Stratolaunch (Seattle, WA, US), the company behind the world’s largest all-composites aircraft, has reportedly backed off of its development program of a family of launch vehicles that were intended to use the company’s carrier aircraft as a mobile launch platform. 

The company says, “we are streamlining operations, focusing on the aircraft and our ability to support a demonstration launch of the Northrop Grumman [Falls Church, VA, US] Pegasus XL air-launch vehicle.”

According to Aerospace Daily & Defense Report, the end of the launcher program comes just weeks after tests of its PGA rocket engine’s preburner at NASA Stennis Space Center (Hancock County, MS, US) – and three months after Stratolaunch founder Paul Allen, passed away from complications of lymphoma.  

The family of launchers was planned around two expendable modular rockets powered by the PGA engine: a medium launch vehicle (MLV) with a 3,400 kg payload capacity and a medium launch vehicle-heavy with a 6,000 kg payload capacity. A medium-class payload reusable space plane was also part of the program. 


  • Thermoplastic composites: Primary structure?

    Yes, advanced forms are in development, but has the technology progressed enough to make the business case?

  • Advanced materials for aircraft interiors

    Applications aren't as demanding as airframe composites, but requirements are still exacting — passenger safety is key.

  • Fabrication methods

    There are numerous methods for fabricating composite components. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application. Here's a guide to selection.
