Bolt
A family of modular solid-fueled rockets X-Bow flies to test hardware at high speed and altitude.
Why it matters
Defense programs need flight tests for hypersonic components and other hardware, and X-Bow reports a multi-year backlog of such tests. Bolt also proves X-Bow's own motors in flight.
How the technology works
Bolt is a family of modular boost rockets built around X-Bow's own solid motors, such as the 32-inch Ballesta. They fly suborbital paths with test payloads aboard.
