Australia's third and final air warfare destroyer, the Sydney, is set to be launched in Adelaide, as the $9 billion program to significantly bolster the nation's defence capability nears an end.
The Sydney will be lowered into the water in Adelaide on Saturday as work continues to complete its fit-out ahead of sea trials.
Like its sister ships, the HMAS Hobart and the Brisbane, the Sydney is 146 metres long with a range of about 5000 nautical miles, or about 9000 kilometres, and a top speed of more than 28 knots.
It will have a crew of 186 and is powered by a combination of gas and diesel turbines driving twin propellers.
The destroyers are armed with harpoon missile systems and have missile decoy technology.
They are also fitted with a flight deck and hangar for one helicopter.
The HMAS Hobart was launched in Adelaide in 2015 and commissioned in September last year.
The Brisbane was launched in 2016 and is expected to be commissioned later this year, while the Sydney is scheduled to come into full service in late 2019.
The launch of the Sydney comes as shipbuilding jobs continue to be shed in Adelaide with the wind down of the destroyer program.
The program was also plagued with problems in its early years, with delays and cost blowouts but was recently removed from the defence department's projects-of-concern list.
The federal government has moved to bolster the defence shipbuilding sector in South Australia with a decision to produce some offshore patrol boats at Osborne, along with the navy's next fleet of frigates and future submarines, providing for decades of continuous work supporting thousands of jobs.
