The department made use of the experimental facilities of other government agencies, including the National Physical Laboratory at Bushy House and the Department of Scientific and Industrial Research (DSIR). Two sister organisations were formed: The Board of Invention and Research (BIR) which was established in July 1915 to support the Admiralty, and the Air Inventions Committee (AIC), which supported the Air Board once it became become fully operational in the summer of 1917.
