It is possible that bunkers such as those in Iraq are buried under dozens of metres of rock. To break into something that deep you need a drilling effect. And that's the idea behind rapid-fire cannons such as "Deep Digger", being developed by Advanced Power Technologies.
The US Army has been breaking through concrete with cannon fire for years. An army manual states that it takes 20 rounds from a standard 25-millimetre cannon to make a breach in a brick wall large enough to walk through. It takes 25 rounds if the wall is made from 20-centimetre-thick concrete.
The idea behind APT's device is to concentrate the same number of rounds on digging a smaller hole, to make a tunnel wide enough to deliver a bomb through a metre of concrete. And APT's approach is far more effective than standard ammunition. As the missile approaches the target, it fires ahead rounds that split up on impact, breaking up an area several times greater than the diameter of the warhead. This efficiently reduces rock to fine gravel. The rear of the round contains blasting slurry, a type of semi-liquid explosive used in mining and quarrying. Moments after the shell's impact, the slurry spreads out to fill the cavity and then explodes, clearing away the debris.
This technology is being used to create a burrowing bomb. With several 25-millimetre gun barrels in the nose, it can blast its way down to the required depth before exploding. Its exact capabilities are highly classified, but according to an APT source it can already throw debris clear from a shaft 50 metres long, and may ultimately be capable of far greater depths.

Didn't they do something similar in "The Core"?
