The Austrian-made Rosenbauer Panther fire truck is the latest advance in aviation fire-fighting technology.

Crew at Williamtown fire station are training on two Panthers and are expected to take delivery of two more in three weeks.

Fire station manager Flight Sergeant Ross Fitzpatrick said the $1.5 million trucks allowed more water or foam to be sprayed on flames more quickly.

"We'll be able to put almost twice the [fire-fighting] agent on the airfield with the same amount of vehicles, which gives us a much better lockdown of the fire if we need to and a better rescue capability," he said.

The Panthers weigh 36 tonnes and can carry 8500 litres of water, 1300 litres of fire-retardant foam concentrate and can produce 7000 litres a minute from its roof and bumper-mounted water hoses.

Corporal David Peachy, who has trained on the Panther, said the new vehicles were far superior to the Trident trucks, which would be phased out of service.

"It allows us to do our job that much better," he said.
