AMES, short Air Ministry Experimental Station, was the name given to the British Air Ministry's radar development team at Bawdsey Manor (afterwards RAF Bawdsey) in the immediate pre-World War II era.
The AMES numbering scheme was often ad hoc, with some entries simply being other sets operating together.
[1] Three Landing Ship, Tank (LST) were converted into "Fighter Direction Tenders" (FDT), swapping their landing craft for Motor Launches[2] and outfitted with AMES Type 11 and Type 15 fighter control radar to provide GCI coverage for air defence of the D-Day landing areas.
[3] Post World War II in addition to the AMES Type XX designation new equipment was also allocated a Rainbow Code name during development, e.g., AMES Type 86 was allocated the code name Blue Anchor.
In addition, the manufacturing company, Ferranti, had its own internal and marketing name for the equipment, in this case, Firelight.
