What if the Imperial German Navy had pursued a night-battle doctrine from 1900?
Short answerIt could make Jutland's night action more effective and dangerous, but limited sensors and revealing illumination would keep the doctrine unreliable.
NotesThe counterfactual gives the Imperial German Navy a dedicated night-battle doctrine beginning in 1900. That preparation would make the night phase at Jutland more dangerous for both sides. The main constraint is technology: Second World War radar and sensors could support repeatable night tactics, while First World War forces depended much more on illumination and visual contact. Measures intended to find the enemy could therefore reveal the German ships as readily as they exposed British targets.
