pathway, destroyed by previous explosions, clog the pathway for subsequent bombs.

An Air Force Research Laboratory fact sheet says that a 2,000lb-class weapon with 5,000lb-class penetration capability could be available within three years from a (report in 2011).

"Future fighters will be able to deliver bunker-busting capabilities currently associated with the bomber fleet," the fact sheet says.
