WTF are u talking about dude??? The -262 didnt fly around with his engines at full throttle...Think of the Me 262. It was 100 mph faster than the P-51. In a dogfight, if there ever WAS one (which I doubt), the P-51 could not hit the Me 262 with enough rounds in a short burst to do significant damage before the plane was out of the line of sight. It took hits on the engines to slow the Messerschmitt down.
GregP said:Simple, we started replacing the 12.7 mm (50 cal) Browning when it was found that the speeds of aircraft were getting to the point where only a short burst could be expected to hit. Once taht happened, weight of fire per second was more important than rate of fire per second.
By the time we mounted 30 mm cannons, one hit in a vital area would disable a plane, if not shoot it down.
The A-10 shoots depleted Uranium rounds that have enough muzzle energy to penetrate a tank with one round.

As long as you have only a small chance of a hit, a more energetic round is indictaed.
