The Combined Communications-Electronics Board (CCEB) is a five-nation joint military communications-electronics (C-E) organisation whose mission is to enhance C4 interoperability and capability for the defence forces of its member nations and to provide leadership and influence across the wider C4 community, now and into the future. The member nations of the CCEB are Australia, Canada, New Zealand, the United Kingdom and the United States. The CCEB Board consists of a senior Command, Control, Communications and Computer (C4) representative from each of the member nations.
The CCEB is a member to the Washington-based Multifora consisting of, but not limited to, ABCA Armies, AUSCANNZUKUS, and The Technical Cooperation Program.
The Combined Communications Board (CCB) was established in 1941 based on high-level proposals for a structure to formulate combined communications-electronics policy. The CCB held its first meeting under Lord Mountbatten in Washington, D.C. on 24 July 1942 with representatives from the USA, UK, AUS, NZL and CAN. The CCB grew to 33 sub-committees established to consider all communication specialist areas. The CCB produced all combined communications-electronics publications used by the member nations. It also produced more than two million additional copies, in 12 languages, for use by CCB allies. CCB efforts continued after the war until 14 October 1949 when it was reduced in size and commitment with the formation of the North Atlantic Treaty Organization (NATO) and dissolution of the Combined Chiefs of Staff Organization. The United Kingdom Joint Communications Staff, Washington, and the United States Joint Communications-Electronics Committee continued to meet on a regular basis as the US-UK Joint Communications-Electronics Committee with representatives of Australia, Canada and New Zealand attending as appropriate.
