Columbia-class Heavy Battleship/Mobile Base

Overview

The Columbia-class heavy battleship is intended to function not only as a capital ship in the battle line, but as a mobile base, and even alone as a means of "showing the flag," a mission that they serve far more often than major combat.

As a capital ship, the Columbia class can simultaneously fulfill six war-fighting requirements: flagship for embarked planetary assault squadron, flag or general officer staff; fighter carrier, with a 150+ craft complement including fighter/attack craft, reconnaisance fighters, heavy lift shuttles, and other support craft; planetary assault launching platform, employing a variety of surface assault craft including the Navy's newest Landing Craft Utility (LCU), and other planetary assault vehicles; hospital ship, equivalent to the nation's finest local hospitals with 17 ICU beds, 4 operating rooms, 300 beds, a blood bank, full dental facilities, and orthopedics, trauma, general surgery, and x- ray capabilities; command and control (C4I) ship, with the Navy's most sophisticated communications capability; and assault provisions carrier able to sustain embarked forces with fuel, ammunition and other supplies.

The ship carries a complete expeditionary unit of Imperial Marines and their vehicles, as well as six fighter squadrons of 25 fighters each. A small complement of support vessels is also aboard.

The ship has additional cargo space of 5985 tons, with three 100 ton bays serving as access ports to the main cargo bay.

The ship has six launch tubes for craft 30 tons and smaller, and has two launch tubes for 100 ton craft.
