The Airbus A400M new generation airlifter has successfully conducted a major helicopter air-to-air refueling certification campaign, completing the majority of its development and certification objectives. Airbus Defence and Space aims to achieve full helicopter air-to-air refuelling certification later this year with the conclusion of all mandatory night operation trials. 

The flight tests, performed in coordination with the French Armament General Directorate (DGA), involved operations with two French Air Force H225M helicopters. The campaign took place in day and night conditions over the west coast of France at between 1,000 ft and 10,000 ft and flight speeds as low as 105 knots. During those flights, a total of 81 wet contacts and transfers of 6.5 tons of fuel were achieved, which included simultaneous refueling of two helicopters for the first time. The tests confirmed the positive results of the dry and wet contact operations conducted in 2019 and 2020. 

Helicopter air-to-air refueling is a unique military capability and key for Special Forces operations, involving aircraft with different flight profiles and sharing a very limited common flight envelope, requiring close formation flying patterns at low altitudes and night time conditions.
