A 10,000-ton cruiser trades speed directly against armour

A ten-gun, 8-inch cruiser can fit within 10,000 tons, but 33 to 34 knots requires accepting less armour than a 28-knot design.

Question

How much speed and protection could a 10,000-ton cruiser with ten 8-inch guns carry?

Short answer

About 33 to 34 knots with lighter protection, or roughly 28 knots if the designer prioritizes substantially more armour.

Notes

The proposed gun arrangement is technically feasible within a treaty-cruiser displacement. The decisive variable is the speed requirement rather than whether ten 8-inch guns can be carried at all. Designing for 33 or 34 knots consumes machinery weight and hull volume that otherwise could protect the ship. Accepting roughly 28 knots permits substantially more armour, so the final ship reflects an operational priority rather than a single unavoidable performance figure.
