Firehawk is making a form of chemical rocket engine for space exploration, space commerce, and the U.S. Department of Defense. Unlike liquid fueled rockets, Firehawk uses proprietary engine fuel grains, which are 3D printed from a proprietary polymeric/metal fuel formulation. In addition to being a safer and more economically efficient fuel source, it's exhaust is environmentally benign.
Because of the fuel grain's advanced safety and efficiency, Firehawk's rocket engines require only 10 to 12 parts.
