SYDNEY, NSW DURING WW2
Shore Defence (Sh. D.) and Searchlight Control (SLC) were researched for the Australian Army at the CSIRO Radiophysics Laboratory at Sydney University, NSW. Their initial experiments commenced in April 1941.
The first prototype of the AA No. 2 Mk. 1 (Aust.) was delivered to the Searchlight location at Rose Bay Golf Links on 13 December 1941. The tests were a great success. Thus began the end of the use of Sound Location equipment. The Australian Army initially ordered 4 training units. Once Japan had bombed Pearl Harbor a further 50 units were quickly ordered. This new Mk. 1 equipment could locate an aircraft 30,000 yards away and assess range, bearing and elevation with reasonable accuracy.
