The Intrepid-class starship is a Federation design that entered service in the latter half of the 24th century. At less than half the size of a Galaxy-class starship, the Intrepid-class is considered "quick and smart."

General Overview

When first commissioned, the Intrepid-class featured many innovations then becoming available, not least being the tricyclic input manifold of the warp core and variable-geometry pylons. The class is also the first to incorporate bio-neural gel packs and is equipped with the Mark 1 Emergency Medical Hologram system.

Capabilities upon introduction are equally impressive. The class boasted the best navigational sensors, and the highest top speed of any Starfleet vessel until the development of the Prometheus-class. Its multi-mission design is backed up by a main computer processor capable of simultaneously accessing 47 million data channels and sustaining 575 trillion calculations per nanosecond in operational temperatures from 10 Kelvin to 1790 Kelvin.

Class History

Voyager in drydock at the Utopia Planitia Fleet Yards

Development and construction of the Intrepid-class occurred at the Utopia Planitia Fleet Yards with the class entering service by 2370. The second ship, USS Voyager, is commissioned in 2371. She is the first ship to test the class 9 warp drive in deep space.

The performance of the Intrepid-class is well reflected by Voyager. That ship is notable for independently, and successfully, completing an unscheduled seven-year journey across the previously unexplored Delta Quadrant, 70 thousand light years from Federation space, from 2371 to 2378. The vessel is completely cut off from communication with Starfleet until 2374, and has no access to any Starfleet supplies or facilities for the entire length of its journey

Technical Data

Physical Arrangement

The hull configuration of the Intrepid-class adopted the saucer-type shape of previous starship classes, that of primary hull, secondary hull, and nacelles driven by the physics of warp generation and control. One of the Intrepid-class' most notable characteristics are its warp nacelles, which angled when going to warp, a quality which has not been observed in any other starship. The Intrepid-class used a duranium hull structure, a plasma-based power distribution system, and tricyclic life-support systems.

Following the Starfleet standard, Deck 1 is reserved for the main bridge, with the briefing room and captain's ready room located to port and starboard sides of the bridge. Located in the front section of Deck 2 is the crew's mess hall and the Captain's private dining hall, served by three windows that offered a spectacular view of space in front of the vessel. One deck below, located in the front section of Deck 3, are the quarters of the starship's commanding officer, served by five windows.

The dorsal saucer section is covered by four phaser arrays, two of which extended from the aft curvature along the length of the saucer and. The aft firing arc is covered by two smaller arrays, angled on the rear of the saucer section. The relative bottom of the ship is protected by two similar arrays as on the dorsal saucer section, extending to the rear of the saucer and following the curve towards the bow. Docked to the underside of the Intrepid-class' primary hull is the vessel's aeroshuttle.

Further aft, the main navigational deflector dish is found at the foreside of the Intrepid-class' secondary hull. Located right above the deflector are the forward photon torpedo launchers. On the underside of the secondary hull are located three sets of plates that support the warp propulsion system. The forward plate covered the reserve intermix chamber; the middle plate contained the antimatter loading port, a large magnetic valve that kept the antimatter from coming in contact with matter during the transfer to the storage pods; and the aft cover plate contained the operational intermix chamber hatch, for ejecting the warp core in case of emergency.

One of the few Starfleet starship classes capable of atmospheric entry and planetary landing, the Intrepid-class starship is equipped with antigravity generators as well as impulse and lifters strategically placed at the mass and stress points on the bottom portion of the secondary hull. Prior to and during landing or takeoff procedures, the vessel typically went to blue alert, indicating to the crew they are to assume their code-blue stations.


With 15 decks and a mass of 700,000 metric tons, there are 257 rooms on a Intrepid-class vessel.

Command and Control Systems

//Intrepid//-class main bridge

The main bridge of the Intrepid-class starship is ovoid and served as the nerve center of the vessel. At the bridge's rear is a large bank of consoles and data readout screens. Center of that area is the master systems display; control consoles flanked it on both sides.
Starboard of the information center, past the starboard side turbolift, is the station of the chief tactical officer. This area is maintained mostly for internal security and combat situations. Other systems that could be commanded by tactical included long- and short-range sensor arrays, sensor probes, message buoys, and tractor beams. An identical station is found on the other side of the bridge, where the operations console is found. This panel presented the operations officer with a continually updated list of current major shipboard activities. This list permitted Ops to set priorities and allocate resources among current operations. This is especially critical when two or more requests required the use of the same equipment, entailed mutually exclusive mission profiles, or involved some unusual safety or tactical considerations.

Section of the //Intrepid//-class captain's ready room

Forward of the upper ship operations areas are doorways to the briefing room at one side and the captain's ready room at the other. There, the commanding officer could engage in administrative work with all relevant office equipment at hand without interfering with bridge operations. Also, this room is usually the preferred place where the captain could hold private discussions or receive classified communications. Aboard the Intrepid-class starship, the work desk is the focal point of the ready room, located ahead of the main entrance door. A raised level in the forward section of the room featured a small table, a curved couch, and a replicator. The wall behind the couch featured three windows looking toward the bow of the vessel. Compared with the much larger Galaxy-class starship, the Intrepid-class curiously has a more spacious, luxurious ready room.

The chairs of the captain and first officer on the //Intrepid//-class bridge

In the center of the Intrepid-class' bridge is the command area. Here, seating is provided for the vessel's commanding officer and his or her first officer, seated to the captain's left. Between these chairs is a miniaturized status display. Using keyboard or vocal commands, the commanding officer could use these controls to override the basic operation of the starship. Directly aft of this area, integrated in the handrail encircling the aft section of the central command area, is another command console that could be operated to perform more bridge duties.

Directly forward of and two steps lower than the central command area is the conn station. From here, the flight control officer served as helmsman and navigator for the starship. Despite many of these functions being heavily automated, their critical nature demanded a humanoid officer to oversee these operations at all times. During spaceflight at impulse, conn monitored relativistic effects as well as inertial damping system status. When the ship is traveling at warp speed, conn monitored the subspace field geometry in parallel with the engineering department. During warp flight, the conn console continually updated long-range sensor data and made automatic course corrections to adjust for minor variations in the density of the interstellar medium.

To the right of conn sat the chief engineer. Though the position is far better served in main engineering, situations arose where the engineer's presence is needed on the bridge. The console allowed complete control over all engineering systems. Directly opposite sat the chief science officer at a similar console.

Propulsion Systems

Main Engineering

Main engineering aboard an Intrepid-class starship is located on Deck 11. The room is constructed around the matter-antimatter reaction assembly warp core, a class 9 warp drive with a tricyclic input manifold. The core provided a maximum output of 4,000 teradynes per second. The warp drive allowed the ship a top sustainable cruise velocity of warp factor 9.975. The Intrepid-class also featured a secondary warp assembly.

The main engineering room featured two levels. In front of the warp core is a large monitoring area on the lower engineering level. Also located on this level is the chief engineer's office and an open work area for special projects or situational analysis. A second tier ringed the upper level of main engineering. A small, single-person elevator, as well as a ladder on the opposite side, provided access to this catwalk.

The class 9 warp core of an //Intrepid//-class starship

The main impulse engines on an Intrepid-class starship are located on the aft end of the pylons leading to the warp nacelles. Intrepid-class starships are also equipped with auxiliary impulse reactors.

Warp Core Ejection

n the event of a warp core breach, the Intrepid-class starship could eject the warp core. This procedure required the authorization code of the chief engineer or a member of the senior staff. The core is ejected through the ejection port on the underside of the secondary hull. Magnetic rails inside the channel accelerated the core once disengaged from the vessel and fired it away from the ship. Under normal circumstances, the vessel then moved away from the core as fast as possible under impulse power.

Should the core not go critical, the vessel could recover it with tractor beams and careful manipulation.

Tactical Systems

Phaser Systems

An //Intrepid//-class starship firing its phasers

The Intrepid-class utilized a ship-mounted phaser array system. The dorsal saucer section is covered by four phaser arrays, two of which extended from the aft curvature, along the length of the saucer and stop short of the auxiliary deflector incision. One smaller phaser array extended behind the bridge. The aft firing arc is covered by two smaller arrays, angled on the rear of the saucer section. The relative bottom of the ship is protected by two similar arrays as on the dorsal saucer section, extending to the rear of the saucer and following the curve to the auxiliary deflector incision. More protection is provided by an array that extended across the ventral engineering hull just fore of the warp core ejection port. Far-aft strips are provided on the underside of the variable-geometry nacelle pylons and under the shuttlebay landing deck on the underside of the ship for a total ship's complement of fourteen phaser arrays.

Additional phaser banks included at least four separate phaser emitters, two in the aft torpedo launcher, one aft phaser bank located behind the second tractor beam emitter, in the aft section of deck 14, and an embedded emitter on the ventral surface of the ships right nacelle.

Torpedo Systems

The Intrepid-class housed five standard torpedo launchers (two fore and two aft, and one on the dorsal side of the ship ). The USS Voyager is loaded with type-6 photon torpedoes in 2371. She also has at least four class-10 photon torpedo warheads and two tricobalt devices in her torpedo arsenal, as well as spatial charges. Cardassian quantum torpedoes are also compatible with Intrepid-class launchers, with some modification.

Deflector Shields

The //Intrepid//-class' deflector shields react under incoming fire

The Intrepid-class' deflector shield is a symmetrical, oscillating subspace graviton field. During combat, the shield sent data on what type of weapon is being used on it and what frequency and phase the weapon used. Once the tactical officer analyzed these data, the shield could be configured to have the same frequency as the incoming weapon, but different nutation. This tactic dramatically increased shield efficiency. There are a total of fourteen shield grids on the Intrepid-class.

Tractor Beam

Each Intrepid-class tractor beam emitter is directly mounted to the primary members of the vessel's framework. The forward emitter is located on the underside of the secondary hull under the main deflector dish. The second emitter is located at the aft end of the secondary hull in the aft section of Deck 14.

Crew Support Systems

Medical Facilities

The main ward

There is one large sickbay facility located on Deck 5, equipped with an intensive-care unit (ICU), biohazard support, critical care, a morgue, the chief medical officer's office, a load-out of three standard biobeds and one surgical bed in the main ward, and a small medical laboratory. The standard medical staff consisted of a doctor and a nurse, supplemented by the Emergency Medical Hologram, the Intrepid-class being one of the first to be equipped with this medical technology.

The intensive-care unit

Three biobeds lined the walls of sickbay's ICU; these are for patients receiving medical care and are equipped with biofunction monitors. Located in the corner of the main ward is a surgical bed, where major surgeries are performed and critical patients are treated. A large, sophisticated sensor cluster is installed in the ceiling directly above this bed. Working with a medical tricorder, the sensor suite could give detailed information about a patient's condition. The bed is also designed to use a surgical support frame. The small area that the surgical bed is located in could be isolated by a force field. If necessary, surgery could be conducted in the intensive care ward if there is an overflow of patients or if another patient is present to donate blood.

Located in the center of the sickbay facility is the chief medical officer's office. Here, the CMO is provided with an area to work in privacy or conduct meetings with patients, staff, and others. Its proximity allowed the CMO to be present in sickbay almost immediately. Located behind this office is a small medical laboratory facility. The medical staff or other associated personnel could monitor experiments or run tests here during their duty shifts. Just off the medical lab is located a tiny area for storage of the deceased.

Recreational Facilities

Crew mess hall on board an Intrepid-class vessel

There are two holodecks aboard the ship. Located on Deck 6, these holodecks are proprietary Federation technology and could comfortably support fifteen people at a time. The Intrepid-class' holodecks are of a next generation of holographic technology, even further advanced than those applied on board Starfleet vessels during the 2360s, being able to impersonate matter even at the molecular level.

On the Intrepid-class vessels, the mess hall is on Deck 2, Section 13. Some ships are equipped with four food replicators, with a private captain's dining room just behind the mess hall. This dining room could be reconfigured to serve as a kitchen, as done by Neelix aboard Voyager. The USS Vanguard's mess hall is also fitted in this manner.

The mess hall is typically host to many social gatherings, including diplomatic affairs, birthday parties, and holiday celebrations. The mess hall could also serve as a makeshift sickbay whenever that facility is disabled or otherwise overwhelmed.

A crew's lounge is located in the far aft section of the vessel's secondary hull, providing a view of space aft of the Intrepid-class starship.

The Intrepid-class also has a gymnasium.

Crew Accommodations

All crew and officers' quarters (except the captain's quarters on Deck 3) are located on decks 2, 4, 8, 9, and 13, with special variable environment quarters on Deck 11 for crew with special comforts. Although the Intrepid-class is highly advanced, the quarters in general are smaller than those of other vessel classes because of its smaller dimensions.

There are several types of crew quarters aboard:

Crew quarters on board an Intrepid-class starship Standard Crew Quarters These small quarters units are located within the primary hull and lack windows. They included a living area, a bedroom, and a bathroom. Crew members of Lieutenant Junior-Grade are given their own quarters; Ensigns and crewmen are required to share their quarters (except for senior officers). The living area contained a replicator terminal and is customizable with a variety of furniture and decorations.
Officer's quarters on board an Intrepid-class starship Officers' Quarters These quarters lined the edge of the saucer section and contained a living area, a bedroom, and a bathroom area. They are generally reserved for those of ranking lieutenant or higher. Members of the senior staff are typically assigned quarters featuring a pair of larger, wider windows.
The captain's bathroom Captain's quarters The captain's quarters, located on Deck 3, are similar to the officers' quarters but are slightly larger. The captain has a large desk area and work terminal. His or her quarters featured five windows (below the navigation lamp), which offered an excellent view of space in front of the vessel; the captain's quarters are positioned below the mess hall.

Transporter Systems

Intrepid-class transporter room

The Intrepid-class featured three transporter facilities that were located on Deck 4. In case of emergencies, injured personnel could be directly transported to sickbay from anywhere in transporter range, including inside the ship.

Like many Federation starships, the Intrepid-class' transporters had six standard pads located in front of a control console. Here the transporter controls were located in an elevated booth, and two officers could operate them in conjunction with a wall panel for more complicated transports. Like most systems aboard the Intrepid-class, the transporters utilized bio-neural gel packs in their processor systems.

Auxiliary Spacecraft Systems

Overview of the shuttlebay

Located in the aft dorsal portion of the secondary hull, the main shuttlebay was the primary port for entrance and egress, as well as management of auxiliary craft and shuttles.

Interior of the shuttlebay

Inward from the main shuttlebay was a secondary storage and maintenance area behind huge inner airlock doors. This secondary area was almost as large as the main shuttlebay and was commonly referred to as Shuttlebay 2.

The Intrepid-class starship was typically equipped with the following types of shuttlecraft:

The crew of the USS Voyager, stranded in the Delta Quadrant, constructed the Delta Flyer for more complex auxiliary spacecraft operations. The craft was in operation since early 2375. The Intrepid-class was also equipped with an aeroshuttle, which was visible on the underside.
