Laser Airborne Depth Sounder Flight RAN


The Laser Airborne Depth Sounder Flight was a unit of the Royal Australian Navy. Unlike the rest of the flying units of the RAN, it was not controlled by the Fleet Air Arm from, but instead fell under the operational control of the Australian Hydrographic Service at, providing a platform for the operation of the laser airborne depth sounder system.
LADS Flight conducted its last sortie on 7 November 2019.

History

In the 1970s, the Royal Australian Navy's Hydrographic Service was still limited in its ability to survey the vastness of Australia's coastal waters, and was still producing charts on areas where surveying was incomplete or had not even taken place. As a consequence, the RAN began to search for a way of effectively surveying the Australian coastline from the air, which led to the development of the Laser Airborne Depth Sounder system by the Defence Science and Technology Organisation, a part of the Australian Department of Defence, with trials beginning in 1977. In 1992, a new unit was formed to operate the system, the Laser Airborne Depth Sounder Flight, with the LADS system fitted to a highly modified Fokker F27 aircraft. This aircraft was subsequently replaced in 2009 by a modified Bombardier Dash 8.

Operation

The LADS Flight was a joint operation between the Australian Hydrographic Service and the Fugro LADS Corporation, part of Fugro a Dutch corporation, which also runs hydrographic operations for the private sector. The aircraft itself was owned by the Fugro LADS Corporation, which also provides the flight crews and system maintenance technicians. Aircraft engineers came from the civilian contractor, Cobham Aviation Services Australia, while the hydrographic specialists are serving members of the RAN. The flight was stationed at Cairns in the far north of Queensland, but could be deployed to other locations for up to three months at a time; the aircraft had an operational endurance of up to seven hours for operations close to its base, reducing to four hours on station at a distance of up to 300 nautical miles.
In December 2016, the aircraft deployed to the South Island of New Zealand to assist in surveying the coast following the Kaikoura earthquake.
