The merits of the 27 mm BK 27 revolver as opposed to the M61A1 can be
clearly demonstrated. In the first 0.5 seconds of firing, the M61
fires 18 rounds massing 1.8 kg in total weight of projectiles, the BK
27 fires 14 rounds weighing 3.7 kg. In the first full second, the M61
fires 68 rounds weighing 6.9 kg, the BK 27 fires 28 rounds weighing
7.4 kg. In weight of fire, as well as the destructiveness of the
individual projectiles, the Mauser clearly has an advantage, albeit
one that the faster-accelerating M61A2 reduces somewhat. This is
significant in that dogfights frequently permit only the briefest of
firing opportunities, and although a skilled pilot anticipating a
firing opportunity can 'spin up' a rotary in advance, such notice
cannot always be guaranteed.

This skips one of the big advantages of a faster-firing gun.

When your target is crossing your sights, having twice the "cycle time"
puts bullets into the other plane twice as often. Skeet shooters use
shotguns instead of rifles. Weight of fire is nice, but heavier bullets
don't help much if the other plane gets missed altogether due to not
having enough of them on target.

Note also that the Mauser install in the Typhoon holds about 1/3 of the
ammo that the M61A2 in the Raptor will, so things come out pretty even
as far as throw weight and firing time, with a small advantage for the
Mauser in promptness, and a small one the other way for the M61A2 in
overall bullet weight in the aircraft (eight one-second bursts versus
five for the Mauser).

Now, if you're shooting at tanks and other ground vehicles, that Mauser
sure has an advantage, but the F-22 probably won't be spending a lot of
time at that...

(The British Typhoons aren't even going to have guns in them after the
first tranche, BTW. Bad idea.)
