The Excelsior?s design drew upon the now traditional primary-secondary hull configuration first introduced in the Daedalus class of the late twenty-second century. The Excelsior?s space-frame consisted of five integrated main assemblies: the primary hull (saucer section), interconnecting dorsal ?neck,? secondary hull, warp nacelle pylon assembly, and twin warp nacelles (together comprising the engineering section). Each unit was constructed separately as an independent module at San Francisco Fleet Yards on Earth and then gamma-welded together with the others in drydock in synchronus Earth orbit. Overall vessel dimensions are as follows: Length, 467.05 meters; Beam, 177.21 meters; Height, 74.93 meters.
The primary hull, or more popularly the ?saucer section,? is considered to be the main hull component. It houses the main command facilities, including the main and auxiliary bridges and the main computer core, as well as main crew accommodations and crew support facilities including food preparation and laundry systems. It also contains the main dorsal and ventral sensor platforms, and the ten primary phaser banks. A spar extending aft along the longitudinal axis of the saucer section also houses the impulse reaction system and upper intermix chamber, which extends downward to the deflector alcove in the secondary hull. Overall saucer dimensions are as follows: Length, 198.51 meters; Beam, 177.21 meters; Height, 30.71 meters.
The interconnecting dorsal is one of the components of the ?engineering section.? Originally fitted with transwarp field monitoring and refinement equipment (its very chevron-shaped horizontal cross-setions defined by warp field dynamics), it is now primary void space, save the intermix chamber which spans it vertically. Auxiliary crew quarters and freight space can be found here, along with inertial damper systems.
The secondary hull itself is the main component of the engineering section. It is roughly cigar-shaped in design, with a flattened dorsal and perfectly curved ventral. It houses main engineering and primary warp power systems, including the antimatter storage systems, as well as the main deflector dish. Primarily a hollow unit, the secondary hull houses the massive combined Shuttlebay One/Main Cargo Storage Facility, Shuttlebay Two mounted at the fantail atop the dorsal, and the twin fore and aft torpedo launchers. Overall secondary hull dimensions are as follows: Length, 271.79 meters; Beam, 58.76 meters; Height, 43.93 meters.
The warp nacelle pylon assembly is composed of an elliptical hemisphere mounting the twin warp nacelle struts. The ?dome? unit houses the main plasma manifold and EPS system, as well as various engineering support systems. It is streamlined for greater warp performance. The massive twin warp nacelles are mounted securely atop the twin support pylons. They are roughly shaped like truncated squares in cross-section, and taper to their aft ends. Overall warp nacelle unit dimensions are as follows: Length, 247.08 meters, Beam, 17.70 meters; Height, 20.33 meters.
Deck One (A-Deck)
Deck one is a fairly large space extending across the very top of the primary hull spar aft towards the impulse engines. However, the only habitable volume of the deck consists of the main bridge/briefing room area at the front, which is sunken nearly two meters into a protective ring structure.
The bridge unit is an interchangeable module designed for swapout at regular refit intervals to facilitate easier control system upgrades. In keeping with Starfleet tradition, the bridge is a circular room lined with various instrument stations necessary for the operation of a modern starship.
The uninhabitable space of Deck One contains numerous systems. The protective ring around the bridge module contains auxiliary battery power and life support systems for emergency use. A bar extending aft from this unit contains the main high-gain subspace antenna, and is flanked on either side by the uppermost portions of the dorsal sensor platform within raised hull flats. Excelsior is equipped with an extensive suite of all modern forms of sensor modules.
Aft of this at the deck?s rear are the upper housing for the twin deflection crystals that top the intermix chamber and the upper impulse systems, including the radiative cooling unit baffles and fins. When she was originally launched, Excelsior mounted a single, large deflection crystal atop her intermix chamber. The deflection crystal allows warp power to be directly channeled to supplement the impulse system. However, flight tests proved that the large crystal tended to easily overload, so the ship?s 2287 refit and intermix chamber replacement saw the installation of a pair of smaller, more conventional deflection crystals capable of the same workload. These units have proven far more reliable and stable than the previous configuration.
Main Bridge
The bridge module originally equipped to the Excelsior at her commissioning in 2284 was quite different from the one installed in 2289 for her operational career, but the two still retain similar Starfleet characteristics. The 2284 bridge module was designed around the operation of the transwarp drive. It did not contain an observation lunge as on the new module, but was still an efficient control space. The room was a perfect circle, with a single turbolift directly aft and a large viewscreen forward, comprising nearly one-third of the room?s wall space, with small secondary exit doors to either side (leading to a surrounding corridor). The remaining wall space was dedicated to control consoles. A ?pedestal? in the center of the room mounted (for the first time) separate helm and navigation consoles, with Helm at starboard and navigation at port. The Captain?s chair was directly aft of these consoles.
The Captain?s chair, and indeed all the bridge chairs, was quite unusual and characteristic of Excelsior?s early career. They all mounted large inertial restraint arms that some crew nicknamed ?bear arms,? so described because in transwarp flight these mssive arms were programmed to literally automatically grab and securely hold the seat?s occupant. Also for the first time, Starfleet adopted the use of touch-screen ?Okudagram? control surfaces, so named after their inventor, Dr. Michael Okuda. These controls were far more sophisticated and versatile than their push-button predecessors, and could be reconfigured for specific needs far more easily. Okudagram interfaces quickly became the fleet-wide standard. ?Bear arm? chairs, however, heralded the end of physical seating restraints in favor of interwoven gravity cushions and better intertial damper systems.
The Excelsior?s 2287 refit and transwarp drive removal prompted the replacement of the 2284 bridge module, and Starfleet took the opportunity to equip her with something even more modern and cutting-edge. The 2289 module retained the circular dome-shape for the bridge with Okudagram touch-screens, but is distinctly different from its predecessor. Two turbolift stations serve this bridge, one each at port and starboard. The viewscreen remains virtually unchaned, but is slightly smaller, and gone are the forward corridor access doors.
Stations lining the bridge walls include: engineering support, propulsion, communications, and tactical monitoring at port; three dedicated science statsions and a small master control monitoring station at starboard. The upgraded Captain?s chair, and helm and nav consoles retain nearly the same locations on a platform level with the circumferential stations, but the helm and nav are flipped, returning to their familiar positions. A small table has been provided in front of the Captain?s chair for his convenience. An alcove at the aft of the bridge houses the new master situation display, a graphic of the ship that allows the Captain to view the ship?s status at a glance over his shoulder. Doors flank the MSD, which allow access to the new briefing room/observation lounge, and an adjacent head for the bridge crew?s use.
Briefing Room/Observation Lounge
The new observation lunge provides an unparalleled view of the aft portion of the ship and the warp nacelles, and was designed to allow the senior staff a more convenient location for mission briefings. It features a long, slightly curved table fitted with computer access systems and chairs for each member of the senior staff. Each end wall is fitted with a fairly sizeable viewscreen and data interface for briefing sessions. The inner wall is decorated with art and other personal decorations provided by the Captain. The Captain may also use the room as a ready room if so desired to relax when key situations require his proximity to the bridge.
Deck Two (B Deck)
Deck two is an almost fully habitable deck that forms the uppermost part of the primary hull dorsal spar. It features the centrally located top of the main computer data transfer trunk, where it mates with the bottom of the bridge module. The trunk spans the space from the main processors on deck seven up to the bottom of the bridge module at the top of deck two, facilitating rapid data transfer to key command areas in the saucer. Additional data transfer conduits branch from the central trunk like branches of a tree, eventually stepping down to transfer conduits mere millimeters in diameter where they meet control interfaces. The ship?s fourteen science labs are located on this deck,adjoining the computer core trunk, where they are directly fed data by the dorsal sensor platform above. In addition, quarters for VIPS such as diplomats and admirals are found on this level. In a small uninhabitable section at the front of this deck are additional sensor modules for the dorsal sensor platform, with related systems.
Aft, the main stairwell top is found. The stairwell provides easy access to the ship?s main decks in the event of an emergency. Further aft is the lower deflection crystal housing, with a dedicated monitoring room. The crystals shed brilliant patterns of light across the room?s bulkheads as they surge with raw power, just atop the warp intermix chamber. Aft of this is the upper part of the multi-level impulse reaction system, including the upper parts of the fusion reactors and coolings systems, and the twin driver coil assemblies and exhaust units.
VIP Quarters
Impulse Reaction Systems
Deck Three (C Deck)
Deck three is also almost fully habitable, and contains the senior officers? quarters, including the Captain?s cabin. The computer core data trunk again forms the center of this deck, with a circular monitoring room around it. The habitable portion of the deck is lines with the five dorsal phaser banks and control rooms and emergency lifeboats concealed behind the outer hull in blow-away panels. Life support and other supplementary systems fill the uninhabitable space beyond.
The aft section of this deck features the continuing main stairwell and the top component of the intermix chamber, surrounded by a circular observation room. Aft of this are the lower components of the impulse reaction systems.
Captain?s Quarters
Senior Officers? Quarters
Phaser Banks
Lifeboats
The lifeboats equipped to the Excelsior were the most advanced such vehicles yet introduced. Their primary purpose is the emergency evacuation of the ship in the event no other escape or evacuation options are available, and the preservation of the ship?s crew long enough for help to arrive. Previous models have proven instrumental in saving crews of dying starships time and again. Early one-man models were equipped to the earliest Federation starships, and instantly proved their worth.
Excelsior?s lifeboat model is roughly cubical, with truncated corners. Each vehicle is capable of supporting four people for a maximum of two weeks, depending upon battery power usage. A small, squared hatch provides access to the craft?s interior. A small-scale escape impulse engine provides for a fast escape from the ship in the event of a disaster, with maneuvering power provided by an RCS thruster at each corner of the lifeboat. A small deuterium tank provides fuel for the microfusion reactor and thrusters in each unit. A transponder beacon automatically activates upon launch, but may be deactivated by lifeboat occupants should conditions warrant. Emergency braking parachutes are stored within outer hull compartments for planetfall situations. Emergency rations and other survival gear are stowerd behind access panels in the lifeboat?s walls.
In the event of an emergency evacuation, the crew may access lifeboat loading rooms through doors in the ship?s outer corridors. The crew may trigger an auto-deployment sequence, or a crewman may wish to initiate manual deployment operations. In either case, small explosive charges will blow away the exterior hull panels that conceal the clusters of lifeboats and allow them to leave. A quarter-impulse escape burst should allow the lifeboats to escape the ship in most disaster scenarios. The pod may subsequently land on a planet, or wait to be picked up by a Federation starship.
Deck Four (D Deck)
Deck four is comprised almost totally of crew accommodations, including junior officers? quarters and general crew bunks. The computer core data trunk and monitoring room is again a central feature. Additional lifeboats are found at the deck?s perimeter, with further support systems in the small uninhabitable spaces beyond.
The aft end of the deck finds the next level of the main stairwell in addition to another intermix chamber observation room. Aft of this are the main deuterium storage tank tops (which in total span four decks) and pumps. These units fed the impulse reactors directly, and have been designed to also supplement the warp deuterium unit in the secondary hull as needed. However, it has become a more common practice to simply allow the main tanks to directly feed the intermix chamber, rather than going to the additional effort of pumping the fuel to the deck 15-16 tank first. This small tank has become more of a supplementary supply in the event of an emergency. Impulse regulation subsystems and auxiliary inertial dampers fill the remainder of space on this deck.
Crew Quarters
Deck Five (E Deck)
Deck five houses some of Excelsior?s most vital facilities. The auxiliary bridge lies at the heart of the deck, surrounding the computer data trunk. This facility is perhaps the most well-protected in the ship, and is designed to beoome an emergency combat command center in the event a devastating attack renders the main bridge useless or destroyed. This facility is protected by the utmost security, accessible only at the proper authorization of a senior officer.
Almost encircling the auxiliary bridge at the fore side is the medical section. This facility is among the most critical to the vessel as it ensures the well-being of the ship?s most vital component, its crew. Further junior officers? quarters and extensive crew quarters are also found on this deck.
The aft end of the deck finds the continued main stairwell and another intermix chamber observation room, followed by the second level of the main deuterium tankage. Support systems fill the space around and between the deuterium tanks.
Auxiliary Bridge
Medical Section
Deck Six (F Deck)
The central component of deck six is the lowest level of the main computer core data trunk surrounded by various sub-processing systems that sit atop the very main processor systems themselves found on the decks below. Most of the deck is made up of crew accommodations, including the lowest junior officers? quarters and crew quarters. This deck also features the main recreation facilities, including the rec room itself (featuring a number of entertaining games) and the ship?s gym and phaser ranges. The four main transporter rooms are found on the port and starboard sides of the deck, with armories adjoining them. Twin cargo transporter rooms are also found nearby. These may be used to beam up perishables and crew freight while in dock, or to save precious cargoes from the main bay before saucer separation. The quartermaster?s office is also nearby. The quartermaster is responsible for providing equipment and provisions to all hands, and monitors the ship?s inventory.
The deck?s aft section finds a number of support systems essential in event of saucer separation, including life support and the pumps for the reclamation systems, which are found one deck below. Further aft the main stairwell continues, and another intermix chamber observation room is also found. The third level of the main deuterium tankage is found further aft, with more support systems surrounding it.

Deck Seven (G Deck)
Deck seven is the higher of the so-called ?service decks,? the bottom two habitable decks of the saucer section. The upper level of the main computer processors forms the heart of the deck. The ship?s galley and food preparation systems are nearby, with the ship?s pantry and cargo and freight facilities adjoining. These facilities serve as the storerooms for the ship?s perishables and those cargoes vital to the crew. They are located here so they will still be available in the event of an emergency saucer separation. The officers? and crews? messes are also located nearby.
The ship?s auxiliary deflector array is also concealed at the front of the deck, intended for use in the vent the main deflector in the secondary hull fails or is severely damaged. Extensive crew quarters are also found on this deck. Transporter buffers are also found to the port and starboard of the computer processors, directly below their respective transporter rooms.
The ship?s laundry and solid and liquid waste reclamation systems are found just aft of the computer processors. These facilities allow the recycling and re-use of damaged or dirty clothing and equipment and of the crew?s waste. The machinery here can almost instantly turn a torn, burnt tunic into a new uniform, or a pair of worn-out boots can be made new again. Reusable components of biomatter waste are also extracted here before the remaining flotsam is jettisoned into space. The umbilicat-disconnect points for the secondary hull are also found nearby. These ports normally allow the flow of resources and waste between the ship?s two sections, but are sealed in the event of an emergency separation procedure.
Further aft is the lowest level of the main stairwell found in the saucer, where it can be sealed in event of separation, and another circular intermix chamber observation room. This room houses the emergency valve designed to sever the intermix chamber in the event of a separation. However, it is procedure to try to eject the core first if there is a problem than to separate the ship; a new core can be installed far more easily than a secondary hull constructed or reintegrated.
Aftward is the fourth and bottom level of the deuterium tankage, the lower pumps, and the disconnect valves that sever the lines that run between the main tanks and the warp deuterium tank in the secondary hull. Additional support systems fill the limited remainder of space on the deck.
Ship?s Computers
Galley and Food Preparation Systems
Ship?s Laundry and Waste Recovery Systems
Deck Eight (H Deck)
Deck eight is comprised of the lowest habitable portion of the saucer section, and the first level of the interconnecting dorsal ?neck.? While approximately 40% of the portion of the deck beneath the saucer does not achieve full height, this deck contains vital systems nonetheless. The lower level of the main computer core processors are found at the heart of the deck, where they mate directly with the navigation dome on the deck below. More saucer freight and cargo holds surround them. The perimeter of the habitable space on the deck is lined with the five ventral tandem phaser banks and control rooms, and the ventral lifeboats. Beyond is the uninhabitable section. This area contains the ship?s main freshwater tanks and adjoining pumps and machinery, along with the other raw materials storage tanks, and the four massive landing struts intended for use in an emergency planetfall operation. Beyond this the outer ventral sensor platform forms and almost complete recessed ring around the saucer?s hull. Additional space on the deck further out houses further support and supply equipment.
The portion of the deck within the interconnecting dorsal neck houses separation systems, including the receptacles for the saucer umbilical disconnects and the explosive separation bolts and related systems. In an emergency, these bolts destroy the connectors between the primary and secondary hulls and render them two separate vehicles. The main stairwell also continues on this deck, and another intermix chamber observation room is found slightly aft, where the lower portion of the emergency separation valve can be seen.
Emergency Separation and Planetfall Operations
Deck Nine (I Deck)
Deck nine is the first level of the saucer ventral that is completely uninhabitable. This section contains the ventral sensor platform and the subsystems for the navigation dome mounted beneath, as well as the upper portion of the navigation dome itself. The ship?s helm personnel use this dome as a dedicated sensor to chart and reference astrological phenomena while in flight as navigation references.
The interconnecting dorsal neck portion of this deck is fully habitable. It contains some emergency quarters typically used by the engineering crew in a period of high alert while proximity to engineering is necessary. These quarters are also capable of being reconfigured to accommodate species that require any number of exotic atmospheres. The main stairwell continues on this deck, and another intermix chamber observation room is found near its center. Some engineering support systems are found on this deck as well, including main inertial damper subsystems, but much of the deck remains empty for future hardware expansion?a result of the vast amount of transwarp-related equipment stripped from the ship in her 2287 refit.
This deck is also the topmost level of the warp support pylon dome mounted several dozen meters back on the secondary hull dorsal. While uninhabitable, this deck houses further inertial damping systems and EPS (electro-plasma system) relay subsystems.
Deck Ten (J Deck)
While not technically a deck, and certainly not habitable, the portion of deck ten found on the saucer ventral mounts the exterior portion of the navigation dome system.
The habitable portion of deck ten found in the interconnecting dorsal neck is again dominated by an intermix chamber observation room and the continuing main stairwell. Inertial dampers are also found on this deck. The deck also features the top portion of the phaser cannons mounted on the deck exterior. These weapons are comparable to those found aboard Miranda-class vessels, and are intended for use against starbases or other stationary targets. More emergency quarters and life support systems are also on this deck.
This deck also features the top habitable level of the support pylon dome. The upper components of the EPS power taps are found here, along with numerous related subsystems and further inertial dampers.
Deck ten also corresponds with the top of the Shuttlebay Two aft canopy. The streamlined canopy top houses the two aft tandem phaser banks and pressurization and actuation machinery for the shuttlebay doors.
Deck Eleven (K Deck)
Deck eleven is the first deck not including a portion of the saucer section. The interconnecting dorsal neck houses the continuing main stairwell and another intermix chamber observation room, in addition to more inertial dampers. A few scattered emergency quarters and engineering support systems surround these features.
The main portion of the EPS plasma manifold are found in the support dome on this deck, in addition to the support pylon power transfer conduits and connect points themselves.
The observation lunge, bay control and observation deck, and high bay are found aft in the Shuttlebay Two facility on this deck. The observation lounge allows flight and shuttle maintenance crew a place to relax while on duty, and provides a staging area for departing away teams. It also features an unparalleled view of the warp nacelles and forward part of the ship.
Deck Twelve (L Deck)
Deck twelve is the bottom level of the interconnecting dorsal neck. It features the lowest main level of the main stairwell where it meets a Jeffries tube to main engineering on the deck below. The intermix chamber is surrounded by an observation room which provides direct access to the engine room below. Parts storage bays and support systems fill the remainder of this portion of the deck.
Deck twelve is also the lowest level of the support pylon dome. The lower components of the EPS plasma manifold are found here, along with related subsystems. This is also the point where the power transfer conduit from the intermix chamber meets the EPS manifold.
Deck twelve aft is the location of the Shuttlebay Two landing deck. It joins a small cargo hold slightly forward in the complex which is equipped with a small cargo transporter. The landing deck floor is equipped with landing systems and an elevator to provide shuttle access to the maintenance hangar and machine shops below. Landing bay door retracting machinery is also found within the deck twelve floor.
Shuttlebay Two Complex
Type-4 Shuttlecraft
The Type-4 shuttlecraft is one of two auxiliary vehicles developed as a side project of the Excelsior Development Project, benefiting from the numerous technical advancements that came out of out the project. The Type-4 shuttle, as indicated by its designation, is the fourth-warp capable shuttlecraft design developed by Starfleet, the first having been completed and tested in the late 2260s. Until that time, most shuttles, such as the S-Class popularized during the 2240s-2260s, had been limited to sublight speeds due to warp drive system size concerns. The smallest true warp-capable ships of that era were light scouts, and finally Class-F shuttles were developed as warp-capable variants of the S-Class sublight shuttle, but saw little use outside of starbases. By 2284, the Type-4 was delievered as a true successor to the venerable S-Class series. The Type-4 is truly a mult-purpose support craft, capable of scouting, cargo ferrying, and troop insertion operations.
In design, the Type-4 resembles a streamlined version of the S-Class, with warp nacelles replacing impulse booster rockets. RCS microthrusters mounted at key points on the hull provide maneuvering power. An enclosed deflector array is mounted beneath the nose. Two horizontally split forward doors allow direct personnel access to the two-seat cockpit. Control instrumentation is standard and relatively simple to understand. A large forward window provides a substantial forward view. An under-console bin provides storage for personnel equipment such as phasers and communicators. An aft section provides a staging area and bench seating for personnel, and generous floor space for cargo stowage. Equipment recharge ports are incorporated into the bulkheads. Impulse engines have been slung to the side to allow the inclusion of a large aft cargo door that doubles as a loading ramp when opened. A single microphaser bank mounted atop the dorsal hull between the forward doors provides defense. A graviton thrust array mounted on the ventral hull surface provides loft. Overall dimensions are as follows: Length 9.1 meters; Beam, ; Height, .
Two ejectable fuel tanks, mounted on either side of the aft hull beneath the impulse engines, supply fuel to the micro-warp reactor housed beneath the aft deck for the matter/antimatter reaction. The small warp reactor (which may also be ejected in an emergency) in turn provides power to the small warp nacelles. The Type-4 is rated at achieving a maximum warp velocity warp 1.5, can achieve full impulse, and in atmospheric flight is rated for Mach 2.0.
While initially deployed only to Excelsior, the Type-$ has since gained use throughout the fleet, and has proven its success already, ensuring a long and healthy career as a mainstay of the Federation shuttle fleet for decades to come.
T-Class Travel Pod
The T-Class Travel pod is an older utility vehicle first introduced in the early 2260s that can trace its design lineage back to the earliest shuttlepod vehicles developed by Starfleet. Capable only of low sublight velocity and short trips, it is by no means an independent vehicle. Originally designed for use as a dockside utility and inspection vehicle only, variants of the travel pod design have since gained use throughout the fleet as short-range courier vessels. Their integral docking rings and generous interior space make them ideal for ship-to-ship or ship-to-base transfers of cargo and personnel when transporters are undesirable or occupied. While not commonly used for planet landings, they are capable of atmospheric flight and touchdown.
The standard T-Class pod is a fairly small, single-component assembly featuring no exterior nacelles or engine cowlings. Propulsion is provided solely by enhanced RCS thruster units mounted strategically across the hull. A large window and floodlights make the vehicle an excellent inspection craft. Main interior access is provided by the docking ring doors, but in an emergency dorsal and ventral escape hatches also provide egress. The interior of the pod is spartan but quite spacious. A typical pod is not even equipped with eating, although it may be installed quickly if so desired. Comfortable accommodation can be made for six people at a time. Life support and supplies are limited, as the pod is intended only for short-range trips between Federation vessels and stations. A small microfusion reactor located beneath the deck plating provides main power, with limited emergency battery supplements. Some T-class variants mount conventional articulared doors instead of a docking ring, and even impulse engines, but these are quite uncommon. Overall dimensions are as follows; Lengh, ; Height, ; Beam, .
The sheer necessity for a rugged, simply utility vehicle ensures the livelihood of this small vessel in docks and space stations throughout the Federation well into the twenty-fourth century.
Work Bee
Deck Thirteen (M Deck)
Deck thirteen is the uppermost level of the main secondary hull section. Main engineering is located here (a fact not lost on the ship?s unlucky original transwarp engineers.) The forward tractor beam is located at the deck?s very front. Lateral sensor arrays line the entire deck?s perimeter. The warp power transfer conduit runs nearly half of the deck?s length back to the support pylon dome.
Aft of this is the high bay for the main cargo storage facility, located just beneath the secondary hull strongback. Auxiliary barracks-style crew quarters and science labs line the perimeter of the cargo facility.
Additional auxiliary crew quarters are located aft of the cargo facility high bay for emergency situations, particularly saucer separation, but may be used by the Cargo Bay and Shuttlebay Two flight crew in periods of extreme workloads. The transporter buffer for the Shuttlebay Two cargo transporter can be found just aft. Further aft of this are machine ships and parts bays for Shuttlebay Two, and indeed the Shuttlebay Two maintenance hangar itself. Elevator machinery is mounted in the deck floor to receive the elevator from the landing deck above. At the very aft end of the deck is the rear tractor beam unit that serves the shuttlebay.
