Airbus Defense and Space has conducted a new flight-test campaign of the A400M Roll-on/Roll-off firefighting prototype kit, dropping 20,000
liters of retardant and creating high concentration lines over 400 meters long.
Over a period of two weeks, the A400M carried out a ground and flight-test campaign in south-western and central Spain, including six drops,
three of which used red-colored retardant and three using water.
“We have tested a new version of the kit, improving dropping efficiency and reducing discharge time by over 30% compared to last year, while
combined with rapid deployment and easy installation on the A400M aircraft,” said Jean-Brice Dumont, Head of Military Air Systems at Airbus
Defense and Space. “We continue to pioneer new solutions and capabilities for our A400M fleet, in this case protecting populations and
natural environments from fires.”
This roll-on/roll-off kit does not require any modification to the aircraft and, therefore, is interchangeable to any aircraft in the A400M
fleet. The water or retardant is stored in a tank in the cargo hold of the aircraft and, by using a mechanical lever, a door is opened to
allow the liquid to flow out of the aircraft by gravity means through a discharge pipe. The current design of the prototype is capable of
dropping 20,000 liters in a single discharge.
The tanks can be filled in less than 10 minutes using standard high-pressure pumps on ground. The A400M is characterized by its ability to
take off and land on short and unpaved runways, and a wide range of air bases and airfields.
During the campaign, the 43rd Firefighting Squadron of the Spanish Air Force has been involved as technical advisors and assuring that this
capability in the A400M has operational value for any potential operator.
