Jellicoe's path toward the fast battleship

Jellicoe's design work helped move the Royal Navy toward the Queen Elizabeth class and the idea of a battleship combining speed with battle-line protection. This was a contested vision because existing doctrine and commercial interests treated battleships and battlecruisers as separate products with separate roles. A fast battleship threatened the rationale for buying both. The moment gives useful context for Jellicoe's later discomfort with battlecruisers being committed as if they were fully protected battleships.
