A demanding shell test also becomes a demanding armour test. British armour work had already begun improving around the Orion programme and advanced through the King George V, Queen Elizabeth, and Revenge classes. Once shells are required to defeat harder plates at realistic angles, armour makers receive better evidence about where their own products fail. Projectile and protection design then advance together rather than as isolated technologies. That progression leads toward protection intended for the Admirals and, more clearly, the later G3, N3, and Nelson designs.

Better shell tests also drive better armour
Harder projectile trials improve both sides of the contest, accelerating British armour development from the Orion and King George V generations toward later capital-ship designs.
