In 1936, the Air Ministry took over Bawdsey Manor to further develop their prototype radar systems that would emerge the next year as Chain Home. The Army was suddenly extremely interested in the topic of radar, and sent Butement and Pollard to Bawdsey to form what became known as the "Army Cell". Their first project was a revival of their original work on coast defense, but they were soon told to start a second project to develop a range-only radar to aid anti-aircraft guns.
