Miscellaneous propulsion technology:[/b]
1900: Underway Recoaling
1906: Oil-firing boilers: Allows bunkers with larger than 10% percentage for oil
1915: Underway Oiling

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).

Light Cruiser Architecture - Main battery in deck mounts/casemates
1880: guns in single mounts or casemates, on side/centerline
1900: ammunition hoists, deck torpedo armament, superfiring mounts
1910: twin gun mounts (require hoists); powered gun mounts; unrestricted weapon armor
1920:  No restriction (high or low) on caliber of turreted guns

Destroyer and TB architecture - Top speed no less than 20kts, composite hull strength > 0.49
1880: single TTs - max 4, displacement 500t
1904: double TTs - max 8, displacement 750t
1908: triple TTs - max 12, displacement 1000t
1912: max displacement 1500t
1918: quad TTs, 2000t
1924: quintuple tubes, 2,500t

MTB Tech (Replaces ICE tech)
Motor Torpedo Boats

Tech years are :
1900, 1905, 1910, 1915, 1920, 1925, 1930, 1935, 1940:

*Note that a submarine of the 1920 tech level or newer may carry any mix of mines and torpedoes at a 1-2 ratio. So a sub might for instance carry a total of 20 torpedoes and no mines, or a total of 40 mines and no torpedoes, or a total of 10 torpedoes and 20 mines, etc.
