Talk:Magnetic Accelerator Cannon

I think the three metal plates under the Pillar Of Autumn could be its MAC canon, as described in Halo: The Fall of Reach --Climax Viod 10:56, 23 October 2006 (UTC)



What do you think ?


 * Yeah i think that looks right --Xeon 800--


 * I think you could be right.--Ryanngreenday 20:34, 23 October 2006 (UTC)


 * I agree, it most likley is. If it's not... what else could it be? - Knuxchao


 * Yeah I agree with it too, its the closest we've gotten to knowing where the MAC Gun is on the Pillar of Autumn, and it looks big enough for it to be a MAC gun too. User:Joshua 029

Should i add this to the MAC article ? --Climax Viod 15:27, 3 November 2006 (UTC)

Are you sure?

Thats what ive been saying --Climax Viod 14:46, 4 January 2007 (UTC)

Actualy after rethinking this i believe this to be wrong --Climax Viod 21:08, 14 January 2007 (UTC)

For anyone who still thinks the muzzle is at the three metal plates, check out the picture of the Marathon class: http://img134.imageshack.us/img134/8809/marathonclasscruiserae9.jpg

At first, you may say "The Marathon class has 3 MACs, and there are three distinct metal plated thingies. They must be the muzzles!" But look again. The third plating thingy near the stern would clearly have to shoot right through the second one, making it impossible that the metal plates represent the MAC muzzles. 74.113.238.25 05:56, 14 April 2007 (UTC)

i believe that either of the se woul be the place of the MAC b/c if you look how large the barrel is on the Super MACs, then this would have to be the location b/c the barrel would have to run almost the full length of the ship, b/c if it was at the bottom then it would be like firing a pistol at a blast door considering the amount of power that it would build up when in comparison to a MAC and a covvie cruiser, so it would need a much larger barrel e.g the 2 that are designated i would think it is the bottom of th e2 b/c it looks more barrel like and dark.(i suspect it is the same place on the marathons single MAC as there is no bottom part like the HAlcyons kk cheers,.......

Page 272 of Halo: The Fall of Reach says "Captain Keyes drifted toward the stern and noticed concealed and recessed 50mm autocannons for defense against single ships. Underneath were bumps-part of the linear accelerator system for the ships lone MAC gun." This implies the MAC to be somewhere around the underbelly. Also, the Super MAC is much longer that a regular MAC, being that a regular MAC is an underpowered Super MAC. A shipboard MAC does not single-shot a Covenant ship.

 * Actually, that quote means nothing at all. It doesn't imply that the MAC launch tube is in the underbelly of the PoA, all it says is that part of the acceleration system is located there. I have a lingering suspicion that the only reason ships are designed for a specific length is for the MAC launch tube. After all, why else would the UNSC make all its vessels bilaterally symmetrical and have a straight line from stern bow for placing a MAC tube in? 74.113.238.25 03:19, 12 April 2007 (UTC)

i know that, but it would still have to be of considerable size and if it were at the bottom the barrel would run through the centre of the ship in between the lifepods, yes. so it would have to have some sort of damage of them + with the engines bieng as big as they are i suspect a massive drive system for them located behind them so the actual length of the MAC if it was at the bottom would be around 150-400m which doesnt seam like enough room to fit a weapon that is suppose to be able to nuetralize a ships shealds or destroy a UNSC ship in 1, kk just a though thanks mate, J!MMY8806 14:42, 15 January 2007 (UTC)

The Pillar of Autumn uses Magentic Feild Recyclers and Booster Capacitors to fire 3 succive shots with one charge. It does not have 3 guns. Fall of Reach page 275. --UNSC AI 02:02, 15 January 2007 (UTC)

Question here
Super Macs are the best defense we have against the covenant... Instead of building all these non-essential weapons like the frigate... Why dont we make ships bigger than Marathon Cruisers that have the capabilities of having enough size to feature something like a Super-Mac Cannon. It's wierd... A fanfiction must be written on this! xD Later. CaptainAdamGraves 02:07, 15 January 2007 (UTC)

or even better. Put slipspace and regular engines on MAC platforms! :P --UNSC AI 02:09, 15 January 2007 (UTC)


 * This is exactly why I dont see this the way Halo is as being how realistically we would be in a balls to walls fight for humanity. Wouldn't we strive for the biggest and best shit possible? Like in world war II, because we became a militaristic based nation, we made the best things. If we become a militaristic race, wouldn't we be into crazy big things? And yes, I dont understand why the MAC-Stations are stationary, its stupid... Grrrr.... CaptainAdamGraves 03:11, 15 January 2007 (UTC)


 * Thing of it. putting a Super MAC on one huge ship may seem like a good idea, in theory. but what's the Covenant's first target going to be? they'd blow it out of space before it could even charge the MAC! which i would imagine would take a while! Frigates are smaller, faster, and cheaper to make, which is why they're still used at all.


 * I agree. Also, it would take years (and dont forget the money) to make just 1 of them as a ship. This would be due to the testing of a Slipspace drive powerfull to push an item, atleast over a mile in diamatre. If my calculations are correct, any slipspace engine able to push a super MAC to FTL, would instantly, or almst instantly be blown into subatomic particles. -- 21:45 19/01/07


 * Actually, you are wrong, and I daresay, talking out of your ass. How can you make "calculations" about technology which we have no theoretical concept about? Predict what happens through objects travelling through IMAGINARY dimensions using IMAGINARY technology that nobody really understands?. You can't. Besides, large objects are provably able to enter and travel through slipspace successfully: High Charity manages to do without "instantly be blown into subatomic particles." We have been shown no upper size limit on what can travel through slipspace. 74.113.238.25 03:23, 12 April 2007 (UTC)

The thing is MAC Stations use broadcast power to charge thier capacitors--UNSC AI 21:37, 19 January 2007 (UTC)

Well it seems the Super-MAC is superior to Covenant weapons so why not make the Super-MAC mobile like Slipspace engines so defending Super-Macs when all is lost can jump to another system like Earth if Reachs Macs woulkd have jumped would have had 320 Super-Macs


 * Frigates and Destroyers are essential to the UNSC fleet because they are fast an maneuverable. The MAC station could not avoid being a primary target. The smaller ships have MAC guns. -ED 19:13, 10 March 2007 (UTC)


 * Super-MAC's need ground-based generators, ferrying the energy needed to power the massively powerful MAC's, to operate. how would they carry them around with them? if they were made smaller, they'd take ages to recharge, and by then the enemy's plasma volley will have wiped them out. by far the best method is to stick to smaller, more manoeuvrable, cheaper ships rather than big, unwieldy things that would be obliterated. -- SpecOps306 07:12, 8 April 2007 (UTC)

Not railguns
The MAC isn't a railgun. It's actually a coilgun. There's a difference. I could explain it, but you could also look it up on Wikipedia.

The Name
Many people call this the MAC cannon. When MAC stands for Magnetic Accelerator Cannon, why do people add a "cannon" after it? They are technically calling it "the Magnetic Accelerator Cannon cannon". I could rant on about how they call it the MAC gun also, but I seem to have reached my point. -Blemo 02:50, 5 April 2007 (UTC)


 * It's like the La Brea Tar Pits, literally meaning "The The Tar Tar Pits." It's weird English stuff that doesn't make sense. -- Dragonc laws ( talk ) 05:09, 12 April 2007 (UTC)


 * Or an ATM Machine. (Automatic Teller Machine Machine.) Just go with it.

Numbers
I was looking at the page, and it says that the Super Magnetic Accelerator Cannon is "capable of accelerating a 3000 ton ferric-tungsten round to 40% the speed of light, or 179 875 474.8 kilometers/s (74,512.9 miles/s)." Since this is neither the correct number nor the correct magnitude, I thought that I should point it out. The speed of light is 299 792 458 meters/s or approximately 300 000 000 m/s. 40% of this number would be 120 000 000 m/s or 120 000 kilometers/s.

Odd. I was going through the Halo: Fall or Reach paperback, and on page 283, the Super MACs accelerated "three-thousand ton projectiles" to "point four-tenths the speed of light". I see that not as 0.4C, but as (0.4/10)C, or 0.04C. --Some Sci-Fi guy 6-27-2007


 * It could be useful if someone with the books or whatever could find the reference where it gives the muzzle speed of the 'standard' MAC (currently 0.1 c in the article). If the SMAC is 0.04 c then some very interesting things start happening once one plugs in the numbers.  Namely: the SMAC produces slightly less KE than the MAC, but about 2 times the momentum.  (That would imply something about Covenant shielding too, no?)  On the other hand, if it turns out the MAC is only, say, 0.01 c then everything works out to the original expectation (i.e. that the SMAC is heads and shoulders above the MAC in all ways.) 74.99.140.28 20:04, 27 June 2007 (UTC)

I would tend to think that it's actuall 0.01C, not 0.1C, since while a shipboard MAC is linked to the power systems that drive the ship (it has to share juice with sensors, propulsion, life support, etcetera) a Super MAC just sits there and blows the crap out of things. Of course, there's always the possibility that Nylund meant either "four tenths" or "point four", but seeing that he's a good writer and the books are pretty much error-free, I'm sticking with Nylund actually meaning .04C 75.61.142.8 00:23, 28 June 2007 (UTC)

Were did the shipboard MAC numbers come from? What page, of which book? The only thing that I remember from reading the books was that in “The Fall of Reach” page 107 “The MAC - Magnetic Acceleration Cannon - was the (ship’s) main weapon. It fired a super-dense ferric tungsten shell. The tremendous Mass and velocity of the projectile obliterated most ships on impact.” The exact weight and speed was never stated as far as I can remember.

AIMING !!!!
How the hell would you aim a MAC? you must have to turn the whole starship because the round travels the lengh of it, like an Bull-pub assault rifle -- Climax-Void   Chat  or  My Contributions

I was also wondering this, maybe it has small thursters kinda like the shuttles or the ISS use to keep in the proper orbit? I remember in Fall of Reach a part where the orbitals re-oriented themselves and blasted covie dropships heading for one of Reaches poles but it didnt say how they maneuvered. Oh and btw its bull-pup not bull-pub;)

In Fall of Reach, the ship that Keyes used before the Pillar had some king of emergency thursters, or something among those lines. So, I agree that the platforms may have some kind of thrusters to allow it to aim at enemy ships. About the ships... Well, basically, yes, you would have to manuever it to aim at the covenant ships. The lenght of the barrel has its problems, and the lack of a alternative in the aiming system reduces the tactical capabilities of the ships. Felix-157 17:51, 4 June 2007 (UTC)

3000 ton shell?
In Halo: the fall of Reach, the 20 orbital MAC guns that defended Reach fired 3000 ton uranium shells but Cairo station is an obital MAC gun and in the big room where the anti-matter bomb is, you see the uranium shells being loaded into the cannon but the shells are about as big as the Chief so how can they be 3000 tons?
