This is a rule set for WW2 naval combat written in French.
This is not a classic wargame, as it has no mapboard or counters, but cards for ships. The rules are very simple. Basically, blank sheets and pencils are the only things needed to start playing. Miniatures are not needed to play but can be used.
The main difference with other naval rules is that Amirauté (Admiralty) is not purely a tactical game. Although it has detailed guns rate of fire, penetration, rules for aircraft, naval bombing for operational scenarios and campaign games are included. For example, you can play the exactly same scenarios as Avalon Hill's Flat Top, not only the battles.
What you need to play:A referee is strongly recommended for a better gaming experience.
Naval units: each ship is described on a card with its size (length, width), armor, detailed weaponry (diameter, range), max speed, defensive value (calculated from tonnage, vertical and horizontal armor, age).
Air units: air units are defined by their max speed, range, weaponry and defensive value.
