What might a Tribal-class destroyer look like under a 3,000-ton limit?
Short answerIt could carry four twin high-angle 4.7-inch mounts, producing a substantially more capable dual-purpose destroyer leader.
NotesThe extra displacement is used to solve the dual-purpose turret problem rather than merely enlarging the historical Tribal. Four twin 4.7-inch mounts able to elevate to roughly 75 degrees would give the ship a powerful surface and anti-aircraft battery. That change directly addresses the historical class's vulnerability to dive bombers. A larger treaty allowance could turn a destroyer leader into a more balanced fleet escort rather than simply a heavier gun platform.
