A Naval Information film about the rôle of the Engineer Officer in the Royal Navy.
The first sequence concentrates on the work of the Weapons and Radio Engineer Officer on board a frigate HMS Dido (F104) setting off on an exercise, with shots of maintenance and a description of how everything is coordinated: the sequence also shows the main wireless office, a Seacat missile being launched and a Westland Wasp helicopter in anti -submarine rôle. Other ships on the exercise include a Daring Class destroyer, aircraft carrier (angled flight deck and steam catapult), cruiser (firing Sea Slug missile). The film then goes on to explain that an Engineer Officer's career will not be confined to sea - other possible work/training is shown, including the Surface Weapons Establishment, the Naval Dockyard (working with civilian staff), involvement with companies on naval contracts, training at the Engineering college in Manadon, aeronautical engineering (Bullpup and Redtop missiles), submarines, studying nuclear physics at the Royal Naval College Greenwich (with the JASON reactor) and marine propulsion. "The responsibilities are great, but so are the rewards." [No end titles]
