Collins-class submarine
Template:RAN Collins Class submarines are a class of submarine built in Australia for the Royal Australian Navy. They were built by the Australian Submarine Corporation at Osborne, near Adelaide in South Australia. Some of the technology and design expertise came from Kockums of Sweden. The Collins class submarines replace much older Oberon class submarines in the Australian fleet.
The characteristics and range of Collins Class submarines have been tailored specifically for its defence and two-ocean surveillance role in the Navy. Designed to be as quiet as possible, Collins class submarines have been developed from five generations of submarines designed and built by the Swedish Navy.
These were expected to be the best conventional (i.e. diesel-electric, not nuclear powered) submarines in the world, but massive problems with noise and the weapons software suite have resulted in a series of delays and scandals. In 2005, it was revealed that the maximum diving depth of the Collins class had been reduced, following an incident in February 2003, when a seawater hose failed on HMAS Dechaineux at its maximum depth, flooding the engine room and almost sinking the vessel.[1] The maximum depth remains classified. The government claims that the problems of the Collins class are now solved or on their way to resolution. later in 2003, in a joint naval exercise, three Collins-class submarines reportedly "sank" two American Los Angeles class attack submarines and a US aircraft carrier, supporting the claims of defect resolution and combat effectiveness.[2]
One of the first submarine classes to be totally designed by computer, these submarines possess a vast range of features. They include a high-performance hull form, highly automated controls, low indiscretion rates, high shock-resistance, efficient weapons-handling and an optional air-independent propulsion system.
The submarine will move silently on electric power supplied by banks of new-technology lead-free batteries. The batteries are charged by three on-board diesel generator sets.
The sophisticated combat control system, which gathers its intelligence from sensors, processes the input and then launches and directs weapons, is considered to be advanced.
Each ship has been named after a distinguished former member of the RAN, some of whom have died for their country.
The submarines are based at HMAS Stirling in Fremantle, Western Australia.
