After three years of planning, a missile on wheels designed to top 1,000 mph is finally under construction.

The team behind Bloodhound SSC hope to shatter the current land-speed record of 763.035 mph when it sends Royal Air Force pilot Andy Green streaking across a dry lake bed in South Africa within two years. The team is one of three hoping to exceed 800 mph.

Of the vehicles, the Bloodhound SSC is perhaps the most radical — which is saying something. The car, if it can be called that, features a jet engine and a rocket that produce 47,000 pounds of thrust. To put that in perspective, each of the Concorde’s four engines produced roughly 38,000 pounds at takeoff.
