Green Arrow

X-Prize suborbital ballistic spacecraft concept of Flight Exploration of London, England.

The Green Arrow was a design of Flight Exploration of London, England, designed by a team led by Dr Graham Dorrington. The vehicle was based on the hydrogen peroxide rocket engine technology successfully developed in the UK during the 1950's and 1960's, then abandoned by the government. Green Arrow used conventional rocket powered vertical takeoff and parachute landing. The prototype vehicle was to have an all up mass of 20,000 kg at takeoff and a lightweight composite structure permitting a mass ratio of 0.3.
