C-130 vs C-17: Size, Payload, Speed and Cost, and Why the Older Plane Is Still in Production

How we compare the C-130 and the C-17

The C-130 Hercules has been built in many models since the 1950s. This page compares the one still in production, the C-130J Super Hercules, with the C-17A Globemaster III, and notes where the stretched C-130J-30 or the older C-130H changes the answer.

We judge them on what readers search for: size, payload, speed and range, the runways they can use, and cost. Full specifications sit on our C-130J Super Hercules and C-17 Globemaster III pages.

C-130 vs C-17 size comparison: which is bigger?

The C-17 is much bigger. It is 174 feet (53 m) long against 97 feet 9 inches (29.8 m) for a standard C-130J, a difference of about 76 feet (23 m).

Its wing spans 169 feet 10 inches (51.8 m), about 37 feet (11.4 m) more than the Hercules’ 132 feet 7 inches (40.4 m). Its tail stands 55 feet 1 inch (16.8 m) high, some 16 feet (5 m) above the C-130J’s.

The stretched C-130J-30 closes part of the gap. Its fuselage is 15 feet longer, at 112 feet 9 inches (34.4 m), and that is the length the database panel above shows.

The cargo holds show the real difference. A standard C-130J’s hold is 41 feet (12.5 m) long, 10 feet 3 inches (3.1 m) wide and 9 feet (2.7 m) high, or 56 feet (16.9 m) long on the J-30.

The C-17’s hold is 88 feet (26.8 m) long, 18 feet (5.5 m) wide and 12 feet 4 inches (3.8 m) high. That is more than twice the length of a standard C-130J hold and about three-quarters wider.

Payload: the C-17 carries about four times as much

The C-17’s maximum payload is 170,900 pounds (77,519 kg). The Air Force gives the C-130J a maximum allowable payload of 42,000 pounds (19,050 kg), so the Globemaster lifts about four times as much.

Hercules payload figures vary with the source. The Air Force rates the C-130J-30 at 44,000 pounds (19,960 kg), while Lockheed quotes up to 46,700 pounds (21,180 kg) for it, a figure that assumes fuel carried in the wings to relieve structural load.

The gap decides what each one can carry. The C-17 takes a 69-ton M1 Abrams main battle tank, or 18 pallets of cargo.

A C-130 cannot come close to a tank. Its hold takes six pallets, or eight on the J-30, and the Air Force lists its largest loads as utility helicopters and six-wheeled armored vehicles.

For people, a standard C-130J seats 90 combat troops or 64 paratroopers, and the J-30 seats 128 troops or 92 paratroopers. The C-17 is designed to airdrop 102 paratroopers with their equipment.

Which is faster, and which flies farther?

The C-17 is faster, by about 100 mph. The Air Force gives it a cruise speed of about 450 knots (518 mph, 833 km/h), or Mach 0.74, at 28,000 feet.

The C-130J cruises at 362 knots (417 mph, 670 km/h), or Mach 0.59, at 22,000 feet, and Lockheed quotes a maximum cruise speed of 365 knots. The stretched J-30 is slightly slower, at 356 knots (410 mph).

The J model is still far quicker than the Hercules before it. Compared with the C-130H, it has 40 percent more range, a 21 percent higher maximum speed and a 41 percent shorter takeoff distance.

The C-17 also flies higher. Its service ceiling is 45,000 feet, while the C-130J’s is 28,000 feet with a full 42,000-pound load.

Range with a load

Range depends on the load, so compare like with like. With 164,900 pounds (74,800 kg) aboard, a C-17 flies about 2,400 nautical miles (2,760 miles) without refueling.

A C-130J carrying 34,000 pounds (15,420 kg), its maximum normal payload, flies 1,800 nautical miles (2,071 miles). With 35,000 pounds aboard, the stretched J-30 reaches 2,100 nautical miles (2,417 miles).

Put simply, the C-17 carries nearly five times the load about a third farther. It can also refuel in flight, which is why the Air Force lists its range simply as global.

Where the C-130 wins

Rough strips and short runways

The Hercules was built for the tactical end of airlift. The Air Force says it primarily performs the tactical part of the airlift mission, operating from rough, dirt strips on high-flotation landing gear.

It also calls the C-130 its prime transport for airdropping troops and equipment into hostile areas. Lockheed quotes a landing distance of 3,000 feet (914 m) for a C-130J-30 at 135,000 pounds (61,235 kg).

The C-17’s short-field figure is 3,500 feet (1,067 m). That is remarkable for an aircraft its size, but it is still the longer of the two.

The full story of those trials, and the smaller plane the Navy chose instead, is in our piece on the C-130’s aircraft carrier landings.

Less than half the cost per flight hour

The Pentagon’s fiscal 2026 reimbursement rates put a C-130J at $9,980 per flight hour and a C-17A at $23,895. That makes the Hercules less than half as expensive to fly.

Per ton of cargo, the arithmetic flips. Dividing each hourly rate by maximum payload gives about $280 per ton for a C-17 against about $475 for a C-130J, so a full C-17 is the cheaper way to move heavy cargo.

The J model is also far cheaper to run than the Hercules it replaced: the same rates list an old C-130H at $17,650 per hour. The Air Force says the J cuts manpower and operating costs, and it flies with three crew instead of the C-130H’s five, dropping the navigator and flight engineer.

Numbers, and a production line that never closed

The C-130 is the longest continuously produced military aircraft, having reached 70 years of production in 2024. More than 2,700 of all models had been built by June 2024.

Lockheed counted more than 570 C-130Js delivered to 27 countries as of September 2026, flying 20 mission sets from aerial refueling to firefighting. Only 279 C-17s were ever built.

Where the C-17 wins

Outsize cargo, straight to the front

The C-17 carries loads no C-130 can. Its aft ramp and door take virtually all of the Army’s air-transportable equipment, the Air Force says, from a 69-ton M1 Abrams tank to trucks and trailers.

It was also built to land that cargo close to the fight. The Air Force says it can deliver troops and cargo directly to forward bases, and fly tactical airlift and airdrop missions as well.

A high-lift wing, slats and externally blown flaps let it use runways as short as 3,500 feet and as narrow as 90 feet (27.4 m). On a runway that narrow, it turns around with a three-point star turn, using its thrust reversers to back up.

Jet speed and global reach

Four Pratt & Whitney F117 turbofans, based on the PW2040 that powers the Boeing 757, give the C-17 its jet speed and 45,000-foot ceiling. The C-130J flies on four Rolls-Royce AE 2100D3 turboprops turning six-bladed composite propellers.

That is what makes the C-17 the strategic half of the pair. It can carry a heavy load between continents, refueling in flight if needed, and then land it at a small, austere airfield.

Why was the C-17 discontinued?

Because the orders ran out. In 2009 Defense Secretary Robert Gates said no more C-17s would be ordered beyond the 205 then planned.

Additional aircraft took the Air Force fleet to a final 223. When international orders dried up too, Boeing completed the last C-17 at Long Beach, California, in November 2015 and closed the plant.

Now there is talk of reopening it. In June 2026 the House Armed Services Committee told the Air Force to brief it by March 1, 2027, on whether C-17 production could restart, and Boeing said it was encouraged by the discussions.

No restart had been decided as of September 2026. According to The War Zone, no other aircraft in the C-17’s class is in production anywhere in the West.

Airbus pitches its turboprop A400M as the aircraft in between, and we set it against the Hercules in our C-130 vs A400M comparison.

The Air Force plans to fly its C-17s until 2075. The Next-Generation Airlifter, due to start fielding around 2038, is planned to replace the C-5 and the C-17; for how those two compare, see our C-5 Galaxy vs C-17 comparison.

The C-130J in 2026: production running, deliveries paused

The Hercules has its own problem this year. In February 2026 the Air Force paused C-130J deliveries after a technical issue turned up while integrating a new communications suite, which had been added because older components were obsolete.

Production never stopped, Lockheed said, and it projected 16 to 24 deliveries in 2026. Aviation Week reported that only two C-130Js were delivered in 2025, a figure Lockheed did not confirm.

We found no public confirmation that US deliveries had resumed as of mid-September 2026.

C-130 vs C-17 crashes and safety record

The C-17 has one hull loss in 35 years of flying. On July 28, 2010, a C-17 crashed at Elmendorf Air Force Base, Alaska, while practicing for an air show, killing all four people aboard.

Pilot error caused a stall. It remains the type’s only fatal crash.

The C-130J has had three fatal crashes. A Norwegian C-130J-30 hit Kebnekaise mountain in Sweden in March 2012, killing five, and an Indian Air Force C-130J-30 stalled in wake turbulence near Gwalior in March 2014, killing five.

In October 2015 a US Air Force C-130J crashed at Jalalabad, Afghanistan, after a night-vision goggle case jammed the control yoke. Eleven people aboard and three on the ground were killed.

Raw counts are uneven, though. More than 2,700 C-130s of all models have been built since the 1950s, against 279 C-17s, and many older Hercules are still flying worldwide.

On March 23, 2026, a Colombian Air Force C-130H built in 1984 crashed shortly after takeoff at Puerto Leguízamo, killing 69 of the 126 people aboard. Investigators examined mechanical failure, pilot error and excess weight as possible causes.

The verdict

The C-17 is the bigger, faster and more capable airlifter. It carries about four times the C-130J’s payload, including an M1 Abrams tank, cruises about 100 mph faster, and flies a heavy load much farther.

The C-130J is the better tactical tool and the cheaper one to fly, at less than half the C-17’s hourly rate. It is built for rough, dirt strips, and more than 570 have been delivered to 27 countries.

The US Air Force flies both: the C-17 to carry a force across oceans, the C-130 for the tactical legs once it arrives. For where they sit in the wider field, see our guides to the largest cargo planes and the types of cargo planes.
