The Mjolnir-class is equipped with a two-layer shield system. The primary shields are Type-12, the largest allowed on any starship. They provide a Max Graviton Load of 2688 megawatts (MW) alongside a Max Dissipation Rate of 7.3x10^5 kilowatts (kW).

In the event the primary shields are compromised, a secondary Type-8 shield system is in place to protect the ship. The Type-8 shields provide a Max Graviton Load of 1344 MW and a Max Dissipation Rate of 3.7x10^5 kW.

Should both the primary and secondary shields fail, a network of emergency forcefields and bulkheads exists throughout the ship to maintain hull integrity. If emergency forcefields or bulkheads are in an area where the outer hull has been compromised, a Mjolnir is limited to speeds below warp factor four to compensate for the additional stress on the Structural Integrity Field.

The phaser systems on the ship were designed to enable debilitating volleys of near-constant phaser fire forward, and designers provided it with ample weaponry to enable that goal. A Mjolnir’s phaser systems are based around the necessity to first protect the flight deck. Four Type-VIII phaser turrets are placed forward, spread out around the hangar. One is placed on deck twenty, one on deck five, and two on deck seventeen, on either side of the hangar doors.

To protect the ship’s flanks, two Type X phaser arrays are positioned along the starboard and port sides of the ship, with each array having 250 emitters. These strips are located on deck twenty on both sides, near amidships.

Two additional Type X arrays are located on deck two and deck thirty-five aft. Each array has 250 emitters, and can fire in a 270 degree arc along any axis.

The ship’s final two Type X arrays are located on the ship’s surfaces, one dorsal and one ventral. The dorsal array is located immediately aft of the Flag Bridge, while the ventral array is located immediately aft of the torpedo bubble. Each array has 250 emitters as well, but due to their positioning, cannot have overlapping fields of fire.

The Mjolnir-class makes full strategic use of its four torpedo launchers. There are two launchers in the torpedo bubble on deck thirty-five that fire forward, and two that fire aft from deck eleven. With the torpedo launchers so far apart, a Mjolnir has two separate torpedo bays. Each torpedo bay is stocked with 80 photon torpedoes, 40 quantum torpedoes, and 30 reserve torpedo casings used for probes. Torpedo Bay 1 is located on deck eleven, and Torpedo Bay 2 is located on deck thirty-four, feeding the torpedoes down into the launchers.

In the event of a failure of the automated firing sequence, manual firing stations are set up on decks ten and thirty-four, but the rooms can only be opened by an officer with department head-level authorization.

In homage to the Kansas-class carrier, the Mjolnir-class was equipped with a Close-In Weapons System (CIWS). The CIWS system is designed to supplement the existing phaser system by concentrating solely on objects within 3 km of the ship, typically fighters, allowing the primary phasers to concentrate fire on capital ships outside that small target area. This also allows the CIWS to provide a higher rate of more concentrated fire, by reducing the area the phaser energy can travel.

The CIWS is made up of Type VI phaser banks and phaser arrays. There are eight phaser banks and five arrays. Each phaser bank has four emitters, and each array has 150. Each CIWS station is comprised of two phaser banks, with an array in between them, thus there are four stations. Station 1 is positioned on deck two, forward of the Flag Bridge. Station 2 is positioned on deck thirty-five, forward of the torpedo bubble. Stations 3 and 4 are positioned on the bottom of the fantail on deck fourteen. The fifth array is positioned in between stations 3 and 4.

Operation of the CIWS occurs in the CIC. Upon issuance of a tactical alert, the ship’s Chief Tactical Officer toggles the CIWS from “Inactive” to “Ready.” Automatically, the ship’s computer generates a 1000-kilometer sensor screen around the ship. Any ship designated as hostile that penetrates that screen is immediately targeted, and is fired upon by at least one of the five stations without any additional action by the CTO if it breaches the 3000m safety screen.

As a tactical vessel, the Mjolnir’s designers thought it was of paramount importance to create a large area onboard that could serve as a tactical command center for all combat actions, be they major fleet actions or simply the Mjolnir against any number of aggressors. Thus, the Combat Information Center was created. Located on deck twenty-three, the CIC is the size of a Starbase’s Ops Center.

In the center of the CIC is a ring of sensor information stations. Each station receives information on the battle area, and use holoemitters installed in the consoles to project a three-dimensional representation of local space. Using the information provided, the ship’s Captain can order weapons strikes on various targets, then see the results play out in real time on the holo-display. The CIC computers calculate the damage the strikes cause and update the tactical display accordingly.

The back wall of CIC is designated for use as a virtual viewscreen: a series of holoemitters are built into the wall to enable it to project an image of an area of space upon command. Upon the request of the CO or duty officer, the viewscreen can be activated to display incoming communications, sensor data, or merely a view of space.

In addition to the sensor stations and the virtual viewscreen, the CIC is comprised of stations showing the current damage level of the ship and its systems, allowing the command staff to instantly receive damage reports and alter their combat strategy as needed, as well as stations for the Security staff to know the status and location of any of the ship’s personnel.

The helm, operations, and tactical station form a horseshoe forward of the sensor ring, and face the holodisplay. The helm station controls the pitch, yaw, and roll of the ship. Operations provides reports on power levels and quick-summary damage reports that lack the depth of those provided by the wall DC consoles (see below), and tactical controls the ship’s weapons and shields.

Seating for the CO and XO is provided aft of the sensor stations in the form of raised seats that allow the command staff to take a load off their feet while remaining within sight of the holo-display. The walls of CIC – with the exception of the one designated for the viewscreen – are comprised of computer stations that serve as redundant links to various departments, such as Flight Ops for the Air Group, and Sickbay (which displays totals of casualties, separated into wounded and killed), and display Damage Control readouts, and also provide access to the CO’s Ready Room, the Flag Office, the Conference Lounge and the Briefing Lounge.

Two turbolifts serve the CIC regularly. In the event of a loss of power, the lift to CIC operates off a dedicated battery system.

Main Engineering on a Mjolnir is located on decks sixteen, seventeen and eighteen. It spans the entirety of the aft section on those three decks, using the space for the warp core and the matter and anti-matter tanks that provide the ship’s fuel. Main Engineering is also home to several spare parts lockers. There is a Machine Shop located on deck eighteen that, in conjunction with an industrial replicator, enables the engineers on the ship to produce their own spare parts for the ship and the fighter wings. The presence of the Shop reduces the number of times the ship has to visit Starbases for re-supply.

The Chief Engineer’s office is located on deck eighteen as well. In case of an emergency, the CE is able to eject the core and/or re-route power throughout the ship from his office, which can be completely sealed off from the rest of Main Engineering. This ability also is helpful in giving the CE a small amount of privacy should he desire.

The Mjolnir’s Security Office is located on deck twenty-nine. It contains a Squad Room, with desks for an entire shift’s worth of Security officers, a Brig, two interrogation rooms, and a small arms locker containing small-arms such as Type I and II phasers for on-duty security officers. The Squad Room contains a replicator.

The ship’s Brig is made up of six low-security holding cells comprised of a sixteen square meter room surrounded by bars and a Level Three forcefield, capable of holding four people at a time and four high-security containment cells comprised of an eight square meter room sealed off by a solid bulkhead and an entrance covered by duranium bars and a Level Five forcefield, capable of holding two people at a time. Any officer can access the Brig, but may only enter cells with the approval of a Security officer.

The interrogation rooms are where security officers question parties involved in the commission of crimes on board the ship. The rooms themselves are rather Spartan, containing two chairs and a metal table. An observation room is located between the two interrogation rooms, allowing Security officers or JAG representatives to listen in on interrogations.

The COS’ Office is located adjacent to Interrogation Two, and looks out directly into the Squad Room. Like the CE’s Office, the COS’ Office can also be sealed off from the rest of the Security Office. The COS’ office, however, contains a weapon’s locker that is only accessible with the COS’ Security Override Code and holds six Type III phaser rifles.

Also on deck twenty-nine, adjacent to the entire Security Office, are two holosuites that can be used to run training simulations for security officers. They are only accessible by the Security Watch Officer. The ship’s Armory and Marine Detachment are headquartered on this deck as well.

The Armory on a Mjolnir is located adjacent to the Marine Detachment’s headquarters, across the hall from the Security Office. Inside the Armory is a collection of anti-personnel weaponry substantial enough to provide weapons to half the ship’s crew. Weapons available in the Armory include Type III phaser rifles, Type IIIc compression phaser rifles, Type II phaser pistols, Type I phaser pistols, stun grenades, and photon grenades. The Armory also contains body armor designed to absorb and dissipate the energy of a phaser blast. Comprised of a vest, leg padding, and a helmet, this body armor is only issued to Marines and Rapid-Response Security teams who head into combat actions such as repelling boarders, boarding enemy vessels, or hostage rescue situations. Marine units also have access to such heavy weaponry as Tetryon Pulse Launchers, Isomagnetic Disintegrators, and Photon Mortars.

Access to the Armory is restricted to the COS, the commander of the Marine detachment, and any crew member with the rank of Lieutenant Commander or above. A quartermaster or quartermaster’s assistant is stationed in the Armory to record who withdraws what.

Across the hall from the Security Office and adjacent to the Armory is a room that contains the offices of the ship’s Marine detachment. Each Mjolnir is home to two Marine companies of three hundred Marines each, plus a small Headquarters company that brings the total number of Marines on board to seven hundred and makes the detachment a full Battalion. The Marine officers have offices on deck twenty-nine, where they can deal with disciplinary matters within their ranks, write up and file after-action reports, and meet with naval personnel about Marine involvement in upcoming missions. The detachment also shares time with the Security personnel in the training holosuites, and has its quarters on deck twenty.

The General Science Lab onboard the Mjolnir is located on deck four. It contains equipment for chemistry, physics, biology, and botany, as well as offices for all science personnel. The CSO’s Office is located here as well, and unlike the CE and COS’ offices, cannot be sealed off from the Science Labs. Finally, Deck four houses the quarters for all the Science personnel.

The Mjolnir’s two Cargo Bays are located adjacent to the Flight Decks on decks eleven through fifteen. One is located to starboard, the other to port. Though large enough to hold entire small-end cargo ships, each Cargo Bay is typically occupied by supplies loaded aboard at Starbases but not yet unpacked or catalogued. Each bay maintains a cargo transporter system to facilitate the collection of cargo. In the event of an emergency, the Cargo Bays can also serve as capture bays for the ship’s fighter compliment. There are doors on deck fifteen that allow the fighters landing in the Cargo Bays to make their way into the maintenance area.

As a carrier platform, the Mjolnir’s Tractor Beam is one of her most important pieces of equipment. Located on deck fifteen, below the Flight Decks, the tractor beam – with the paired 16 MW Graviton Polarity Sources producing 32 Mega Watts of Gravity Displacing Power – is effective up to a range (assuming nominal delta-v) of up to 20,000 kilometers. This allows the ship to have a rudimentary assisted-landing system, where pilots – aided by the Tractor Beam – enter the 20,000 kilometer range, decelerate, and allow themselves to be pulled in to the mustering area, at which point the pilots activate their thrusters and maneuver through the forcefield, land the craft, and taxi to their berthing space. This assisted-landing system, however, does not operate under combat conditions due to limitations on the number of fighters it can pull in at once.

The Mjolnir-class has a large and elaborate transporter system. Due to the immense size, having a few centralized transporter rooms was quickly determined to be infeasible for dispatching boarding parties, SAR-teams, or even receiving dignitaries. Thus, the transporter system on the Mjolnir-class was departmentalized instead.

There are eight standard transporter rooms aboard a Mjolnir. The first two are located on deck two, and are typically the transporter rooms used for the reception of dignitaries. From these two transporter rooms, the dignitaries may be directed to VIP Quarters, located on deck two, or the Conference Lounge adjacent to the Flag Bridge on deck one.

The second two are located on deck eight, and are general purpose transporter rooms, beaming crewmembers to Starbases or other ships for purposes not related to capture or assault.

The final four are located on deck twenty-nine, adjacent to the Security Complex, as well as the headquarters of the Marine detachment. From here, boarding parties can be dispatched to enemy vessels, or friendly vessels in need of assistance repelling boarders. This allows a Mjolnir to more quickly saturate an area with its teams, and provides a greater opportunity for success.

The emergency transporter rooms aboard the Mjolnir class are primarily for the use of the Medical department. There are a pair that serve the Alpha Sickbay on deck three, and a pair that serve the Beta Sickbay on deck twenty-six. This allows for greater response time by the ship’s medical staff to medical emergencies, and in turn, boosts the injury survival rate.

The standard transporter rooms have six pads each, and a refresh rate of sixty seconds. The emergency transporter rooms have eight pads each, and a refresh rate of thirty seconds. Pattern buffers are stationed on the deck below each set of rooms.

There are twelve turbolift tubes onboard a Mjolnir-class ship. Emanating from a central hub located on deck thirty-five, the turbolift system is the best way to travel on a Mjolnir. It may take five minutes to get from a job doing maintenance on the deck thirty-five phaser array to deck seven for lunch, but it’s much faster than walking.

Each Mjolnir-class ship has two. As a combat ship with a large crew, it is expected that the ship will see a significant number of battle casualties with each engagement. With that in mind, the designers incorporated two large Sickbays, Alpha Sickbay on deck three, and Beta Sickbay on deck twenty-six, to ensure the best medical treatment possible.

Alpha Sickbay is the Main Sickbay. It has seventeen biobeds in its main treatment ward, with an additional fifteen beds each in its surgery suite and recovery ward for a total of 47 beds. Beta Sickbay, however, is larger because its location relative to the most populated areas of the ship makes it the default sickbay for crewmembers in Engineering or Security.

Beta Sickbay is also the Combat Sickbay. It has twenty biobeds in its main treatment ward, with an additional fifteen each in its surgery suite and recovery ward for a total of 50 beds. During combat, it operates on a triage system, where medics treat green-level patients, nurses tend to yellow-level patients, and doctors work on red-level patients.

The CMO’s office is located in Alpha Sickbay, in an administrative suite adjacent to the main treatment facility.

Every set of quarters aboard the ship, as well as the Conference Lounge, the Crew Lounge, the Crew Mess, the Pilot Briefing Lounge, the CO’s Ready Room and the CIC is equipped with a replicator. Each replicator is capable of producing any food or clothing item.

Crew Quarters are located throughout the ship, though are mostly contained in the upper decks. VIP quarters and Command quarters are located on deck two. Quarters for Department Heads and medical staff are located on deck three. Quarters for science staff are located on deck four. Junior officer and enlisted quarters are located on deck seven. Quarters for flight crew are located on decks sixteen and twenty. Quarters for Marines are also on deck twenty. For purposes of assigning quarters, pilots are considered flight crew, and placed in enlisted quarters on deck sixteen. Maintenance crews are placed in enlisted quarters on deck twenty.

VIP and Command quarters are large suites, comprised of a large living/reception area, an office area with a workstation, a kitchenette with a replicator, a bathroom, and a bedroom. The CO’s quarters, in addition to that, have a hot tub adjacent to the bathroom, capable of seating eight people comfortably.

DH quarters are staterooms comprised of a medium-sized living/reception area with a computer workstation, a bathroom, and a bedroom. DH quarters also contain a replicator.

Junior Officers are billeted in pairs, in rooms comprising a small living/reception area, a shared bathroom and separate bedrooms. The Junior Officers’ quarters share a replicator.

Enlisted officers are bunked in groups of four. Enlisted officers’ quarters are comprised of a bedroom with two sets of bunk beds. Each bunk has two large drawers beneath it for storage of personal items, and enlisted officers share a closet at the head of the bed for uniforms. Every two enlisted officer’s quarters shares a bathroom in between them.

Marines are bunked in enlisted officers’ quarters on deck twenty. There are exceptions, such as the company COs (billeted together in Junior Officers’ Quarters) and the Battalion CO (solo suite in DH Quarters).

The Mjolnir-class is equipped with four holodecks: two on deck six, and one each on deck eight and deck twenty-five. Seven holosuites are scattered throughout the ship as well, two on deck six, one on deck twenty-eight, two on deck twenty-nine, and one each on decks thirty-one and thirty-two.

The Crew Lounge is located on deck eight, with seating for 500 people. It has a staff of waiters to quickly and personably provide food to crewmembers. Seating is available by reservation, or by walk-in. Reserved seating is, however, the seating closest to the large windows, and thus has the best view.

Just below the Crew Lounge, on deck nine, sits the Observation Lounge. The O-Lounge only seats 100, and is served by the same wait staff as the Crew Lounge. All seating in the O-Lounge is reserved, and the O-Lounge can be booked for parties.

Located on deck twenty-one, the Crew Mess provides an informal setting for crewmembers to eat, as an alternative to the Crew Lounge for below-decks crewmen. The Crew Mess has seating for five hundred people, and serves three meals daily in a buffet style. For those who wish to eat something other than what is on the buffet, a replicator is available.

The CO’s Ready Room is located adjacent to the CIC on deck twenty-three. The Ready Room is equipped with a small coffee table with three chairs for informal meetings, a desk/workstation with two chairs for formal meetings, a small head to freshen up before meetings, and a display area. What is displayed is Captain’s Prerogative. The Ready Room also has a replicator, and a small sofa/pull-out bed the Captain can use to catch a quick nap.

The Conference Lounge is located adjacent to the CIC on deck twenty-three. The Conference Lounge is equipped with a long table with seating for ten. Each seat has a computer terminal allowing them to read over briefing documents and view complimentary information to any presented on the large computer screen at the head of the table. A replicator is also provided in the Conference Lounge for use of crew members in need of coffee or a Danish before a briefing.

The Briefing Lounge is located adjacent to the CIC on deck twenty-three, next door to the Conference Lounge. It is a somewhat smaller copy of the Conference Lounge, and only seats six, but allows the senior staff members stationed in CIC the ability to discuss mission issues out of earshot of the rest of the CIC crew. It can also be used for consultations with allied or enemy forces, or as an impromptu War Room.

The Flag Office is located adjacent to the CIC on deck twenty-three, next door to the CO’s Ready Room. It provides the Flag Officer, should one be embarked, a place to work from without imposing on the CO. It is outfitted with a desk, two chairs, and a replicator.

The Counseling Center is the home of a Mjolnir’s CNS and staff, devoted to ensuring the mental health of all crewmembers on board. Located on Deck Thirty-Three, the Counseling Center is equipped with standard psychiatric diagnostic and treatment equipment.
