For years Australia has sort of let their Collins class subs go wanting, lacking funding and struggling to maintain crews. Now that other countries in the region (such as Malaysia) are working on establishing their own sub fleets, the Aussies are interested again.
Australia has reported that they plan to build the world’s most lethal conventional
submarine fleet, capable of carrying long-range cruise missiles and futuristic midget-subs, to combat an expected arms race in the region. Defence minister Joel Fitzgibbon says submarines provide a vital military capability for Australia.
“We’ve always been superior to our neighbours to the north but south-east Asian countries have developed and grown their wealth and now have access to better technologies,” he said. “We need to start planning now; in fact we should have started planning a year ago.”
The 17-year project will be the largest, longest and most expensive defence acquisition since Federation, potentially costing up to $25 billion. It comes at a time when regional navies such as Indonesia’s, China’s and India’s are seeking to dramatically expand their submarine fleets, potentially altering the balance of naval power in the region.
Defence planners have examined two key studies this year, one by independent think tank the Kokoda Foundation, which have concluded that strategic shifts in the region will make submarines a more important to Australia’s defence than ever before.
Defence will study a wide range of futuristic options for the new submarines, which will be built in Adelaide and will replace the six Collins-class submarines when they are retired in 2025. The new submarines will almost certainly be built by the builder of the Collins-class fleet, the Australian Submarine Corporation, once the government-owned ASC has been privatised.
“South Australia is the only credible location for the construction of Australia’s next generation of submarine,” Mr Fitzgibbon said. The aim will be to create the world’s most deadly conventional submarine fleet to allow Australia to maintain its strategic advantage over fast-growing rival navies in the region.
Although Defence has not yet ruled out the possibility of Australia acquiring nuclear-powered submarines, this option is considered highly unlikely on strategic, practical and political grounds. Instead, defence planners will focus on producing a larger, quieter, faster and more deadly version of the existing six Collins-class submarines, which, after a troubled birth in the 1990s, have proved to be one of the country’s most important defence assets.
Defence has confirmed that one of the options to be considered for the new submarine fleet will be small unmanned mini-subs that can be launched from the “mother” submarines. “Technological developments such as unmanned vehicles would probably offer complementary capabilities to any future underwater warfare platform,” a Defence spokesman said.
These unmanned mini-submarines, crammed with high-tech sensors, could travel remotely tens of kilometres away from the mother vessel to conduct surveillance, detect enemy submarines or carry an SAS team. Another priority for the new submarines will be the new generation air-independent propulsion systems, which allow conventional submarines to stay underwater for longer periods, greatly increasing operational effectiveness.
Defence said the new post-Collins submarines will have more flexible designs, allowing them to be quickly reconfigured for different types of missions, from intelligence gathering to strategic strikes. The new submarines will be able to carry a greater variety of long-range weapons, possibly including long-range cruise missiles as well as short-range tactical land-strike missiles. They will also be configured to facilitate the secret transporting of SAS squads into regional hot spots.
