Sonic Rainboom Class Flagship

Named for the UGRNFSV Sonic Rainboom, these vessels are 3 kilometers long and are armed with 4 massive coaxial railcannons, 50 heavy turrets, and countless PD guns. Their armor is made of a neutronium alloy, making them virtually indestructible, and their shields have been known to (with help) survive the shockwave caused by a supernova.
