NATO Tanker Fleet Grows to 10 Aircraft
The Multinational MRTT Fleet, operated from Eindhoven and Cologne, is set to reach 12 aircraft as more countries join the programme.
Updated on Nov. 2, 2026 in Military
As of a NATO fleet update published on 15 September 2026, the pooled Airbus A330 MRTT fleet has grown to 10 aircraft. Finland joined as the ninth participating country, and the fleet is planned to reach 12 aircraft.
Why it matters
The pooled fleet gives participating countries shared aerial refueling capacity funded collectively rather than through separate national tanker forces. Denmark and Sweden's accession funded two further airframes, expanding the shared capability.
NATO's 15 September 2026 fleet update reports 10 aircraft on strength, with nine participating countries and two further tankers due in mid-2028 and early 2029. The extraction does not detail the funding allocation per aircraft beyond the airframes funded by Denmark and Sweden.
The players
NATO Support and Procurement Agency
The NATO agency that manages the Multinational MRTT Fleet and its procurement on behalf of participating allies.
NATO
The North Atlantic Treaty Organization, which owns the Multinational MRTT Fleet aircraft and publishes its fleet updates.
The details
The Multinational MRTT Fleet is owned by NATO and managed by the NATO Support and Procurement Agency, with aircraft operated by the MMU at Eindhoven Airport in the Netherlands and a forward operating base at Cologne, Germany. Participating countries fund the fleet and receive annual flight-hour allocations.
Timeline
June 2020: The first MMU aircraft, T-055, was delivered.
7 July: Finland's accession as the ninth participating country was announced.
15 September 2026: NATO published its fleet strength update.
Mid-2028: The first of two further tankers is due.
Early 2029: The second of two further tankers is due.
Season Trajectory
The Multinational MRTT Fleet began with its first delivery in June 2020 and has since grown to 10 aircraft through successive country accessions. Its planned expansion to 12 aircraft and a third operating base at Karup, Denmark extends that pooled-funding model across more of the alliance.
Participating countries share the fleet's cost and receive annual flight-hour allocations rather than maintaining separate national tanker forces. The pooled arrangement determines how much aerial refueling capacity each member can draw on for its own operations.
The takeaway
Shared funding lets smaller allies gain access to aerial refueling capacity they might not sustain alone, and the fleet's growth from one aircraft in 2020 to ten today shows how pooling can scale over time.
What happens next
Two further tankers are due in mid-2028 and early 2029, and NATO plans to open a third operating location at Karup, Denmark.
