Airbus has successfully tested a removable firefighting kit on the A400M airlifter during a flight test campaign in Spain.
The test campaign took place in daylight conditions with a minimum operating height of 150ft, flight speeds as low as 232km/h (144 mph) and drops involving up to 20 tonnes of water from the current tank in less than 10 seconds.
The objective of the test campaign is to validate the drop water quantity and time as well as the ability of the A400M to carry out this new role with the kit.
The development of this prototype and the tests have been carried out in partnership with the 43rd Group of the Spanish Air Force, as well as European authorities in Firefighting operations and the Ministry for Ecological Transition and Demographic Challenge (MITECO).
Mike Schoellhorn, CEO of Airbus Defence and Space said, “The development of this firefighting kit is an intrinsic part of our journey towards helping to create a more sustainable and safer world, not only by our actions but also through our products. We strongly believe the A400M can play a vital role in the fight against the ever increasing threat posed by wildfires and support the restoration of social and environmental systems.”
The Airbus firefighting solution created for the A400M is a roll-on / roll-off (RORO) kit that requires no modification to the aircraft and can therefore be used on any aircraft in the A400M fleet.
The water is stored in a fixed tank in the cargo hold, and retained by two independent doors. These doors are connected to two flood pipes, so when the discharge is triggered, the water is expelled through two sections at the end of the ramp.
The introduction of this RORO solution allows a rapid reaction to unforeseen fires and reconfiguration of the aircraft to any of its other roles.

Due to its low level flight capability and maneuverability at low speeds, the A400M can accurately drop payloads of water at very low heights, down to 150ft. In the future, in addition to the development of the production version of this kit, Airbus engineers plan to test the use of the firefighting kit during night time conditions, to further improve its efficiency and effectiveness.
The A400M military transport aircraft is used by seven different countries, with a fleet of 111 in use at the time of writing.
