Yea...that's pretty much what an A-10 is... The GAU-8 gun fires depleted Uranium 30 mm Ammo at 3,900 rounds a minute (65 a second). The gun can generate 5 tons (!!) of rearward thrust , while the engines can only do 8 forward.
Essentially, the A-10 is built as one BIG gun. It’s cannon is over 19 feet long and weighs a massive 4,000 lbs. But hey, if it were any less powerful then it wouldn't be able to fire through steel tanks. Each missile contains depleted uranium,
