ROKETSAN has actively engaged in a wide range of projects centered around the design, development, and production of missile systems for the past 37 years. Within the space industry, ROKETSAN actively participates in two major areas: space launchers and space propulsion systems. A key ongoing project focuses on the development of a Turkish space launch system, following a gradual development model. As an initial step, two scale sounding rockets were designed to test space technologies and gather data on the space environment. Consequently, Turkiye achieved its first independent access to space in 2017. The primary objective of this project is to develop a low Earth orbit launcher named Şimşek-1, capable of injecting payloads weighing up to 400 kg into an altitude of 550 km.
