Future Weapons of War in the Works

Popular Science looks at weapons the military is developing for future wars including electromagnetic railguns, space darts, superfast torpedos, laser cannons, and a gun that fires a million rounds per minute."

  1. Who needs explosives indeed? by Motor · · Score: 5, Informative

    I remember during Gulf War II, the British were dropping bomb-shaped concrete blocks attached to the fanastic guidance systems they have now. No explosives needed... just plonk it down on a tank from 20000 feet and it does the job with much less collateral damage.

    Brilliant idea

  2. That's not strictly true... by Anonymous Coward · · Score: 5, Informative

    Look at tank ammunition:

    Discarding sabot - essentially a metal dart. This kills tanks using kinetic energy to punch a hole through armour. Makes a little hole and a lotta mess inside. This is the tank version of kinetic-only ammo, so scaling this up to use in a missile isn't a particularly new idea - the Durandural anti runway missile has a hardened nose cone and is rocket-accelerated under the concrete before it explodes.

    HESH - high explosive, squash head - hits the outside of the tank and explodes against it. This shakes scabs of metal away from the inside that fly around the cabin, killing the crew. This doesn't need to penetrate to destroy the ability of the tank to fight.

    HEAT - high explosive, anti-tank - this is the warhead attached to stuff like the RPG7. Nasty design - the shaped charge fires a jet of energy/molten metal through the skin of a tank, causing lots of damage inside to vehicle and crew. Even the relatively small warhead on a RPG7 can penetrate around a foot of steel.

    Now, the point for the last 2 shell types existing is that sometimes, kinetic energy isn't enough. Other ways to get better results are to make the shells heavier - using depleted uranium for example. While what I'm talking about here is tank warfare, the same will apply to bombs and bunker munitions - different tools for different tasks.
