The Stratolaunch Roc, the largest aircraft ever built by wingspan at 385 feet, is reviving air-launch hypersonic testing with its reusable Talon A vehicle.
Stratolaunch is adding a Boeing 777 to its carrier fleet, expanding hypersonic test capacity by 35% as U.S. defense programs compete for flight-test infrastructure.
The Roc - the world's largest aircraft by wingspan at 385 feet - is now America's mobile hypersonic test platform for critical Department of Defense programs.
