Link Room VII – Light Warning Radar Display @ NASAM

The D Day planners decided that a light, simple radar, easily moved, was needed for D Day and the subsequent battles. So was born the AMES 6 family of radars, also known as TGRI 5109 or TGRI 5124. The complete radar and operating crew could be carried in a 3-ton lorry. If radio communication facilities were needed, it required a further lorry.

Indicator Unit Type 74 was the display unit covering a 50-mile radius.  This unit is on show at the Norfolk and Suffolk Aviation Museum.

6 Mk III            2910C              Converted to Mk V

6 Mk V             2910C              Converted from Mk III

TGRI 5124 was also referred to as AMES Type 6.

Some books refer to 11 different versions being fielded during the campaigns around the world.
