Velontra is building a hypersonic space plane that can takeoff from anywhere in any weather. This horizontal takeoff increases launch reliability and enables customers to directly access any orbit. Our air-breathing propulsion system is up to 6 times more fuel efficient than any rocket, and uses oxygen from the air which creates thousands of pounds of additional payload capacity.
We have millions in current government/commercial contracts and LOI’s.
We have assembled a team of industry experts, government senior executives, and a NASA astronaut.
The hypersonic space plane will work by taking off from any runway with a jet propulsion system. Next, it will climb to over 100,000’ and Mach 5. At this point, it will launch a 2nd stage rocket directly into the desired Low Earth Orbit.
Velontra is “boldly going where no one has gone before.”
