As if living in caves didn't present Islamotroglodytes like OBL with enough headaches, they are soon to be serenaded at their overhead doors with the Mother Of All Heavy Metal Band Props-
Ten tons or so of tungsten, depleted uranium, or tungsten carbide constitute the knocking end of this two part door opener of the rocket assisted, 6 m [20 feet] long Massive Ordnance Penetrator. The 15 ton weapon contains a three ton explosive charge and is designed to penetrate up to 60 meters/200 feet of ordinary rock or concrete,and bury 8 meters/25 feet into reinforced concrete or even granite.
As if that's not enough, in less time than it takes to sing 'Rock of ages,cleft for me' along may come a scarcely smaller projectile, to 'ladder down' further into the ground through the rubble disrupted by the first. Northrop Grumman is working with Boeing, and they say " New more lethal defeat options for Hard and Deeply Buried Targets (HDBTs) like the Massive Ordnance Penetrator, that can overwhelm target uncertainties, are being developed ."
"The Direct Strike Hard Target Weapon... will make use of the JDAM interface under development for the B-52 & B-2 aircraft.The warhead will be a 20,000 lb. penetrator with dense metal ballast...an accelerometer ...allows control of the detonation point by layer counting, distance or time...The fuze can distinguish between earth, concrete, rock and air.
Performance predictions against targets were analyzed... experience has shown that 2,000 lb. penetrators carrying 500 lbs. of high explosive are relatively ineffective against tunnels, even when skipped directly into the tunnel entrance. Instead... the munition must be on the order of 20 to 30 klb. to couple a sufficient amount of energy to the tunnel. Optimized penetrators of this size ... may also be suitable for housing a clean, low-yield nuclear weapon..."
Sounds like Pinky Bhutto's chance to indulge the taste for underground testing Pakistan's military developed in her absence. Unless of course, Turkey calls dibs first on the prototypes of this NATO bolockbuster to deal with P P K die-hards holed up in what Baghdad's Deputy Prime Minister has called "the Tora Bora of Iraq."
