The SA hypersonic vehicle will use advanced state-of-the-art materials, such as titanium and inconel honeycomb panels, which cost less and weigh 23% less than alternative structures, resist ice build up, and can withstand reentry temperatures. These features significantly improve vehicle safety, durability, and reliability. Similar materials were used on the X-15 experimental aircraft, which flew a comparable flight path to the SA reusable launch vehicle. The robustness of the structure allows the vehicle to be reusable, just like a normal airplane, dramatically reducing the cost per flight.

The vehicle's structure also serves as the cryogenic fuel tank, eliminating the need for extra tank material, saving weight and cost. The tanks are lined with high efficiency, multi-layer insulation that minimizes propellant boil-off and prevents external frost formation, thus eliminating the hazards associated with ice damaging the vehicle. Between flights the tanks can be readily refueled with clean-burning cryogenic hydrogen produced using our sustainable energy generation processes.
