Not waterproof but still useable in a vacum?[edit]

That doesn't seem possible, the article says it is not waterproof and then it says it has air for seven minutes of breathing in a vacum. Is that an inconsistency in the books or is this just wrong information? FatalSnipe117 01:08, July 3, 2010 (UTC)

Possibly. Or it's also possible that it's a semi-permiable suit, that it would allow stuff in (like water) but not out (like air).--Emblem 1.jpg Rusty - UserWiki:Rusty-112|112 ]]06:42, July 3, 2010 (UTC)
I'm guessing that the suit is waterproof, and that the fact that Tom and Lucy sank in their armour was because the equipment took heavy damage and has multiple leaks. But it's just a theory, so I'll leave it off the article for now. Arby116
Personally I think it's one of two things. Either A) The 7 minutes of air isn't for a vacuum, but rather for underwater. Or B) That because Tom and Lucy's Armor had already sustained plenty of damage, let water in. OniLink 01:48, 25 November 2010 (EST)


How much does this thing weigh? PX173 12:24, 24 July 2009 (UTC)


Could Marines use this armor? Does it amplify strength like Mjolnir armor does. I know it doesn't have shields or the power of Mjolnir. SPARTAN-101 15:02, 1 August 2007 (UTC)

  • Yeah, you don't need to be augmented to wear it. In fact, Alpha Company "washouts" who were never enhanced ended up serving as DIs for Beta Company and at least some wore SPI armor. -- 12:22, 16 July 2016 (EDT)Tex the Spartan

Strength & capabilities of SPI Armor[edit]

Yes the SPI Armor enhances strength, speed, and agility but not to the same point as MJOLNIR Armor dose. So while a Spartan-II in MJOLNIR Armor could lift a Warthog over their head or rip open a reinforced metal door like it was made of paper, as demonstated in the beginning of Ghosts of Onyx, SPI Armor would enhance a Spartan-III's strength & speed to probally half that, on top of their augmentations. Most likely enough to lift and throw say a Elite, who would most likely weigh like 350-or-400 pounds, with ease and snap bones like twigs and dent metal with a single punch and dodge some weapons fire but not enough strength to say lift and flip a Warthog, at least not with out a assist from a team mate. Also 'Powered Armor' means armor that both protects a soldier from weapons fire and battle field hazards and ehances their physical attributes, at least that is how every form of powered armor works I have ever seen. I hope that explains some of the qustions here. User:ShadowedSpider 7:44 January 7, 2008

Where's your source that the SPI armour improves strength/agility at all? I've recently re-read Ghosts of Onyx and I couldn't find a single piece of evidence to support your conclusion. I've edited the page until you present proof/source. Baryon15 22:04, 30 April 2009 (UTC)

I think he's right. The armor is called Semi-POWERED Infiltration armor. Anyway, the augmentations alone would allow them to lift that much. Remember the Spartan-IIIs have basically the same augmentation as Spartan-IIs, the only difference was Gamma company's brain modifications. So if we look through Fall Of Reach we can see that "They can lift three times their body weight-- which, I might add, is almost double the norm due to their increased muscle density" Pg. 73 in FoR. Since the augmentation is similar, if not the same and you account for the Spartans young age they would be able to lift that much if not more. 17:06, 28 June 2009 (UTC)

i agree, the s-III'S augmentations would let them say, bend/tear/dent metal, as evidenced when tom b292 ripped oper his drop pod in pegasi delta, they could rip a turret off its mountings, snap bones like twigs and with great effort, flip a warthog and lift and throw an elite

CPO Mendez[edit]

I don't understand, if the drill instructors can use it why doesn't CPO Mendez use it during the sentienal raid on onyx?--The Chazz 23:21, 9 February 2007 (UTC) --Well thats really simple,CPO Mendez was in the watch tower during the time of attack,unable to get to the armor.--Mac10&Cheese 15:14, 22 March 2007 (UTC)


do there suits have shields? User:Kami-Sama

No. but they have active-camouflage, rendering them nearly invisible. Kora 'Morhekee 03:06, 23 April 2007 (UTC)


Added a link to, a freaking spectactular job at rendering the SPI armor from the book! (Solidus117)


Wouldn't the picture in the article be a Mk.2? It says unknown but when Kelly gets there, (the one in the Mjolnir mk IV) the S3's are beta compamy and they used Mk 2 SPi suits.


I know that most, if not all, of this info is true so I won't put up the "Disputed Facts" template, but this page could use really some sources for confirmation. -- File:Slizer.png|30px]] Captain Obvious"Thank you, Captain Obvious!"||My Obvious Observations 04:52, 27 May 2007 (UTC)

The Halo 3 feture of the SPI armor. Does this mean a Mark III for sheilds would make Mjolnir VI and SPI equals? SPI rocks!Spartans With SPI ROCK File:Bad_Ass_Spartan.JPG|20px]] 00:46, 31 May 2007 (UTC)


Will the SPI armor in halo 3 have shields??? It would be cool if it had active camo AND shields, but then EVERYONE would use it...Iloveenergyswords 04:17, 31 May 2007 (UTC)

A good idea, just have the shielding about the same as if you have a severe handicap on. Respect them Grunts, MouParasite of Halopedia|s]]e File:XtremeBoxer1.jpg|25px]] 04:05, 3 June 2007 (UTC)
It doesn't seem to be all SPI armour, just the helmet is the same. Anyway, armour customization allows you to mix and match parts of different variations of the MJOLNIR armour, so that could mean that there might be SPI armour pieces. like the helmet, or the Extra Vehicular Activity space-walk type mentioned in GoO, which might involve the completely dome shaped helmet with all gold visor?--Keyes 07:38, 11 June 2007 (UTC)

Infact if you look at the armor cutmization page. Bungie confirmed it at EVA 09:59, 6 July 2007 (UTC)

SPI armour wouldn't fit into Halo 3. The reason being is that all armour permutations in Halo 3 have no effect on gameplay. The SPI armour doesnt have shields, and has active camo, giving it an advantage, and disadvantage, over the other armour.Ryan926 03:33, 19 August 2007 (UTC)

What chest armor would look most like it? EVA has head and shoulders covered.--Kamikaze14 13:03, 8 January 2009 (UTC)

You probably couldn't replicate it. It's an entirely different armor, even the gloves and leggings are different. Just look at the cover GoO and you can the the entirely different gloves. Really only the EVA helmet is the MJOLNIR variant that has any real similarity. But the most similar to the chest? I'd say CQB. 16:49, 28 June 2009 (UTC)

Temwork Teamwork is bad?[edit]

Teamwork is listed as a disadvantage. Wouldnt this improve their performance.Dragonblaze-052 07:28, 25 July 2008 (UTC)

It says it requires more teamwork to defeat enemies, I'd say that's a bad thing. [User: Mr Spartan32] 13:36, 21 May 2009.

Well it's not necessarily a bad thing but it's saying that it would take more than one to complete tasks that a single Spartan-II could do in MJOLNIR. So say one Spartan-II could jump into a bunker and shoot down all the inhabitants. It's saying that it would likely take more Spartans-IIIs to do the same task. 16:49, 28 June 2009 (UTC)

Motion Sensor[edit]

Does it have one? PX173 13:18, October 12, 2009 (UTC)

No. -User:SoH/Sig

yes, it does acually, read the beginning of chapter 36Ghost mactavish 09:54, July 13, 2010 (UTC)


Diffenant Versions[edit]

Does SPI Armor have diffenant versions,like Mark IV,V,VI have?

Example: EOD, Commando, EVA, stuff like that.

YakovSidorov 03:17, September 27, 2010 (UTC)YakovSidorov

I'm sure they did, but is just never shown.

From Ghosts of Onyx, we know that there have been Mark I and II iterations. From the Headhunters motion comic, we also know that there are different variants of SPI, like MJOLNIR, illustrated particularly well here, though we don't know the names of each variant. -- Specops306 Autocrat Qur'a 'Morhek 03:50, 30 August 2011 (EDT)


On page 252 of Ghosts of Onyx Liutenant Kurt Ambrose jumps into a river and stays there for some time; when he emerges, he has no complaints about waterlogging in his suit. He was wearing SPI Mk.II at the time. Should we take off that bit about the suit being non-airtight and non-watertight? --Bruce2401 20:41, 14 May 2012 (EDT)

Color sketch of SPI Armor[edit]

Hey, I was just wondering, was this color sketch of the SPI Armor drawn by Isaac Hannaford? I'm led to believe so, since I remember seeing the cover of Halo: Ghosts on Onyx on his blog. I sent him a message requesting he somehow post a color sketch of the SPI Armor. But I don't know for sure. I don't know, maybe I just don't want to look stupid. Can anyone help me out here? Does anyone if Isaac Hannaford drew the color sketch of the SPI Armor? --Xamikaze330 (talk|contribs) 19:59, 27 October 2012 (EDT)Xamikaze330

According to my copy of Art of Halo 3, it was drawn by the McLees (Robt and Lorraine). — subtank 04:27, 28 October 2012 (EDT)
Damn. Now I look stupid. How can I ask them? Things are never as easy as I'd hoped. --Xamikaze330 (talk|contribs) 08:47, 28 October 2012 (EDT)Xamikaze330
I was kinda hoping that when I got my copy of Halo: The Great Journey: The Art of Building Worlds, that the book would have the color sketch of the SPI Armor. I was rather disappointed when it didn't. Whoever scanned it didn't do a very good job with the colors or made sure it wasn't "spotty". --Xamikaze330 (talk|contribs) 08:53, 28 October 2012 (EDT)Xamikaze330
I think now would be a good time to try to figure out a way to somehow scan the two pages of the full-blown SPI Armor from my Halo Encyclopedia, and try to do it without being forced to rip or cut out the pages. This will be quite an undertaking. But I pray I'll figure it out. About time I did anyway. --Xamikaze330 (talk|contribs) 14:13, 28 October 2012 (EDT)Xamikaze330
(reset indent) Or not. Part of the SPI Armor color sketch in the Halo Encyclopedia is cut off on the edges of the pages. Damn, there goes that plan. Well, I still could theoretically go through with it, or I could put in a interlibrary loan request for the book and use that. And not forgetting that someone else who already owns the book itself could just go and do it themselves using a high-resolution printer-scanner or somesuch. Hate that the book is out of print. Wish they'd start selling it again. --Xamikaze330 (talk|contribs) 14:24, 28 October 2012 (EDT)Xamikaze330
UPDATE: Not a problem anymore. Just managed to obtain a copy of this great book on for $67. Expect image updates soon! Or at least, I hope to update them all. --Xamikaze330 [Transmission|Commencing] 19:53, 13 September 2013 (EDT)Xamikaze330


Is there any information on what company manufactures the Semi-Powered Infiltration armor? I've read Ghosts of Onyx about three times I think, but I don't think I found any mention of a manufacturer. Maybe I missed it? Does anybody else have any information to offer? --Xamikaze330 [Transmission|Commencing] 11:50, 28 September 2013 (EDT)Xamikaze330

I'd imagine SPI is manufactured by the Materials Group, though I don't think it's ever been stated officially. --Our vengeance is at hand. Gravemind.svg (Talk to me.) 23:07, 28 September 2013 (EDT)
It would be nice if someone with contacts could find out that information and maybe get them to release it officially. Anyway, I was wondering, do we know if the SPI armor is still currently being fielded with the SPARTAN-IIIs? Or have they made the switch to the MJOLNIR GEN2 armor as well? --Xamikaze330 [Transmission|Commencing] 15:16, 11 November 2013 (EST)Xamikaze330
I recall Glasslands mentioning that the surviving Spartan IIs and IIIs were folded into the S-IVs. And since the GEN2 MJOLNIR is standard issue for the IVs, I see no reason to believe they aren't for the former S-IIIs as well. I don't think it's been stated yet, but it's pretty likely. -- Qura 'Morhek The Autocrat of Morheka 05:20, 14 November 2013 (EST)

"EVA-like variant"[edit]

I'd say it's more likely that the purported "EVA-like variant" just falls within line of standard artistic variety within the default SPI helmet, instead of being its own separate variant. It's not like every other source has depicted it exactly the same way. --Jugus (talk) 00:35, 13 January 2017 (EST)

Only the Headhunters and detachments (like NOBLE) ever seemed to kit themselves with non-standard SPI and MJOLNIR kit. I'd as well chalk this up to artistic liberties than an absolutely conscious decision to add flavor into the SPI mix. I'd wait until this is confirmed to move forward. Until then we could move it into the Trivia section, I reckon. Helianthus All right. Shoot!
I'd say keep it. On the same image the EVA-like variant is on. A normal SPI variant appears in its actual design(with a eagle design on its visor).-CIA391 (talk) 10:21, 13 January 2017 (EST)
The difference isn't all that drastic, though. By the same logic, the "normal" SPI helmet in the same piece (with the eagle symbol) is a "variant" because the base design lacks the sharp-edged ridges and the lower part of the visor is different. The "EVA-like variant" is actually in some ways closer to the base version, at least around the lower part of the visor. If we went that route, Olivia's suit in the Last Light cover could also be considered a different variant, as it has considerably different detailing, gaps in the chest armor, blockier edges, and pylons on the sides of the back similar to Mjolnir armor (which most depictions of SPI armor don't have). Not to mention the forearms, which are a little different in almost every depiction. My point being, if we consider that one helmet a variant, we might as well list every other appearance of SPI armor a distinct variant because there are always some artistic differences. --Jugus (talk) 10:38, 15 January 2017 (EST)

(Indent reset) But the fact that that image clearly shows two different variants on the same image, I cant simply ignore it.

Plus the EVA-like helmet lacks the vents on its front, something that all Mirage-class helmets have at least in any depiction. (Bar the Headhunters one, but they are kinda already known to be special.)

Maybe we should ask Grim or someone about this. xD I tbh would love clarification.-CIA391 (talk) 14:10, 15 January 2017 (EST)

If we want to get technical, the same piece actually shows three different "variants". The jumping Spartan's helmet is virtually identical to the original SPI concept with its bulbous and curved shape. Meanwhile, the foremost one clearly differs from this design with its sharper edges and leaner profile, as well as the lower part of the visor, which narrows down toward the chin similar to the ODST helmet. As such, I don't think the lack of vents alone is reason enough to justify calling it a variant. Most likely the artist simply didn't pay as much attention to it as the dead Spartan is a more of a background element. --Jugus (talk) 04:28, 17 January 2017 (EST)
I agree, I'd chalk it up as artistic license/error. Could be worth a mention in trivia though. --NightHammer(talk)(contribs) 22:48, 17 January 2017 (EST)
Well ultimately its up to you lot. I would've suggested adding the eagle variant as a unique version also, wouldnt be the first timde 343i made artistic license canon. But alas I admit defeat(unless I get proof from 343i or something heh). XD But regardless I have no better way of adding it in as trivia so I must leave it up to you lot.-CIA391 (talk) 23:20, 17 January 2017 (EST)
