Answer: HMS Dreadnought
Explanation: In 1906, Britain decided to retaliate by launching its first-ever dreadnought, HMS Dreadnought, which revolutionized naval power and is associated with a generation of successful battleships. However, this then prompted a reaction from Germany in the form of a proposed fourth naval bill, which called for four battleships to be built each year.
The naval race of World War I was an important competition between Britain and Germany for naval supremacy. Each nation raced to build more ships and capabilities, which led to an extreme increase in tensions between them. As such, historians consider the naval race between these two major European nations to be a main cause of World War I .
