The Scaled Composites Model 351 Stratolaunch, nicknamed Roc, is a one-off twin-fuselage testbed aircraft built by Scaled Composites for Stratolaunch Systems to carry air-launch-to-orbit rockets. It was announced in December 2011, rolled out in May 2017 and first flew on 13 April 2019, staying aloft for 149 minutes before landing at Mojave. Its wingspan of 385 feet (117 metres) is the longest of any aircraft that has flown, surpassing the Hughes H-4 Hercules. It has two fuselages 238 feet long, six Pratt and Whitney turbofan engines and a maximum take-off weight of 1,300,000 pounds, and was meant to carry a payload of 550,000 pounds. After its owner company ceased operations in 2019 and was bought by Cerberus Capital Management, the aircraft was repurposed to offer air-launched hypersonic flight testing.
