An A-10 Warthog is the ugliest airplane in the world. It is built around a rapid-fire 30mm cannon that fires depleted uranium shells. It flies low and slow, can loiter for hours, can take punishment, and is used primarily as a close air support aircraft. The Air Force brass hates them (not enough glitz) but the grunts on the ground love 'em.

It flies low and slow, can loiter for hours, can take punishment...

IIRC, the pilot's seating area is basically an armored tub (titanium alloy?).
The enemy grunts on the ground can throw up lots of small arms fire and
the pilot is still (relatively) safe...

I remember being in Reforger 78 and the A-10 wiped out my tank company 2 or 3 times. You don't hear them until they are overhead and by that time (if they are using live ammunition) you don't hear them anyway. They fire anti-tank missles, too.
