Really, though, we're better off in many ways compared to Moskurg. Namely, the relative durability vs damage of both sides.
A single Lightning can take many hits from both ballistae and lightning bolts. Yet it can destroy a Moskurg airship in merely two shots (and this is still very quick when factoring in breech-loading) and a fighter in one shot. Yes, it may not be as effectiveness due to its slower rate of fire making it harder to dogfight (IF ONLY WE HAD THE CAF), but it should be much better than the Moskurger equivalent.
Unfortunately, the turret is practically useless against fighters. Not because of its rate of fire, but because of tracking. The turret rotates/aims slower than a Moskurger fighter flies. We can't actually aim our guns at their fighters, which means that we will lose engagements. Powered turrets will mean we won't auto-lose to Moskurger fighters. We may not have 100% effectiveness due to rate of fire (we should still get the CAF soon!), but any effectiveness is better than 0%.
And powered turrets will be necessary for any weapon that needs to be pointed at the enemy. Which is every relatively effective weapon we have right now.
Also power armor.
The MKPD can totally be used for power armor. And tons of other cool things. But let's not get too ahead of ourselves.
And in other news, RAM mentioning webs gave me an idea.
Future Design: Silkcrystal
Here we are, looking back at decades of complaining about the relative brittleness of crystal, when we had the answer standing in front of us the whole time.
Some apprentices playing experimenting with the mistake spell Webs yielded extremely interesting results. The spider silk material comprising the webbing is extremely tough. Of course, it comes in such tiny quantities in thread form making it normally impractical for us. But we're Arstotzkan!
Webs is a conjuration spell. One of the original three from the spell book, in fact. Since we acquired that spell book, we've made factories dedicated solely to conjuring crystal, a material that didn't even exist in the book. It may have been impossible then to make this spider silk on an industrial scale in the right form, but with our society and industry based on conjuration, it should almost be a trivial task.
But instead of creating entirely new production lines for this, we can simply use it to upgrade our crystal. Use our experience with integrating and revising different types of crystals along with the conjuration knowledge garnered thus far to do so. Merge the best properties of this spider silk and crystal and apply the new crystal to every fabricator in the kingdom.
Silkcrystal should, obviously, no longer be brittle. In fact, it should be magnitudes better than Crystal if we succeed. Imagine crystal no longer shattering to lightning bolts. Imagine being able to endure infinite ballistae bolts. Imagine being able to treat their new railgun as if it were nothing but a fancy ballista. That is what Silkcrystal may be able to do.
Furthermore, Silkcrystal should also allow us to exert much more control over the flexibility of the crystal. Though while it should be very easy if Silkcrystal succeeds, we'll leave that to its own revision or part of a design.
TL;DR: Merge spider silk (From our Webs spell) with Crystal, make SUPERCRYSTAL.
