Australian submarine Dechaineux SSG 76


The Collins-class submarines are operated by the Royal Australian Navy. Among them, the HMAS Dechaineux (SSG 76) was the fourth submarine built for the navy. She received her name from Captain Emile Dechaineux, the submarine was laid down in 1993 and launched in 1998. She suffered some modifications during her constructions to fix some problems that affected systematically to all Collins-class boats. As a major accident, in 2003, a seawater pipe burst while Dechaineux was submerged deep. This caused a nearly resulting in the loss of the submarine.

Frigate surface Force (11): The principal striking force of the RAN comes from the eleven frigates of the surface force: eight of them belong to the Anzac class and the rest (three) are units from the Adelaide class.

 
Submarine Striking Force (6): The RAN operates six Collins-class submarines. Due to technical and manpower problems these submarines might be replaced in the future by Japanese Soryu-class submarines.

 
Amphibious Force (3): There are a huge variety of amphibious warfare units, which include two Canberra-class landing helicopter dock ships and the landing ship HMAS Choules.

 
Patrol Boat Force (13): There are thirteen Armidale-class patrol boats that perform coastal and economic exclusion zone patrols.

 
Mine Hunting and Warfare Force (4 + 2 in reserve):
There are four Huon-class vessels that are used for minehunting and clearance (another two are commissioned but in reserve since October 2011).

 
Replenishment Force (2 + 6 survey duties):
The task for replenishment at sea is provided by two ships, Sirius and Success. In addition, there are two Leeuwin-class and four Paluma-class vessels perform survey and charting duties.

 
Training Units (1 + 1 support vessel + 2 patrol boats):
The RAN operates the sail training ship Young Endeavour, the support vessel ADV Ocean Shield, and two Cape-class patrol boats. The latter ones are acquired thanks to the Australian Border Force.
