The chain gun on an A-10 Thunderbolt (aka Warthog) files about 3900 rounds
per minute. Another way to say it: $24,375 per second of depleted
uranium rounds. But don't hold the trigger for more than 18 seconds
because the barrel will melt.

They don't use depleted uranium, anymore. Tungsten is now the ammo of
choice.
