In 1945 a new Guided Projectiles Establishment was set up under the Controller of Supplies (Air) and in 1946 development of all ongoing missile projects moved to the Royal Aircraft Establishment's (RAE) new Controlled Weapons Department, soon to become the Guided Weapons Department. They began considering the beam riding concept in partnership with the Telecommunications Research Establishment (TRE), the deliberately oddly-named department of the Air Ministry responsible for radar development. Over the next year, first Brakemine and then Stooge were moved to the RAE.
