Australian Submarine Sheean (SSG 77)


The submarine fleet of Royal Australian Navy is composed of six Collins-class boats. The HMAS Sheean SSG 77 is the fifth boat assigned to the fleet. She was named in honor to the Ordinary Seaman Edward Sheean. She is the only submarine of the class to be named for an enlisted sailor—the boat was laid down in 1994 and launched in 1999. As in the case of the Dechaineux, she was modified and fixed during the construction to solve some design problems detected in the first units of the Collins-class.

Operational Missions:

 

  • As one of the main training missions, the submarine participated in RIMPAC 02, where Sheean was able to penetrate the air and surface anti-submarine screens of an eight-ship amphibious task force, then successfully attacked both the amphibious assault ship USS Tarawa and the dock landing ship USS Rushmore.
  • In 2006, Sheean was presented with the Gloucester Cup for being the RAN vessel with the greatest overall efficiency over the previous twelve months.
  • Sheean was docked for a long maintenance period in 2008, but workforce shortages and malfunctions on other submarines requiring urgent attention have drawn this out.
    •  The submarine was formally returned to service on 23 February 2013.
  • On 16 July 2013, Sheean was damaged while berthed at the Australian Marine Complex.
    • Combi Dock III, a freighter owned by Dutch company Combi Lift and intended to supply the Gorgon gas project, broke free of moorings during a storm, and drifted into the submarine, causing damage to Sheean ’​s propeller and steering apparatus.

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.
