Fleet Radio Unit, Melbourne

FRUMEL code room

Fleet Radio Unit, Melbourne (FRUMEL) was a United States–Australian–British signals intelligence unit, founded in Melbourne, Australia, during World War II. It was one of two major Allied signals intelligence units called Fleet Radio Units in the Pacific theatre, the other being FRUPAC (also known as Station HYPO), in Hawaii. FRUMEL was a U.S. Navy organization, reporting directly to CINCPAC (Admiral Nimitz) in Hawaii and the Chief of Naval Operations (Admiral King) in Washington, D.C.,[1] and hence to the central cryptographic organization.[2] The separate Central Bureau in Melbourne (later Brisbane) was attached and reported to General Douglas MacArthur's Allied South West Pacific Area command headquarters.
