An armor tech not related to the metallurgical aspects of the main tree, and not required as a pre-requisite to later techs on that main tech tree:

These are max capabilities. If there's a historical torpedo with less weight and lower performance, you can use that.

*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.

May 22, 2008 Edit: Adjusted 1911 BB/AC Architecture and added 1912 Armor

Feb 25, 2009 Edit: Several changes, per the "1/16" thread.

Apr 15, 2009 Edit: Clarified that SHP maximums apply to any motive power other than VTE.

Oct 28, 2009 Edit: Posted naval gun tech here, extended Torpedo, Destroyer and Submarine techs.

Jan 12, 2011 Edit: Added clarification on mine vs. torpedo carrying capability of 1920 tech and newer submarines. Replaced 1920 Light Cruiser tech
