German nine-gun cruisers could accelerate British upgrades

How would Britain respond to German 30-knot cruisers armed with nine 11-inch guns?

Britain would likely accelerate battlecruiser upgrades and reconsider whether some Queen Elizabeth-class modernizations should emphasize speed for interception.

Faced with German 30-knot cruisers carrying nine 11-inch guns, the Royal Navy would need ships able both to catch and overpower them. Renown, Repulse, and Hood would probably receive earlier modernization, with greater debate over whether Queen Elizabeth-class rebuilds should buy speed through new machinery rather than concentrate on armour and secondary batteries. A raider threat can redirect modernization policy even when it does not overturn the overall naval balance.
