[Say, it isn't that bad!]

Edit: This spaceship may be upgraded to TL10; I will be looking into carriers for TL9.
Edit2: Current indications are that it is a capable, if expensive to refuel, fast battleship for Earth-Mars Alliance defence purposes. I've swapped the habitat and fusion reactor to place the habitat into a [core] section; this gives it PF 1,800 (18 vs cosmic rays). Also, I had incorrectly given the fuel for the "Advanced Fusion Pulse Drive" as "Hydrogen", rather than "Nuclear Pellets". In addition, an "External Pulsed Plasma" drive gets 4mps per fuel tank at TL9 (I had listed 2mps). The "move" column, second row, for the Starship Table listed 20mps instead of the correct 40mps.

Setting assumptions:

• Fast-pass interceptions:
  • are considered suicidal if performed on other warships (the velocity your missiles have towards them, is the velocity their missiles have towards you).
  • are considered Weapons of Mass Destruction if used against stations or planetary surfaces.
  • are considered terrorist attacks if used against civilian-populated stations or areas.
  • no-one wants to be the first to pull that genie out of the bottle.
• Nuclear weapons:
  • are considered MAD; use of nuclear weapons encourages use of nuclear weapons.
  • are considered Weapons of Mass Destruction if used against stations or planetary surfaces.
  • are considered terrorist attacks if used against civilian-populated stations or areas.
  • no-one wants to be the first to pull that genie out of the bottle.
• AI-controlled warships are roughly-equivalent to human-controlled warships; a little more performance, for more cost.

TL 9, Warship (battleship), SM+11 unstreamlined hull, 150 yards.

The Pacific battleship was rushed through design and production near the start of Solar War I, to provide a heavy warship capable of protecting both Earth, Mars, and "their dependent satellites".

Opponents of the Pacific design noted potential flaws, including:

• It could only survive a few hits from its own major battery to its front or central section.
• It could only survive a few hits from its own missile turrets (although its point-defence was considered sufficient to the task).
• It had a very limited combat engagement endurance.

After-action reports resulted in the confirmation of the following benefits:

• Its point-defence was sufficient against most missile fire.
• Its major turret gave it a substantial punch which could not be stopped by point-defence.

After-action reports resulted in the identification of additional flaws, including:

• Its fusion reactor seemed to exist for the sole purpose of powering its major battery.
  • Said fusion reactor provided twice as much power as needed, and should have been de-rated or switched for a fission reactor.
• Very vulnerable to energy weapons fire to the rear.

As such, refinements and new designs were being considered at the same time as the first Pacific battleships were constructed.
