Blood hound missile base at Lee Point Darwin, now abandoned.
In the early 1950s the Department of Defence acquired Block 4873 to establish a radar and receiving station and by the 1960s there were numerous buildings surrounded by earth and sand embankments. These activities were related to the strengthening of the defensive forces in Darwin during the period of hostilities between Indonesia and Malaysia in 1963 (Alford 2004) and when the Indonesian Air Force violated Australian airspace. These activities included the permanent detachment of No 30 Squadron RAAF between 1965 to1968, a twelve gun battery which provided anti aircraft and seaward defences, six Bofors guns, surrounded by several two gun weapon pits, and the placement of Bloodhound MK1 surface to air missiles (SAM). No121 LAA was specifically formed as part of the 16 Air Defence Regiment for the Defence of Darwin during the Indonesian incursions. The radar station during this period was manned by the RAAF’s 2CRU (Central and Reporting Unit)
