Its purpose was to provide ground radio engineering, telecommunications, electronic warfare and the calibration and operation of navigational aids for aircraft.

No 1 (ERA) Squadron's role was to deploy, support and recover a wide range of airfield sensors, navigational aids and information infrastructure worldwide.

[6] No 5 Information Systems (IS) Squadron moved under the control of 90 SU Force Generation Wing (FGW).

[14] Until the amalgamation with 90 Signals Unit in 2006, TCW personnel could be distinguished by both their rank slides, embroidered with the letters 'TCW' and the Wing badge (the rock dove with lightning bolt).

Formed on 1 April 2010, the Branch was created to promote the relevance and aims of RAFA and also to be a focal point for current and ex-serving members of the Unit.

It created a new method of promoting RAFA and demonstrating that it has as much relevance today as the day it was formed.

[citation needed] The Branch is also the first to have its own website[15] and this initiative also helps to promote the Association in a way that has previously not been possible.
