How an 8-inch turret grew heavier

How large a construction gap causes a navy to lose the ability to design effective heavy-cruiser turrets?

The key issue was requirement growth rather than a straightforward skills gap: designers added capabilities and ended with a heavier, differently optimized turret.

York and Exeter were grouped as a class even though the construction gap left them functionally different ships. The later turret problem was not simply lost skill. Its original specification included elevation to roughly 70 degrees and a possible anti-aircraft role. Designers then added stabilization, improved targeting, and stronger low-angle anti-ship performance while still asking for lower weight. The accumulated requirements produced a turret that was heavier and could no longer reach the earlier extreme elevation, a classic case of design creep.
