Expeditionary Cruiser Os-C-04 Stellar Road Class

1. About the Stellar Road

This ship was designed by Carthage Project scientists and engineers as the command cruiser for the Viridian expeditionary fleet. The Stellar Road is similar in function to a battle cruiser. The ship can also carry modules containing cargo, fighter bays, or various other things. The ship boasts slightly better laboratory sections then that of any other Nepleslian ship and possibly Yamatain, save the bio-neural tech, etc. The ship also has a large main gun to clear space debris and to defend it and its fleet from enemy warships. The ship has adequate defenses for a deep space exploration vessel and can carry its own extensive range of modules, thus reducing the need for and strain on transport ships. These external modules also allow the ship to refresh its supplies by simply swapping them out for full ones from a transport as well.

2. History and Background

This lovely ship had been on the design board much longer then its little brother the Perry Class, and upon final approval of the Perry the command ship’s designers were able to finalize much of the design. As such, the dock workers and engineers were able to avoid many of the problems they had with the Perry’s construction and launch the ship just a few months after the first batch of Perry class ships had been completed.

5. Inside the Ship

Deck Layout

The ships decks are arranged one on top of another, stacked and are connected by lifts and maintenance corridors with ladders.

Compartment Layouts


There are 26 armories on the ship, located every other deck, fore and aft. These armories are fully stocked with the latest Nepleslian weapons as of YE 32. Each armory requires a ranking Sergeant or higher to access it.


The Stellar Road has a more modern bridge layout compared to most Nepleslian ships, with the captain situated at the center of the bridge with the helmsmen and tactical officer to the fore of him, and the science and engineering stations at the aft. The Stellar Road’s interface systems are comprised of touch-screen interfaces and tactile response key interfaces. The front of the bridges hull is comprised of a large view screen capable of projecting three dimensional images several feet in front of it along with a killer surround sound stereo system built into the surrounding bridge walls.

Captain's Suite

Officers Quarters: These rooms are slightly larger, with the captains being the largest, and are fully furnished with the latest in sleek plastic furniture. This furniture is also capable of folding flush into the room’s walls by the simple push of a button. All knick knacks, trophies, and adult items are neatly stored in retractable shelving.

Cargo Storage Areas

The ship has four large cargo holds located in the forward hull. Each hold is spacious and able to hold a sufficient amount of cargo and supplies for 2 years.

Crew Quarters

Each crewman has their own quarters for the long missions away from port. These are normally sparse, consisting of typical bed and shiny new plastic executive desk with a computer console on top, except for commanding officers whose quarters also have an array of shelving which often displays awards, commendations, and ship models. The quarters for marines and ground troops are comprised of stacked bunks (Made of metal with polyester mattresses) and personal trunks ( Made from pressed wood composite)

Crew Recreation

Commanding officers have their own washroom while there is one restroom for every 5 crew members. The ship has ten mess halls, seven fore three aft, each capable of holding 600 people.

Recreation: The ship has a recreation center with a spa, showers, basketball court, various combat simulators, video games, and a weight room. There is also a lounge that can hold 100 crew members and a stage.


Running decks 30 high at the aft of the ship, the Stellar Road class has one of the most efficient and powerful reactor systems to date. A minimal engineering crew of 30 can operate the ship under normal conditions. All 30 decks can be reached via ladder in the event of mass power loss.

Maintenance Conduits

The ship has an adequate number of maintenance corridors, which can be sealed either manually from inside the shafts or from various control stations on the ship. These corridors are made of some of the most resilient alloys that make up the ship, and are not very comfortable to climb thru due to their hard inner surface and use of ladders for vertical ascension at evenly spaced junctions.

Medical Center and Laboratory

*Section 1: The Stellar Road has one of the largest scientific laboratories of any ship in the expeditionary fleet, with the ability to accommodate over four hundred science personnel. There are eight decks in the forward section of the ship equipped with mission variable laboratory spaces, stellar cartography, and the ship’s twelve main medical bays. The ship’s medical bay serves the needs of the crew with a spacious infirmary, examination alcoves, and operating rooms.

*Section 2: This section, located between the rear of the forward hull and the cargo spine, contains 8 medbays, with 4 designed for battle casualties demanding immediate surgery. This section also contains most of the holding cells on the ship.

*Section 3: The third section of laboratories is located towards the rear of the ship between the cargo spine and engineering section. These include Biology/Xenobiology, Chemistry, Organic Chemistry, and other labs as well as two storage facilities for containment of specimens large and small and of various risk levels. The labs are among the most advanced in all of the Nepleslian territories.


Corridors are well lit, and the overall lighting changes to red when the ship is in combat. The floors are composed of a light colored composite while the floor is composed of plates made up of open hexagonal forms to improve traction

Power Armor Bays

The ships two fighter bays and large aft shuttlebay can also serve as Power Armor launch bays.

Shuttle Bays

The ship's exterior is equipped with one large shuttlebay located aft/dorsal which is a force field-contained opening in the hull. The bay makes it possible for shuttles to fly out into space at their convenience. This bay is normally sealed via a large sliding segmented door. The fighter bays are similar in construction, with two large bays located on the fore hull, one to port and one to starboard. The launch bays are staffed by an elite flight deck crew due to the amount of time the ship would spend away from port.


Located on deck 3, the wardroom is where the captain and commanding officers eat. There is a large wooden table that fills the center of the long, rectangular room, with comfortable chairs around it.

6. Ship Systems

Armored Hull and Hull Integrated Systems

*Hull: Composed of thick panels of Neutronium-coated steel around a carbon nanotube frame and Mercurite anti-radiation shielding, the Stellar Road’s hull provides fairly good protection.

*Airlock System: The primary airlocks are located at the fore of the vessel, both dorsal and ventral. An airlock is a device which permits the passage of objects, people, and the like, between a pressure vessel and its surrounding space while minimizing the change of pressure—and loss of air—in the vessel. The lock consists of two airtight doors in series which do not open simultaneously.

*Module system: The Stellar Road can carry 12 Modular cargo units. The module system is the measurement of standard cargo capacity. Each “Cargo Module” is 30m wide and 150m long. The modules attach on the port, starboard, dorsal and ventral section of the ships cargo spine, and can spin on an axis for artificial gravity if needed. The Modules can be accessed through its front and back end through the fore and aft of the ship, or when not spinning, through the UNI-V clamps on the spine.

*Unidirectional Gravitational Plating: plating on the roof emits a pseudo-gravitational field that is attracted to the plates on the floor pushing everything on the ship 'down'. This creates the false sense of gravity that permeates the ship

*Docking system: The Stellar Road uses the new Nepleslian UNIV-A Docking clamp systems, located midway on the spine of the vessel, which enables any smaller vessel, so equipped to be docked to and also carried along by the larger ship. The UNIV-A is capable of quickly docking and releasing any compatible ship attached to it via 4 magnetic clamps.

* Main Power: Primary FTL and weapons power is supplied through an aether tap system, which harnesses the fabric of space surrounding the ship and converts it into clean usable energy.

*Secondary Power: AM-M Reactor CRT VI The ship uses a high output fusion reactor assembly to efficiently generate power whilst consuming miniscule amounts of its hydrogen fuel. Fuel is stored towards the aft of the ship and at a safe distance, thou the reactor and can be ejected from the ship in an emergency. Two smaller reactors are located in the fore of the ship.

Computers and Electronics

Carthage Project programmed a Tactical Avatar AI into the ships main modular quantum computer. Through Holographic projectors located all over the ship, computer interfaces and screens can be materialized anywhere, although solid consoles are still there for backup. The ship can also be equipped with another computer module via an empty module slot to further enhance its combat capabilities.

*Subspace Mass Sensors: Subspace mass sensors instantly detect mass readings and movement of objects up to 1 AU (93 million miles) distance from the ship. The readings are used both for early warning and navigation when traveling at sublight speeds. The readings are not very detailed and cannot detect objects of less than 60,000 kg.

*Tachyon Scanners: Tachyon Scanners detect the disturbances in the graviton characteristics of normal space caused by the passage of ships traveling through hyperspace. Tachyon scanners also reduce the effectiveness of enemy missile jamming systems.

*Overlord Class Type B-1 Sensor Package: This sensor package is derived from the proposed Overlord class, yet eliminates many of the ECM components. Capable of scanning and processing readings from hyperspace, subspace, normal space and quantum fluctuations close to the ship as well as natural astral and stellar phenomenon. The package also includes sophisticated long range tactical sensors and ability to co-ordinate fleet maneuvers.

*Normal Spatial Communication: Laser and radio bands provide normal space communications.

*Hyperspace Communications: The hyperspace communications relay allows near real-time communication between starships and other vessels or planetary bases.

Emergency Systems

*Escape Pods: Escape pods are located primarily on the forward hull with enough to accommodate a crew of 1,300. An MEC-D is located at the Medbay for the injured or otherwise incapable of surviving in the pods. The pods have food and oxygen for 90 days and are on a 5 sharing basis. MEC – B also provided inside should the 90 days run out.

Life Support Systems

Enviro and Atmospheric generators/recyclers are located at various key points inside the ship. The ship is designed to be self-sufficient for 5 years, at which time it should dock to acquire fresh air and supplies. Air scrubbers and filters should normally be changed every month.


*Continuum Distortion Drive: (CDD) propels the ship at speeds many times the speed of light by generating continuum distortions and nesting them to create asymmetric peristaltic fields. This effect can also be tuned down to allow high maneuverability at sublight speeds in combination with small thrusters placed around the ship.

*Sublight Drive: The ship is equipped with three gravimetric drives that manipulate superstrings and the zero-point field to maneuver and accelerate to a far higher degree than other ships. By manipulating and “bending” superstrings, this drive system is able to create distortions in space/time that can be used to push and pull a ship in any given direction. An important byproduct of this means of propulsion is that the effect of inertia is also negated, allowing ships to accelerate, stop and maneuver at velocities that would crush a person using conventional ion propulsion.

Shield Systems

*Primary Shields: Collapsed Dimensional Shielding, a relatively new technology based on older super-string theories, wraps a single dimension around the ship, making it very difficult to damage with energy based weapons and some kinetic weapons. The Stellar road has 10% more power shields then the Perry class due to improved engineering.

*Secondary Shields: The Stellar Road Class is equipped with a Mercurite shielding system, which is capable of blocking most forms of electromagnetic radiation. A composite of copper and mercury developed in part by NDI scientists, it is used heavily in economic ship designs for basic hull shielding. These shields are normally kept up at all times.

Weapons Systems

Main Weapons

*Carthage Project Type VI Long Range Strike Cannon (Longbow): Mounted inside the forward hull, the ship must split in order to charge and fire its main gun. The Type 6 focuses its destructive power on a singular target (typically a warship), creating a destructive blast that can wipe out anything in a 45 mile cubic area. It is primarily designed to destroy individual warships outright instead of targeting entire groups of vessels. This weapon is used sparingly, either to clear large debris or defend the ship and its fleet from danger. This technology uses an anti-matter beam surrounded by tachyon particles to accelerate it past the speed of light before dispersing upon contact with the target where the anti-matter comes in full contact with the target. The concentration of anti-matter particles is varibile as well as the Location: Forward-facing ship hull mount Damage: Total destruction in a 45 mile cubic area. Range: Up to 1 AU (93 million miles) Rate of Fire: Once every 30 seconds.

*Type III Heavy Combined Pulse Cannon (2): Emitters in the ships hull which fire pulses of and in the “sea of energy” that is space. These pulses can cause aetheric generators to overload, and confuse ZPE-based sensors. At the same time, it also produces an immense electromagnetic pulse and ion bolt. The pulse cannon is designed to cripple other vessels. SECONDARY PURPOSE: Anti-mecha/Anti-fighter RANGE: .0.5 AU Damage: Moderate RATE OF FIRE: 5 shots per second.

Secondary Weapons

*Type 19 Gatling Plasma Cannons (24): The Type 19 Gatling Plasma Cannon is a new high-power, rapid-fire plasma cannon that operates on the same principles as the tri-focus plasma cannon but is placed in a four-barrel vulcan that fires plasma bolts in very rapid succession. The low-end estimate of the Type 19 plasma cannon's destructive power has been measured as the equivalent of a 25 gigaton fusion weapon. High-end estimates have been placed in the 55-60 gigaton range. Primary Purpose: Anti-Spaceship. Secondary Purpose: Assault. Range: 1 AU+ Rate of Fire: 20 shots/second.

*Phased Energy Arrays (96): Acquired technologies from the NDI, these weapons are standard of most Carthage Project ships. A Phased Energy Array is essentially a series of powerful beam cannons that utilizes a flux capacitor that not only can change the frequency of the energy blast, but can also phase the energy so it can exist in multiple dimensions simultaneously – which makes it capable of totally bypassing enemy shielding systems and applying their damage immediately to the enemy hull. The low-end estimate of the Phased Energy Array’s destructive power has been measured as the equivalent of a 400 megaton fusion weapon. High-end estimates have been placed in the 600 megaton range. PRIMARY PURPOSE: Assault SECONDARY PURPOSE: Anti-Warship RANGE: 1 AU+ RATE OF FIRE: 60 shots/second.

*Anti-Warship Missile Batteries (32): The cruiser is capable of launching missiles with ranges in excess of 1 astronomical unit (93 million miles), these weapons can be volleyed at ranges far beyond the guns of most enemy vessels. PRIMARY PURPOSE: Assault SECONDARY PURPOSE: Anti-Warship (Mecha Planetary Assault) RANGE: 1 AU delta-v RATE OF FIRE: The rapid reload system used on the missile launchers allows each tube to be loaded and fired once per minute. The launchers can fire both missiles and VF Assault Rockets at this rapid rate. PAYLOAD: 15,600 missiles in ready magazines.

Anti-Fighter Weapons

*Phoenix Arms Trc-1000 Pulse Cannons (48): For last-ditch point defense, the cruiser mounts fast tracking pulse cannon turrets that fire phased energy blasts at an extremely high rate of fire that are effective against all manners of mecha, missile, and other assorted targets. These weapons, however, are not effective against larger targets as they simply lack the sufficient power to deal damage. Low-end estimates for the TRC-1000 pulse cannon's destructive power has been calculated in the 700 gigawatt range. High-end estimates have been placed in the 105-130 terrawatt range. Primary Purpose: Anti-Fighter Secondary Purpose: Anti-Warship Range: 450,000 miles. Rate Of Fire: 4 pulses per second.
