About
Vikram-1 is the orbital-class launch vehicle from Indian private space startup Skyroot Aerospace, named after Dr. Vikram Sarabhai, father of the Indian space program. It is a roughly 20 m tall, four-stage rocket built with an all-carbon-composite airframe: three solid-propellant stages (Kalam-1000, Kalam-250, and Kalam-100) followed by a liquid-propellant upper stage using a cluster of four in-house 3D-printed Raman-I engines burning hypergolic propellants (MMH/NTO) for orbit insertion. It targets the growing global small-satellite launch market, offering dedicated and rideshare access to LEO and SSO. Skyroot’s flight heritage began with the suborbital Vikram-S demonstrator, launched 18 November 2022 from Sriharikota under Mission Prarambh, becoming India’s first privately developed and launched rocket. Vikram-1 itself has not yet flown an orbital mission as of mid-2026; Skyroot announced a maiden orbital launch window of 12 July to 4 August 2026 (Mission Aagaman) from the Satish Dhawan Space Centre, Sriharikota, with rocket stages delivered and stacked on the launch pad by early July 2026. A successful flight would mark India’s first orbital launch by a private company.
