    BB(X) Montana X Class Adv Battleship

    I've been working on a advanced battleship that goes above and beyond the WW2 big battleships, while offering more to the U.S Navy. Compared to a 13 billion dollar nimitz carrier and a2 billion DD(X) for a very accurate price of 6.1 billion dollars this ship offer more for it's price. Capable of sustaining tremendous damage, with backeup systems and heavier guns than the original montana I've designed hopefully what will be the next step in my research on this subject of the Advanced Battleship as I have come to call this concept.







    Montana X Class BB(X)-70, U.S Advanced Battleship laid down 2005

    Displacement:
    86,050 t light; 87,826 t standard; 88,784 t normal; 89,550 t full load

    Dimensions: Length overall / water x beam x draught
    927.00 ft / 895.00 ft x 124.00 ft x 28.00 ft (normal load)
    282.55 m / 272.80 m x 37.80 m x 8.53 m

    Armament:
    12 - 18.10" / 460 mm guns (4x3 guns), 2,964 lbs / 1,344 kg shells, 2005 Model AGS
    Breech loading guns in Coles/Ericsson turrets
    on centreline ends, evenly spread, 3 raised mounts
    8 - 6.10" / 155 mm guns in single mounts, 113.62 lbs / 51.54 kg shells, 2005 AGS Model
    Breech loading guns in Coles/Ericsson turrets
    on side, all amidships
    6 - 8.00" / 203 mm guns (2x3 guns), 256.00lbs / 116.12 kg shells, 2005 AGS Model
    Breech loading guns in Coles/Ericsson turrets
    on centreline ends, evenly spread
    Weight of broadside 38,023 lbs / 17,247 kg
    Shells per gun, main battery: 150
    18- 57mm BAE Land and Armaments CIWS
    8-Submerged 650mm ADCAP Torpedo Launchers

    Peripheral Vertical Launch System-
    The solution consists of 65 four-cell PVLS situated round the perimeter of the deck, rather than the usual centrally located VLS. This would reduce the ship's vulnerability to a single hit.
    -Evolved Sea Sparrow Missile (Raytheon RIM-162)
    -SM-3 Standard Missile
    -Tactical Tomahawk or Tomahawk TLAM
    -Harpoon ASM

    Room for accommodation and workspaces is excellent

    SPY-3 with Aegis Mk7 Baseline 7.0b/CEC
    The radar suite will consist of a dual band radar for horizon and volume search, an L-band volume search radar (VSR) integrated with the AN/SPY-3 multi-function radar already being developed by Raytheon for the US Navy. The two radars are to be integrated at waveform level for enhanced surveillance and tracking capability. The AN/SPY-3 Multi-Function Radar (MFR) is an X-band active phased-array radar designed to detect low-observable anti-ship cruise missiles and support fire-control illumination for the ESSM and Standard Missiles.

    Rear Helo-deck can accomodate x3 AH-1 Super cobra gunships, however no hangar space is available to store them. Or a single Chinook can land for utility and cargo purposes. A cargo hatch is located just at the end of this Helo-pad. Munitions and cargo can be loaded directly to and from the helo-pad, and then transported to the munitions bunkers through a cargo lift located in this cargo bay.

    It seems to me that it doesn't stay afloat.

    I think I see what your saying. Your just reading it wrong. It's like...895 ft waterline and 927 ft overall length.

    "Block coefficient: 1.000"

    That's why the brick doesn't float.

    If the hull at waterline was barge-like in shape (no tappered ends) that would be 895X124X28=3,107,440 cubic feet. Sea Water at 35 cubic feet per ton (2,240 lb long ton used in ALL Naval Architecture) is a displacement of 88,784 tons which (curiosly) is exactly your Standard displacement figure.

    However, ships have pointy front ends and curved rear ends which reduces the volume considerably by about one third at least depending upon the final shape.

    With a 33% loss of volume, you have 2,081,984 cubic feet that translates to 59,485 tons of displacement.

    Sorry, 59,000 tons of displaced sea water will not allow an 88,000 ton ship to float.

    why not lose some of the heavy armor and replace the 18inch conventional guns with a larger version of the DD(X)'s rail gun. And if that still makes it sink just make it longer
