I understand that, as it is twice as dense as lead (for instance),
its kinetic energy is proportionately higher. Most airborne
anti-armour gun rounds rely on kinetic energy for penetration as it
is a simple and (normally) cost-effective solution. Consider that
the muzzle velocity of an A-10 GAU is increased by the delivery speed
of the aircraft (3,000 fps plus 600 fps I would estimate) so it must
make up about a sixth or a seventh of the total muzzle velocity.
However, the round apparently disintegrates at least partly on impact
with a hardened surface which causes the potential problem of
radioactive dust.

Since this thread is irretrievably OT, I've been tempted to ask this
question. I'm sure at least one of our resident experts will know the
answer: What's with this depleted uranium ammunition scare? Is DU used
solely because of its density - a way of making heavier projectiles
without having to make them wider or longer? Or is there some other
property that makes it particularly devastating against armour?
Just curious, regards
