How did the dreadnought arms race between Britain and Germany develop before World War I?

The naval arms race between Britain and Germany was driven by Germany’s ambition to build a world-class fleet, a policy spearheaded by Admiral Alfred von Tirpitz starting in the late 1890s. Influenced by the naval theories of Alfred Thayer Mahan, Germany sought to establish a "risk fleet" (Risikoflotte) to deter British aggression or secure a decisive victory at sea, thereby asserting its status as a great power.123

The competition intensified significantly following Britain’s launch of the Dreadnought in 1906. This revolutionary "all-big-gun" warship rendered existing battleships obsolete, forcing other nations to accelerate their own construction programs. While Britain initially held a technical and numerical advantage, the race created a "naval scare" after 1908 as German production approached British levels.142

By 1912, Germany abandoned its aggressive four-vessel-per-year production rate, effectively ending the race, though the rivalry remained a source of tension. By the outbreak of World War I in 1914, Britain maintained a clear lead with 49 battleships in service or under construction compared to Germany’s 29.1
