Specifications - USCGC Diligent


With human expansion now moving out of the Earth/Luna system, the United States Coast Guard saw a need for a new breed of ship to patrol the new high frontier. In 2078, the USCG selected Advanced Orbital Systems High Endurance Cutter design for implementation. Based on a mixture of proven technologies and cutting edge advances in material and physical sciences, HEC cutter design was the first true interplanetary ship purpose-built by mankind.

With its compact fusion plant, as well as its mylar power collection sails that would receive beam power from Shackleton Crater’s power transmission facility, the HEC design could theoretically make a trip to Mars and back to Earth without needing to refuel. This was demonstrated by USCGC Courageous on her maiden voyage to Mars in 2081, where she beat the Chinese People's Liberation Army Navy record by twelve days.

Renamed the Virtue class, 12 of the cutters were ordered with the second wave of three cutters laid down in orbit at the Freedom Space Tether Station Yards: Fortitude, Resolute and Valor. Each cutter of the Virtue class was allocated a pair of 4th Generation small boats, the Sojourner class. These small boats had transatmospheric flight capabilities within the thinner Martian atmosphere, allowing SAR and customs enforcement operations to stretch from high orbit to the Martian surface where sprawling mining operations are now underway.

Notable Examples
USCGC Courageous: Earth/Mars transit of 50 days. Currently Assigned to Ares Gateway Station.
USCGC Resolute: Lost with all hands during rescue operations in the Martian Trojan Point.
USCGC Fortitude: Pivotal in rescue operations at the Arabia Terra Mine Collapse.
USCGC Valor: Assigned to Mars Area, Ares Gateway Station.
USCGC Diligent: Assigned to Luna Area, Perry Crater.

Systems & Features

Power Plant General Electric RC70 Laser Ignition Fusion System, secondary stowed mylar solar sail rated for megawatt absorption, tertiary emergency solar cell array. (Fusion, beam power, solar)
Propulsion Three Boeing Space System VASIMR plasma drive’s, as well as numerous reaction control jets mounted on the hull.
Armament Keel mounted rail gun, 100mm depleted uranium slug. Dorsal and Ventral ball turrets autocannons. AI operated point defence laser grid (Photon CWIS). Small arms and minimal crew-served weapons aboard.
Artificial Gravity Thrust Gravity whilst underway. When at rest the ship is able to separate into two sections connected via a cable. Venere engines on either section then fire, spinning each section around the tether's centre point to generate gravity. A small tether inspection pod is able to traverse the tether at full extension for crew transfer between Habitation and Drive sections.
Small Boats Two Sojourner class small crafts rated for low-density atmospheric flight as well as near space flight. These are stored on either flank of the Virtue-class fore of the engineering hull, and are serviced via two mechanical arms.
