Oh its a Boeing's 27mm Aircraft Cannon, based on the Mauser BK27. Where does it say its a licenced copy ? I missed that
The Mauser BK27 is a good design but its rate of fire cant touch the Vulcans 6,000 rpm it would take like 3 BK27s to do that since it was a rate of fire of about 1,700 rpm.
Interesting that they with a BK27 design seems to be a clear weight and space saver but you trade that off for Firepower. Guns may just be of less importance on the JSF

Second, the M61 Vulcan may have a theoretical rate of fire of 6000 rounds per minute, but it suffers from the usual speed-up time of Gatling guns - which can be more than a second with guns of this size.
M61 fires 70 rounds in the first second (6,000 rounds/minute = 100/second. 30% of the first second is waisted on winding up, so that leaves 70 rounds fired in the first second). The BK27 fires at 1,700 rpm, or 28 rounds per second. In order to fire the same amount of rounds in the first second, you'd still need 3 BK27's in stead of one Vulcan

The gun takes about 0.3 seconds to wind up to the full rate of fire, and half a second to wind down again. Not even close to more then a second

Not like the wind up rate even matters the BK 27 still cant come close to the rate of fire like I said

The GAU-12U also normally fires 3,600 rounds per minute, with a maximum of 4,200 rounds per minute.
The US choose a higher rate of fire and greater velocity over lower rate of fire and larger bullets. A tactic that has worked well for the US and these types of systems have also worked well and are battle proven.

'license copy' or 'based on' is not just semantics "Based on" can cover a large spectrum and can clearly not be a licensed copy.

I hadn't read that the gun had been dropped from the JSF. Is that all versions or just the US ones?

Pardon me if I am mistaken but you seem to be coming from a viewpoint of being unwilling to accept that the JSF (would have) used a foreign gun. Why would this be? The Mauser has been an excellent weapon on the Tornado for many years.

And only an idiot /goes to bed knowing he's going to be attacked/ with a gun in the nightstand or under the mattress. Because if he's damn lucky, he will here the threat coming through his bedroom door and then it's about sleepy reflexes.
Do you get the gun up? Do you get a shot off before he does? Does your shot kill him before his dying reflex does for you? Does _his friend_ kill you while you are cha-chucking?

Sigh. And a 7.62mm RPK round can end everything. Does that make it 'better' than either cannon?

REALITY CHECK PEOPLE. We have NO GUNSHIPS which are capable of delivering Vietnam style (helicopter or skyraider) direct support. Because every platform we own is so multimission screwed up /by cost/ (21 million dollar AH-1W) as to be supremely unwise to employ in that mission.

ShadowXIX,
And since you can't take a quote in context, why should I think you know better?

As such, the notion that you are going to fire BOTH AMRAAMs at a single opponent and then /continue to close/ for upwards of 20-30km to dance the dance with a gun is moronic. Because he doesn't have a stealth limit on his weapons carriage. Nor does his wingman. And you don't have 'no see'em' technology. You have _no see'em too good_ threshold limits upon detection. Continued closure will transit the point at which your are detectable and KILLABLE with heat missiles that themselves are 'imaging' sufficient to kill reliably from over 10km away.
A gun is a 1-1.5km weapon against aerial targets.
Stealth is an offensive tool. Provided you don't push it's limits, it gives you the power of dominant maneuver. Thus there is absolutely no point in believing a gun is transliterally a decent 'nightstand' weapon weapon because YOU are the thief.
And if you walk into a battlespace where you KNOW the enemy lurks, waiting. YOU ARE THE IDIOT.
Because "You brought the gun, I brought the missile, come on boy we're gonna cook you to a gristle."

GET IT? No I suppose not. Because after all, you're not a fighter pilot. You're thus not an idiot for thinking the weight of a gun is necessary on a 104 million dollar platform like the JSF.

Really, and how much do you know about daylight helicopter operations in Iraq? How about AfG where high adds to hot? How many AH-64 Apaches were lost in the first 30 minutes of Operation Anaconda sir?
How many helicopters have been downed in Iraq? How many missiles vs. guns vs. CFIT have been responsible for those losses?
I would 'hazard a guess' that I have /forgotten/ more about what is being hushed up over there than you ever knew.
And dumb as Americans are, they are /beginning/ to see how little monkey-presses-button necessary it is for them to pay a pilot what a cruise missile with landing gear could do as well or better.
CAN YOU READ WHAT IS SAY?
