Adding more to this, with some aircraft variant ideas. Variants should be selectable as a module, the same way that changing certain modules on the Tarantula and Medusa will unlock or lock other options. I feel like variants would be a great way to add a lot of variety to the game without requiring a lot of work. We are lots of different configurations for aircraft in the real world all operating together. So here's a few ideas.
Cricket variants
Cricket-J is a jet powered bomber Cricket. It's top speed is only moderately increased, but the jet gives it much more power for acceleration and climbing, allowing this variant to carry more/heavier bomb loads.
The jet engine runs hotter, and makes the Cricket-J more vulnerable to IR missiles, and carries only enough fuel to loiter in the air for short sorties.
This would give people their bootleg A-10 platform in a format that I think fits the world with enough benefits and downsides to be balanced and fun. I envision the Cricket-J as something kept with reserve forces designed to respond to ground breakthroughs.
Cricket-X1 is an experimental weapons platform based on the Cricket that was used in development of the Chicane's weapon systems. It would be essentially an upgraded, more expensive Cricket with some extra toys to keep it useful late game.
Primarily an upgraded engine delivering moderately more power. This lets it forgo it's nose mounted sensor package for the chicane's rotary cannon gimbal. The cannon has a noticable effect on the stability of the plane when firing, and the whole platform is significantly heavier and more sluggish
It also has access to the Chicane's big Lynchpin pods and 4x AGMs. It has no air to air capability. This makes it a fun alternate A-10 inspired option that's purely for fighting ground forces while others go after air targets, although you could probably ruin a few people's day with the gimballed cannon if you were brave enough to try it
