The problem with a GAU-8/A as a fighter gun is that the weapon and its
ammunition tank are so enormous that the plane has to be designed
around them, and they would use up a substantial part of the internal
volume of a fighter aircraft. Better to go with the Oerlikon KCA,
which fires equally powerful ammo in a much more compact package.

Much better to go with an M-61 variant that actually works, is combat proven,
and has a useful rate of fire.

Trouble is, this gets you back where the US was in 1950; the M3 .50" was
a superb gun in terms of reliability, ballistics and rate of fire and
was a thoroughly proven weapon. Trouble is, nobody convinced the MiG-15s
of that fact, so they soaked up a _lot_ of hits where a larger-calibre
weapon would have made the F-86 versus MiG-15 kill ratio even _more_
impressive.

And who out there is going to use significant numbers of unreliable, heavy, slow
cannon to oppose a US Force? The rate of fire of the .50 was not enough to
make up for the somewhat smaller calibre, that is not the case with the M-61.

Possibly, possibly not. The bigger the target is, the more damage you
have to inflict to down it. A MiG-15 weighed under 3,800 kg empty, a
Su-27 around 18,000 kg - nearly five times as much. A 20mm shell
weighs only just over twice as much as a .50 bullet. You can double
its effectiveness in recognition of the HEI content, but even so you
are still left with a pretty even match between the .5/MiG-15 and
20mm/Su-27 in terms of destructive effect compared with target weight.

Are you familiar with the concept of guided missiles? If you get into gun range
you have already screwed the pooch. The gun is a last ditch, desperation
weapon in ACM, wasting airframe volume and weight on a honking great,
slow, unreliable gun is not a wise trade off.

Yeah, a terrible tradeoff...right up to the point where you (or, more
accurately those you are supporting below who are locked in a very nasty
"knife" fight that precludes use of JDAM or an LGB) need it, as was found
during Anaconda.

The more things change, the more they remain the same. I've only
opined once in this long thread, but thought I'd jump in again after
this.

Some points:

1. The M-61, with roughly fifty years of experience is a reliable gun.
It's been modded and carried in a lot of different systems and made a
number of A/A kills.

A.) It doesn't jam. (It is possible, but it definitely isn't
common.)

B.) The the internal gun and several pod variants are linkless
feed. Some pods are link-fed.

C.) Spin-up time is virtually negligible. Consider that in the
F-105, the barrel in which the cartridge was sparked was still
internal, meaning the gun must rotate to the exposed barrel position
before the bullet leaves the barrel. Pass through of unfired rounds
on spin-up/down was usually counted as six. On scored strafe, the
rounds limiter was traditionally set at 150 round. With that, you
could get four or five strafe passes. A good shooter could score 80%
or higher out of rounds fired and every pass counted those six unfired
rounds. That means spin up is virtually instantaneous. Trigger squeeze
to release on strafe was taught to be .5 seconds. Good strafers could
get a shorter burst. Spin up is negligible.

D.) Projectile size/payload is important, but a trade-off.
Yes, a kill with a 37mm hit is more likely than a 20mm hit. But, if I
can't carry enough projectiles to give me a good density or chance to
hit, then the higher Pk is meaningless.

2. Dogfighting, meaning one-v-one maneuvering to a gun kill is a
foolish endeavor. You might wind up there, but you should studiously
avoid it. Once there, shoot and scoot. This isn't an airshow display
and no one but the survivor will recount the aeronautical skill
displayed. Shoot with missiles. Shoot at the maximum range. Get the
kill confirmed by AWACS.

3. The final insert by Brooks is irrelevant to the discussion. The
question has been about guns and air/air. The question of optimum CAS
weapon isn't trivial and my reply shouldn't be taken as one more
evidence of the AF aversion to support of ground troops. There is
NOTHING more important. But:

A.) First, support of ground troops involves keeping enemy
aircraft from being a player. We've done that successfully in every
conflict since WW II.

B.) CAS does not have to be fifty feet overhead with
snake/nape on "enemy in the wire". It can evolve to that scenario but
doesn't happen as often as common perception would think.

C.) Modern stand-off weapons provide equal or greater
accuracy than close-in laydown and without either jeopardizing the
delivery aircraft or warning the target to hunker down.

D.) While no one can put a value on the life of one American
soldier, a cost/benefit analysis of what strafe can do compared to the
risk involved usually mitigates against strafe being a primary tactic.
It's great for SAR and can be effective on close-in CAS, but it's
better done with an A-10 type system than an A/A optimized platform
(which was what the thread has been talking about.)

E.) While the guy on the ground may be firmly (and rightly)
convinced that his battle is the most important, the commanders must
allocate resources based on priorities which often don't have as much
emotion attached. Getting strafe to the troops in Anaconda wasn't a
readily available option.

F.) Good Forward Observers (FACs or AOs) should be calling
early for support. Good FOs should be GPS and Laser equipped and
getting the job done well before the more spectacular troops in the
wire scenario occurs. JDAMs et. al. are a much better choice. Bigger
payload, greater effect, better accuracy than strafe, more economical,
etc.

At least, those are some of my impressions on the argument.

In which case an M-61 works quite well.

Comments nearly identical to the one above were very popular in the
early 1960s. And then we got into a real shooting war, and pilots
suddenly needed guns again.

Yep, McNamara is still influencing military thought. I was sure we'd
gotten over that, but what goes around, comes around.

It's funny to hear someone call a gun "unreliable," since the failure
rate for modern aircraft guns is *miniscule*...

It's an interesting area to actually analyse, particularly when
comparing USAF and USN performance: in Linebacker the USAF shot down
forty-eight MiGs for twenty-four air-to-air losses, while the USN lost
four and scored 24 kills. More interesting yet, the Navy's fighters met
MiGs twenty-six times, for a .92 probability of killing a MiG and a .15
chance of losing one of their own; the USAF had eighty-two engagements,
for .58 kills per engagement but .29 losses.[1]

Sounds abstract? The services were using the same aircraft,
near-identical missiles (Sparrows and different models of Sidewinder),
but the USAF's F-4Ds and F-4Es had guns (pods for the Ds, internal for
the Es) supposedly as a solution to the problems encountered during
Rolling Thunder. Yet they were twice as likely to be shot down and
barely half as likely to kill, as the gunless Navy fighters. (Only seven
of the forty-eight USAF Linebacker kills were achieved with guns,
despite the efforts made to fit them)

Yep, McNamara is still influencing military thought. I was sure we'd
gotten over that, but what goes around, comes around.

"We're not training our crews properly, aren't using our weapons
correctly, and are employing poor tactics that make us very vulnerable"
is much less palatable than "the only problem is the aircraft imposed on
us doesn't have a gun!"

Note that the missiles have improved very significantly since 1972,
while the M61 - though a fine weapon -has had only incremental
modifications.
