No. 90 Signals Unit RAF

No. 90 (Signals) Group was formed on 26 April 1946 and had its headquarters at RAF Medmenham in Buckinghamshire. It combined the signals, radio and countermeasures elements of Numbers 26, 60 and 100 Groups and No. 80 Wing RAF. Its purpose was to provide ground radio engineering, telecommunications, electronic warfare and the calibration and operation of navigational aids for aircraft. The Group became RAF Signals Command in November 1958, then becoming part of Strike Command, and reverting to No. 90 (Signals) Group on 1 January 1969. No. 90 Signals Unit was formed on 1 April 2006 under the command of a Group captain. Force elements from RAF Brize Norton, RAF High Wycombe and RAF Sealand relocated to RAF Leeming in Yorkshire between Summer 2007 and Summer 2009 as part of the creation of the A6 Communications hub. In December 2009 No 1 Expeditionary Radar and Airfield (ERA) Squadron becoming No 1 Field Communications (FC) Squadron, with personnel from the former Squadron being incorporated into the four FC Squadrons. No 1 (ERA) Squadron's role was to deploy, support and recover a wide range of airfield sensors, navigational aids and information infrastructure worldwide. This role was then carried out by specialist teams within the field Communications squadrons. No 5 Information Systems (IS) Squadron moved under the control of 90 SU Force Generation Wing (FGW). In February 2015, No 1 (Field Communication) Squadron was transferred to Engineering Support Squadron, FGW, becoming 1 (Engineering Support) Squadron. Additionally, the Trade Group 4 Aerial Erectors employed on the Field Communication Squadrons were centralised within the Aerial Erector Flight, FGW. ==Motto and badge==

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. To develop further the friendships and Morale they experienced whilst serving with the Unit. Being the first virtual Branch of RAFA, this initiative paved the way for similar Branches to be formed within the Association. It created a new method of promoting RAFA and demonstrating that it has as much relevance today as the day it was formed. The Branch is also the first to have its own website and this initiative also helps to promote the Association in a way that has previously not been possible. The RAFA Branch will ensure that the Unit Memorial, dedicated in 2008, and located at the National Memorial Arboretum will stand as a permanent reminder to those who lost their lives whilst serving in the Royal Air Force. ==References==
