Fromm-class Project K784 Guided Missile Destroyer

The Fromm class or the Project K-784 is a guided missile destroyer operated by the Colonial Pact Navy of the Colonial Pact. These vessels where introduced as part of a new line of modernized escort vessels starting in 00851 N.C.C. and have generally replaced their predecessor destroyer designs over the last several decades. Unlike the previous series of destroyer type vessels the Fromm and its various derivative classes where created with the intention of them operating both with fleets and on small formation or solo operations. As such the overall size of the vessel was increased but the armor protection remained the same, trading it for increased stores and a larger complement of sub-craft such as fighters and transports. Its brutally industrial design as well as the generally modular nature of its interior have allowed it to stay current even after thirty years of general production.

Shipboard Systems

The following are the ship's internal systems, the primary being the power, propulsion, electronics and support systems.

Power and Propulsion

The Fromm employs a mixed power/propulsion unit with a single reactor typically providing the startup power to ignite the ship's propulsion units, then these combined systems provide power to operate the ships systems at standard capacity and beyond. As a result these systems and the sub-components tied into them are located in close proximity, in the case of the Fromm class at the rear of the vessel further details are below.

Power

The starship employs a single large CLFFR type fusion powerplant employing a high density liquid metallic hydrogen fuel source fed into a ten meter diameter containment vessel. Employ electromagnetic and gravity pinching mechanisms to squeeze the stream to the point of high density fusion, the reactor effectively maintains a meter diameter sphere of fusing fuel akin to a small star during operations. The extreme heat and radiative energy given off by this body is converted directly into usable energy by the interior lining of the reaction chamber, with roughly three quarters of it going to this paneling with the rest being cooling and reaction stopping mechanisms.

However when the reactors are not active the ship can rely on a number of capacitor systems and long lived fission-thermal type power generation devices. The latter of which are located strategically throughout the ship to reduce the chance of all of them being knocked out by one attack or incident.

Propulsion

Three main propulsion units of the CMISFD-type provide forward directional thrust for the starship. Steerage is provided by a mixture of electromagnetic and mechanical ducting of the main drive array aided by strategically placed strike craft grade CMISFD-type thrusters. While active these drive systems also provide a percentage of their output as power to the ship's electrical grid. These systems are governed based on whether or not the starship is in atmosphere, however while in a gravity well the ship may employ its centrally mounted gravitic repulsion drive to hover in atmosphere. Effectively allowing it to conduct operations without the need to use direct thrust during the duration of its stay in a gravity well. For faster then light travel the destroyer employs a point to point fold drive of Colonial Pact design and manufacture. Like most systems of this type it is restricted to use outside of the central portion of a star's hillsphere.

Shipboard Electronics

Like most military starships the Fromm carries a wide variety of electronics, from its main computer system secure in its armored bubble below the ship's CIC to the thousands of miles of cables that run throughout its hull. Like all ships that traverse the vacuum of space these sensitive systems sit behind a myriad of defenses against the various hazards to the their existence, often the thickest and most cumbersome being the measures against radiation and EMP effects given off by various spacial phenomena.

Computational Systems

The primary central computer systems of the Fromm class consist of a pair of ENQ-901 type quantum computing mainframe computer cores fitted into the ship's command citadel hull, to be more precise the primary entrance to their mounting compartment consists of a hatch at the bottom of the bridge's display sphere. Effectively shielded and isolated from the ship with the exception of their power and data linkages (the latter of which can be disconnected if the network is compromised), these two cores serve as the primary computing power of the ship's systems. One is often detailed to handle the ship's normal operations while the other is dedicated to sensor data interpretation and weapons fire control.

If the ENQ-901 processors could be considered the brain of the Fromm class the ENQ-607 SSS3CM computing mainframe could be considered its nervous system. Composed of various networked computer systems varying in size and power, it effectively links the ship's primary computing core with the rest of itself. From those control systems intended for critical ship infrastructure to the personal terminals found inside each crew member's bunk, each are linked. In the event of network comprise the network can being air gapping parts of itself up to and include separating from the main computing cores.

Communications Systems

Like most vessels of its size and scale the Fromm has a variety of communications and network systems that operate both inside and outside of the hull. To begin with she has a shipwide data network consisting of miles of hardline linkages, these are aided by wireless data communications links placed throughout the crew accessible areas. A secondary more hardened network is employed for the ship's subsystems and runs on a completely different mainframe. Finally in the event of shipwide power being knocked out, a tietary voice only network powered by fission batteries allows for shipwide communication albeit unencrypted and voice only.

The ship mounts a wide variety of systems for external communication consisting primarily of laser and radio systems capable of transmitting at FTL or STL speeds. The highest priority use typically goes to the most powerful transmitter arrays used for fleet communication and interstellar communication with primary command networks. The second typically goes toward the ship's subcraft complement and the flight control guidance needed to operate them in a battlespace. Finally the ship employs dedicated arrays toward the support and communication operations of ground troops and infantry units using less powerful radio and laser systems.

Sensor Array

The Fromm like most military starships employs a mixed grouping of both passive and active sensor systems of varying types and performance. These sensors and arrays are listed and described below.

Mean Average Active Sensor Range - Target transient detection up to 140 astronomical units, high definition capable of positive target identification typically falls at 80 astronomical units depending on astrological conditions.
Mean Average Passive Sensor Range - Target transient detection up to 190 astronomical units, high definition capable of positive target identification typically depends on conditions and the size of a target. For a vessel comparable to the Fromm-class it can detect and identify up to 100 astronomical units away depending on conditions on what sort of activities the vessel is carrying out.

Electronic Warfare Systems

Like most military vessels the Fromm-class employs a mixture of electronic warfare devices of both passive and active natures in order to reduce the threat against guided munitions as well as reduce the effectiveness of enemy targeting systems on the ship. The three primary systems are listed and described below.

Grom-3 Active Jammer

A powerful shipboard multispectral jamming system that can operate in either a general emission mode or in a selective narrow focus mode. The Grom-3 is primarily targeted against hostile ship, strikecraft, and guided munitions as a means to confuse or simply burn out sensors employs to detect and track targets using the various waveforms of the electromagnetic spectrum. Its effectiveness can vary due to ambient conditions as well as the quality of enemy electronic counter-countermeasures.

Braza-3C Active Decoy Launcher

A factory sealed six shot launcher system that employs the starship scale mobile decoy drone system, it is used as a way to either enlarge the ships sensor signature by having them fly in close formation or as a means to distract or decoy away incoming strikecraft or ordinance. The latter of which can be done with either a straight line run, a pattern, or in a random adapative fashion depending on the enemy response to it. The Fromm has a total of six of these box launchers strategically mounted on the hull surface to provide full coverage from all the main ship approaches.

Sokol-4 Flare and Chaff Launcher

Consisting of individual eighty cell 100mm diameter munition tubes, each box launcher is loaded with half and half of each type of munition (chaff and maneuvering flares). Each flare can burn for up to two minutes and each chaff munition is capable of expanding out to a radius of two kilometers in zero-gravity conditions.

Life Support

Like most starships employed by the Colonial Pact the Fromm employs multiple life support and life maintenance systems under a hierarchy depending on the systems location and size. The first and the largest and most important of these systems is what is typically called the 'central life maintenance plant', effectively the core life support system with the largest capacity and is often the one under the most load. It is responsible for not only recycling, filtering, and monitoring air quality (full nuclear, biological, chemical, and nano-logical protection) but also handling the ships water supply with the same level of protection. As a result this particular system is almost as secure and defended against damage as the ship's munitions and central computer system, typically located nearby.

However this central system isn't the only one, each major deck or deck section on larger vessels or stations will employ its own smaller version of this system. While not quite as armored or defended these systems can be operated if the main system is brought offline, each tuned to handle the needs of its deck with a comfortable margin of error. Often they will be operated in parallel of the central plant to reduce long term strain, though they'll be operated a reduced capacity.

Finally each compartment features a smaller variant of the standard Colonial Pact Compact Life Support System (CLSS) used on vehicles and strikecraft, primarily as an emergency measure in order to keep anyone sealed inside alive until help can arrive or until they find a means of safely leaving the sealed compartment.

Protection

The following section covers the various passive and active defensive systems of the Fromm-class Destroyer.

Hull Armor

This section covers the hull armor of the destroyer.

Shielding

This vessel employs a Pact common type combined shield array with both active emitters, six to be precise, mounted to the exterior of the ship. These produce a 'hard' barrier type shield of transparent plasma in alternating onion like layers, effectively providing the vessel with a conformal 'armor' just off the ship's hull. The second is an internal field emitter which is wrapped around the inner skin of the ship's hull and also features further inner fields around the crew areas and critical ship systems. Known as the 'gravimetric field' it serves to protect the vessel against exotic energy and waveform threats

Armaments

Below are the various weapon systems with their mounting style and configurations described.

Main Battery Weapons

  • Two of these weapons are 'spinally' mounted with their bores being present on the front of the ship's bow, designed to work in tandem these two cannons produce a combined rate of fire of forty shots per minute.
  • Eight N2 205mm plasma cannons are mounted in four twin gun turrets with two on top of the ship and two on the underside, three of these turrets are capable of superfiring with the fourth on top of the vessel mostly intended for stern defense.

Secondary Battery Weapons

  • Mounted on the outside of the lower bow in a 'chase gun' configuration, there are a total of four guns in two turrets in a twin mounted configuration. These effectively serve as light 'chin guns' for the destroyer.

Point Defense/Anti-Aircraft Systems

  • 55A17-976 'Molniya' Mixed Munition Air Defense Complex
  • Sixteen of these systems are mounted in rows of four on both sides of the ship's central superstructure and above and below, they serve as the primary anti-fighter measure for close in defense in case strikecraft have gotten past the primary missile defense measures. Each are mounted in box containers set into the ship's hull.

Launchers and Munitions

Vehicle Compliment

Sub-Craft Handling System

Utilizing a mixture of hanging transport racks and maximum use of available space the Fromm class is capable of storing and deploying the following number of subcraft and ground vehicles.

  • 40x 27 Meter Length Sub-Craft Handling Slots
  • 5x 66 Meter Length Sub-Craft Handling Slots
    • These can be converted to handle craft in the 27 meter range effectively adding two new slots per converted 66 meter slot.
  • Space for up to eighty vehicles up to main battle tank in size.

Power Armor/ExoSuit Inventory

Generally scattered in designated storage compartments or in ready use configurations near troop residence blocs, they can also be found in other places throughout the ship depending on crew practices and command preferences.

  • Standard Configuration
    • 350x 'Vikhr' Light Power Armor
      • 250x Additional Units with embarked marine action group.
    • 600x 'Tigr' Heavy Power Armor
      • 850x Additional Units with embarked marine action group.
