Tsushima accelerated an existing direction rather than inventing the all-big-gun battleship. Britain expected other navies to draw similar conclusions, so Fisher's response was to turn work already in train into a ship before competitors could do the same. Guns, turbines, a dockyard, and preliminary construction arrangements were already available when urgency increased. The battle changed the pace and signalling value of the programme without being the sole intellectual origin of its design.
