Comprising more than 40 Royal Navy Clearance Divers and support staff, this ADG is split into two subordinate Area Diving Units, Northern Diving Unit One (NDU1) and Northern Diving Unit Two (NDU2) both located as a lodger within HM Naval Base Clyde, Faslane, to meet this wide, challenging and rewarding array of missions.

To aid Civil authorities, NDU2 provides a perpetual high readiness team of Explosive Ordnance Disposal (EOD), or Bomb disposal experts.

They collectively cover an expanse that starts from the high water mark in Liverpool and stretches out to sea clockwise around the British Isles to Hull encompassing Northern Ireland the Scottish Western Isles, Shetland and the Orkneys. This vast area was exposed to many bombing raids in WW2 both on land and at sea, and today the team continues to find and deal with such items of hazardous historic ordnance that would otherwise would pose a significant threat to international trade and the general public.

Northern Diving Unit 1 also has an Improvised Explosive Device Disposal (IEDD) responsibility which takes into account both Glasgow and Edinburgh cities and airports.

The other unit of NDG1 provides Underwater engineering support to HM Ships and Submarines within HMNB Clyde along with a worldwide deployable capability for In Water Maintenance and Repair of all Fleet units.

Unique to NDG is the support and manning of the NATO Submarine Rescue System which can be deployed at very short notice to attend to Submarine Emergencies.

A tri-nation system, NDG Divers work closely with French and Norwegian counterparts to ensure a readily available worldwide deployable capability.

All NDG personnel are trained in four different diving sets along with the ability to operate many underwater tools and equipments, including recompression chamber operations, to support their mission.
