The World's Largest Air Forces By Number Of Transport Aircraft

The world's largest air forces by transport aircraft are examined, with the United States Air Force dominating the transport fleets through heavy lifters like the C-5M and C-17, and tankers that often double as transports such to situate its capacity at the top. Russia has far fewer tanker aircraft, and its transport fleet appears smaller than inventories suggest, while private contractors and civilian-operated aircraft also contribute to the picture. Direct comparisons are constrained by undisclosed inventories, misaligned classifications, and the use of civilian or privatized assets in some countries. Notably, the UK’s Voyager tankers are privately owned by AirTanker Holdings, illustrating transfer of critical capability to private operators. The analysis cautions that many fleets rely on unmodified civilian airframes for military airlift, complicating apples-to-apples ranking.
