The Lyon reconstruction carries the planned battery of twenty-four 5.5-inch guns and six 4.7-inch guns alongside its quadruple main turrets. The design review then works through roughly three inches of main-deck protection and a thinner secondary deck before increasing the scheme for an imagined modernization. That distinction keeps the historical proposal separate from choices made to improve survivability in the game. The secondary battery shows how a battleship could fight lighter ships with weapons beyond its main battery. This completes the class's speed, machinery, and belt-armour picture with the rest of its protection and armament.

Lyon secondary guns and horizontal protection
The proposed French battleship's twenty-four 5.5-inch guns, six 4.7-inch guns, and layered deck protection show how much design weight lay outside the main battery.
