There was a TIE with a turret. Probably the only chance for the Empire to get a turreted ship.
There are many Rebels out there, demanding a bomb slot for their Y-Wings. So you want our Proton Bombs, Seismics and Mines?
And this is the imperial answer:
The TIE Aggressor: "Eat your own ion and blaster medicine, rebel scum".
