The A-10 is called the modern day 'Tank Buster'.
The
A-10 was literally designed around the 30 mm Gatling gun. The whole airplane "just fits" - the nosewheel is offset 280 mm to starboard to clear the gun barrel assembly. During the prototype phase, I met
Alexander Kartveli who was in semi-retirement from Republic; He said it was the ugliest airplane he ever worked on, but acknowledged it was very efficient as a gun mount.
