Drive Shafts:
1890: Direct Drives: The basic drive option. No bonus or penalty.
1906: Electric Drives: Allows for Electric drives. Takes a additional 25% of engine weight in misc weight and provides a 15% bonus to range plus improved compartmentalization (effects number of torpedo hits to sink).
1910: Hydraulic Drives: Allows for Hydraulic drives. Takes an additional 10% of engine weight in misc weight and provides a 5% bonus to range.
1912: Geared Drives: Allows for Geared drives. Provides a 10% bonus to range.
1912: Diesel Engines: Allows for Diesel engines to be used as part of mixed drive units or standalone power. Takes a additional 30% of engine weight in misc weight and provides a 75% bonus to range. Can be combined with Electric, Hydraulic or Geared drives (Bonus and penalties stack).

1902: All-big-gun ship with wing turrets OR Superfiring turrets (restricted axial firing arcs) [Pick one or both]
1905: Improved turret hydraulics, independent gun elevation, Torpedo Bulkheads, triple turrets
