How Many Guns Does that USN Battleship have?

A game duel between Dreadnought and a Montana-style design demonstrates how range, armour, and ammunition supply shape a battleship fight.

If Yamato construction continued and war waited until 1945, Britain might answer with successive Lion groups carrying nine, twelve, and eventually sixteen guns.

At extreme range, steeply descending shells make deck and turret-roof protection more relevant than the main belt.

The Tillman IV maximum-battleship proposal shows how gun count, armour, and stability compete for a finite displacement.

Checking A. D. Zinn's 1975 article changes the exercise from a 24-gun Tillman IV to Tillman IV-2 with fifteen 18-inch/45 guns.

Fielding 15-gun, 18-inch Tillmans would force Japan to rethink Yamato, but the infrastructure for a larger answer could become financially ruinous.

An armoured conning tower is useful in close fighting only when command practice puts the captain inside it.

The game's Yamato carries heavy armour, but its repeated opponents are unbuilt Montana- and Tillman-style maximum battleships.

Mounting twenty, then eighteen, 18-inch guns exposes the displacement, stability, and survivability costs of an extraordinary broadside.

A brief aside uses the HARP gun's joined 16-inch/50 barrels to show why extreme barrel length would complicate a battleship installation.

Two fictional game designs contrast an armoured American heavy cruiser with a Japanese counterpart carrying a 30-torpedo Long Lance broadside.

A 30-torpedo broadside forces attention to detection, manoeuvre, and the danger of closing inside the weapon's range.

Outside civil wars, it is very rare. The Battle of Tsushima is the clearest example offered, though Chinese and civil-war cases complicate a precise latest occurrence.

After the first cruiser duel, removing torpedoes frees weight for layered armour, bulkheads, anti-torpedo protection, and sensors.
