Lasguns = 20mm cannon?!?

Nearly all the fluff describes them as being able to blow a "fist sized chunk out of a man". The Word Bearer books speak of them "blowing the side of a man head off" Basically they're the m1 of teh dark future.
Are you nuts? A Lasgun uses a laser to superheat the point of impact, thus gassifing things like stone and armor, and making flesh (like watery Human skin and muscle) pop in violent blasts. Lasguns have little stopping power, if any, and will most likely not do much against heat-resistant things like Drop Pod armor or Ceramite.

Dunno about 20 mil. I've heard that .50 BMG is very much capable tearing chunks out of a body and dismembering limbs as well. As for performance against concrete, you could probably dig through 3 metres using a couple dozen armour-piercing rounds.

If you're lucky with a .50 you might take off a limb, but their effectiveness is insanely overstated by people trying to ban .50 cal rifles. Regardless, every weapon in 40k is as powerful as the fluff requires it to be; sometimes a lasgun will blow holes in people, sometimes burn holes through people, and sometimes do nothing at all. Should be noted that a 'realistic' laser would actually deal about ten times more damage to armour than flesh since flesh is mostly water (10 times the specific heat capacity of steel, yo) so the lasgun described in the fluff above would probably be able to disable a tank in one shot.

  • Or sometimes it burn finger size holes in people...
I'm aware of some aspects of firearms ballistics in that projectiles can either pencil straight through tissue or yaw and tear into flesh for far greater wounding capability. That being said, it wouldn't really be accurate to describe it as a 20 mil round either, and the variations in effect could very well be attributed to the lasgun suffering from variations in actual effectiveness, much like regular firearms.
So would it be better to make mention of this rather than straight-out comparing it to a 20mil autocannon? Like actually trying to table the effects in some way and extrapolating conclusions based on the lasgun's condition (firing mode, power) and the type of surface it is impacting (starship bulkhead, fleshy heretic)? Unlike other weapons, it seems as if lasguns have highly variable effects in even normal modes of operation.
Naw, that's getting too much into writing spackle. We know why, it's because the GW writers don't have a specific "lasgun do this" checklist and tend to have them as powerful as the current storyline requires them to be. The ridiculous variation is largely because guardsmen in stories can vary from HERO OF THE IMPERIUM! to nid fodder. Tim 12:59, 3 March 2012 (UTC)

Uhhh... I think we could have a wiki page for the Sniper Rifle, do you? -

Recharging a lasgun in a fire or via sunlight seems really, really stupid to me. Think about the amount of energy contained in your average campfire. Think about the amount of energy transmitted by the sun on a small patch of ground. Now think about the amount of energy required to instantly flash-boil just about anything in your way, and you'll see that it should be impossible to recharge a lasgun that way. --Bjorn (talk) 22:04, 30 August 2013 (UTC)

@Bjorn (talk) This is apparently fascinating to me that you don't seem to understand the concept of a store of energy. The average energy of a campfire is apparently enough to produce a fire of around 400 degrees, and sustain it for several hours. If indeed a lasgun battery is able to take heat energy and convert it into electrical energy, you can literally imagine it as storing said 400 degrees of heat inside of a considerably longer lasting source, and then building it up. I shouldn't need to point out that this game takes place in the year FOURTY THOUSAND, so it would be a real fucking leap to insist that electrical storage tech hasn't advanced anywhere past the year 2005 in over thirty eight thousand years. Nevermind that said same exact setting also has biologically immortal seven foot tall demigods, and demons that can consume planets. "YEA, IN THE GRIM DARKNESS OF THE FAR FUTURE, BATTERIES AND TEGs AREN'T REAL". No, the heat produced by a fire over the course of a second isn't enough to flash-boil someone's liver, but if you store the energy released by a fire over the course of an hour, then FUCK YEA it'll flash boil all the livers your heart can handle.

You can also "Flash boil" water at anywhere above 216 degrees at sea level, and 76 degrees in a goddamn vacuum. It wouldn't be a stretch to assume that you can flash-boil someone's liver at 400 degrees, if said energy was all imparted into a single pin-prick.Evilexecutive (talk) 05:22, 8 October 2015 (UTC)

Fallacy or not, strike throughs, unless part of a joke as in the Dark Angels page, are considered poor edit form, and little more than a passive aggressive edit war. If you don't like the paragraph, simply delete it.--Asorel (talk) 16:44, 7 October 2015 (UTC)

Lasgun stopping power and penetration issue[edit]

Quote: "the Lasgun has a AP of only -"

Don't really get why the AP- (AP0) gets harped on so often. Crunch-wise, AP- don't mean that you can't penetrate armour. It just affects on probability of the weapon penetrating specific armour. Again, crunch-wise, "humble lasgun" packs enough penetration power

  • according to 7-th edition - to have a chance to punch through rather heavy armour like space marine's power armour (1/3 probability of penetration), XV-8 Crysis battlesuit (again, 1/3 probability of penetration) or even such things like terminator armour or mighty Stormsurge battle-mech (both with 1/6 probability)
  • according to 8-th edition - to have a chance to punch through even the armour of Leman Russ battle tank or Tau Empire's Hammerhead gunship

Fluff-wise, well, lasgun shots are generally described as having penetration roughly equivalent to modern 7,62mm AK-47 bullets. That said - lasgun beams on standard power setting would not penetrate Space Marine's power armour's rigid (armoured ceramite) bits (however the impacts against Chaos space marines' power armour are known to score deep groves in ceramite plates) and would only scratch the paint on terminator armour, but it could reliably punch throught flak armour (or its equivalents), provided the shots connect with the target not at a bad angle or are not from very far away, and if shot withing 100 meters of target have a decent chance of punching through even carapace armour. --Terran Ghost (talk) 16:15, 10 June 2017 (UTC)

  • One more thing worth noting.

Quote: "A Bolter's bolts, on the other hand, penetrate the exterior and then explode inside the target"
a bolter round is basically 19.05mm (.75 caliber) mass-reactive shell with armour-piercing tip, that is accelerated up to 1000 m/sec once the rocket motor of the shell burns through. Essentially, that means bolter rounds is roughly on par with real life 20mm autocannon shells in terms of penetration. And that was for the "what were AP5 weapons meant to be capable of" (by comparison, .50 BMG equivalent was rated only AP6). That's why the lasgun, whose shots are meant to be on par with AK-47's bullets in terms of penetration was rated only AP-
Things get even interesting now, since both lasgun's and bolter's shots are now rated AP0 --Terran Ghost (talk) 11:03, 11 June 2017 (UTC)

    • Quote: "and that's not counting the fact that even carapace armour could be rather reliably pierced by lasgun's beams, abeit this would generally require a guardsman to close to about 100 meters distance to his target as opposed to lasgun's 400-500 meters effective range against infantry, donning only light flak vests and regular steel helmets" may be needing an explanation - this part came from Gaunt's ghosts novel series, where Guard-issue lasguns were effectively used at 500 meters distance against infantry, donning steel helmets and heavy-duty greatcoats, but carapace armored infantry was "within range" when they close to 100 meters. --Terran Ghost (talk) 12:38, 15 September 2017 (UTC)

Small comment but the section about anti-air capabilities reminds me of Call of Duty Black Ops III's Directed Energy Air Defense (DEAD) system which does exactly that. In-universe, high-powered mechanized infantry and ground machines saw a huge increased in use after DEAD systems started chewing up drones and air support like nobody's business. --Super12345 (talk) 21:44, 14 April 2018 (UTC)

Las AA[edit]

A way in which lascannons and flyers could exist in the same universe is if the las weapons have somewhat a limited range. This is kind of consistent with rules and fluff. How this is justified is another matter entirely. The "mechanicus cannot make proper optics" argument is stupid. But there might be something more to the las weapons. I mean, we know that lasers are heavily influenced by smoke, fog etc. Lasers in 40k seem not to be though. Maybe there's something in 40k laser technology that "clears a path" for the las beam, but this effect has somewhat a limited range. If a lascannon has, say, 5 km range, it's not the total flyers kill machine anymore. It still makes sense for interceptors and AA missiles to exist. But it does nothing to justify AA autocannons, lol. This is just an idea anyway Phas (talk) 18:03, 15 March 2019 (UTC)

About the Lascannons here[edit]

I'm toying with the idea of moving everything starting from the Corve Las-Pulser down to the Arachnus Storm Cannon to the Lascannon page since they're, well, cannons. And should we incorporate the Multilaser page to the Lascannon too while we're at it? That page isn't as big as the Laspistol's to warrant separation, no?

And speaking of the Laspistol, how about moving the Hotshot Laspistol and the Blast Pistol over there too since they're both pistols in size? Might also include the Digital Laser too.


I'm not really against it, but I don't think it's necessary since the Lascannon page only exists because of its size, same with Multilasers (which don't work like Lascannons) and Laspistols. -- Triacom (talk) 10:09, 22 September 2018 (UTC)
  • Agreeing with Triacom. The reason why the Laspistol, Multilaser and Lascannon has their own page is because they are fucking huge. So it is pointless to move the Corve Las-Pulser and Archnus Storm Cannon when the Lasgun already links the page to both Lascannon and Laspistol respectively. Furthermore, if you realize, there is some dubious fluff disputes between the Hellpistol and Hotshot Laspistol (Or the Hellweapon=/=Hotshot weapon in general); the Hotshot Laspistol already links to the Hellpistol's sub-category in the Hellgun page, so it would be extremely inconvenient if you move the Hotshot Laspistol to the Laspistol page as you would now have to click through two different pages if you want to get into the Hellpistol section specifically.

About the Laser Destroyers[edit]

So I looked up about this a bit more, and it seems that there are two variants of the Laser Destroyer Array. The first one is the common one like on the Rapier and on the Spartan. The second one is one with an additional rule on the Deimos Vindicator. This is not a topic I want to discuss.

The topic I want to discuss is the Laser Destroyer of the Destroyer Tank Hunter. It is a single cannon, which does not fit to the whole thing. I looked it up a bit more and it seems the weapon is called "Heavy Laser Destroyer," which seems to suggest that the weapon is a one big cannon using some system that gives it the power of four lascannons. I looked up further and guess the probable full name I found:

Heavy Laser Destroyer Array

Now this could be a typo on their part since I only found it on the list of its wargear, and its technical specification sheet omits the array part.

I honestly don't know, my best guess is forgeworld fucked up and forgot they already called something else a laser destroyer. -- Triacom (talk)
