So I'll start by saying I don't think his is "competitive at all but I am considering running this for giggles. Maybe paired with a couple of naked K's as back up.
Dengar — JumpMaster 5000 33
Deadeye 1
Advanced Proton Torpedoes 6
Extra Munitions 2
Recon Specialist 3
R4 Agromech 2
Punishing One 12
Ship Total: 59
Land in Range 1 in arc. Take focus action. Gain a second from recspec.
Deadeye an APT into target and gain a TL from the agromech. Gives a 5 die TL attack where you can natively modify 3 focus to hits.
Target returns fire (because it's stupid) and repeat the above with the second APT.
Single turn..2x 5die target locked attacks both with pseudo focus built in.
Now in reality this dream scenario would be unlikely to pan out. But.. I think it works in theory? Away from the dream scenario, landing in range 1 of anything in arc you perhaps more likely just saved yourself from being attacked at all as if they survive the first torp, they won't want to eat a second.
