The Clearance Diving Branch is the specialist diving unit of the Royal Australian Navy (RAN) whose versatile role covers all spheres of military diving, and includes explosive ordnance disposal and maritime counter-terrorism. The Branch has evolved from traditional maritime diving, and explosive ordnance disposal, to include a special operations focus.[8]

History

The RAN has used divers on a regular basis since the 1920s, but it was not until World War II that clearance diving operations came to the fore, with RAN divers working alongside Royal Navy divers to remove naval mines from British waters, and from the waters of captured ports on the European mainland such as Hugh Syme, John Mould, George Gosse and Leon Goldsworthy all highly decorated.[9] RAN divers were also used in performing duties including reconnaissance of amphibious landing sites.[9] The skills learned in the European theatre were brought back to Australia, and used in the war against Japan.[9] After the war, RAN divers were used during the clean-up of Australian and Papua New Guinea waters of defensive mines.[9]

The utility of clearance and commando divers demonstrated during and after World War II prompted the Australian Commonwealth Naval Board to establish a clearance diving branch within the RAN in 1951.[10] [11] Divers were initially attached to the Underwater Research and Development Unit, based at .[12] In 1956, they were organised into a separate Mobile Clearance Diving Team.[10] [12] In March 1966, the divers underwent further reorganisation, splitting into two Clearance Diving Teams.[12] Clearance Diving Team 1 (CDT 1) was the operational team assigned to mine clearance and reconnaissance operations throughout the Australia Station, while Clearance Diving Team 2 (CDT 2) was dedicated to mine warfare in the Sydney area, but was not cleared for operations outside this area.[13]

In late 1966, Clearance Diving Team 3 (CDT 3) was established specifically for deployment to the Vietnam War to assist the overworked United States Navy Explosive Ordnance Disposal units, and to give RAN personnel in clearance diving work in an operational environment.[14] Sending CDT 1 or CDT 2, in full or in part, would have impacted on the teams' existing commitments, along with the continuity of training and postings.[15] CDT 3 was formed from available personnel; this was sufficient to keep a six-man team on station in Vietnam from early 1967 until early 1971, with six-month deployments.[16] CDT 3 was disbanded at the end of the Vietnam War, but the designation is reactivated for overseas wartime deployments, including in 1991 for the Gulf War, and again in 2003 for the Iraq War.[17]

Structure

The Clearance Diving Branch consists of:

For overseas operational deployments, the designation of Clearance Diving Team Three (AUSCDT3) is used for a specifically formed team.

The Royal Australian Naval Reserve has eight Reserve Diving Teams (ANRDT) which provide supplementary or surge capability in support of regular CDTs in addition to localised fleet underwater taskings:[18] [19]

Role

The Clearance Diving Branch force elements are:[20] [21]

1. Maritime Tactical Operations (MTO):[22] [23] [24]

2. Mine Counter Measures (MCM):[23] [26]

3. Underwater Battle Damage Repair (UBDR):[23] [27]

4. Task Group Explosive Ordnance Disposal (TGEOD):[28] [8]

5. Maritime counter terrorism-explosive ordnance disposal (MCT-EOD):[20]

A Clearance Diver may be posted to a Clearance Diving Team, Huon Class Minehunter Coastal ship, training position in the Australian Defence Force Diving School at HMAS Penguin and can apply to serve in the Tactical Assault Group-East (TAG-E).[31]

Since January 2002, Special Duties Units of Clearance Divers from AUSCDT1 and AUSCDT4 have provided the maritime counter terrorism element of Tactical Assault Group-East (TAG-E), attached to the Australian Army 2nd Commando Regiment, which became operational on 22 July 2002 to respond to terrorist incidents in the Eastern States of Australia.[32] [33] [23] [34] [8] Clearance Divers need to successfully pass the Army Special Forces Screen Test and then successfully complete specific elements of Commando Reinforcement Training before serving in either the water platoon as an assaulter or in the water sniper team in the sniper platoon.[33] [32] [35] Service in TAG-E is normally 12 to 18 months online before rotating back into the Branch with divers able to rotate back into TAG-E after 12 to 18 months offline.[8]

Selection and training

The RAN's diver training program is commenced with a 5-day Clearance Diver Aptitude Assessment, or CDAA, focused on demonstrating in-water confidence, physical endurance, mental resilience and attention, and supported through psychological assessment. CDAA is aimed to ensure officer and sailor clearance diver candidates have the right aptitude to commence the lengthy training program. Historically there have been a few variants, including the 10-day clearance diver acceptance test (CDAT), colloquially known as "hell week". During CDAT, candidates began each day at 02:00, and were put through over thirty staged dives designed to test their strength and endurance.[36] CDAT was shortened to a 7-day program, then into the current 5-day program with an increasing emphasis on in-water confidence and endurance.

Upon passing aptitude assessment, students must successfully pass the 60-week Clearance Diver Initial Employment Training course.[37] [38] In 2019, the first females graduated from the Clearance Diver Initial Employment Training course.[37] Clearance Divers who are promoted to Leading Seaman Clearance Diver complete the Intermediate Clearance Diver course and for Petty Officer Clearance Diver complete the Advanced Clearance Diver course.[37] [39] [40] Officers complete the Clearance Diving component of the Mine Warfare and Clearance Diving Officers course.[37] [39]

The MCT-EOD role requires clearance divers to be familiar with Tactical Assault Group (TAG) specialist insertion techniques including diving, fast roping and parachuting to be able to integrate into the unit to provide IED expertise.[20]
