DESIGN NOTES

  • large “wings” serve as heat radiators during normal operations

  • during combat, liquid coolant is used, let out through vents on wings leading edge and collected at the rear if possible (alternatively: nose to aft)

  • if needed, lithium heat sinks are used, pumped with heat until vaporized and then let out through vents

  • around 40% of total weight is in armour; armour itself is some 25% more effective than Asquilah counterparts

  • fuel tanks integrated into armour

  • emergency medical facilities are right next to shuttle bay

  • point defenses emplacements are Phased Particle Arrays, deployed in strips and capable of firing off-axis, much like Star Trek phasers

  • command center is deep within ship’s hull

  • hull itself is roughly pyramidal, long and slender to provide maximum thickness of armour to enemy DEWs as well as reflect any kinetics and space debris

  • observation deck is covered in glass for crew to go stargazing

  • decks are 4 – 4,5 m in height when plumbing and tubes in between are accounted for; decks themselves are 3 – 4 m

  • phased radar arrays on top and bottom of the ship are the main part of the superstructure

  • ship should fit within oblate spheroid (elongated ellipse in 2D)

  • calculate sublight acceleration capability based on mass and reactor output

  • calculate exact crew

    • HMS Dreadnought, 1906: 160,6 m, 18.410 t, crew 810 (5.114 m3 / 22,73 t per crewman)

    • HMS Vanguard, 1946: 248,2 m, 45.200 t, crew 1.975 (7.742 m3 / 23 t per crewman)

    • USS Bunker Hull, 1986: 173 m, 9.800 t, crew 400 (12.944 m3 / 24,5 t per crewman)

    • USS Zumwalt, 2016: 182,9 m, 14.798 t, crew 142 (43.088 m3 / 104 t per crewman)

    • Vanguard / ISS Aillil Aulom, 2886: 1.241 m, 14.283.887.326 kg (see below)

    • options:

      • +1,5 t / crewman / 40 years; 2886 – 1986 = 900 = +33,75 t = 58,25 t / crewman

      • +79,5 t / crewman / 30 years; 2886 – 2016 = 870 = +2.305,5 t = 2.409,5 t / crewman

        • crew = 5.378 (based on reduced weight due to armour)

  • minimum crew: 10 ( 1) captain’s chair, 2) helm, 3) navigation, 4) command and control, 5) weapons control – spinal, 6) weapons control – turrets, 7) weapons control – point defences, 8) electronic warfare, 9) communications, 10) engineering and life support)

  • emergency crew quarters in the citadel are 58 * 116 meters plus 30 * 116 m; taking around 20% of space for hallways and bulkheads, this gives living space of 8.166 m2, for almost exactly 1,5 m2 (or 4,5 m3) per crewmember; on longer cruises decks outside the citadel are used to provide more comfortable berthing while crew only moves to citadel during high-risk combat operations

  • on long range warships crew quarters outside the citadel give each crewmember a minimum of 54 m3 or 18 m2 (3 x 6 m)

  • on Aillil Aulom crew areas in the outer hull take three decks in area of 34 x 166 m, for 13.545 m2; four decks in area of of 52 x 130 m, for 21.632 m2 of usable space, eight decks in area of of 54 x 114 m, for 39.398 m2; four decks in area of 54 x 86 m for 14.860 m2 of usable space, four decks in area of 54 x 66 m for 11.404 m2 of usable space, four decks in area of 54 x 50 m for 8.640 m2 of usable space, two decks in area of 54 * 34 m for 2.937 m2 of usable space; this gives a total of 112.416 m2 of usable space or 337.248 m3; in total, each crewmember has 20 m2 or 62,7 m3 of usable space

  • with a total of 112.416 m2 / 337.248 m3 of usable space, Aillil Aulom can easily carry over 100.000 people in emergency, above normal capacity; converting unused room would add aditional capacity

PARTS OF THE SHIP

Command Information Center

Command Information Center combines functions of a CIC and bridge. It provides “organized collection, processing, display, competent evaluation, and rapid dissemination of pertinent tactical information and intelligence to command and control stations”. All vital intelligence from sensors, UAVs, scouts, intelligence agencies, central command etc. arrives there. Center of the room is dominated by a 3D holographic projection display, showing the area around the ship, and captain’s chair is right next to it. At front are navigation and helm stations, facing a viewscreen which can also be used to display tactical information if holographic display malfunctions. Other stations are grouped by function and located so that officers on stations can easily hear commands, surrounding the command desk in a amphitheatre manner.

Primary stations are navigation, helm, tactical / antiship weapons, point defense, electronic warfare, sensors, communications, engineering, security. As such, ship can in emergency be run by 10 people.

Observation Bridge

Observation bridge is ship’s bridge, used for when it is advantageous to have direct-eye view of the surroundings. It only has navigation and helm stations, as commanding from exposed position would be risky.

Tram

Tram is used for quickly reaching removed areas of the ship. While most important systems are located within the armoured citadel, many of these have backups located throughout the ship.

One Response to “Sci-fi battleship design”

  1. A'rhEngel said

    I have a suggestion for the main gun of the ship, if you don’t mind. Let me start by asking you a rhetorical question to which I’m gonna answer: what is the difference between a particle accelerator and a mass driver/rail gun/coil gun/Gauss gun? Nothing except the accelerated mass. So why not combine them? Our hypothetical accelerator could fire a sabot encasing a stream of charged particles. This could solve the disadvantages of both particle beam and kinetic dumb weapons. The disadvantage of a particle beam is that it diverges rapidly. This could be solved by building the sabot so it could contain the charged particles. The disadvantage of a kinetic dumb weapon is that it moves in a straight line. This could be solved by allowing the sabot to shape the containment field so that it uses the contained charged particles for acceleration and course changes. The simplest way to build such a sabot would be as an radio antenna that receives radio waves and rides inside a guidance beam. The whole process would resemble beam beam-riding Semi-automatic command to line of sight guidance only that the command beam would not trigger actuators but the shape of the containment field of the sabot. This way there would be no moving parts of the sabot, it would be an monolith antenna reacting to the guidance beam and probably very cheap to make. The beam need not be radio it could also be a laser if the material of the sabot would be capable to react to light by generating a magnetic field. I think this weapon would have a much greater effective range up to maybe a light-second (300.000km)
    I’m playing with such a combined weapon in my head, for my own sci-fi universe, but in my sci-fi universe the combined weapon would also be the main sub-light drive, particle shielding and heat management device and it would look like fins. 😀
