Firehawk Aerospace custom designs and builds hybrid rocket engines. The most expensive and time-consuming part of designing a new space vehicle is developing the engine. A new rocket engine costs hundreds of millions of dollars, it also takes up to 5-7 years to design, and requires hundreds, if not thousands of parts. Yet they are still prone to failure. Firehawk has built a hybrid rocket engine that has only 12 parts, cannot accidentally detonate, and it can be designed in 4 months.
