The successful use of radar by the Allied forces altered the course of
World War II. Much of the initial research into radar technology was conducted in Britain, but in an effort to boost the Allies' defences,
research findings were shared with other Commonwealth nations and the United States. These countries then began their own research.
Australian scientists successfully developed new radar techniques and advances upon existing theories which ultimately played a significant part in the Allies' victory.

While the Council for Scientific and Industrial Research (CSIR) was
responsible for radar research and the development of prototypes, other government agencies had responsibility for assisting in the development by approving and supporting the financial costs, procuring the appropriate technology and materials, manufacturing the machinery, or using the completed product.

The production of radar equipment was initially only undertaken by the Postmaster-General's Department, but due to the increasing
demand as the war progressed, private companies and other
government agencies also became involved in producing radar equipment.

From 1942 the Department of Munitions assumed responsibility for the production of radar equipment in Australia. It was also responsible for the supervision of private contractors who made radar equipment and arranged for the import and export of materials and completed machines.

The aspiration of the Radar Branch is to extend membership to RAAF
serving members. The Branch is grateful to have Air Commodore Chris Westwood who has excelled as a leader in the development of
modern radar capabilities in Air Force, particularly in the
introduction of the Airborne Early Warning 'Wedgetail' aircraft,
as the Senior RAAF Serving Member of the Branch.
