Nope.
It's got it's main beam (the BGreen IIRC) on it's chin multipart turret, and all the others are on those little side turrets that look like smaller versions of the big turrets. They're only single-part ones, though.
Thinking about it, the Orion's beam placement is decidedly odd. Pre-beams, it's main guns were the large turrets on the top and underneath, with the side turrets being smaller secondary guns. With the beams added, the small turrets become the main battery, and the multi-parts stay with the blob lasers. That would require massive internal modifications, as the power requirements for the beams would be much greater than that of the lasers. So there would have to be a major refit of the power grid inside the ship...
Nice turret, Singh, and great sketches Turnsky.
