The Kuwait Space Rocket (KSR), is a Kuwaiti project to build and launch the first suborbital liquid bi-propellant rocket in Arabia.[1] The project is intended to be the first step towards starting a space industry in the country and a launch service provider in the GCC region. The project is divided into two phases with two separate vehicles. An initial testing phase with KSR-1 as a test vehicle capable of reaching an altitude of Template:Cvt and a more expansive suborbital test phase with the KSR-2 planned to fly to an altitude of Template:Cvt.[2]


The project began in January 2018 for conceptual design and planning. The team started the fabrication of KSR-1 in early 2019, and as of January 2020, KSR-1 was fully built.[3]


KSR-1 is a vertically-launched single stage rocket. It uses a liquid bi-propellant rocket engine burning methanol as fuel and nitrous oxide as the oxidizer. KSR-1 is intended to be a test vehicle for the development of KSR-2, the goal of which is to reach space. As such, all the major components and technologies that are expected to be used in KSR-2 are present in KSR-1. The main components of KSR 1 are the engine—consisting of the injector, nozzle, and cooling jacket— with fuel and oxidizer tanks, a nitrogen gas tank, and various valves and pressure regulators.[4]

KSR-1 Development Process

Engine Fabrication

The KSR-1 engine was built locally in Kuwait and it utilizes a pressure fed cycle. The engine utilizes the nitrous not only as an oxidizer but as a cooling agent, that flows around the nozzle and back into the injector again.[5]

Cold Flow Testing

The KSR team performed a cold flow testing on October 2019 to verify the engine's flow rate and plumbing.

Static Testing

KSR performed a static testing of the Injector on November 2019.

Structural Assembly

The KSR-1 was fully assembled and presented at the Kuwait Aviation Show 2020.[6]

KSR-1 Rocket


KSR-2 is a planned liquid bi-propellant suborbital launch vehicle. It is the second installment of the KSR Rocket Family, composed of a single stage, fueled by nitrous oxide and methanol. KSR-2 will have a total length of 4 m, a diameter of 0.4 m and a total mass of 591 kg, its apogee will be around 100 km.
