The Tribal class reflected interwar treaty and budget constraints, while the Battle class reflected wartime priorities. The newer ships did not have to conserve treaty destroyer tonnage in the same way. Their central compromise was to place as much useful anti-aircraft firepower as possible on a premier fleet destroyer while war was in progress. That difference explains why the Battle hull, armament, and systems arrangement looked unlike an interwar design optimized around negotiated limits.

A war-built destroyer, not a treaty compromise
Where the Tribal class balanced treaty limits and finance, the Battle class was shaped by the immediate demand for wartime anti-aircraft firepower.
