I encountered spike cruiser couple of days ago in Kerrat. I was in my sci destoyer, and was like... look an unsuspecting tac fed care bear in excelsior! That was my last thought. In 3-5 sec (i didnt expect that kind of dmg) I was burning on plasma fire while dem was eating my hull. While i was thinking what to do, and started moving my mouse to VM button, at 6th sec I exploded. I guess, its possible, but it has to be tac. Tho, easily countered with 2 hazard emitters, and sci trickery. Cheers.
That might have been me, ive been farming EC's in kerrat for the past week in my Fleet Excelsior

I built a fleet galaxy just for laughs. Got a few spike kills with it. Using romulan experimental beam and 7 turrets. Take the saucer off and preload beam overload 2 as it comes up also load beam overload 1. The trick is to not fire until both are loaded. Add to this the romulan weapon set 3 peice overload attack. You will need dem 3 as well. So basically stack all the consoles possible to load up on plasma damage.
Anyhow... dual beam overloads and 6 turrets with dem makes for a good spike. Is it ideal? Hell no. Is it funny as hell watching a galaxy kill someone in 2 seconds... sure is
