Australia's defence force has shown off some of its new $3 billion military muscle.
Army officials presented a number of the freshly delivered Black Hawk helicopters at the Holsworthy Barracks in Sydney on Tuesday.
For the sizeable sum, Australia has ordered 40 of the American-made aircraft with a dozen to be operational by the end of 2024.
At the military base on Tuesday, officials showed just how effective the choppers will be with a series of impressive mock warfare scenarios.
Special forces performed a demonstration raid on an overseas embassy, along with a mock hostage extraction.
Flexing the new birds' rapid flight time, lucky passengers zoomed over Sydney Harbour and up to the city's northern beaches, before returning to the southwest military base.
Major General Jeremy King said the vehicles are important in increasing Australia's military capabilities.
"We have a really impressive capability (here)," Maj Gen King said.
"(It) is going to set us up for success in relation to challenges of modern warfare."
The Black Hawks replace Australia's Taipan fleet, which was retired in the wake of a fatal crash in Queensland where four army personnel were killed.
The quartet were taking part in military exercises off the north Queensland coast when their helicopter hit the water off Hamilton Island.
