In this video by Spencer Hughes which he published on February 22, 2019, the air demo by the RAAF F-35 at the Melbourne Air Show is highlighted.
According to the Australian Department of Defence:
The F-35A Joint Strike Fighter is the Australian Defence Force’s first fifth-generation air combat capability. It is a highly advanced multi-role, supersonic, stealth fighter which will meet Australia’s requirements to defeat current and emerging threats.
The F-35A is at the forefront of air combat technology. Its advanced sensors and data fusion allows it to gather more information and share it with other Air Force aircraft, Navy ships and Army units quicker than ever before. This will greatly enhance the Australian Defence Force’s situational awareness and combat effectiveness. In addition, to greatly enhanced situational awareness, the F-35A provides its pilots with significantly higher levels of lethality and survivability in combat.
Australia has committed to 72 F-35A aircraft for three operational squadrons at RAAF Base Williamtown and RAAF Base Tindal, and a training squadron at RAAF Base Williamtown.
The first F-35A aircraft was accepted into Australian service in 2018 and the first squadron, Number 3 Squadron, will be operational in 2021. All 72 aircraft are expected to be fully operational by 2023.
In the future, a fourth operational squadron will be considered for RAAF Base Amberley, for a total of 100 F-35A aircraft.
The F-35A is being purchased by the Capability Acquisition and Sustainment Group under project AIR 6000.
