This is a Battle Cruiser. For the moment, you can call the spinal mount a double Laser (2Rl+d8), and the antennas on the top can be Sensors (1Y). The spring launcher on the side can be a Frame Catapult.
This flotilla currently has the Battle Cruiser in the center flanked by two Death's Head Destroyers. The Strike Destroyers running intercept in front and back. With five ships and 20 attachments it will probably be the Primary Attacker.
