Tractor Beam and Gravity Well 3 with graviton generators in sci console slots. Tractor beam repulse also. Cloaked tractor beam mines in an aft weapon slot and mine powers for tact bofs Maybe chron torps.... And that pink circle pushy thing
The ones called from Fleet Escort leave after combat... at least in my experience. I'm not aware of pets for feds especially two interpred or even those as carrier pets.
