Key Takeaways:

  • The Stratolaunch Aircraft is a massive plane, 385 feet wide, designed to act as an aerial launch platform for rockets bound for low Earth orbit.
  • With an current weight of 500,000 pounds and a maximum takeoff weight of 1,300,000 pounds, it can carry payloads of up to 550,000 pounds, including multiple Pegasus XL rockets.
  • Launching rockets from high altitude with the Stratolaunch is intended to be a more cost-effective alternative to traditional ground launches.
  • Having recently left its hangar, the aircraft is now set to begin ground and flight-line testing, with its first flight potentially taking place as early as 2019.

What’s 238 feet long, 385 feet wide, 50 feet tall and built to fly? The Stratolaunch Aircraft. The massive plane—designed to act as a launch platform for rockets bound for low Earth orbit—left the hangar where it was built for the first time on Wednesday.

With the scaffolding gone, the company was able to get an accurate weight on the aircraft for the first time. It came in at an incredible 500,000 pounds. Perhaps even more astoundingly, the Stratolaunch is designed for a maximum takeoff weight of 1,300,000 pounds. If everything works out according to plan, it will be capable of carrying payloads of up to around 550,000 pounds.

The aircraft’s first passenger is scheduled to be one of Orbital ATK’s Pegasus XL vehicles. The Stratolaunch has the capacity to carry three of the three-stage, satellite-deploying Pegasus XL rockets at a time. Launching rockets from high altitude is much more cost-effective than ground launches. The Pegasus XL can carry satellites weighing up to 1,000 pounds.

For the Stratolaunch Aircraft, the next step is to begin conducting ground and flight-line testing at Mojave Air and Space Port. If the ground tests go well, the it may take flight as early as 2019. The Stratolaunch Aircraft is a project of Stratolaunch Systems. It was built by Scaled Composites.
