Branch development over the past 50 years has seen the original Electrical Branch transformed on many occasions.
In 1961 it became the Weapons and Radio Engineering Branch, then the Weapons and Electrical Engineering Branch in 1965.
In 1979 a major restructuring of the Engineering trades resulted in the formation of the Engineering Branch that we know today.
Technological advances demanded the creation of sub specialisations to best serve each discipline and the Weapon Engineering (WE) Sub Branch was created to accommodate most of the personnel from the old structure with the remainder transferring to the new Marine Engineering Sub Branch as MEM(L)s.
The WE Sub Branch was further amended with the creation of the Warfare Branch in 1993 until the structure we know today was created in 2007 with the introduction of the ET(WE). CIS ratings were also formally integrated on 01 April 2015
