If the ship in question already has the WINGCOM hullmod installed, just assign an officer to command the ship or pilot it yourself. The ship's WINGCOM squadron will automatically appear once you mouse over the hullmod in the Refit screen, or in your Intel menu under "WINGCOM Management" (should be automatically tagged as important intel at the start of the game).
If you want to install WINGCOM on ships that don't have it by default like carriers, head over to New Meshan in Gamlin to pick up a copy of the hullmod from the Arma Armatura market.
