Intended to give transport aircrews range and direction to a para-dropped pathfinder beacon (known as Eureka), this system also proved useful as an IFF transponder. Like many wartime microwave systems, the Rebecca-Eureka airborne guidance beacon originated as a British Telecommunications Research Establishment project that later benefitted from American advancements in miniaturization and manufacturing.
