Duke Cornwall-Class
Category: Battlecruiser (Support)
Variant: Medium
Designer: Robert Archer
Mark I
Draft 1
Date: 06/19/2020

HISTORY AND MISSION OVERVIEW

In 2367 in the aftermath of the Battle of Wolf 359 many in Starfleet’s core building firms saw the need to up gun Starfleet’s rebuilding efforts with an assortment of ships to counter a future Borg or other threatening force’s incursion to the Federation. To this effort came classes like the Akira, Steamrunner, and Sabre classes, as well as numerous other refits and redesigns of aging and proven classes already in the Fleet inventory.

One such new design which came to fruition in limited numbers was the Duke Cornwall class medium battlecruiser. Meant as a fast, heavy armed interceptor like ship, as well as a command-and-control ship for fleet engagements, troop and high security transports, and combat profiles. As 2368 dawned, the Duke Cornwall class entered production from the shipyards around Andoria, soon gaining the class motto of ‘Put up your Dukes’ by the crews who served on them due to the robustness of its construction and firepower for the time.

Mission Profiles

The Duke Cornwall class is suited to the following mission profiles:

Troop and high security transport
Frontline and combat support roles
Fleet command and control support
Cargo and supply transport
System and border patrols

STRUCTURE AND CONSTRUCTION

The Duke Cornwall class is made up of a circular saucer connected to a filled in U shaped secondary hull. Projecting downward on short static pylons, to port and starboard, are the ship’s two conical shaped nacelles.

The ship’s superstructure is made of duranium metals with a triple hull layer measuring 3.0 centimeters thick. Layered between each layer are combat energized duranium paddings. Layered atop the final outer hull layer was 8.0 centimeters of Rodium armor plating. The entire height of the Duke Cornwall spans 12 decks, with decks 1-5 encompassing the saucer and 6-12 encompassing the engineering hull.

SCIENCE AND REMOTE SENSING SYSTEMS

Sensor Systems

The Duke Cornwall class makes use of the Type-VII sensor system. Made up of numerous grouped palettes about the edge lines of the saucer and secondary hull, the system has a low-resolution scan of 3.72 light years and a high-resolution scan of 11 light years.

Computer Core / OS / Network systems

The Duke Cornwall class makes use of a single isolinear data storage computer core and network. The core is positioned on the forward areas of decks 11 and 12 behind the ship’s main deflector dish. It runs on the LCARS 5.0 operating system with MAJEL interface.

WARP PROPULSION SYSTEMS

The Duke Cornwall due in part to its need for speed to intercept incoming enemy forces was equipped with the Class-8 warp core. The core has a Cochrane rating of 1,909+, a cruising speed of warp 6, a max sustainable speed of warp 9.2, a max velocity speed for 12 hours of warp 9.6 and an emergency speed of warp 9.8 for 3 hours.

IMPULSE PROPULSION SYSTEMS

The Duke Cornwall has a single impulse engine situated on the aft center areas of the saucer on decks 2 and 3. With this combat ready engine, the Duke Cornwall can reach a full impulse speed of .30c in 40 seconds and a full stop in that same time.

TACTICAL SYSTEMS

Defensive Shields

The Duke Cornwall makes use of the Type-10 Shield array system. The system has a maximum graviton load of 2,150 MW and a maximum dissipation rate of 5.84 x 10^5 KW. The system also has metaphasic programming for protection against solar radiation, solar body entry, or other similar anomalies.

Arranged in an oval shaped inset on decks 11 and 12 is the ship’s main deflector dish.

Phaser Systems

The Duke Cornwall carries ten Type-IX phaser arrays. They are positioned as follows:

One array dorsal and ventral on the saucer, shaped as a half circle with 100 emitters each.
One array to port and starboard, dorsal, and ventral, mounted on the nacelle pylons with 25 emitters each.
One array to port and starboard dorsal and ventral on the forward and aft edges of the saucer and engineering hull with 25 emitters each.

Each array is capable of a max energy output of 3.8 MW to a maximum effective range of 225,000 km.

Torpedo Systems

The Duke Cornwall class carries four Type-4 burst fire torpedo launchers. The burst fire launchers are mounted with 3 forward and 1 aft, within the engineering hull on decks 7 and 8. The burst fire system can fire 5 torpedoes/probes every 10 seconds, out to a range of 3,500,000 kilometers.

The Duke Cornwall carries 300 casings divided as follows:

270 standard photon torpedoes
30 assorted scientific probes
