Federation U.S.S. Excelsior class Battleship (Star Trek):

This design is meant for the times between the movie Star Trek Two: Wrath of Khan through Star Trek: The Next Generation Episodes, Star Trek: Deep Space Nine, and Star Trek: Voyager Episodes. It seems like they are a strong and very common ship class.

These ships served as the backbone of the Federation for many years. They took the place of the Constitution class starship for space exploration in the time between the retirement of Captain James T Kirk and the construction of the new Galaxy class starship which took their place to some extent in that role. At this time, the ships were re-designated as cruisers as well.

These ships still serve the Federation in many areas and there are no plans in the federation to decommission the class any time soon especially with the needs the Federation has for all the hull that they can get. Some ships of this class have received upgrades. Upgrades have includes the increasing of the deflector shields and the increasing of the firepower of the ships phasers. All ships of the class have had their photon torpedoes replaced by quantum torpedoes.

While the design of this ship was not originally designed to carries families, many of the ships stripped out the marine compartments and replaced them with living quarters for families. Since the Federation had their incidents with the Borg and the Dominion, the quarters have been removed and converted back to marine berthing compartments.

While the ship class is equipped with none of the Mega-Phaser cannons that other classes, such as the Avenger class frigate, were equipped with, this ship is very well armed and is capable of fighting powerful enemies. The energy weaponry of this ship are twelve banks of siege phasers. Because of the problem with opponents attacking the Constitution class starship from the rear, it was decided that two torpedo launchers would be mounted to fire to the rear of the starship.

Flight two of the Excelsior class battleship included several key improvements. The main improvement was the addition of another impulse engine to improve the ships maneuverability when the ship is operating at sublight speeds. The armor of the ship was increased as well but the additional armor was added to other ships of the Excelsior when they went to the yards for refitting.

The class is listed with the starfighters the class carried when first constructed. If the ships is carrying shuttles in place of fighters, the ship carries 10 additional shuttles but since the incidents with the Borg and the Dominion, many of the ships are carrying fighters once again.

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-2000
Vehicle Type: Battleship (Heavy Cruiser/ Battle Cruiser by Phase World terms)
Crew: 510 (60 Officers and 450 Enlisted)
Families: 120 Families (Most have been replaced by marines)
Troops: 250 Marines, 200 fighter and Shuttle pilots, and can carry up to 50 passengers in addition.

Fighter Compliment:

24Tycho class light interceptors.
24Arco class attack sleds
18Argus Class warp fighters
10Standard Shuttles

M.D.C. By Location:

Siege Phaser Cannons (12 banks of 2 each):800 each bank
Torpedo Tubes (4):800 each
Warp Nacelles (2, secondary hull):15,000 each
Secondary Hull Hanger Door:4,000
Impulse Engine (2 on later ships of the class):10,000 each
Main Deflector Array:8,000
[1] Primary Bridge:15,000
[1] Auxiliary Bridge (Also used as Flag Bridge):15,000
[2] Primary Hull (Main Body):50,000
[2] Secondary Hull (Main Body):50,000
Connection between Hulls:15,000
[3] Variable Force Field:8,000 per side (48,000 total)
([3] Rebuilt Variable Force Fields:10,000 a side (60,000 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 have an auxiliary bridge. Even if both of the bridges are 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 bridges 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 or secondary hull will put the Battleship 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% (2,400 M.D.C. [3,000 for rebuilt shields]) 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. Original Excelsior class can accelerate/decelerate at the rate of 0.6 percent of light per melee round. Later Ship have 2 impulse engines which allows which allows ship to accelerate/decelerate at the rate of 0.8 percent of light per melee round.
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 9.4 on cruise (0.09 light years per hour), Warp Factor 11.2 Flank (0.16 Light Years per hour), and Warp Factor 12.6 Emergency (0.23 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: 1677.3 feet (511.25 m)
Height: 284.6 feet (86.76 m)
Width: 638.58 feet (194.64 m)
Mass: 2,350,000 tons (Deep Space Nine: Technical Manual)
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 60,000 tons of cargo in addition to standard compliment of supplies and ammunition.
Market Cost: 7.4 billion to construct. As far as it is known, the Federation does not sell their starship designs to other interested parties.


  1. Twelve (12) banks of 2 Siege Phaser Cannons: Primary energy weapon system with five banks on the top and five banks on the bottom of the primary hull The ship also has two banks on the top of the secondary hull. While this ship does not have mega-phasers, the large number of siege phasers is still very effective. 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. Several ships of the Excelsior class have had their phasers rebuilt to increase their firepower and range.
    Maximum Effective Range: 12,437 miles (20,000 km) in space and 12.4 miles (20 km) in an atmosphere. Rebuilt phasers have a range of 15,550 miles (25,000 km) in space and 15.6 miles (25 km) in an atmosphere
    Mega Damage: 2D4x100 each or 4D4x100 for both cannons in a bank. Rebuilt phasers do 2D6x100 each or 4D6x100 for both cannons in a bank.
    Rate of Fire: Maximum of Three (3) times per melee each cannon.
    Payload: Effectively Unlimited.
  2. Four (4) Photon Torpedo Launching Systems: All launchers are mounted in the secondary hull. Two launchers fire forward and are mounted above the main deflector array. Two launchers fire aft and are on the rear of the secondary hull. While the launchers are older than those used on the U.S.S. Defiant and other next generation ships, they can use new torpedoes and quantum torpedoes if used in later Next Generation times. Newer photon torpedo warheads carry more anti-matter.
    Effectively very similar to Phase World cruise missile launchers but instead of having groups of multiple launchers, Starfleet has concentrated on launchers that can launch more than one torpedo at the same time. There are two launchers that fire forward and two launchers that fire aft. Once spread of torpedoes has been launched, the launchers must reload and rearm before launching another spread of torpedoes. In the early service of this ship, it carried photon torpedoes which are anti-matter/matter warheads but they can carry quantum torpedoes when they are available.
    Torpedoes has a top speed of Mach 25 in an atmosphere and in space has an acceleration of 10% of light per turn (far faster than any starship). When drive goes dead, the torpedo will continue to travel in a straight line unless preset to self destruct or receives a destruct code but has very low odds of hitting star ships (Great for hitting bases and planets because target does not move and torpedoes when dead is at -25% to be detected.) See modified starship rules for more details - Sublight torpedoes have penalties to hit small targets but are all considered smart missiles. Launchers can launch on multiple targets each.
    Maximum Effective Range: Powered torpedo range is 8000 miles (12,875 km) in an atmosphere and 4,000,000 miles (6,437,376 km/ 21.5 light seconds) in space.
    Mega-Damage & Properties: Photon Torpedoes (Matter/Anti-Matter Warheads): Old Series inflict 2D6x100 each, Star Trek Movies One through Six inflict 3D6x100, and Next Generation inflicts 4D6x100 each. Quantum Torpedoes: 8D6x100 each.
    Rate of Fire: One at a time or in volleys of 2 per launcher, per melee round, for a maximum of 8 torpedoes per melee. Launchers are reloaded on the same melee and can be fired again on the next.
    Payload: 200 torpedoes (50 per launcher, launchers are mounted in pairs and can use the other launchers magazine if launcher is damaged).
