Because light fighters cannot use torpedoes - apart from tractoring them in and selling them for cash, I mean - and because the powerplant of the Patriot is so weak I just used up a full supply of the expensive Driller mines (more than $35000 credits) during mission 12, and even so I ran out of mines shortly before the 3rd generator was destroyed. Starkiller torpedoes have slightly more bang, the same refire rate, and are much less expensive (not to mention that you can launch them much further away than mines). I got the 2-minute warning about 5 km away from the jumphole and so I don't think I would have made it through this mission without the mines.
I did not want to swap any of the guns for a missile launchers because I wanted to have all four guns for fighting the reception committee at the other end of the jumphole.
P.S.: yes, I beat the game in a Patriot. I mounted the finest equipment I could get (class 3 graviton shield, Adv. Thruster, 4 x Adv. Scorpion) and in the later missions I also used about $100000 credits' worth of Driller mines and a few sips of Loch Lomond single malt. It was actually easier than with the Dagger.
