Would an option be homing missiles?
Assuming: ASF is standardized on gun type weapons.
Anti missile flares.
A Secondary of AOE homing missiles in a limited supply, like TML. Restockable at air staging. Toggleable fire at will feature like overcharge.
The flares can make a missile not hit your plane, but a missed missile still explodes, making it more effective against blobs than small squads.
Fire control tower you can build and 'assist' defensive buildings to, tower controls target acquisition and can toggle from focus fire to spread fire, allocating targets to lessen overkill and lost missiles. Gives a good boost, make it like a radar tower, juicy tactical target. EMP volatile when it's killed, power drain. Spitballing here.
