Technological development does not follow an inevitable sequence from one invention to the next. Several powers researched radar in the 1920s and 1930s, but their priorities and funding directed the same underlying technology towards different tasks. In the Chain Home example, Germany and other powers interpreted the British system as a means of watching shipping while Britain pursued surface and air detection in parallel. Britain had enough research centres to support both efforts. Misreading the better-funded British programme could discourage another country from pursuing air-search radar itself.

Chain Home and assumptions about rival radar research
Mistaken assumptions about Chain Home illustrate how research priorities could diverge even when several countries understood the same radar technology.
