MAIN BRIDGE

 

General Overview: Primary operational control of the Excelsior Class is provided by the Main Bridge, located at the top of the primary hull. It is located on Deck 1. The Main Bridge directly supervises all primary mission operations (with the exception of the Flight bay and assorted craft) and coordinates all departmental activities.

The Main Bridge is a highly restricted area; only Beta-Two security clearance personnel (Officers with the Rank of Ensign or Higher) and authorised bridge personnel are allowed on the bridge. All bridge officers have access to a small armoury on the bridge that carries type II phasers.

The Main Bridge is an ejectable module, allowing for a wider variety in mission parameters.

Layout: The central area of the Main Bridge provides seating and information displays for the Captain and two other officers. The Captain’s Chair is raised from the rest of the Bridge Officers, to that of the surrounding level which includes Tactical and Operations. The two Officer seats are equipped with fully programmable consoles for a variety of uses.

Directly fore and to the right of the command area is the Flight Control Officer, who faces the main viewer. The FCO is equipped with a console that proceeds around at a 45 degree angle.

 

Directly fore and to the Captain's left is the Operations manager's console. Identical in size and design to the Helm station, the Operations console is one of the most sensitive consoles to access on the bridge, due to the wide variety of information available there.

At the very front of the bridge chamber is a large viewscreen. This main viewer performs all the standard duties expected of it. However, the viewscreen is not always activated like most other Starships. It is a full Holographic display, that can be activated upon request. When the screen is not active, the screen remains dark.

 

Aft and to starboard of the command area is an elevated platform on which is located the tactical/security control station (comprised of two consoles, one for tactical, and one for security, located directly behind tactical and along the back of the bridge area). These consoles are to the starboard side of the Captain’s Chair, no longer in the direct middle.

Against the port side walls of the main bridge are the consoles for Science and others that are programmable for a multitude of functions. There are two Science consoles with Science 2 being a fully programmable multi-mission Console. Science I, which is the primary science console. Science I has priority links to Conn, Ops, Computers, and Tactical.

 

Science II is the ASO's (Assistant Science Officer's) console, which can be used by any personnel. Science II has access to all science, navigational, sensor, and communications systems. Science II can be configured to operate in tandem with Science I, although security links and all other non-science data is withheld from Science II. Science II usually works independently of Science I.

 

Against the aft wall of the main bridge is the large engineering console. This has a smaller cutaway diagram of the starship, which displays all engineering-relevant data and shows warp fields and engine output. This console also has priority links to the computers, the WPS (Warp Propulsion System), the IPS (Impulse Propulsion System), navigation, SIF, and IDF. Although usually unattended, the Chief Engineer can bring this console to full Enable mode by entering voice codes and undergoing a retinal scan. Also located on the platform, against the aft wall of the bridge, is a large master systems display monitor, similar to the one in main engineering.

 

All relative ship information (such as damage, power distribution, etc.) is displayed on the cutaway image of the starship. This monitor can be used to direct ship operations and can be configured for limited flight control if necessary. Also located in the Bridge Engineering is the Engineering II console, which is fully programmable to run any Secondary Console function, including Sciences, Medical, Operations, Limited Helm control, or Security.

 

This console, as does every console on the bridge, also has the hand-input sub-console for use in setting the auto-Destruct of starship. The auto-destruct sequence follows Standard Starfleet security procedures which can be accessed via any secured Memory Alpha ODN connection.

There are two turbolifts on the bridge that can handle normal transit around the starship. There is also an emergency ladder that connects the bridge to Deck three. There is also one door, on the aft platform of the bridge, that leads to the Conference Room, which is directly aft of the Main Bridge. Other connected rooms to the Main Bridge include the Captain's Ready Room.

 

There are no escape pods connected to the bridge. Pods are located on all decks below Deck three. Each pod can support two people for 4 hours in space, and has a maximum speed of half impulse. Two pods are reserved for the top four officers in the chain of command on the starship, because they are the last four to leave the ship. These are located on Deck two. As the number of experienced Captains dwindles in Starfleet, the notion of a Captain going down with his ship has been abolished. If the ship is abandoned, the top four officers in the chain of command will wait until everyone else is off the ship, opt to arm the auto-Destruct (not always necessary, but there if needed), and then leave in the two escape pods.

MAIN ENGINEERING

 

Located on Deck 12, Main Engineering is the ‘heart’ of the ship, comparable to the bridge as ‘brain’. It has access to almost all systems aboard the starship, and manages repairs, power flow, and general maintenance.

 

Entrance to Main Engineering is provided by two large blast doors that can be closed for internal or external security reasons. Just inside of that is an observation area where technicians monitor various systems of the ship. Also in that area, is a floor-mounted situational display similar to the Master Systems Display found on the Bridge. Affectionately referred to as the 'pool table' the Chief Engineer can use the display to more easily get a broad view of the situation with just a glance.

 

Farther in from the observation area is the warp core and main control systems. Circular in shape, the room was designed to be small but exceedingly functional to save space inside the ship. Usable consoles are mounted on every piece of ‘real estate’ around the circumference of the room and provide primary control access for the engineers and technicians.

 

Off to the starboard side of Main Engineering is the Chief Engineer’s Office, which is equipped with a diagnostics table, assembly and repair equipment, a small replicator, and a personal use console with built-in private viewscreen.

In the centre of Main Engineering is the Matter/Anti-Matter Assembly (M/ARA). This is where primary power for the ship is generated inside the Matter/Anti-Matter Reaction Chamber (M/ARC). This system is checked on a regular basis due to its importance to the ship. Access to the warp core is restricted, with a front port to get to the Dilithium matrix as well as an over side port for access to the warp plasma conduits.

 

A second tier rings the second level of Main Engineering. A small single-person elevator, as well as a ladder on the opposite end, provides access to this catwalk.

Access to the Jefferies Tubes is provided in various places on both the First and Second Tier of Main Engineering.

 

Typical crew compliment in Main Engineering consists of twenty engineers and thirty technicians of various grades. During Red or Yellow Alert, that number is increased.

 

CREW QUARTERS

 

General Overview: All crew and officers' (except for the Commanding officer's and Executive Officer's, which are located on deck 2) crew quarters are located on decks 3, 4, 8, 13-15 and 22-24.

 

Individuals assigned to the Excelsior Class starships for periods over six months are permitted to reconfigure their quarters within hardware, volume, and mass limits. Individuals assigned for shorter periods are generally restricted to standard quarters configuration.

 

Crew Quarters: Standard Living Quarters are provided for both Starfleet Non-Commissioned Officers and Ensigns These persons are expected to share their room with another crew mate due to space restrictions aboard the starship After six months, crew members are permitted to bring family aboard the ship and a slightly larger room is allocated to them.

 

Two NCO's or two Ensigns are assigned to a suite. Accommodations include 2 bedrooms with standard beds, connected by a living/work area. A washroom with ultrasonic shower is located off of each bedroom. A food replicator and a personal holographic viewer are located in the living area. Small pets are allowed to NCO's.

 

Enlisted crew members share quarters with up to 4 others. Accommodations include 2 bedrooms with twin beds, connected by a living/work area. A washroom with ultrasonic shower is located off of each bedroom. A food replicator and a personal holographic viewer are located in the living area. Pets are not allowed to enlisted crew.

 

Crewmen can request that their living quarters be combined to create a single larger dwelling.

Officers' Quarters: Starfleet personnel from the rank of Lieutenant Junior Grade up to Commander are given one set of quarters to themselves. In addition, department heads and their assistants are granted such privileges as well, in an effort to provide a private environment to perform off-duty work. After six months, officers are permitted to bring family aboard the ship and a slightly larger room is allocated to them. Members of the Captain's Senior Staff can have these restrictions waved with the Captain's permission.

These accommodations typically include a small bathroom, a bedroom (with standard bed), a living/work area, a food replicator, an ultrasonic shower, personal holographic viewer, and provisions for pets.

 

Officers may request that their living quarters be combined to form one large dwelling.

Executive Quarters: The Captain and Executive Officer of the Excelsior Class starship both have special quarters, located on Deck 2. They are located on a higher deck because these two people must be closer to the bridge in the event of an Alert situation.

These quarters are much more luxurious than any others on the ship, with the exception of the VIP/Diplomatic Guest quarters. Both the Executive Officer's and the Captain's quarters are larger than standard Officers Quarters, and this space generally has the following accommodations: a bedroom (with a nice, fluffy bed), living/work area, bathroom, food replicator, ultrasonic shower, old-fashioned water shower, personal holographic viewer, provisions for pets, and even a null-grav sleeping chamber.

 

VIP/Diplomatic Guest Quarters: The Excelsior Class is a symbol of UFP authority, a tool in dealing with other races. Starfleet intends to use most of its starships in a diplomatic role, with the Excelsior Class being no exception. The need to transport or accommodate Very Important Persons, diplomats, or ambassadors may arise, to which the Excelsior Class may respond.

These quarters are located on Deck 3. These quarters include a bedroom, spacious living/work area, personal viewscreen, ultrasonic shower, bathtub/water shower, provisions for pets, food replicator, and a null-grav sleeping chamber. These quarters can be immediately converted to class H, K, L, N, and N2 environments.

 

AUXILIARY SPACE CRAFT

 

Flight (Shuttle) bay: General Overview: Located at the dorsal bow of the ship, the Flight bay module has replaced the shuttlebay module that is in previous Classes Starships. This Flight bay contains the latest in Starfleet shuttle and runabout designs. The Flight bay is controlled by a space/air-traffic control room, known as "Flight Ops". This is located against the forward wall of the Flight bay, next to the exit for the turbolift. The Flight bay contains the following:

Eight Type III shuttle craft

Seven warp sleds

Six fighter craft

Four work bees

TYPE III SHUTTLE HISTORY

The original requirement called for the Type 2 to be fully warp capable, as was its predecessor, but here the project ran into difficulties. The new Miranda / Constitution designs had introduced, among many other things, a completely new nacelle design. This had suffered from considerable difficulties when introduced; getting the engines into the proper balance tended to be very difficult, requiring prolonged computer modelling and simulation for each individual vessel. Use of the engines when not properly balanced tended to generate wormhole-like phenomena, as encountered by the USS Enterprise on her first warp flight after completing her refit in 2271.

 

Although these difficulties where eventually solved for the larger ships, the miniaturizing of the nacelle design for use on board the Type 2 compounded the problem. The first three Type 2 shuttle prototypes produced where all lost to wormhole effects; fortunately all three where flown unmanned and no loss of life was incurred. Great efforts where made to try and correct this difficulty, but by 2274 the design was still unworkable and Starfleet dropped the entire project.

However, the need for a shuttlecraft still existed and so by 2276 the Type 2 had been reborn as the Type 3. Starfleet decided that the miniaturization of the warp drive was a lost cause, and modified the design so as to limit the shuttle to impulse flight only. After this development proceeded remarkably smoothly, but Starfleets understandable caution led to a rather prolonged testing programme; the first prototype was successsfully flown in 2278, and the first production test model was delivered late in 2279. Series production began in 2280, with the first units arriving at their starships in June of that year.

After a successful first year in service, Starfleet stepped up production of the Type 3 and began to deliver them fleetwide in large numbers. The type quickly became a very common sight in Starship shuttle bays. The Challenger shuttlecraft are named for the seven astronauts who perished in the space shutle Challenger explosion and mission commander on Earth in the 20th century.

WARP SLED HISTORY

 

Although supply and support vessels have never had the glamour of the big Explorers, their role is at least as important to the day-to-day functioning of an organization like Starfleet as any other class. The Vulcan Warp Sled is a classic example of this; these handy little ships where in Starfleet service for over a century, in numbers which at their peak rivalled any other single class in service. Although they received little fanfare during their time, the warp sleds importance to starfleet can hardly be overstated.

 

The Warp Sled was one of the first shuttlecraft-sized vessels with a true interstellar capability. Although several previous shuttles did have warp capability, these where generally confined to specific routes between neighbouring systems - they tended to be either too slow or two short ranged for general use. The Warp Sled was capable of holding Warp 6 for up to two months on internal fuel alone, and was unique among shuttle craft in that it could conduct in-flight refuelling from standard tanker craft. This allowed it to operate almost indefinitely - on one occasion a warp sled made a flight lasting one hundred and fifty six days.

Another major advantage of the warp sled over previous designs was its flexibility; the sled itself consisted of a pair of warp nacelles, matter/antimatter reactor assembly and fuel supply mounted onto a large docking platform. A wide variety of pods was developed for attachment to this platform - the most common was a twelve person shuttle pod which was intended for relatively short duration flights. A six person unit with small bunk spaces was also available, as well as a single occupant VIP unit. Other variants included a cargo pod, a sensor pod which allowed the sled to be used as a long range remote controlled sensor probe, a medical evac unit with space for four patients and an attendant and a search and rescue pod designed to locate and retrieve ships lifeboats.

WORKBEE HISTORY

 

One of the most useful and long lasting designs in Starfleet history, the work bee was first fielded in the late 2260's in order to replace several previous craft of similar type. A major feature of the work bee is the highly modular nature of the design. A central cockpit module has space for a single operator. This cockpit can be connected to a variety of sleds or other attachments. The bee does not have an artificial gravity system, with many crewmembers reporting that they prefer this zero gee working environment. The cockpit module can be used with the door removed, the operator wearing a pressure suit. The modularity made the initial work bee design somewhat more complex and difficult to produce, but Starfleet was betting that it would prove its worth in the long run - and so it has proved. The work bee is simplicity itself to maintain; minor parts can be swapped out literally in seconds, while major systems such as the micro-fusion power core can be replaced in under ten minutes, and even the hull itself can be broken up into four sections. This has given these bees one of the highest servicability ratings in Starfleet history, with an average availability of 99.97%.

 

The modular approach has also made the work bee extremely easy to upgrade - all updated systems have been designed to fit the same physical requirements, so it is literally a matter of pulling an old component out and putting the improved one in place. No component swap requires more than three persons, and typically the total maintanence work required by the bees is so low that a three person crew can perform all routine maintanence on a group of fifteen bees.

The upgrade program for the work bees has been generally limited to gradual imporvements rather than large leaps. Over their hundred year history virtually every part of the bees have been replaced many times over. The original design had a duotronic flight computer, an electro-optical passive scanner, and a hull constructed of carbon fibre plated with foamed aluminium alloys - a very old material which nevertheless met the strength and and density requirements. The life support systems have been replaced several times as older systems reach the end of their operational life, or as newer safety standards come into force. Some have compared this rolling refit program to the proverbial thirty year old axe which has had four new heads and six new handles!

The work bee can carry out a multitude of tasks; there are two manipulator waldoes which can be tipped with a wide variety of tools for all kinds of construction and maintanence work on Starships and space stations. At the rear of the hull are standardized grapple points which can be used to attach various configurations of cargo containers, or alternately can be fitted with a tractor beam unit which can be used to tow small craft such as shuttles - a task the work bee would normally undertake only in emergencies. Some thought was given to designing drop tanks with extra fuel and life support supplies to extend the range of the bee severalfold, but although this was perfectly feasible there was never any real need for such an improvement and it was abandoned before serious development work was authorized.

EXCELSIOR CLASS HISTORY

 

The history of the Excelsior class tends to consist of extremes. Initially fitted with a Transwarp drive and proclaimed "the great experiment", the ship had an ignoble start when its engines failed when it was called into action to prevent the theft of the USS Enterprise. Although this was due to deliberate sabotage, it transpired that the Excelsior had been saved from a major disaster; engineers working to correct the damage discovered a series of flaws in the Transwarp drive which, had it been used, would have caused a nacelle implosion which would have destroyed the ship. The Excelsior spent nearly a full year in Spacedock while engineering specialists struggled to repair the problem. Re-launched early in 2286, the ship met with little more success. Although the fatal flaw of the Transwarp drive was repaired, the system was subject to major problems and over the next year it never completed a successful test, much to the embarrassment of Captain Styles and his crew. Finally Starfleet canceled the Transwarp project altogether, and for a short time the Excelsior faced decommissioning.

 

There was nothing wrong with the basic engineering of the space frame however, and in all other areas the Excelsior class was still the most advanced ship in Starfleet, and indeed the entire Quadrant, by a considerable margin. In light of this Starfleet rapidly decided to fit the Excelsior class with a more conventional propulsion system. She returned to Spacedock for the third time in 2287 to have her hull converted to run with a standard Warp drive. This process went remarkably smoothly, and by the end of the year the Excelsior was in space again. From here the history of the ship leapt from one extreme to the other; from being a costly and embarrassing failure, the Excelsior rapidly built a reputation for outstanding performance and a solid reliability few other designs have matched. The Excelsior herself was assigned to Captain Sulu in 2290 and conducted extensive scientific, exploratory and diplomatic missions under his distinguished command. Today the ships of the Excelsior class continue in service, having undergone many refits and upgrades.

 

REFIT HISTORY

The first major subgroup of the Excelsior class, the Enterprise-B subtype was designed for greater burst speed and maneuverability than the standard Excelsior and carried a much more elaborate electronics fit. The intention was to counter the new generation of cloak capable vessels being deployed by the Klingon empire; Starfleet was especially worried about developments which might permit Klingon vessels to fire whilst still cloaked, and it was these in particular that the new type was designed to counter. Wake homing torpedoes were fitted as standard, while plasma detector systems allowed the new ship to locate almost any existing vessel through its cloak. The advanced sensors of the Enterprise-B were also able to engage vessels firing from cloak by automatically locking phasers onto the origin of the weapons fire and almost instantly laying down a pattern of fire on the immediate area before the enemy vessel could change its position.
