Autocannons


Hyoukage

Recommended Posts

I've seen 'em in MechWarrior, and was disappointed...

I've seen 'em in Command and Conquer Generals: Zero Hour - ShockWave, and my attention was acquired...

I've seen 'em in Warhammer 40,000: Dawn of War, and was hooked.

 

I speak of autocannons. Massive, rotary weapons sending hundreds of rounds per minute downstream. Large, .75 caliber quad-barrel weapons whose cumulative recoil has you going backwards without stepping. Smaller, .50 caliber 6-barrel weapons, capable of downing aircraft to the tune of 50 kills a minute. And, still smaller, 10mm 8-barrel weapons capable of sending near-solid beams of lead downwind to all but vaporize all but the most armored of targets.

 

These are what we need. Weapons capable of room-clearance in moments, not minutes. Weapons, whose mere presence would send Deathclaws screaming like terrified children. Whose spin-up would have even the most violent of Super Mutant wetting themselves in fear. Whose firepower would send entire armies running for their homelands.

 

Their ammo consumption is ridiculous, their spread is low, their damage is insane, their maintenance fees are extreme, and they are heavy.

But, in the end, you look back, and know this much: That 30 seconds of warfare, is something nobody who survived, will ever forget...

May be a 600rpm 30mm autocannon, but it has miserable ballistics over ranges longer than 1,000m...

I would recommend something with greater accuracy, let's see what's available, hm?

 

Here we go! The British GIAT-30M series autocannon!

 

http://en.wikipedia.org/wiki/GIAT_30

 

The 30M-781 uses the 30x113mm shell, and the 30M-791 uses the 30x150mm shell.

Both variants are capable of as much as 2500rpm with a more acceptable muzzle velocity of 1,025m/s, versus the MK 108 at 540m/s and 600rpm...

 

As for rotary designs I'd love to see?

 

Gryazev-Shipunov GSh-6-23 - A 23mm 6-barrel rotary, capable of up to 10,000rpm, at a rather slow 715m/s muzzle velocity.

http://en.wikipedia.org/wiki/GSh-6-23

 

A good design, and not-quite easily portable. A hefty 73-76kg (161-167lbs), plus more for ammo. A nasty not-so-little number.

 

But this one, puts it to shame...

 

http://en.wikipedia.org/wiki/GAU-8

 

The GAU-8 Avenger, as mounted by the A-10 "Warthog" anti-tank fighter. Firing the 30x173mm anti-armor high-explosive incendiary round to the tune of 4200rpm.

Muzzle velocity is 1,070m/s and an effective range of 1,220m... maximum range is over 3,660m. This 7-barrel rotary is noted for making up a considerable amount of an A-10's forward weight, so the tail has to be jacked to prevent the aircraft from tipping should the GAU-8 be removed.

 

This piece is no lightweight weighing in at 281kg (619.5lbs), plus more for ammunition. And considering the ammunition weighs in at 0.69kg (1.53lbs) or more per round... a belt of 10,000 rounds would be frigging heavy.
