The writeup of the U.S.S. Defiant is designed to be used during the later Star Trek: Deep Space Nine and Star Trek: Voyager episodes.
The USS Defiant is a starship built to a different set of standards to most starships in the Federation. She was built as a combatant starship and does not have large amount of space allocated for crew quarters although crew quarters are still spacious when compared to modern naval vessels. The ship design was designed to fight Borg cubes using large squadrons but according to the first episode that the USS Defiant was introduced, the program was scrapped. The U.S.S. Defiant herself was put into mothball status due to some problems with the design. The ship program was continued after the beginning of tension between the Federation and the Dominion but the class has only been produced in small numbers. The reasoning for this is unknown and many senior officers strongly disagree with this and want a large number of this class produced. At least one Star Trek novel indicates that more than one Defiant class and several voyager and next generation episodes has indicated that more than just the U.S.S. Defiant has been built.
The ship class has proven its worth several times and is one of the most effective ship in the Federation fleets. In several battles, the U.S.S. Defiant has been used at the spear point in major battles. Later, the U.S.S. Defiant was destroyed but another ship was renamed to replace her.
The Defiant class does not fight like most cruisers but instead fights much like a fighter but has far more firepower than any fighter ever produced. The main firepower of the ship are pulse phasers that point forward on the vessel. These weapons are cable of doing severe damage to larger vessels and completely destroy ships in one shot. The ship is very well protected with shields and later in the ships service, the ship had ablative armor added to the outside of the vessel. The U.S.S. Defiant carried a Romulan cloaking device until it was destroyed. While that ship was allowed to carry a cloaking device due to a special arrangement with the Romulan government, the Federation can produce their own cloaking devices or can purchase them from the Klingons.
The U.S.S. Defiant, if defined by Phase World terms, would be considered to be a light cruiser by the ships size and mass. The ship has very powerful beam weaponry compared to phase world ship that are the same size, but her missile weaponry is not as heavy as most starships of the Three Galaxies and she does not have a large amount of point defense.
This design is written to be able to interact with modified phase world rules. See Revised Starship Rules for Phase World 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: NX-74205
Vehicle Type: Escort/Attack Corvette (Light cruiser by Phase World terms)
Crew: 75 although ship can be crewed by 8 crew members in emergencies
Troops: 50 Marines
Vehicles: 2 Small Shuttles
M.D.C. By Location:
| Main Body (Primary Hull):||45,000 / 30,000 before ablative armor was added|
|Warp Nacelles (2):||15,000 each / 10,000 each before ablative armor was added.|
|Photon/Quantum Torpedo Launchers (4):||1,000 each|
|Pulse Phaser Arrays (4):||600 each|
|Conventional Phaser Arrays (2):||600 each|
| Variable Force Field:||8,000 per side (48,000 total)|
 Depleting the MDC of the main body will put the Defiant out of commission. All internal systems will shut down, including life support and internal gravity. The ship itself will be an unsalvageable floating wreck.
 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 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.
 Shields positions can be varied and all could be combined in one shield. Shields regenerate at the rate of 5% (2,400 MDC) 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 1.2 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: Maximum speed is Mach 10. using impulse engine. Due to starship having gravitic propulsion systems, starship can enter and leave the atmosphere.
Stardrive: Uses a warp engine that allow ship to travel at Warp Factor 8.8 on cruise (0.16 light years per hour), Warp Factor 9.4 Flank (0.2 Light Years per hour), and Warp Factor 9.982 Emergency (0.68 Light Years per Hour). Speed is calculate using a formula designed to emulate Star Trek: Next Generation speeds. 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. Ship carries about two years worth of supplies on board.
Length: 560.0 feet (170.68 meters)
Height: 98.8 feet (30.10 meters)
Width: 440.0 feet (134.11 meters)
Mass: 355,000 metric tons (Deep Space Nine: Technical Manual)
Power System: Anti Matter with 5 year life span. Ship normally only goes 2 years between refuelings.
Cargo: Very Small, Cargo holds are scattered about the ship that allows for carrying up to 400 tons of Cargo in addition to standard compliment of supplies and ammunition.
Market Cost: 8 + billion to construct. As far as it is known, the Federation does not sell their starship designs to other interested parties.
