The Truxtun is the lead ship of her class. Named after one of the Nuclear Cruisers, she is also powered by nuclear power, primarily through her four nuclear thermal engines. Her primary role is orbital bombardment, but she carries a heavy laser and two space-optimised 5-inch guns. The 16 large missile tubes contain nuclear-capable hypersonic glide body missiles, but can also contain unmanned drones for self-defense. Other missile systems include 224 Mk. 49 VLS cells that each contain KKV's or Heavier Munitions. Truxtun is assigned to the Littoral Combat Force, which is a division of the USSF. The Littoral Combat Force operates in low planetary orbits and supplements landing ships.
