The aircraft will be used throughout the bushfire season by Forest Fire Management Victoria, Country Fire Authority and Fire Rescue Victoria to respond to fires.
FFMVic deputy chief fire officer Aaron Kennedy said aircraft play a critical role when responding to fires.
“On high fire danger days, as soon as the call goes out to respond, firebombing aircraft will be dispatched so we can hit the fire hard and fast in the initial stages and keep fires small,” Mr Kennedy said.
“North-east Victoria is one of the most fire-prone areas in the world and this impressive aircraft fleet will work together to deliver an effective fire suppression operation.”
CFA acting assistant chief fire officer Hume region Colin Brown said the aircraft would support on-ground firefighters to contain fires both on private property and public land.
“Dispatching the aircraft with ground crews, fire trucks and bulldozers increases our ability to rapidly contain or limit the size and spread of fires,” Mr Brown said.
“The flow-on effect of this is a reduced impact on local communities and the environment.
“It also reduces the length of time firefighters are required to work in an extremely hazardous environment.”
