I kind of like the idea of the AS-SPA, so I wrote a more extensive fluff-heavy version. This good?
Design: AS-SPA-1Uses Research CreditToo long have we allowed Moskurg to control the sky.
Perhaps it's a good thing. They've grown complacent with their "airships" and carpets. They don't know how to truly utilize the nature of air warfare. But we do.
The AS-SPA-1 is what we call a
gyrocopter - it houses a single steam engine that powers two rotors, one for lift and a smaller one for control. The entire construction is made out of crystal, making it tough, light, and cheap.
The steam engine is also made of crystal, making it lighter and more durable, especially given the crystal self-regeneration. It also benefits from the miniaturization of the steam engine that occurred during the Restless project. If required, we're willing to increase the power of the steam engine as part of the project.
Nickel circuitry powers the vehicle. Using techniques learned from countless past designs and the timer incorporated into the newer Equalizer, we can successfully make circuitry "smart" enough to allow for easy control of the steam engine, cannon, and rotors.
This is a single-seat vehicle. The single seat is open-air, though it has a cage-like design giving decent protection against arrows and other projectiles while its closed top protects the occupant from lightning.
An AS-HAC-1 is integrated into the front of the cockpit, with its swivel controls accessible to the driver from inside. Ammunition is also stored in the aircraft - not enough for extended bombardment, but more than enough to easily defeat its foes in the air. The AS-SPA-1 can always simply quickly return to base for reloading, after all.
The AS-HAC-1 is useful against any target - ground or air. Carpets can be shot down, airships can be shot at where their armor is lacking, and the ground can be bombarded from above.
A basic integrated AA Magegem buffer is designed to allow for up to a minute of flight with a mundane user (but no use of the cannon). This allows mage pilots to be able to switch their complete focus onto other things without constantly paying some attention to the engine.
The gyrocopter is also light enough to be stored on a Crystalclad for quick deployment at sea. Given its armor and the lacking air-to-air weapons Moskurg has, just using one AS-SPA-1 per ship shouldn't be of issue. This pushes a Crystalclad's weight limit, but during combat the AS-SPA-1 should be deployed regardless, so it shouldn't affect a Crystalclad's combat performance. At land, the Gyrocopter can be transported via train, fly itself to the theatre, or by some regular method. Makeshift landing sites can very easily be prepared by our soldiers.
Disregarding ammunition for its cannon and the needs of its pilot, the AS-SPA-1 can stay in the air indefinitely. It can fly across the sea, land - anything. This combined with its tough crystal construction means that it can very effectively close the gap between it and an airship, continue operating at sea without a Crystalclad, and much more.
TL;DR: A 1-seat crystal gyrocopter armed with an AS-HAC-1. It may not have extreme firepower but it's very durable, can stay in the air indefinitely, be very effective against their airships + carpets + ground forces, and just secure the air in general. Can serve as a scout too. The crystal construction + crystal regen should make it resistant to pretty much anything they have. A closed top prevents lightning from hitting the pilot, it has a crystal engine eliminating that weak point. A cage-like design protecting the cockpit should give some protection against direct projectile attacks too.
