Autocannons - Would be buffed to do IFV type damage from the sky and explosive damage to movecraft, so useful for carrier air support but less useful against other planes.
Fighter Guns - No damage against anything but planes
Bomb boys - same
Torpedos -same
Missiles - same

Classes of plane

1) Air Support: 200-500 blocks
- Able to have 1 Autocannon and 2 fighter guns
or
- 2 autocannons and 1 fighter gun
at 400 size and above it can have an extra autocannon
Speed: 0.75* speed of a fighter
Turning: twice as fast as a fighter

2) Interceptor: 200-400 blocks
- Able to have 4 Fighter guns which scale up with size (minimum 2)
- 0.75% the speed of a fighter
- Turning 25% faster than a fighter
- Fuel burn 25% more fuel burn

3) Fighter: 100-300 blocks
- Able to have a maximum of 2 fighter guns or 1 fighter gun and one torpedo launcher/missile.

4) Bomber: 200-500 blocks
- Able to have 3 bomb bays that scale up with size
- Able to have 6 torpedo launchers, which scale up with size
- 0.75% the speed of a fighter
- Drift reduced
- Can swap out 25% of its firepower for 1 Fighter gun.

Carriers:
- All planes piloted from carriers DECKS would be 25% stronger in hull.
- Carrier should be able to repair itself and its flight deck, or spawn planes on it.

AA:
- AA damage would be reduced by half, rn it makes planes unusable.

If you are against these, i have the following question.

Why use a Carrier over Submarine?
They have similar damage outputs and both retain an element of evasion yet the Carrier is a lot easier to target and intercept. Moreover, a single few shells to the carrier flight deck render it useless. In addition the carrier is maybe 4x as expensive.
Planes give points when sunk too.

Therefore the only reason one might use a carrier is if the damage output was enough to justify the complexity and fragility of the craft.
