Military Laserstar, i.e. a large warship carrying a single laser weapon as its primary armament. You're looking at a high-energy laser generator firing through a 34 metre multisegment primary mirror. Some liberties taken for a dramatic action shot in the second image, of course in reality no beam would be visible in the vacuum of space. Propulsion is a inertial-confinement fusion engine that also generates power for the laser by magnetohydrodynamics. The large mirror, 500 MW laser generator and UV-band laser make it good for a million kilometres or so max range. Large radiators help dissipate the vast amounts of waste heat generated, in conjunction with an internal heatsink. Paintjob is somewhat whimsical and based on the works of Chris Foss.
