Much of the effect of a cannon is its hitting things. I could easily see a near-miss knocking someone around due to air-flow, but it is nothing compared to having a shell hit the ground in front of you. I think that the most important aspects of the cannon right now are
: Air angles: we need to be able to shoot at high angles to hit the enemy. You have this but it is not mentioned in your bullet-points or T.L.D.R. that I can find, which could cause it to be missed. but it is there which is good.
: Air coverage: single rounds do not do so much to a swarm of carpets or a ship that is kept aloft by numerous carpets and can probably survive losing a few. The latte r is less of an issue but some sort of air-burst proximity rounds or scatter-shot would be extremely helpful.
: Penetration: Their new ships are very scary, they can probably increase the armour without too much trouble, just by improving the efficiency of their carpets or adding shaped armour. Your design has smaller shots which could prove incapable of piercing the current generation of shyships, far less improved versions.
Air Angles: I'm pretty sure it's already clear. It's a part of the "Swivel Mount" summary section and should be pretty obvious throughout the design. But yeah, its angles are (like I said) one of its most important aspects.
Air coverage: The current idea is that the AS-HAC-1 has a drastically improved RoF, and that combined with the easy aiming makes it able to effectively snipe carpets out of the sky. Missed shots matter less when you're able to reload a
lot faster, after all. I do want to do flak shells and the like, but that's out of focus for this design.
Penetration: Well, this is why I mention the part about revising AP shells a lot when talking about the AS-HAC-1 and airships. But we know from experience that our HC1-E shots can pierce their armor at the right angles and whatnot, and the airship probably has less armor. That and smaller shot = higher speed + less penetration area. The super-improved rate of fire combined with this
should make it somewhat effective against airships, but I still think we should revise AP shells regardless.
I believe that it should be better than perfect insulation. Perfect insulation will tend to cook people as they produce heat. Given that it cannot change temperature, it stands to reason that it cannot allow temperature through it, there is no mechanisms for thermal energy to penetrate without radiating by heating the surface or using infrared radiation. Certainly, people need to breath, ia suit of armour would have some weaknesses, but they could run it through a filter system to remove most of that by having grids of cool metal that the air would have to pass through. It would also mean that if we developed a shatter-shield that rapidly alternated objects between extreme hot and cold using the tower of forever frost's effect that projectiles made from this stuff would be not merely resistant, but completely immune. The same applies to a heat0shield that would vaporise incoming projectiles. And they could have completely sealed A.P.C.s that would be immune to fireballs until they opened them. It is just extremely scary to see things like "their antimagic completely erases all of your starting spells and everything derived from them" and "Their new metal is completely immune to your starting wand, and everything derived from it.".
This seems to just be your dislike of their metal's properties, which is fine, but I
would like to point out that if their armor did indeed block all temperature changes through it that'd be one of the biggest nerfs ever to our stuff. It would make our towers of frost useless and our fireballs
much less effective when all they need is a new design/revision to fix that problem.
I've made a new APC design based on what we learned from our little "theoretical experiment" last design and experience from the STV-1 Restless.
I'm assuming that the Restless miniaturized the steam engine as that was explicitly stated to be a very high priority goal of the design.
I still prefer the AS-HAC-1, but this is something to consider. We need our own game changer.
(Future?) Design: AS-APC-1 "Guardian"The Guardian is a natural evolution of the AS-STV-1 Restless. We've realized that our troops could be carried to the front lines in a matter similar to the Restless, but without needing rails and protected.
So thanks to our experience in land vehicles, we can now invest into a solution to get our troops to the front lines.
The design is, in a way, a combination of the engine and personnel wagons for the Restless. The Guardian has a hull made out of Crystal thick enough to deflect ballistae shots, lightning, and fire bombs. 10 troops can """comfortably""" sit inside in full combat gear, on """comfortable""" seats lining the walls facing the Guardian's steam engine that goes along the center of the vehicle's inside. The steam engine is developed to be a
bit smaller than the Restless' steam engine, which is already our smallest yet. Extensive cooling circuits have been added to the steam engine, in addition to already-present cooling methods, to keep it and the cabin from overheating. Small ports are located on the front and are designed specifically to keep
any Moskurger projectile, no matter how lucky, from entering the cabin. A driver's seat is placed near the port along with basic controls.
The steam engine controls two "caterpillar tracks" that use wheels to move connected strings of smaller crystal plates which contact the ground. These tracks are capable of allowing the APC great movement over any terrain. Any wear and tear on the tracks is solved by our crystal's regenerative abilities. The driver has control over each side's set of wheels - back and forward for each side. Combined, these controls allow them to completely steer the Guardian.
The Guardian is powered by a battery of AA magegems. Thanks to the continuous nature of the steam engine meaning it can mostly rely on non-energy-intensive circuits and the like, the Guardian is fairly energy efficient. A full battery should be enough to last for three hours completely independent from a wizard. Generally, it's advised that an apprentice accompanies a Guardian, but they can operate fine without one.
The result is a formidable vehicle that allows our troops to safely cross no man's land and ballistae-defended areas without harm. It can move over just about any terrain, holds 10 troops and completely protects them from any possible threats. Lightning has no exposed weak spots and no metal to damage. The crystal is nonflammable and any kind of oil just sits on top of the crystal hull, harmless; in fact, a Guardian on fire tends to be rather intimidating. Moskurger spells are useless against it, and arrows bounce harmlessly off the hull without so much as a scratch!
The vehicle is based heavily off of our experience with the Restless, and thus shouldn't be too difficult to design.

I think an APC is necessary before we start developing things like steam rifles.
Sure, steam/magic rifles could be useful as snipers, but we should make sure they can be fully useful before spending a design on them. At the moment, our troops are barely, if at all, getting to the front lines. We need to fix that before we start developing things for close combat, I feel.
But this design should not be done this turn. For one, sea combat is important and this would be useless there. It'd be useful on land, but leaves their air advantage uncountered (and closer to
completely nullifying our artillery advantage).
Also, we should really
revise our steam engines to be more powerful at some point.
It'll increase the speed of our Crystalclad (outrunning airships?!?!?!?!?!?!?!?!?!), increase the speed
and capability (higher inclines) of the Restless, and make this APC faster.
