Vikram-1 [Skyroot Aerospace]
Vikram-1 is a small orbital launch vehicle developed by Skyroot Aerospace of Hyderabad, India. The vehicle is intended to provide orbital launch services for payloads up to 480 kg.
The purpose of the Vikram-1 is to serve the small satellite launch market by providing access to low Earth orbit (LEO) and Sun-synchronous polar orbit (SSPO). The vehicle provides flexible launch options for different orbital inclinations, including 500 km SSO and 500 km LEO.
The company utilizes a combination of solid propulsion technology and liquid-fuelled orbital maneuvering engines. The launch vehicle is composed of three solid-propellant stages, each with a burn time between 80 and 100 seconds, called Kalam-1200, Kalam-250 and Kalam-100. The final stage is equipped with a cluster of four Raman-1 engines powered by monomethylhydrazine (MMH) and nitrogen tetroxide (NTO), providing a total thrust of 3.4 kN. The Raman engines are designed for precise orbital insertion and final orbit adjustments. Vikram-I is capable of lifting 290 kg into a 500 km Sun-synchronous orbit and 480 kg into a 500 km low Earth orbit at 45° inclination.
The maiden flight of Vikram-1 was planned for September 2025, but has been delayed to July 2026..
