General Dynamics GAU-19/B Gatling gun

So you can’t be bothered with the whole man packing thing and just want maximum firepower / ammunition wastage (depending on your viewpoint) in a Jeremy Clarkson ‘power’ fashion, then this is the badger for you

Datasheet here

Gatling type rotary barrel weapons have never really caught on in the ground role because, I guess, the massive rate of fire means any unit using them would need a logistics convoy behind them loaded with ammunition but one aspect of this that has never really been explored is their psychological value.

The only place this type of weapon is in widespread use is on the widescreen, games and films always have this kind of weapon. Now laugh at me if you want but that translates into a widespread awareness that might provide a psychological advantage because, well, its looks well hard!

OK OK, back to Halo

Well the next time The Odeon’s Tora Bora multiplex is showing Terminator 2 it might have an effect, I suppose.

If that is indeed a Megabloks Halo Vehicle, you have some “Well ‘ard” Lego Men! Respect bro’…

Soooo, if it gets mounted on a helo, with probably less space, that has to lift the weight of all that ammo into the air, then whey the hell not mount these on Jackal 2 ? Just sayin…..

My 9 year old, who has only been “collecting” Megabloks HALO for the last 3 months immediately noted the Warthog seemed to be crewed by Lego people in “custom” garb !

Oh and if we are going to mount Gatling type weapons on RN ships, why mess with piddling 7.62mm and why not fit these babies ?

is it me or does the halo gunner fellow look a bit like an original series battlestar galactica pilot?

TD,

you get really crap and unpredictable beaten zones from multi-barrel weapons. You introduce several variables:

Barrel to barrel.

Barrel rotation speed increases with heat.

Barrel alignment to mounting increases in offset with heat.

So you start off with drilling a small area with hundreds of rounds (not very useful), and progress to spraying a large area with hundreds of rounds (more useful, but it gets tricky with ROE, and by then the enemy has his head down).

Firing a MG effectively is a bit of an art, not a science. Ranging bursts followed by killing bursts.

And as you say, a whole TA loggie regiment needed for ammunition porterage.

And who is going to clean the gas plugs? Bastard of a job. A GPMG gas plug after a day on the ranges takes a whole can of Coke and 30 minutes, Lord knows what three 0.50 gas plugs would take. I suspect the carbon deposits would keep a medium size power station going for a couple of days.

Now that you mention it elizzer…

Think it’s the brown helmet sidepiece. Though the top of the helmet needs to extend forward a bit for the old look. And a dark brown vest, not khaki.

“Lord knows what three 0.50 gas plugs would take.”
How many gas plugs does an electrically driven gun usually have, RT?

@elizzar and Observer – I think it is a re-equipped Lego Star Wars figure from an early range (Rebel Alliance with a pilot helmet)…and they must be tough little sods because the Halo Megabloks UNSC Marines they have taken the vehicle from are a good 50% taller, have fully articulated joints and are much more heavily equipped (sniper rifles, gatlings, chain guns, flame-throwers); Master Chief in particular is one tough SOB…trust me, I have a nine-year old.

Generally, the Halo range has some seriously cool kit…Warthog,Wolverine, Gausshog…although I think the Elephant mobile HQ/Logistic/Engineering AFV is a mite impractical, as is the Rhino six-track tank.

“Gatling type rotary barrel weapons have never really caught on in the ground role because, I guess, the massive rate of fire…”

Yanks will stick them on anything. The GAU19’s been carried on HUMVEEs for years. And the rate of fire of electric guns is whatever you want it to be – up to its maximum.
A HMG calibre with a GPMG rate of fire might be considered effective rather than excessive. There’s not necessarily a need to ramp up the rate of fire to 2000 rounds per minute for a turret gun or helicopter door gun. The higher rates of fire are probably more suited to fixed wing, forward firing aircraft than in other applications.

If an IED takes out your vehicle’s electrics, how do you fire an electrically driven weapon?

Also, if there’s a tactical reason to dismount, the batteries would be a bitch to carry…….

these are 7.62 cal ones but they show them on vehical mounts

http://www.youtube.com/user/DillonAeroInc/videos?flow=grid&view=0

they are lots of problems that you can come up with for any of the miniguns
from the power suppy to there excessive ammo use.
but they are intimidating and they are capable of providing sustained fire at a rate that nothing else can match and there are avalible in lots of different calibres.
For a weapon in a fixed position like a sanger or pillbox providing fire support they are ideal.
they seem to take an eternity to reload.

@ Brian Black,

good point, I hadn’t thought that one through. But I’ll bet they are still a bitch to clean. No such thing as a free lunch.

@ Ace Rimmer,

shoddy engineering (at least on British AFVs) will probably take out your electrically driven weapon well before any IED ever could. I call as witness the dog of a Spartan I once had. The extremely crude “RWS” was about the most pants piece of engineering that Alvis could possibly come up with. It NEVER bloody worked. They really must have sub-contracted it to the fellow who ran the corner shop.

He was probably also responsible for the flexible hessian tube that was meant to guide brass and link from the co-ax on Scimitar and Scorpion into a bin. Expended link and brass IMMEDIATELY jammed up in the thin neck of the tube, causing a stoppage, normally on your first ranging burst, which required the commander to get his head and body well into the turret to deal with it, at the most critical moment. So you ditch the tube, and then deal with link and brass cascading to the turret floor, much of it pretty quickly jamming up the turret race, so you lose your traverse, and can then only aim your co-ax and indeed main armament by telling Drives “left stick, left stick, steady, ON!” So you end up with a sandbag and a jubilee clip, but even that was not ideal.

@Red Trousers – Why would an externally powered weapon have a Gas Plug? :-)

No need. The .50 cal GAU 21, 1100rpm is good enough
