"Although the A-10 can carry a considerable amount of munitions, its
primary built-in weapon is the 30×173 mm GAU-8/A Avenger autocannon.
One of the most powerful aircraft cannons ever flown, it fires large
depleted uranium armor-piercing shells. The GAU-8 is a hydraulically
driven seven-barrel rotary cannon designed specifically for the
anti-tank role with a high rate of fire. The cannon's original design
could be switched by the pilot to 2,100 or 4,200 rounds per minute;
this was later changed to a fixed rate of 3,900 rounds per minute. The
cannon takes about half a second to reach top speed, so 50 rounds are
fired during the first second, *65 or 70 rounds per second
thereafter*. "
At some point in its development, the "exhaust" from
the GAU was enough to cause an engine flameout in flight.

It is a crazy bit of kit.
Was it also fact that the plane was actually slowed ('measurably', I
know 'Every action has an equal and opposite reaction' so even a
single bullet fired forward would have an effect to a tiny degree))
when the gun was fired?
Yup, I believe so... Its not an aircraft with a large gun built in, its
a large gun with wings and an engine added!
