New South Wales has signed a contract with United States-based Coulson Aviation to purchase three aircraft for firebombing duties, including a modified Boeing 737 large air tanker.

In addition to the modified 737, the contract announced by NSW Minister for Police and Emergency Services David Elliott on Wednesday also included two Citation V lead/intelligence aircraft.

The Minister’s statement noted the modified 737 would give the state year-round access to a large air tanker, given an increasing number of winter bushfires in recent times.

“Last fire season there were more fires during winter than across the summer months,” Elliott said.

“The NSW Government is committed to ensuring our firefighters have the tools they need year round to help protect lives and property.”


Coulson Aviation said in a statement the 737 Fireliner, which was certified by the United States Federal Aviation Administration (FAA) in as an air tanker and passenger transport in 2018, was the largest ever air tanker ever purchased by a country.

The aircraft can carry 15,150 litres of fluid while carrying 72 passengers.

“When we started the B737 Fireliner program we set out to create a new generation of air tanker,” Coulson vice president of aviation Britton Coulson said in a statement.

“The goal was to utilize the latest SMART technology in our tanking system and create a multi-use firefighting aircraft that would create the best value for our customers.”

Coulson Aviation said it would provide all flight and maintenance personnel for the three aircraft under a 10-year operational contract.

“With this contract now in place, Coulson Aviation PTY will establish a year-round operation in NSW to support its contracts at the RAAF base in Richmond where the B737 Fireliner will be pre-positioned to support the RFS this coming July.”

The company supported the NSW Rural Fire Service with its 737 Fireliner during the 2018/19 summer fire season. It ha also operated a C-130 Hercules for firefighting duties in Australia in previous years.

NSW Rural Fire Service acting commissioner Rob Rogers said the 737 ended up being the preferred option following a review of the large and very large air tankers that had been deployed over previous fire seasons.

“This type of aircraft provides us with a fast, effective and flexible option for fighting fires year-round, and supporting firefighters on the ground,” Rogers said.

    Why would there ever be a need for 72 passengers to be onboard whilst the aircraft is carrying ant-fire liquids?

      Moving fire-fighters to the fire ground. However, that requires a runway long enough within cooee to actually be of much use.

      Only need when they first respond and they can transport personnel to establish a forward base, and firefighting staff, then do a fire run. They would not carry passengers while doing the fire attacks as it is unnecessary and dangerous to the passengers.

    Ferry fire personnel option

    Maybe Adventure Tourism REEVES35?

    The 72 passengers would probably be RFS crew that can de deployed on the ground…..

    Average payload of 737 is 20,000kgs less 15150 kgs for fire fighting fluid.
    Leaves 4850kgs for 72 pax +gear (67.5 kgs per pax)
    Definitely one or the other but not both.

      I spent a bit of time with the crew whilst they were out and I seem to recall that 72 pax and and the 15 tonne retardant wasn’t a problem. (It was still waiting on cert for pax whilst in oz on it’s first tour) It is also unique in that it can be pressurised when enroute and during drop runs. The other acft (C130, DC10 or MD11???) were limited to O2 levels when carrying retardant for runs.
      Moving firefighting crew around is a big issue for the RFS and allows this acft to be used after dark when fire drops not (yet) possible.
      Interestingly the crew were quite low time on the B737 but were very experienced fire bombers. Endorsing on type was regarded as simple as compared to teaching the complexities operations of fire bombing.
      It is a beautifully engineered acft and Coulson will be churning these out for years.

    In NSW how many rural airports can accommodate this type of aircraft ,and supply the quantities of water needed?

    What a beautiful aircraft. Excellent news regarding the purchase by NSW Government. Used on 10 September 2019 for the peregian Beach fires on the Sunshine Coast ( QLD).

    I would have thought the Bombardier CL-415 or CL-515 by Viking would have been a better solution as, even though they carry less, the turn around time is much less and the transit time savings between drops could be significant.

    This is one of 3 solutions
