Federation U.S.S. Dupleix class Perimeter Action Ship (Star Trek):

From: Starfleet Prototype

This design is meant for the times between the movies Star Trek Two: Wrath of Khan and Star Trek Six: The Undiscovered Country. This could easily also be used in Next generation times as ships pulled from Mothball / Reserve fleets to cover the huge losses incurred while fighting against the Borg and Dominion.

Escort class vessels are less expensive to manufacture than the Heavy Cruisers and other multi-purpose vessels. In many cases, two escorts can be built for the cost of one Enterprise class cruiser or about two thirds of the cost of an Avenger class frigate. Of course, combat performance is reduced but the essence is still kept in these vessels and these ships are still quite dangerous when in the hands of a capable captain. Many escort class vessels spent most of their time in combat border patrols and so long endurance and repair capacity can be reduced when compared to cruiser designs.

Most previous designed Escorts only had a single warp nacelle which limited their performance. The Dupleix was designed to use two nacelles to allow for higher speeds but their are in an unusual configuration with one warp drive on top of the other. This slighty reduces the maneuverability of the vessel at warp speeds but these was understood when the design was developed. The ship carries seven phaser banks but does not carry any torpedo launchers. Instead it carries a mega-phaser on each side of the warp nacelle structure. This gives the ship incredible firepower but the ship is limited with respect of range when compared to the Photon Torpedo launchers.

These ships do not have a hanger bay and cannot carry any fighters. The ships also do not have any space for flag facilities and it is planned for theses ships to act as escorts for Dreadnought Flagships during hostilities. The ship only carries a small detachment of marines assigned to shipboard defense. In order to reduce the size and cost of the ship, both shuttles and fighters were removed from the ships design. This has left the tranporters and other shuttles to transport all crew and cargo transfers.

This design is written to be able to interact with modified phase world rules. See Revised Starship Rules for Phase World / Three Galaxies for more details. There is a lack of hard detail on this ship. Some materials have suggested accelerations that are simply beyond scope. I have taken a moderate level in writing up this starship for Phase World because otherwise the ship would either be far too powerful or far too weak for Phase World. Warp speeds are far slower than the FTL speeds for Phase World but they are very close to those from the original series and Star Trek: The Next Generation Technical Manual. Also, a note on the mass of starships. The original sources indicated much smaller masses for starships than Star Trek: Deep Space Nine Technical Manual does and where possible, both masses are listed for the gamers to choose which one seems most appropriate.

Model Type: NCC-2346
Vehicle Type: Perimeter Action Ship
Crew: 311 (38 Officers and 273 Enlisted)
Troops: 50 Marines

Vehicles: None

M.D.C. by Location:

Mega-Phaser Cannons (2, between warp nacelles):1,200 each
Siege Phaser Cannons (7 banks of 2 each):800 each bank
Sensor Suite:1,500
Warp Nacelles (2):15,000
Impulse Engine:6,000
[1] Primary Bridge:12,000
[2] Primary Hull (Main Body):30,000
[3] Variable Deflector Shields:4,000 per side (24,000 total)

[1] In reality this is how much damage needs to be done for a weapon to hit the bridge through the ship’s armor. This ship does not have an auxiliary bridge. Even if the bridge is destroyed, the ship can still be piloted from engineering but ship is -3 to dodge and all weapon systems will be at local control. Weapon hits near the bridge that do not penetrate the ships integrity can injure crew members on or near the bridge.
[2] Depleting the M.D.C. of the primary hull will put the Cruiser out of commission. If the secondary hull is destroyed, the primary hull will remain capable of sublight travel and weapons may still be fired. If the primary hull is destroyed, all internal systems will shut down, including life support and internal gravity. The ship itself will be an unsalvageable floating wreck.
[3] Shields positions can be varied and all could be combined in one shield. Shields regenerate at the rate of 5% (1,200 M.D.C.) per melee round.

Driving on the Ground: Not Possible.
Sublight: Has a special sublight engine that allows the ship to travel up to 60 percent of the speed of light. Star Ship can accelerate/decelerate at the rate of 0.7 percent of light per melee. As an alternative, the starship can reach .99 of the speed of light but is normally restricted to slower speeds so that starship is not effected severely by time attenuation that occurs at the higher sublight speeds.
Atmospheric Propulsion: Cannot travel within an atmosphere efficiently.
Stardrive: Uses a warp engine that allow ship to travel at Warp Factor 8.5 on cruise (0.07 light years per hour), Warp Factor 10.8 Flank (0.144 Light Years per hour), and Warp Factor 14.0 Emergency (0.313 Light Years per Hour). Warp speed is raised to the third power to figure out how many times the speed of light the ship travels. These speeds are very slow when compared to Phase World ship, so if used in that universe, they could be increased enough to operate within Three Galaxy speeds but should not exceed them.
Maximum Range: Effectively Unlimited by either drive system. The ship carries about three years worth of supplies on board and a small hydroponic section.

Statistical Data:
Length: 880.9 feet (268.5 m)
Height: 242.45 feet (73.9 m)
Width: 464.89 feet (141.7 m)
Mass: 123,000 Metric Tons (Starfleet Prototype)
Power System: Primary power system is Anti-Matter with a 20 year life span. Ship normally only goes 5 year between refueling.
Cargo: Cargo holds are scattered about the ship that allows for carrying up to 27,500 tons (25,000 metric tons) of cargo in addition to standard compliment of supplies and ammunition.
Market Cost: 4 billion to construct. As far as it is known, the Federation does not sell their starship designs to other interested parties.

Weapon Systems:

  1. Two (2) Mega-Phaser Cannons: Located between the warp nacelles, and used as anti-capital ship weapons and can take out frigates in one shot or do large amounts of damage to bases or larger ships. The Phaser cannons can be combined or used separately. They cannot be used faster than the speed of light. Weapon has standard penalties to hit fighters and small targets. The barrels can be fired either forward or behind and can be rotated 30 degrees horizontally or vertically.
    Maximum Effective Range: 93,300 miles (150,000 km) in space and 93.3 miles (150 km) in an atmosphere.
    Mega Damage: 1D4x1000 M.D.C. each and can be combined for a damage equal to 2D4x1000.
    Rate of Fire: Maximum of Two (2) times per melee per cannon.
    Payload: Effectively Unlimited.
  2. Seven (7) banks of 2 Siege Phaser Cannons: Secondary energy weapon system with four banks on the top and three banks on the bottom of the primary hull. The weapons damage is about equal to laser cannons used by the CAF but the Phasers have a greater rate of fire. The phasers are also slightly shorter ranged but only slightly. Both Phaser Cannons in each bank can be linked or can be fired separately. They cannot be used faster than the speed of light. Weapons system has half the normal penalties to hit fighters and small targets.
    Maximum Effective Range: 12,437 miles (20,000 km) in space and 12.4 miles (200 km) in an atmosphere.
    Mega Damage: 2D4x100 M.D.C. each or 4D4x100 for both in a bank.
    Rate of Fire: Maximum of Three (3) times per melee each cannon.
    Payload: Effectively Unlimited.
