The Defence College of Electro-Mechanical Engineering (DCEME) was formed on 2 April 2004 as one of five Defence Training Establishments (DTEs) introduced to deliver coherent and cost effective training across the United Kingdom Ministry of Defence. DCEME brought together a number of separate Service training organizations, all of which were delivering forms of electro-mechanical engineering, with the aim of exploiting synergies to improve training delivery and output, and increase efficiency and effectiveness. DCEME reports to No 22 (Training) Group RAF.
