I quote from the WC3 official guide book (the one with the "Making of WC3 CD").
"Call it iron butt. The super-heavy Sorthak occupies a dangerous middle-ground between a bomber and a corvette. It's just barely too small to lock a torpedo on, but definately big enough to be a major threat. It's remarkably fast and maneuverable for a ship it's size, and of course it's armored to the teeth, but what really makes the Sorthak a menace are its twin, independently turreted meson guns. It can effectively engage several Confederation targets simultaneously, from virtually any angle, and its extra-powerful shields make it hard to destroy, even against multiple opponents. This is the only fighter in the game whose rear is as every bit and dangerous and well-defended as its front. Fortunately, it has a fairly bulky silhouette, which helps during flanking approaches, but taking out a Sorthak is still a tough job from any angle."
I will also quote the weapons stats from the given statistical data
"Weapons
Meson gun (turreted) (4)
Meson gun (rear turreted) (2)
Missiles
Missile Hardpoints (2x4)
4 HS / 4 IR
Missile Decoys (10)"
The rendering of the fighter in the guide even shows the front dual meson turrets.
So all in all, take that info as you will. You guys "hired" me to give you technical advice and I am doing it. But because it is your mod, you are more then free to get Concordia back as your technical advisor again and do a complete change of the weaponry if the given data does not match your interpretation of what WC should have been.
