At one point in the game model, dropping the design speed by roughly one knot saves nearly 1,300 tons. A slower 23-knot alternative can use its machinery savings for armor and other survivability improvements, while the 25-knot version retains greater tactical mobility. Propulsion demand therefore changes the available protection and stability margin across the ship. The calculation makes the displacement cost of a few additional knots visible.

One or two knots can buy armor and survivability
Dropping the design speed by roughly one knot saves nearly 1,300 tons in the game model, opening room for more armor and survivability improvements.
