Like all the equipment and materials aboard the ship, the mess hall was spartan and compact. At the head of the room were three open slots that served as dispensers for the replicators. A counter extends from the underside and is used for the placement of trays, mugs and eating utensils. Seating inside the mess hall is provided by four metallic tables arranged in a semicircle at the wider end of the room.
These tables are approximately one meter square, and each has four stools connected to its legs. In addition, the mess hall doubles as a makeshift meeting area that could be used to conduct crew briefings and mission profiles.
A tall screen panel located on one of the walls can be used as a visual aid to display tactical graphics. The current version of the Defiant-class vessel is equipped with one main shuttlebay and two auxiliary bays that double as exterior access hatches for Cargo Bays 1 and 4. Shuttlebay 3 is a recent addition that has now become standard on the Uprated version of the Defiant, and houses a single Type Shuttlecraft and the facilities to maintain it.
This two-story bay is located on Decks 2 and 3 directly beneath the main bridge in an area originally intended to house future weapons stores and computer upgrades. Two horizontal sliding hatches on the ventral side of the ship allow access to space while a ceiling-mounted tractor beam holds the shuttle in position for launch as the doors open. The Deck 2 portion of the bay features a flight control booth that serves as the nerve center for shuttle operations.
This room also controls the doors of the other shuttlebays as well as having direct control of the main tractor emitters should a damaged shuttle need to be towed in. Force field emitters throughout the bay ensure that atmospheric integrity will not be lost, even when the bay doors are open.
Type: Medium short-range sublight shuttle. Accommodation: Two; pilot and system manager. Power Plant: Two millicochrane impulse driver engines, four RCS thrusters, four sarium krellide storage cells.
Dimensions: Length, 4. Mass: 1. Armament: Three Type-V phaser emitters. Developed in the mids, the Type Shuttlepod is somewhat of a departure from the traditional layout for ships of its size.
In response to the growing threat of conflicts with various galactic powers bordering or near to the Federation, this shuttlepod was designed to handle more vigorous assignments that still fell into the short-range roles of a shuttlepods. Even with her parent vessel under attack, the Type was designed to function in battle situations and could even be used as an escape vehicle should the need arise.
Lacking a warp core, the pod is a poor choice for travel beyond several million kilometers. Ships of this type are seeing limited deployment on various border patrol and defensive starship classes, including the Defiant-, Sabre-, and Steamrunner-class.
Type: Heavy long-range warp shuttle. Accommodation: Two flight crew, two passengers. Power Plant: One cochrane warp engine, two millicochrane impulse engines, four RCS thrusters. Dimensions: Length, 9. Mass: Performance: Warp 5. Armament: Three Type-V phaser emitters, two micro-torpedo launchers, jamming devices. Developed specifically for the Defiant-class starship project, the Type Personnel Shuttle is the largest departure from the traditional role of an auxiliary craft that Starfleet has made in the past century.
Short of a dedicated fighter craft, the Type is one of the most powerful auxiliary ships, with only the bulkier Type being more heavily equipped. Nonetheless, the shuttle sports increased hull armor and the addition of micro-torpedo launchers, as well as a suite of tactical jamming devices.
A larger warp coil assembly, as well as torpedo stores, makes the Type much more heavier then other shuttles. Elements from the Defiant-class project that were incorporated into the shuttle include armored bussard collectors, as well as a complex plasma venting system for use during possible warp core breech situations.
This bulky craft is equipped with a powerful navigation deflector that allows it to travel at high-warp, and a complex sensor system makes this shuttle suitable for reconnaissance work.
Able to hold its own in battle situations, the Type is seeing limited deployment on Defiant-class starships, as well as border patrol vessels and combat-ready ships. Type: Utility craft. Accommodation: One operator. Armament: None. The Work Bee is a capable stand-alone craft used for inspection of spaceborne hardware, repairs, assembly, and other activates requiring remote manipulators.
The fully pressurized craft has changed little in design during the past years, although periodic updates to the internal systems are done routinely. Onboard fuel cells and microfusion generators can keep the craft operational for If the pilot is wearing a pressure suit or SEWG, the craft allows for the operator to exit while conducting operations.
Entrance and exit is provided by the forward window, which lifts vertically to allow the pilot to come and go. A pair of robotic manipulator arms is folded beneath the main housing, and allows for work to be done through pilot-operated controls. In addition, the Work Bee is capable of handling a cargo attachment that makes it ideal for transferring cargo around large Starbase and spaceborne construction facilities.
The cargo attachment features additional microfusion engines for supporting the increased mass. It should be of little surprise that the Defiant-class is a spaceframe designed primarily for tactical and defensive operations, and thus, its primary mission types are rather one-sided when compared to most other ships that serve in the Federation fleet.
While this may appear to be short-sided of the Defiant, recent evidence suggests that continued hostilities between the Federation and threat forces means that tactical mission types will never be in short supply. The following are the primary mission types for the Defiant-class vessel:.
The listed mission types are by no means the only operations that Defiant-class vessels are capable of performing. Even after the initial testing of the NX pathfinder vessel, Starfleet continues to run projections on possible mission types.
The normal flight and mission operations of the Defiant-class starship are conducted in accordance with a variety of Starfleet standard operating rules, determined by the current operational state of the starship.
These operational states are determined by the Commanding Officer, although in certain specific cases, the Computer can automatically adjust to a higher alert status. During all modes of operation, the ship runs on four six-hour shifts designated Alpha, Beta, Gamma and Delta.
In extreme circumstances, a Defiant is capable of landing on a planetary surface by making use of four retractable struts built into Deck 4. Originally designed to allow a ship to set down in a large landing bay within a starbase. Any planetary bodies with a higher gravity will result in the starship being unable to escape its gravity well.
With all available power routed to both the SIF and IDF, the ship is capable of making a controlled landing, preferable on a flat and stable surface. Automated computer algorithms have been preprogrammed to allow greater ease of control for the flight control officer.
Taking off from a planetary body requires much more effort then landing. All secondary and most primary systems must be taken offline to provide further power to the impulse engines and RCS thrusters. The already overrated engines of the Defiant-class require that the ship be launched in a near-vertical manner.
SIF, IDF and gravity systems are brought to full enable while all other systems, including life support, are taken offline for the duration of the launch. Seeing as the process typically takes only a few minutes, there is sufficient breathable air still in the system during the entire process. Aside from the escape options provided by the onboard shuttlepods, the principal survival craft is the Starfleet lifeboat, or escape pod.
The current lifeboat is sized to include two main types, a six-person and an eight-person version. Defiant-class vessels carry twenty-six of the six-person types, which measure 3. Each lifeboat contains enough consumable and recycling capabilities to keep the crew alive for eight months, longer with multiple lifeboats connected in standard "gaggle mode. These units have been specially modified for low-observability and minimal EM signatures due to the general wartime conditions.
Rescue and evacuation operations generally fall into two categories, rescue and evacuation to the ship, and evacuation from the ship. The former will generally involve transport from another ship or planetary surface. The latter will generally involve removal of the ship's company to another ship, a planetary surface, or into space.
Due to the nature of the Defiant, its ability to perform in evacuations is hindered by the limited amount of space onboard, as well as the small number of transporters available. With the cargo transporter reconfigured for quantum resolution transport, the Defiant is capable of beaming aboard persons per hour.
The Type shuttlecraft onboard is also capable of assisting in evacuations, however, the shuttlepods are ill-equipped to render such need. As the Dominion War had indicated, it is quite conceivable that a starship may be lost in battle or due to other unforeseen circumstances. While Starfleet general policy dictates that all efforts must be made to save a starship, situations sometimes warrant the total evacuation of a ship.
As stated before, Defiant-class vessels are capable of transporting persons in one hour. Unlike most Federation starships, Defiants lack dedicated emergency transport systems.
Instead, they rely heavily on escape pods to evacuate the ship. In addition, all four shuttlepods and the Type shuttlecraft are brought to full operation and are capable of carrying personnel from the ship.
After the computer has acknowledged that all personnel have cleared the ship, it begins to lock out all major command functions so that information cannot be stolen from the ship should a hostile vessel board a Defiant before a salvage team can make it to the site. Automated distress beacons are launched shortly after. At the time of this writing, computer simulations suggest that the Warhead section could be used as an escape vehicle if that portion of the ship isn't severely damaged.
The following starships have been commissioned by the Federation:. Officers and Crew: 40 Evacuation Limit: Overall Length: Maximum Velocity Warp: 9. Standard - 4 Pulse Phaser Cannons, 2 forward torpedo launchers, 2 aft torpedo launchers Uprated - 4 Pulse Phaser Cannons, 1 forward torpedo launcher, 2 aft torpedo launchers. Deck Layout for Uprated Variant:. This is the one point in this entire page where you'll find that, for the first time, I've stepped out of the Star Trek universe and back into our own 21st Century mindset.
The information presented on this page is a result of hours and hours worth of researching, more researching and then a rigorous and intensive process of compiling the best information from canon sources, and making an attempt to fill in the blanks. Now to address some of the problems found in compiling this information, followed by a brief explanation as to why a certain path was taken in these specs. Defiant History: Why does it seem that the history of the Defiant has just been cut and pasted from many sources?
Because it is, all of them being considered canon or semi-canon sources. The history of the starship classes that we create are made to coincide with what is seen on screen, and it is not or duty to rewrite what has already been established without just cause.
The history of the Defiant has already been written by a handful of people, all of which are either staff members involved with the production of Deep Space Nine or under authorization from Paramount to do so.
There are not many places left in the ship's history to allow for useful writing that would benefit the readers of these specifications without dipping too deep into the realm of fiction.
Our main concern is that neutro m ium has a very similar spelling to neuto n ium. Nonetheless, it isn't mentioned anywhere else, which leaves us to believe it is some sort of exotic substance. Still, to cover our butts, Steve suggested that we say the original NX hull had what the ST: Magazine said, and all production line ships are of a more standard type. Size of the Defiant: This is perhaps one of the most widely debated topics when it comes to this starship.
As it turns out, backstage information tells us that this ship was designed with no real size in mind, which is why you'll find no identifying marks on the studio model in terms of windows and airlocks; things that would give away the true size of the ship.
The DS9 Tech Manual states that the ship is The master systems display seen in engineering and throughout the ship was designed with a meter length in mind and in addition, the sizes of the living quarters, sickbay, mess hall and various other studio sets further support the meter design.
The two foldout schematics of the Defiant at the back of the DS9 TM also are made around a meter model as well. The purest canon is considered to be the actual onscreen evidence, and therefore, I assume that the Defiant is meters in conjunction with that evidence.
The relatively recent publishing of the "Starship Spotter" also supports this size. The only support for a Decks 5 and 6 is the appearance of several portholes at the back underside of the Defiant model, but we do not know for sure if these are windows or possibly something else. Because we see more references to a 4 Deck version of the ship as opposed to a 5 deck, I've concluded that the ship only has 4. Torpedo Launchers: Throughout DS9 we've always seen the Defiant launch torpedoes from the targeting weapons sensor pods near the front of the ship.
The DS9 TM and MSD like to tell us that the forward torpedo launcher is located just beneath the main deflector at the front of the ship. This seems to make sense with the Warhead module, which is said to be able to detach from the Defiant and act like a mobile torpedo. If the torpedo launcher were located in the front, then the torpedo magazines for the forward launcher would add to the Warhead's destructive power.
MSDs show that the ship has two aft torpedo launchers, which makes sense even if the DS9 TM says there's a total of 2 launchers on the ship. It also says the Galaxy-class has two launchers, but we know for a fact that a third launcher is located in the saucer section as stated in the TNG TM.
You'll notice that the torpedo launcher anomaly is discussed in these specs, and appropriate cover-ups and explanations are included for the two variants. Well, it needs to be called something Phantom Phaser Arrays: Several times we saw Defiant-class ships fire a standard phaser beam blast from the upper area of the ship, close to the Main Bridge.
While on the model we can see two strip-like objects on the upper hull, the phaser blasts seen onscreen are not anywhere near those pseudo-emitters. It was a rare occasion to see a blast from that area, so we're assuming that those ships were perhaps outfitted with a special test module to see if it was feasible to mount standard phaser strips on the Defiant.
Probes: Obviously, the Defiant is simply too small to allow for it to be equipped with all the known types of probes listed in the Star Trek: The Next Generation Technical Manual. Since the ship already carries a number of photon and quantum torpedoes, the Class VIII and Class IX are the only known types that make use of the same casings.
Switching out a warhead with a sensor package takes only a few minutes, and saves a lot of space; especially when the components for the sensor package can be replicated, while the warhead and warp sustainer coils cannot.
This was on loan from the Romulan government, and treaty stipulations still apply for all other starships. Bottom line, no other Federation starships can legally use a cloaking device until we hear onscreen that revisions have been made to the Treaty of Algeron.
Warp Core Ejection Systems: So far, I've yet to see a hatch on the underside or topside of the ship that suggests the warp core can be ejected. Martin next turned to more traditional starship designs, but Zimmerman told him that a completely new look was needed, like nothing ever seen on Star Trek before. Ultimately, Martin went to a design he had done for a Maquis fighter for the episode " The Maquis, Part II ", and he brought it to the producers, who approved it as the basis for the Defiant -class.
After tweaking the design a little, Martin gave the schematic to model maker Tony Meininger who, along with his Brazil Fabrications , was given the nod to bring the design to life. The main problem with the design at that stage was that it didn't look fast enough, so Meininger, a car enthusiast, got some posters of Ferraris and used them to help him design the "streamlined" look of the ship, making it very compact and sleek.
It was to be an entirely new ship. For DS9, a digital model of the Defiant was built by Digital Muse , which was then borrowed by the visual effects artists of Star Trek: Voyager , as and when required. Cinefantastique , Vol. Stock visual effects shots were used for both the prototype USS Defiant and its substitute. According to Hutzel, during the early development stages of the ship, the Defiant was to be " a new hot battleship that would really set a new standard for an action ship in the series.
First, there was lots of talk like 'How big is the Defiant? According to Doug Drexler , " The size of the Defiant was a hot potato from day one.
Rick Berman wanted a small pocket battleship a couple times longer than a runabout, with the girth of a regular starship , Gary wanted at least ' [ This was also the size established in the DS9 Technical Manual. The original MSD that appeared in " The Search, Part I " actually depicted an early concept design and did not represent the final iteration. Initial drawings described the class as the Valiant -class.
Indeed, Drexler even constructed an initial dedication plaque for the Defiant that referred to it as the " Valiant -class," before a new plaque was recreated that simply stated "the first ship of her class. The interior sets of the Defiant were supervised by Herman Zimmerman. According to regular background performer Brian Demonbreun , there were special carpets transferred onto the "normally" seen carpet of the Defiant in scenes including explosions and sparks.
All actors, mostly the background performers, who were near those sparks were made wet, with a light moisture film on their hair and uniform.
The tight physical restrictions influenced Friedman to watch old World War II films involving "people sitting in cockpits," in an effort to increase her familiarity with methods employed when shooting in constrained places. Another issue was that, since the cloaking device was initially only meant to be used during the "The Search" two-parter, the set was not made with variable lighting; all the light bulbs had to be manually changed by stopping filming whenever the cloak was used.
When the cloak was kept, this made filming nightmarish and reshoots an exercise in hurry up and wait. Subsequent alterations to the Defiant bridge set made it a lot easier to film in.
Third season DS9 finale " The Adversary " introduced a Defiant -class engine room and mess hall, which were created as standing sets. Ronald D. Moore was highly pleased with the addition of the new sets. The same sets were used for both the Defiant and the Valiant.
They know you are just using the same sets again, and it gets a little boring. The notched forward hull containing the vessel's navigational deflector and main sensors was a detachable single-use last-resort missile. This missile was equipped with a small impulse engine and a magazine with six torpedo warheads. These torpedo warheads were part of the ship's auto-destruct system and under more normal circumstances could be fired from the forward launcher.
Any torpedo warheads left in the magazine would become the missile's warhead upon the missile's separation from the rest of the ship. If no torpedo warheads remained, then the missile would have to rely on kinetic energy alone. The ship would be unable to travel at high warp speeds without the missile since the latter contained the ship's navigational deflector.
During the mission "Ambush" in the game Star Trek: Legacy , the USS Defiant was sent to the Etarian Nebula for a test flight of its systems, where the crew found that the Romulans had invaded the nebula waiting for a fugitive. The Monitor boasted several modifications from a standard Defiant -class starship, such a cloaking device and black sensor reflective hull plating.
Its warp engines were tuned so the nacelles would emit ultraviolet light instead of the standard red and blue, and the ship had no running lights or hull markings.
In Shatner's novel The Return , the Monitor is temporarily renamed Enterprise during a mission to the Borg homeworld using a stolen transwarp drive , commanded by Captains Kirk , Picard , and Spock. Star Trek Online has Defiant -class vessels available for characters who reach Captain rank or higher as a Tier 4 "Tactical" Escort or Tier 5 "Tactical Escort Retrofit" the difference being that the Tier 5 variants come equipped with cloaking devices.

In the first draft script of " The Dogs of War ", the Defiant -class was established as being capable of warp 9. It is of note that soon after the cloaking device was brought into use, the Dominion developed a way to penetrate the cloak using certain types of antiproton beams. The Defiant was especially vulnerable as the power of the warp engines in relation to the size of the ship led to a high power signature that wasn't fully masked by the cloaking device.
It did, however, at times provide a significant tactical advantage that was exploited on numerous occasions. DS9 : " The Search, Part I " This issue was later resolved, indicating that a modification was developed to defeat this detection method. A "Deck 5" was mentioned in dialogue three times during the fourth season : in " The Way of the Warrior ", " Rejoined " and " To the Death ".
The first two citations were in reference to hull breaches ; the third had Captain Sisko traveling to "Deck 5, Section 1" via turbolift. At the end of DS9 Season 5 , the Defiant -class engineering set was deemed to be taking up much-wanted room in the swing set area of the Paramount sound stages used by Star Trek: Deep Space Nine.
This resulted in the set for an overhead flying rig — originally built and used for Season 2 installment " Melora " — to be removed from that stage. Another transporter room on the Defiant -class. This location was identified in the episode's script.

The Defiant -class was a type of Federation starship in use by Starfleet from the 24th century into the 25th century. Although officially designated as an escort , the Defiant ships were the first type of starship Starfleet ever created as a dedicated-purpose warship , and they are sometimes referred to as destroyers.
The Defiant was conceived as Starfleet's first warship in response to the many new threats faced by the Federation in the midth century but primarily the Borg. As more conservative elements of Starfleet began to worry of the Federation encountering hostile societies and the fear it's defenses were antiquated, the need for greater defensive capability was recognized.
The vessels were purposed as a compact design, utilizing components typically installed aboard larger starships and packing a great deal of weaponry into a otherwise small, maneuverable ship.
As such, many of these vessels were fielded in battle during the Dominion War. The class has a compact warp core that produces enough energy to power a vessel four times its size. The Defiant -class was one of many new Starfleet classes developed in response to the Borg threat following Starfleet's tragic losses in the Battle of Wolf The class was the first that Starfleet ever developed purely as a warship—but for years following the Borg's early incursions, the expected invasion never materialized—the prototype USS Defiant spent much of its time in space dock in the Utopia Planitia Fleet Yards.
Various design flaws creeped up in the build, namely the ship is overpowered for a ship it's size; structural integrity was insufficient and the vessel nearly tore itself apart at maximum warp. Rising hostilities with the Dominion spurred the Defiant into full service, assigned to Deep Space 9 in and fitted with a Romulan cloaking device to defend the station from Dominion attack and conduct undercover operations in the Gamma Quadrant.
During this operational period, many of the earlier design deficiencies were corrected. In response to rising hostilities from the Dominion, the Borg, the Maquis, the Breen and the Cardassians, the Defiant -class was authorized for production and several more were ordered. By the time the situation escalated into full-scale war, several Defiant -class starships had been put into service and had performed admirably. Following the Dominion War Starfleet developed a ship based on the lessons of the Defiant -class, the first and so far only vessel of this type, the USS Incursion is fitted with a holographic masking system and is operated by Starfleet Intelligence.
