The Phoenix-class Battleship is a specialty vessel designed for planetary and system bombardments from interstellar speeds. It is designed to quickly accelerate to interstellar speeds, deploy its interstellar ramjet, and siphon off a portion of the collected interstellar medium to store in massive graphene balloons, each capable of storing almost fourteen times its own weight in hydrogen and helium gas form the interstellar medium. These can then be deployed prior to entry to a system to destroy incoming fleets or (especially) planets and habitats. As each of the spheres contains nearly a yottajoule of energy, a single one can vaporize a continent-sized McKendree cylinder, and a thousand can de-terraform even the largest of planets from T3 back to T0. The ship, still traveling at over 0.10c, then just flies out of the system unharmed.
While a Phoenix-class ship is no match for a Griffon-class ship in close combat, Phoenix-class ships can outmatch even a Dragon-class Titan when it comes to quick-and-fast orbital bombardment. Thus, Phoenix-class ships are considered a specialty weapon, and the ships themselves are not designed to be front-line fighters. Nevertheless, Phoenix-class ships still have four hundred thousand thermonuclear missiles at their disposal, and so are not unarmed in case of an emergency.
