USS Tomcat Engineering Department

Main Engineering is the “heart” of the ship, comparable to the bridge as the “brain”. It has access to almost all systems aboard the starship, and manages repairs, power flow, and general maintenance. Entrance to the primary engineering spaces is provided by two large blast doors, a pair each on Decks 14, 15, and 16 that can be closed in cased for internal or external security reasons, as well as in case of emergencies.  Deck 14 is known as Upper Engineering. Deck 15 is known as Main Engineering.  Deck 16 is known as Lower Engineering.


Just inside of the doors to Main Engineering is an observation area where technicians monitor all the various systems of the ship.  Also in that area, is a floor-mounted situational display similar to the Master Systems Display found on the Main 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 observation area is the warp core and main control systems. Circular in shape, the room is an outgrowth of the Galaxy Class design, 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. Additionally, there are numerous ladders and access panels to Jefferies tubes, leading throughout the starship - the Sovereign Class being the first series of starship to take full advantage of these access spaces for more than extraordinary maintenance. The technical complexity of the starship dictates the use of these spaces to maintain peak efficiency and affect proper repairs. 

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 center 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 on Deck 14. Two small single-person elevators, as well as a ladder on the opposite end, provide access to this catwalk. Controls for the various Fusion Power Plants, along with the Impulse Engines, are monitored from this deck. A lower level runs below Main Engineering on Deck 16 (Defector Control, Main Tractor Beam Control, Environmental Control, Anti-Matter Storage Pods, Deuterium Storage, and Secondary Power Couplings). Damage Control Teams are mustered here, as well as internal ship maintenance teams. Numerous consoles and replicators line this section, serving as auxiliary consoles for Main Engineering, along with providing engineering research space and secondary computer core support. Access to the Jeffries Tubes is provided in various places on all three levels of the Engineering Space. 

Engineering officers are responsible for observing and monitoring all the tasks that fall in the domain of the department.  This also includes conducting research in their specialties.  There are a couple of laboratories aboard the Akira Class starship that can be used by those engineers.  The labs are the Engineering Labs, Quantum Mechanics Lab, the Tactical Lab and from time to time the Astrophysics Lab.

 

The Engineering Department is one of the department within the Operations Division.  The staff of the engineering department consists of a corps of officers and enlisted personnel.  The Chief of Engineering (Chief Engineer) is the department head and also is a bridge officer. The staff of the engineering are specialized in sensors, theoretical physics, propulsion systems, anti-matter/matter fuel systems, shuttlecraft systems and much more.

 

Engineering personnel wear the standard Operations Division uniform which is typically mustard yellow.  Since the USS Tomcat is attached to the Starfleet Marine Corps, Marines, who are also engineers (or in the operations division) are denoted with a mustard yellow strip on their uniforms.


Typical crew compliment for Engineering consist from 100 to 160 personnel.  There are many specialized engineers that have team under them to get the duties of keeping a ship operational.  This includes Shuttle Maintenance, Environmental Controls and Senor Systems. The Engineering crew is divided to keep at least two members of the Engineering staff on duty at all times in the key areas.  They all have rotating duty shifts but during a red or yellow alert, off-duty staff could be called back to duty.

Engineering Staff Descriptions


The Chief Engineering Officer (or sometimes referred to as the Chief Engineer) is in charge of maintaining the ship's engineering functions. All junior engineering officers report to the Chief Engineer, since this person is the department head for Engineering. As such, he or she is responsible for the overseeing of all systems of a vessel and making sure that they are kept in prime operating condition. In addition, the Chief Engineering Officer is also responsible for coordinating operations with other departments regarding their instruments and systems. For example, the Chief Engineering Officer shall coordinate all tactical systems with the Chief of Security and Tactical Officer. Other related duties, such as ship wide diagnostics, are also coordinated through the Chief Engineering Officer. CEOs may also be called to participate in away team missions at the discretion of the CO and XO.


The Assistant Chief Engineer (or sometimes referred to as the Deputy Chief Engineer) assists the Chief Engineer in the daily work; in issues regarding mechanical, administrative matters and coordinating repairs with other departments. If so required the Assistant Chief Engineer must be able to take over as Chief Engineer, and thus must be versed in current information regarding the ship.


Engineer is the title to the several non-specialized engineers aboard of each vessel, as needed. They are assigned to their duties by the Chief Engineer and his Assistant, performing a number of different tasks as required (i.e. general maintenance and repair). Generally Engineers are assigned to more specialized engineering personnel to assist in their work as so requested by the specialized Engineer. There are typically 6 non-specialized engineers on an Akira Class ship.  These engineers could also be assigned to help when a head position is left vacant.

The Communications Engineer (also referred to the Communications Officer) is a specialized Engineer. Communication aboard a ship takes two basic forms, voice and data. Both are handled by the onboard computer system and dedicated hardware. The vastness and complexity of this system requires a dedicated team to maintain the system. The Communications Engineer is the Officer in charge of this team, which is made up from NCO personnel, assigned to the team by the Assistant and Chief Engineer. The Communications Engineer reports to the Assistant and Chief Engineer. 

 

The Transporter Systems Engineer is a specialized Engineer.  The Transporter Systems Engineer maintains the transporter systems and performs his/her duties with the assistance of a small team consisting of 2 Transporter Chiefs and up to 16 Transporter Operators/Technicians.  The Transporter Chiefs and Operators tend to the daily operations of the Transporters in every transporter room on the ship as well as those in shuttles, runabouts and the emergency transporter systems on any other vehicle that may contain such a system.  The Technicians report to the Chiefs and the Chiefs report to the Transporter Systems Engineer who then reports to the Chief Engineer.

 

The Matter/Energy Engineer is a specialized Engineer. All aspect of matter energy transfers with the sole exception of the warp drive systems are handled by the Matter/Energy Engineer. Such areas involved are transporter and replicator systems. The Matter/Energy Engineer is the Officer in charge of a small team, which is made up from NCO personnel, assigned by the Assistant and Chief Engineer. The Matter/Energy Engineer reports to the Assistant and Chief Engineer. There is typically only one person assigned to this position on an Akira Class ship and the Chief Engineer and Assistant Chief Engineer work to help cover this position along with any technicians that are seeking training in this specialty field.

The Warp Drive Engineer (or sometimes referred to as the Warp Propulsion Engineer) is a specialized Engineer. The complexity of the Warp Drive system of any starship requires engineers to monitor and maintain the different settings required for each ship. No two vessels have exactly the same system aboard, and all settings require careful maintenance and checks to ensure peak performance. On smaller vessels this task may be performed by the Chief Engineer, but larger vessel have a dedicated Officer whose role it is to ensure the Warp Drive system runs under any condition. A small team is often assigned to the Warp Drive Engineer, as needed, which is made up from NCO personnel, assigned by the Assistant and Chief Engineer. The Warp Drive Engineer reports to the Assistant and Chief Engineer. There are 2 Warp Propulsion Chiefs assigned as available to assist the Warp Drive Engineer along with typically 6 Warp Propulsion Specialists.

The Impulse Drive Engineer (or sometimes referred to as the Impulse Propulsion Engineer) is a specialized Engineer. The impulse systems of any starship require engineers to monitor and maintain the different settings required for each ship. No two vessels have exactly the same system aboard, and all settings require careful maintenance and checks to ensure peak performance. On smaller vessels this task may be performed by the Chief Engineer, but larger vessel have a dedicated officer whose role it is to ensure the impulse systems run under any condition.


A small team is often assigned to the Impulse Drive Engineer, as needed, which is made up from NCO personnel, assigned by the Assistant and Chief Engineer. The Impulse Drive Engineer reports to the Assistant and Chief Engineer. There are 2 Impulse Propulsion Chiefs assigned as available to assist the Warp Drive Engineer.  Then there are typically 6 Impulse Propulsion Specialists available to assist the Impulse Drive Engineer.


The Structural Integrity Engineer and Environmental Engineer are two specialized Engineers that work together. From a small ship to a large one, all requires constant monitoring. The hull, bulkheads, walls, Jeffrey's tubes, turbolifts, structural integrity field, internal dampening field, and environmental systems are all monitored and maintained by these officers and their team. 

The team assigned to the Structural Integrity Engineer and Environmental Engineer, is made up from NCO personnel, assigned by the Assistant and Chief Engineer. The Structural Integrity Engineer and the Environmental Engineer both report to the Assistant and Chief Engineer.

 

The Structural Integrity Team consists of 1 Hull & Frame Chief with up to 9 Hull & Frame Specialist under that position.  Then there is the Damage Control Chief who has up to 15 Damage Control Specialists under that position.  All of whom report to the Structural Integrity Engineer or the Assistant Chief Engineer.

 

The Environmental Engineering Team consists of 1 Gravity Systems Chief, 1 Atmospheric Systems Chief and 1 Support Systems Chief.  There are 6 Gravity Systems Specialists, 6 Atmospheric Systems Specialist who report to their respective chiefs.  The Support Systems Chief has 6 Replicator Technicians and 6 Waste Recovery Technicians working under him/her.


The Sensor Maintenance Engineer is a specialized Engineer. Dedicated to the maintenance and operation of the navigation deflector, guidance, helm, reaction control systems and all other sensor systems. This position typically reports to the Chief Engineer.  A small team is typically assigned to assist the Sensor Maintenance Engineer which would be made up of NCO personnel.  If this position is not available then the Assistant Chief Engineer and Chief Engineer head this title and have Engineer’s Mates and technicians working to keep this role manned.

The Shuttlecraft Systems Engineer is a specialized Engineer post. This Officer is assigned to the Shuttle Maintenance Deck (sometimes called the Flight Deck, but generally only if Fighter Pilot personnel are assigned), and is responsible for the service and repair of all small vessel assigned to the Starship. The flight deck must maintain a set number for craft at all times for evacuation purposes in case of emergency. 

A team is assigned to the Engineer in charge of Shuttlecraft Maintenance that consists of 2 Shuttlecraft Maintenance Chiefs and 5 Shuttlecraft Maintenance Specialists and is made up from NCO personnel, assigned by the Assistant and Chief Engineer. The Engineer in charge of Shuttlecraft Systems reports to the Assistant and Chief Engineer. 

The Computer Systems Engineer is a specialized Engineer. The new generation of Computer systems are highly developed. This system needs much maintenance and the Computer Engineer was introduced to relieve the Science Officer, whose duty this was in the very early days. The Computer Systems Engineer has a Computer Software Engineer and a Computer Hardware Engineer that serve under them.  A small team is also assigned to serve under the Computer Systems Engineer that is made up of NCO personnel filling the positions of 2 software chiefs, 15 programmers and 15 computer technicians as assigned by the Assistant and Chief Engineer.

 

The Auxiliary Engineering Officer is a position that is the Engineer who oversees the Auxiliary Engineering Specialist.  The Auxiliary Engineering Officer (typically an Ensign or a senior level engineering cadet – if in the Alpha Quadrant) works to help the Chief of Engineering maintain the secondary systems and the Auxiliary Engineering Specialists (typically NCO personnel or Ensign officers) work to keep the links for all back-up systems ready so if the need arises, the ship can depend on them.  If there was a crisis or an attack on the ship this group of specialist join in to assist the main engineering staff and function as part of the team.  The Auxiliary Engineering Officer reports to the Assistant and Chief Engineer.

The Engineer's Mate (typically an NCO) trains and supervises Engineering crewmen in departmental operations, repairs, and protocols; maintains duty assignments for all Engineering personnel; and is qualified to temporarily act as Chief Engineer if so ordered. The Engineer's Mate reports to the Chief Engineer.  There are typically 12 positons for an Engineer’s Mate on an Akira Class ship.  If there are opportunities, those in this position could request to focus on a specialty and move up in that area but still be utilized in a pinch to fill in elsewhere.

Engineering System Descriptions


The Warp Propulsion System is a RamJet Mark 2 Standard Matter/Anti-Matter Reaction Drive, developed by RamJet Propulsion. Information on this Warp Drive can be found in any Starfleet Library or Omnipedia.   The normal cruising speed is warp 7 thanks to innovaitons discovered and utilized in the General Electric Type 8 M/ARA Warp Drive outfitted in all Starfleet Vessels currently in service.  This upgrade prevents further pollution to subspace.  A maximum speed of warp 9.89 can be maintained for 12 hours.

The Impulse Propulsion System is the standard Akira Class mass drivers developed and built by HighMPact Propulsion. Output is comparable to Ambassador Class. Each engine (there are two impulse engines) can propel the Akira Class at speeds within the area known as Standard impulse operations. These speeds are limited to a maximum speed of .25c, with each engine working at .125c, due to time dilation problems. Quarter impulse is rated at .0625c, half impulse being .125c and full impulse is rated at .25c or 1/4th the speed of light.

The Reaction Control System is the Standard Version 4 magnetohydrodynamic gas-fusion thrusters, identical to thrusters deployed on the Ambassador Class starship. There are 24 of these thrusters spread across the primary hull to facilitate precise movement.  Each thruster quad can produce 4.2 million Newtons of exhaust.

 

There are twelve Transporter Systems located throughout the ship. 4 Personnel Transporters are able to beam up or out at a rate of approximately 100 persons her hour per transporter with a maximum range of 40,000 km and a maximum payload of 900 kg (1763 lbs).  4 Cargo Transporters are set for a quantum (lifeform) resolution of 1 metric ton, with a maximum payload mass of 800 metric tons for standard molecular resolution (non-lifeform) and a maximum beam up/out rate on the quantum setting of approximately 100 persons per hour per transporter.  Then there are 4 Emergency Transporters with a maximum range of 15,000 km (send only) with the range depending upon the available power. The Emergency Transporters have a maximum beam out rate of 200 persons per hour per transporter. So if all four transporters have power that is 800 people per hour for emergency beam out.

 

The Tractor Beam is a multiphase subspace graviton beam, used for direct manipulation of objects from a submicron to a macroscopic level at any relative bearing to the Akira Class. Each emitter is directly mounted to the primary members of the ship's framework, to lessen the effects of isopiestic subspace shearing, inertial potential imbalance, and mechanical stress. 

Each tractor beam emitter is built around three multiphase 15 MW graviton polarity sources, each feeding two 475 millicochrane subspace field amplifiers. Phase accuracy is within 1.3 arc-seconds per microsecond, which gives superior interference pattern control. Each emitter can gain extra power from the SIF by means of molybdenum-jacketed waveguides. The subspace fields generated around the beam (when the beam is used) can envelop objects up to 920 meters, lowering the local gravitational constant of the universe for the region inside the field and making the object much easier to manipulate. 

Effective tractor beam range varies with payload mass and desired delta-v (change in relative velocity). Assuming a nominal 15 m/sec-squared delta-v, the multiphase tractor emitters can be used with a payload approaching 116,380,000,000 metric tons at less than 2,000 meters. Conversely, the same delta-v can be imparted to an object massing about one metric ton at ranges approaching 30,000 kilometers. 

The primary purpose of the tractor beam is for towing or manipulation of objects.  The secondary purpose would be for tactical advantages as in pushing enemy ships into each other.

 

standard Akira Class main deflector dish is located along the ventral portion of the Akira Class's primary hull, and is located just forward of the primary engineering spaces. Composed of molybdenum/duranium mesh panels over a tritanium framework (beneath the Duranium-Tritanium hull), the dish can be manually moved twelve degrees in any direction off the ship's Z-axis. The main deflector dish's shield and sensor power comes from two graviton polarity generators located on deck 17, each capable of generating 128 MW, which can be fed into two 550 millicochrane subspace field distortion generators.

 

There are two computer cores on the USS Tomcat.  The primary core occupies space on decks 7, 8 and 9 far astern.  The secondary computer core, much smaller than the primary core, is located adjacent from Environmental Control on Deck 16.  The computer core on Akira Class starships are newer versions of the Galaxy Class Isolinear Processing Core.  The system is powered by a smaller, regulated EPS conduit directly from the warp core.  Cooling of the isolinear loop is accomplished by a regenerative liquid nitrogen loop, which has been refit to allow a delayed-venting heat storage unit for “Silent Running” when needed.  The requirements of the computer core rarely exceed 45-50 percent of the total core processing and storage capacity.  The rest of the core is utilized for various scientific, tactical or intelligence gathering missions.  The secondary computer core is to back up data in the event of a damaged primary core.  The Computer Systems Engineer and his/her specific engineering team, along with the Assistant and Chief Engineer and delegated Science officers and Command Officer are allowed access to the computer cores.
