Wrong. It´s designed to pour a crapload of shots very quickly into the rough target area, making sure that enough hits are scored that the target is destroyed or severely damaged.
Compare with 30mm guns used by Apache and Tiger attack helicopters, the difference is BIG in accuracy despite the GAU8 using higher velocity ammo.
OFFICIAL accuracy of the GAU 8 is:"5mil, 80 percent
80% of rounds fired at 4,000ft hit within a 20ft radius"
(and even that includes a little hyperbole)
at just a bit over 1km, even if you totally ignore the 20% that is even further from the aimpoint.
1200 squarefeet area attack.
The problem with your perception here is probably that you compare it to the M61 that it is based on, which is even less accurate.
If they wanted a truly accurate gun, they wouldn´t have made it a rotary, as they are inherently less accurate due to barrels moving while firing. It takes high precision fire control and a VERY well stabilised mount like what is used on ground and naval anti air mounts to overcome this, and even then, it´s overcome by "walking" the line of fire onto the target using the fire control to track individual shells rather than calculating an intersect and firing at it. It works well(compared to other solutions) because modern jets are highspeed movers making a high rate of fire a need, but it also wastes a crapload of ammo.

Oh, they might survive(unlikely), but if you send a squadron against a Kirov, you´re going to have to be VERY lucky to cause any damage to the ship at all. Approaching in rough sea state at very low altitude MIGHT let you get a shot in before being seen and annihilated, but even that is going to need luck, especially when just the approch becomes as dangerous as trying to attack.
Give them AGM-65s so at least they don´t have to get in range of the PD systems and you get a much better chance.

Try it against a peer hostile navy TODAY and, well just forget about it, it´s suicidal.
Hell, even my own navy´s little corvette´s have a pretty fair chance of killing incoming aircraft long before they have a chance to fire a gun or drop a bomb at them. Modern sensors and modern fire control are just way too good for gun/bomb attacks to be viable against ships.
Sure, not impossible, but when even an old Tarantul corvette has 1 76mm gun and either 2 AK630 or 1 Kashtan gun/missile hybrid CIWS, seriously, trying to attack it with guns is just a very stupid game of chicken.
Because with modern firecontrol, even that 76mm gun can kill an A-10 every 3-4 shots, faaar beyond the range where the A-10 has any chance of hitting back, and an A-10 is an EASY target for those AK630s, remember, they´re made to be capable of intercepting SSMs travelling 2-6 times faster while being smaller.
Then you probably need to realise that while the A-10s protection scheme is awesome for an aircraft, it just means that instead of the 3-5 30mm shells needed to destroy an F-16, you might need 5-10.
It´s meant to protect against SMALL arms fire, machineguns, heavy machineguns and shrapnel(which is why it makes PD SAMs 30-40% less effective as well).
There´s excellent reason why the rest of the world moved to 20mm guns during WWII and to 23-30mm in the decades after.
USAs fanaticism about high rate of fire and high velocity, sure it´s useful, but that does not make it the best solution.

Compare with the GSh-301, the gun weighs roughly 1/6th of the GAU-8, it normally uses a firing rate around 1/3 that of the GAU-8, the ammo has about 15% slower V0.
But, if both guns fire 20 shots at 1200m, the GSh will put all shots within a 5ft radius(or less), while the GAU will put maybe 2-4 shots in the same center target area.
In fact, despite the lower muzzle velocity and slightly lighter ammo, the GSh is much more accurate at 1800m than the GAU is at 1200m.
The other common gun, BK-27 is almost as accurate as the GSh.
In short, no, the GAU-8 was most definitely NOT designed for accuracy. It is designed to spray areas.
