The Air Force has designated the GOLauncher1 (GO1) hypersonic flight research vehicle as X-60A. The vehicle is being developed by Generation Orbit Launch Services, Inc., under contract to the Air Force Research Laboratory (AFRL), Aerospace Systems Directorate, High Speed Systems Division.

The research vehicle is an air-dropped liquid rocket, specifically designed for hypersonic flight research to mature technologies, including scramjet propulsion, high-temperature materials and autonomous control. 

“The X-60A is like a flying wind tunnel to capture data that complements our current ground test capability,” said Col. Colin Tucker, Military Deputy, office of the Deputy Assistant Secretary of the Air Force for Science, Technology, and Engineering. “We’ve long needed this type of test vehicle to better understand how materials and other technologies behave while flying at more than 5 times the speed of sound. It enables faster development of both our current hypersonic weapon rapid prototypes and evolving future systems.”

AFRL’s motivation for the X-60A program is to increase the frequency of flight testing while lowering the cost of maturing hypersonic technologies in relevant flight conditions. While hypersonic ground test facilities are vital in technology development, we must also test those technologies with actual hypersonic flight conditions. 

Utilizing new space commercial development, licensing and operations practices, X-60A is envisioned to provide the Air Force, other U.S. Government agencies, and industry with a platform to more rapidly mature technologies.

The X-60A rocket vehicle propulsion system is the Hadley liquid rocket engine, which utilizes liquid oxygen and kerosene propellants. The system is designed to provide affordable and regular access to high dynamic pressure flight conditions between Mach 5 and Mach 8. 

This is the first Air Force Small Business Innovative Research (SBIR) program to receive an experimental “X” designation. The "X" designation on aerospace platforms and rockets indicates use for testing and evaluating new technologies and aerodynamic concepts.
