HyImpulse is a German private space launch enterprise headquartered in Neuenstadt am Kocher and developing a small launch vehicle designed around hybrid-propellant rockets. The company is a DLR spinoff founded in 2018 out of the chemical propulsion center of the German space agency's Lampoldshausen facility.[1] HyImpulse is bankrolled by Rudolf Schwarz, chairman of German technology company IABG.[2]

The company is developing a three-stage hybrid rocket designed to transport to LEO satellites of up to 500 kg named SL1.[3] The company is also developing the suborbital SR75 launch vehicle. This smaller rocket will serve both as the company's first commercial service and as a technology demonstrator for SL1.[4]

On 28 July 2023, the United Kingdom's UK Civil Aviation Authority (CAA) granted HyImpulse permission to launch its SR75 rocket for the first time from SaxaVord Spaceport in Scotland between 1 December 2023 and 30 November 2024.[4] Although SaxaVord is yet to receive its spaceport licence, the CAA has confirmed that the spaceport will not need the licence to host the suborbital SR75 flight due to the 47-kilometre max altitude being targeted and the size of the rocket's engine. [5] However in November 2023 it was announced that the SR75 maiden flight will take place in March 2024 from the Koonibba Test Range in Australia, operated by Southern Launch.[6]

The hybrid rocket engine uses a paraffin-based fuel and liquid oxygen.[7] On 4 September HyImpulse completed its ninth hot fire test campaign. With the successful completion of the testing, HyImpulse qualified its HyPLOX-75 hybrid rocket motor for flight.[8] The motor will be used aboard the SR75 and SL1 first and second stages.
