The Royal Australian Air Force's No. 1 Combat Communications Squadron (1CCS) is a squadron within No. 95 Wing and is responsible for the provision of expeditionary Communications and Information Systems (CIS) to support Air Force and Australian Defence Force operations and exercises.
1CCS was formed on 20 September 1965 as the Air Transportable Telecommunications Unit (ATTU).
ATTU's role was to provide simple Communication Centres (COMCENs) in the field in support of air operations.
Over the years, the role has evolved to also include Air Traffic Control systems, navigational aids, and CIS required to establish a fully functioning military air base.
On 1 July 1999, after providing communications support for 34 years, ATTU was retitled No 1 Combat Communications Squadron (1CCS).
Emblem:
In front of a flash of lightning fessways a boomerang. Motto: Adroit (Dexterous, Skillful).
The flash of lightning is intended to refer to radio communications by the use of electrical energy signifying the basic function of the unit which is to provide tactical communications and navigation aids in support of air operations in forward areas.
The boomerang, in flight, refers to the use of air transportation as the normal means of deployment of unit personnel and equipment to the tactical areas and, consequently the need for all unit equipment to be air transportable.
