As of 2026, the title of the largest aircraft in the world has returned to the Airbus A380 for active passenger service, while the experimental Stratolaunch "Roc" holds the record for the largest wingspan. Historically, the undisputed king was the Antonov An-225 Mriya, a six-engine monster designed to carry the Buran space shuttle; however, the only completed unit was tragically destroyed in February 2022. The Mriya was 84 meters long with a wingspan of 88.4 meters. In its absence, the Stratolaunch Roc, designed for air-launching rockets, dominates the skies with a massive dual-fuselage design and a wingspan of 117 meters (385 feet)—longer than a football field. For commercial aviation, the Airbus A380-800 remains the largest passenger airliner, capable of carrying up to 853 passengers in a high-density configuration. Meanwhile, the upcoming Boeing 777-9, which is entering wider service in 2026, is the world's largest and longest twin-engine jet, featuring innovative folding wingtips to allow it to fit into standard airport gates despite its massive size.
