Not counting the plane what is the largest or heaviest payload ever flown?

The Antonov-225 currently holds a number of records...

  • Heaviest maximum take-off weight at 710 tons (1.4 million pounds)
  • Total air lifted payload of 558,590 pounds
  • Single item payload of 418,830 pounds
  • Longest wingspan of 290 feet for any aircraft in service (Stratolaunch and H-4 Hercules had larger wingspans, but neither are currently in service)

The A380 by comparison has a maximum take-off weight of around 1.2 million pounds (600 tons) and is 260 feet wide.

For helicopters, the heaviest payload holder currently goes to the Mil Mi-26

It has the world record for a payload lifted to 2000 meters (about 6500 feet) of 125,153 pounds (about 62 tons).


As for the "largest" I'm not sure you can separate that. The Antonov 225 holds the largest single item payload referenced above, so that is held by weight. If you are asking about physical size, that could mean a number of things. Longest, widest, tallest, etc.

The Airbus Beluga held the world record for the most "voluminous" cargo ever lifted when it transported a chemical tank for a marine vessel.

    $\begingroup$ You’re missing the space shuttle carrier. Probably more voluminous than the beluga’s cargo $\endgroup$ – Antzi Jun 5 at 4:27
  • $\begingroup$ @Antzi It may be close, by volume the shuttle may be a little bigger, but it is hard to calculate due to its irregular shape. It could also be argued that the Antonov 225 also holds that record, but you'd have to compare the volume of the STS to the Buran. The STS is heavier, but the two shuttles are very similar in size. $\endgroup$ – Ron Beyer Jun 5 at 14:02
  • $\begingroup$ en.m.wikipedia.org/wiki/Stratolaunch_Systems has a longer wingspan $\endgroup$ – Muze the good Troll. Jun 5 at 18:03

    $\begingroup$ @Muze True, it was only recently that it flew, and it may never fly again since the company is now defunct and looking for buyers for its assets. The Stratolaunch was a very specialized vehicle and will probably be scrapped for parts. The H-4 Hercules also had a wider wingspan, but never really "flew". $\endgroup$ – Ron Beyer Jun 5 at 18:08
