How to Compare Military Transport Aircraft: Range, Payload and Short-Field Performance

A useful comparison of military transports starts with the mission: cargo weight and size, route, runway surface and whether the constraint is takeoff or landing.

There is no single transport aircraft that leads in range, payload and short-field performance under every condition. Compare aircraft against the same mission: a specific cargo weight and size, route, runway and operating environment. A maximum-payload figure, an empty-aircraft range figure and a short-runway claim describe different things—not one comparable performance result.

Start with the mission, not the headline specifications

Before comparing aircraft, write down the operation each one would need to perform. At minimum, specify:

  • Cargo: weight, dimensions, shape, floor-loading needs and loading method.
  • Route: distance, required reserves, destination holding time and whether refueling is available.
  • Airfield: runway length and width, pavement or soil condition, field elevation, temperature and obstacles.
  • Performance measure: whether the constraint is takeoff distance, landing distance, or both.
  • Mission role: tactical delivery to austere locations, strategic movement between established bases, or a combination.

Then compare each aircraft at a stated cargo weight and route. Published figures often use different payloads, runway metrics and environmental assumptions, so a direct ranking is justified only when those conditions are sufficiently aligned.

How to read range and payload figures

Range is meaningful only when its associated load and mission assumptions are clear. Ferry range—an aircraft’s range with no payload—is not a measure of how far it can carry a useful load. Maximum payload, meanwhile, does not show how far that load can travel.

The C-17 illustrates the difference. Boeing states a range of more than 6,200 nautical miles with no payload. The U.S. Air Force Air Mobility Command (AMC) lists approximately 2,400 nautical miles with a 164,900 lb payload, at an initial cruise altitude of 28,000 ft. Those are separate load cases, not conflicting estimates of the same flight. AMC gives the C-17’s maximum payload as 170,900 lb.

Other published figures also pair a range with a particular load. Lockheed Martin’s October 2024 C-130J Fast Facts lists the C-130J-30 at 2,160 nautical miles with a 40,000 lb payload and maximum payload of 46,700 lb. Airbus states that the A400M can carry 20 tonnes to 3,400 nautical miles, alongside a 37-tonne maximum payload. Embraer lists the C-390 at 26 tonnes to 1,080 nautical miles and 23 tonnes to 1,470 nautical miles.

These points are useful for understanding each aircraft’s published capability, but they do not create a perfectly matched comparison. For example, the A400M and C-390 figures use metric tonnes, while the C-130J-30 and C-17 figures use pounds; the payloads and stated assumptions differ. Do not treat any of them as a guarantee of operational range for a particular flight.

Compare the cargo the aircraft can actually accommodate

Weight is only one part of cargo fit. A load may be below an aircraft’s payload limit but still be too long, wide, tall or difficult to load. Cargo-hold dimensions and volume, door and ramp openings, floor limits and loading access all affect whether a particular item can travel.

For the A400M, OCCAR lists a 340 m³ cargo hold, while Airbus describes a 4 m by 4 m cargo cross-section. These measurements help characterize the space, but they do not by themselves establish that any particular load will fit or can be handled. For a real movement, verify the aircraft’s loading limits and the cargo’s dimensions, floor contact and loading requirements.

Compare short-field claims carefully

“Short field” is not a universal runway number. Takeoff distance and landing distance are different measures, and published distances may assume different aircraft weights, runway surfaces, weather and obstacle-clearance conventions. A capability to operate on an unpaved strip is not equivalent to a stated distance on a paved runway.

For context, AMC says the C-17 can take off and land on runways as short as 3,500 ft and 90 ft wide. The statement does not say that every payload can use a runway of that size. Lockheed Martin lists a 3,000 ft landing distance for the C-130J-30 at 135,000 lb. That is a landing figure at a specified aircraft weight, not a takeoff distance or a directly comparable C-17 test.

Embraer’s KC-390 brochure lists takeoff distance of 1,524 m for a 500-nautical-mile mission with a 23-tonne payload, at sea level under ISA conditions. It separately lists a 1,000 m normal landing distance at sea level/ISA with 26 tonnes. The distinction matters: these are different phases of flight and different load cases, and neither should be ranked directly against another aircraft’s landing figure.

Embraer also describes a separate C-390 field case: normal operation from a 4,000 ft semi-prepared soft airstrip while carrying 12 metric tonnes for 500 nautical miles, subject to stated soil and CBR conditions. That is useful evidence that runway surface and load belong in the comparison, but it is not the same performance point as the brochure’s sea-level/ISA runway distances.

What the published figures say about each aircraft

Aircraft Published payload and range examples Runway or cargo-access evidence
C-130J / C-130J-30 Lockheed Martin’s October 2024 Fast Facts lists the standard C-130J at 47,000 lb maximum payload and 1,980 nautical miles at 40,000 lb payload. The C-130J-30 is listed at 46,700 lb maximum payload and 2,160 nautical miles at 40,000 lb payload. The payload figures assume wing-relieving fuel. Landing distance: 3,200 ft at 135,000 lb for the standard C-130J; 3,000 ft at 135,000 lb for the C-130J-30. AMC describes the C-130 family as a tactical transport able to use rough, unimproved landing zones.
A400M Atlas Airbus states 20 tonnes to 3,400 nautical miles and a 37-tonne maximum payload. OCCAR lists maximum take-off weight of 141,000 kg and a 340 m³ cargo hold. Airbus and OCCAR describe tactical delivery to short, soft or unpaved airstrips. The cited Airbus material does not provide a runway-distance figure under conditions directly comparable to the C-130J or KC-390 figures.
C-17 Globemaster III AMC lists 170,900 lb maximum payload and approximately 2,400 nautical miles unrefueled with 164,900 lb payload, at an initial cruise altitude of 28,000 ft. Boeing states more than 6,200 nautical miles with no payload. AMC states runway capability as short as 3,500 ft by 90 ft; Boeing describes short paved and unpaved strip operations. Neither statement means that every payload can use the shortest runway.
C-390 Millennium / KC-390 Embraer lists 26 tonnes to 1,080 nautical miles and 23 tonnes to 1,470 nautical miles. These are separate payload-range examples. Brochure distances include 1,524 m takeoff for a 500-nautical-mile mission at sea level/ISA with 23 tonnes, and 1,000 m normal landing at sea level/ISA with 26 tonnes. A separate semi-prepared-strip case is 4,000 ft, 12 tonnes and 500 nautical miles, with soil/CBR conditions specified.

How the aircraft roles affect the comparison

C-130J: tactical access and variant-specific figures

AMC describes the C-130 as a tactical transport whose straight-wing, four-engine turboprop design supports low stall speed and short takeoff and landing performance. It can operate in rough, unimproved landing zones. Those role and design descriptions do not guarantee a particular runway distance in every condition. Keep the standard C-130J and stretched C-130J-30 figures separate: their listed payload, range and landing-distance values differ.

A400M: tactical delivery with strategic reach

The A400M’s published examples combine a 20-tonne load with 3,400 nautical miles of range, and describe tactical delivery to short, soft or unpaved strips. Airbus characterizes it as combining strategic-distance transport with access to tactical short and unpaved airstrips. That is the manufacturer’s description; without a comparable runway-distance figure, it does not support a precise short-field ranking against the other aircraft.

C-17: heavy loads and austere-field operations

The C-17’s published maximum payload is substantially larger than the listed C-130J-family and C-390 payload figures, and its AMC loaded-range example pairs 164,900 lb with approximately 2,400 nautical miles. Boeing and AMC also describe short-field or austere-strip operations. The runway statement and loaded-range statement are separate capabilities; do not infer that the maximum payload can be carried on every short or unpaved runway.

C-390: a medium-airlift comparison point

The C-390’s published payload-range points and its semi-prepared-strip example show why the mission conditions need to travel with every figure. Its 4,000 ft strip case uses 12 tonnes and a 500-nautical-mile distance, not the 23- or 26-tonne payloads in the brochure’s separate runway or range examples.

A practical comparison checklist

  1. Set the load. Use the same cargo weight for each aircraft where published data permit, and check dimensions and handling needs separately.
  2. Set the route. Compare loaded range at that weight, not empty-aircraft range. Record the source’s reserve, holding and cruise assumptions when available.
  3. Set the airfield case. Record runway length and width, surface, elevation, temperature and obstacles, along with aircraft weight or payload.
  4. Separate takeoff from landing. Do not rank one aircraft’s takeoff distance against another’s landing distance.
  5. Check the mission role and support needs. Determine whether the operation is tactical or strategic, whether the field is austere, and whether refueling, airdrop or a passenger configuration changes the case.
  6. Label unmatched figures. If conditions or payloads differ, present the numbers as separate examples rather than as a controlled contest.

Comparison assumptions can materially change the result. A 2016 National Defense University Press payload-range chart, for example, states assumptions of no wind, a standard day, step climb and one hour of holding fuel at the destination. Its author says the data came from official, manufacturer and other open sources. It is useful methodological context, but its date means it should not replace current aircraft-specific figures.

Which aircraft carries the most the farthest to a short runway?

The answer depends on the cargo and field case. The C-17 has the largest maximum payload among the figures presented here, but its no-payload range is not its range at maximum payload, and its runway statement is not tied to every load. The A400M has a stated 20-tonne range point and descriptive short-strip capability, but the cited material does not give a directly comparable runway distance. The C-130J family is explicitly described by AMC as able to use rough, unimproved landing zones, while its published range and landing figures distinguish variant and weight. The C-390 has useful loaded-range and field examples, but those examples use different payloads and conditions.

For a defensible choice, match the aircraft to a specific cargo, route and runway case, then seek performance data for that same case. The published figures support a comparison of roles and selected capabilities; they do not establish one winner across range, payload and short-field performance.
