Collins-class Hunter Killer Submarine

The Collins-class Attack Submarine is a class of eight submarines in service in the Royal Australian Navy from 1996 onwards. The Collins-class takes its name from Australian Vice Admiral John Augustine Collins; all eight submarines are named after significant RAN personnel who distinguished themselves in action during World War II. The boats were the first submarines to be constructed in Australia, prompting widespread improvements in Australian industry.
 
Planning for a new class to replace the RAN's Oberon-class submarines began in the late 1970s and early 1980s. Proposals were received from seven companies; two were selected for a funded study to determine the winning design, which was announced in mid-1987. The submarines, an enlarged version of Swedish shipbuilder Kockums' Västergötland-class and originally referred to as the Type 471, were constructed between 1990 and 2003 in South Australia by the Australian Submarine Corporation (ASC).
The submarines have been the subject of incidents and technical problems since the design phase, including accusations of foul play and bias during the design selection, improper handling of design changes during construction, major capability deficiencies in the first submarines, and ongoing technical problems throughout the early life of the class. Working with several other countries (including America, Britain, Canada, and Japan) have helped in correcting most of the deficiencies in the Collins-class.
In 2003, the HMAS Waller attained the achievement of being the first diesel-electric submarine to sink a US nuclear submarine during a naval war games exercise.
In 2004, the Canadian government selected the Collins-class to be the base of their own indigenous diesel-electric submarine design (to be named the Victoria-class) on the conditions being that if Canada wanted to export them they needed Australian permission and had to pay a license fee, and any improvements the Canadians made could be adopted by Australia if they wished.
