Looks like a frigate that is protected by some fighters with limited weapons? The fighters stay close to the frigate and are disabled if the frigates comm disabled?
Basically yeah. To elaborate a little more. The model of the frigate would have to have a docking bay added(for in mission launch/recovery) and the fighter model should be something smaller(by about half) than a standard fighter.
The only thing I worry about with SEXP's if that if you wanted to make multiple missions with a similar ship it would take a lot of copy/pasting to make a ship like that work.
Homeworld and Cataclysm both had drone frigates. Cataclysm's "Hive" frigate only had 6 drones but for Freespace I'm guessing 16 would be a good number as you can model a nice sphere with two 8-point cubes.
The drones also exploded(to keep the battlefield clean) when the frigate was destroyed but in a Freespace version they should just slow to zero and be inactive.
If anyone is interested in setting up a mission/make the models I'd be happy to write detailed specs for a drone frigate system.
