Dominion Jem'Hadar Battlecruiser (Star Trek):
The writeup of the Jem'Hadar Battlecruiser is designed to be used during the later Star Trek: Deep Space Nine and Star Trek: Voyager episodes.
It was first though that all of the ships that the Dominion used were small and light attack ships. This changed when the Dominion and the Cardassians became allies. At this point, Jem'Hadar Battlecruisers started coming through the Wormhole in the Bajoran star system. Since then, thses ships have become a major problem for the Federation and the Klingons. Although many were destroyed during the Federation / Dominion War, there are still large numbers of these vessels remaining in service. These ships normally operate in groups of one to three and are escorted by a large number of the smaller Attack Ships. Unlike the Attack Ships, these ships are not considered for suicide ramming missions. Along with being used as heavy combatants, the shiops are often used to carry large numbers of Jem'Hadar troops and as flagships.
On an individual basis, these ships are more powerful than the Federation Galaxy class starships and is considered to be about the equal of the Federation Sovereign class. The ships is armed with two heavy poloron beam mounts that are capable of inflicting massive damage but have a limited rate of fire. The main weapons fire forward and have only a limited arc of fire. To back these up, the vessel has sixteen Phased Poloron Beam mounts that are similar to those carried on the Attack ship but are mounted individually in turrets. When Jem'Hadar ships were first met, the Poloron Weapons were incredibly effective against shields but since then, they have been compensated for by virtually all Federation, Klingon, and Romulan vessels. The one weakness this vessel has compared to the Federation Sovereign class in torpedo launchers. The Dominion Battlecruiser carries only four launchers compared to the Sovereign carrying six launchers. Like the smaller Jem'Hadar vessels, the Battlecruiser has a cloaking device penetrator. The ship has lighter shields then might be expected and are equal to those carried on the Galaxy class but the ship has heavier armor than the Galaxy class. The ships are fast at warp speeds and equal some of the newest Federation designs.
The ships carry a huge crew but the crew also acts as marines for boarding and ground assault. It is figured than only about one fifth of the crew is required for normal operations. Most of the crew is in close packed spaces but the ships have more comfortable quarters for any founder or other non Jem'Hadar races that are on board.. Thses ships have full command facilities. To support assaults, these ships have a relatively large amount of cargo space.
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: Dominion Jem'Hadar Battlecruiser
Class: Battlecruiser and Heavy Troop Transport (would be classified as a Battlecruiser as well in Phase World)
Crew: 2500 (Act as both Crew and marines, the ship can be run by 500 crew members at full efficiency)
Passengers: 200 (More comfortable quarters than the crew)
M.D.C. By Location:
|Heavy Polaron Beam Emitters (2, Forward):||1000 each|
|Polaron Beam Emitter Turrets (16):||200 each|
|Photon Torpedo Launcher (4, 2 forward and 2 aft)||800 each|
|Warp Nacelles (2):||40,000 each|
|Impulse Engines (2):||15,000 each|
| Primary Bridge:||25,000|
| Auxiliary Bridge (Also used as Flag Bridge):||25,000|
| Main Body:||135,000|
| Variable Force Field:||12,000 per side (72,000 total)|
 In reality this is how much damage needs to be done for a weapon to hit the bridge through the ships armor. This ship does have an auxiliary bridge. Even if both of the bridges 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 bridges that do not penetrate the ships integrity can injure crew members on or near the bridge.
 Depleting the M.D.C. of the main body will put the battlecruiser out of commission. All internal systems will shut down, including life support and internal gravity. The ship itself will be an unsalvageable floating wreck.
 Shields positions can be varied and all can be combined in one shield. Shields regenerate at the rate of 5% (3,600 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 0.8 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 8.0 on cruise (0.117 light years per hour), Warp Factor 9.4 Flank (0.201 Light Years per hour), and Warp Factor 9.92 Emergency (0.380 Light Years per Hour). Speed is calculate using a formula designed to emulate Star Trek: Next Generation speeds. These speed 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. Ship carries about three years worth of supplies on board.
Length: 2,098.9 feet (639.75 meters)
Height: 672.5 feet (204.97 meters)
Width: 1,865.0 feet (568.44 meters)
Mass: 4.215 million metric tons (Deep Space Nine: Technical Manual)
Power System: Anti Matter with 15 year life span. Ship normally only goes 5 years between the ship being refueling.
Cargo: Cargo holds are scattered about the ship that allows for carrying up to 500,000 tons of cargo in addition to standard compliment of supplies and ammunition.
Market Cost: 28 billion to construct.
- Heavy Polaron Beam Emitters (3): This weapon is incredibly
powerful and is capable of doing considerable damage to large targets.
The weapon will inflict double damage to all shields that have not been
modified to operate against these weapons. The weapon is mounted near the
front of the ships but can rotate up to 20 degrees of axis to be able to
fire at targets. The weapon fires a long continuous beam at the target
similar in appearance to standard phasers fire.
Maximum Effective Range: 93,300 miles (150,000 km) in space and 93.3 miles (150 km) in an atmosphere.
Mega Damage: 2D4x1000 each or 4D4x1000 for both beams combines.
Rate of Fire: Twice per melee per cannon
Payload: Effectively Unlimited.
- Polaron Beam Emitters Turrets (16): This weapon is incredibly
powerful and is capable of doing considerable damage to larger targets
and is the same type of mount as is carried on the Attack ship but are
in singe mounts in turrets. The weapon will inflict double damage to all
shields that have not been modified to operate against these weapons. The
weapon fires a long continuous beam at the target similar in appearance
to what standard phasers fire. Weapon can fire a low powered beam against
fighters with half penalties to hit fighters or can fire a high powered
beam that is capable of doing significant damage to large ships but has
standard penalties to hit small targets.
Maximum Effective Range: 12.4 miles (20 km) through atmosphere and 12,400 miles (20,000 km) in space.
Mega Damage: Low powered beam: 1D6x100 each (Half penalties to strike small targets), Full powered beam: 3D6x100 each (Full penalties to strike small targets)
Rate of Fire: Maximum of Four (4) times per melee each cannon.
Payload: Effectively Unlimited.
- Four (4) Photon Torpedo Launching System: Two of launcher
is mounted in the front of the Battlecruiser and two launchers are mounted
on the afct of the vessel.
Effectively very similar to Phase World cruise missile launchers but instead of having groups of multiple launchers, the Dominion has concentrated on launchers that can launch more than one torpedo at the same time. Once spread of torpedoes has been launched, the launchers must reload and rearm before launching another spread of torpedoes.
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 - 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 (Anti-matter warheads) do 4D6x100 M.D.C. each
Rate of Fire: One at a time or in volleys of 2 or 4. Launcher is reloaded on the same melee and can be fired again on the next.
Payload: 100 Photon torpedoes per launcher for 400 total.
- Cloaking Device Penetrator: The Dominion ship, while not carry
a cloaking device itself, has a special system to detect cloaked ships.
The system works by using a relatively narrow energy beam that disrupts
the cloaking device. The ships sensor operator uses his read sensory equipment
roll with a -10% to the skill roll, if the operator succeeds then the cloaked
ship will be detected and can be targeted with a -2 to the strike roll.
The systems does not work against cloaking methods other than those system
that work on a similar principle to the Romulan Cloaking Device. This system
will also not work on any magical cloaking methods.
Range: 62,200 miles (100,000 km) in space and 622 miles (1000 km) in an atmosphere.
