Radar, Field Artillery, No 15, better known as Cymbeline, was a widely used British mortar locating radar operating in the I band using a Foster scanner. Developed by Thorn-EMI and built at their now-defunct site at Hayes in Middlesex, it was in British service from 1975 until about 2003 with the Royal Artillery. Cymbeline was more accurate than Green Archer and a lot more mobile. Although mortar locating was its primary role, it was capable of various other tasks.
