I asked ebbor, and the core and warhead are already the same thing. So ^that^ won't work. Instead, here are my two options:
More missiles:
AAA v2: The aim of this revision is simple: to increase the ammo capacity of our missile turrets, without significantly increasing bulk or cost. To achieve this, we have made the missiles more compact, by combining or downsizing elements where possible. Most notably, we replaced the Elerium in the core with 'pre-destabilized' Elerium, which generates less power but generates a larger explosion- we then downsized the core so that the explosive power remains roughly the same (the loss in power generation should not be an issue, as the core is still more than large enough to power the missile's gravity drive). The full AI core has been pared down, removing unnecessary capabilities, and miniaturising the rest. The gravity drive (in a manner that was totally not inspired by observation of XCOM's new fighter) is no longer capable of completely arbitrary movement- should it for some reason need to make a 180° turn, it will need to actually turn, rather than simply accelerate in the opposite direction- which cuts down on the required size considerably.
Ideally, we exchange a minor drop in performance for an increased ammo capacity, without increasing cost or space usage.
Or better missiles:
AAA v3: We ordinarily go to extreme lengths to keep Elerium cores stable. Experience from developing Elder's Scorn shows that it is remarkably hard to destabilize them, in fact. However, this need not be the case. In fact, we can make Elerium
less stable, simply by bombarding it with the right sort of particles until it is loaded with energy just waiting to be released. This makes it so that one must be very careful when drawing power from the Elerium, as drawing too much could cause it to explode prematurely.
So we replaced the AAA's core with this pre-destabilized Elerium. It should generate less power but a bigger boom. The size of the core relative to the missile means it still generates more than enough power to keep the thing airborne and agile.
End result: a more powerful missile.
I vote for more, since we don't want to be using missiles more powerful than necessary against Skyrangers and Ravens. Though purely versus Talons, I think more power would be more effective.
