A new era of aeronautical law enforcement has taken off following the arrival of the state of Western Australia's first five-blade Airbus H145 helicopter.

The aviation asset is part of a $54.3million dollar state government funded upgrade to the WA Police Force Air Wing's fleet. The investment includes $7.6 million for operating and maintenance costs, along with the recruitment of two licensed aircraft engineers to be based at Jandakot.

Western Australia is the first law enforcement jurisdiction to operate the new H145 helicopter in the southern hemisphere, giving officers access to the most advanced air support technology available.

An Airbus H145 can be rapidly deployed, allowing it to be airborne within two minutes compared to the 10 minutes it currently takes using other aircraft. This enhanced capability as well as the helicopter's new safety features and reduced maintenance requirements will boost public protection as police respond to emergencies and crime.

A second H145 helicopter is currently under construction in Germany. It's expected to be in Perth and fully operational by March 2024.
