Why it matters

Breaks ISRO's launch monopoly and gives Indian and regional smallsat makers a dedicated home launcher.

Vikram-1 is a four-stage small satellite launcher built by Skyroot Aerospace of Hyderabad, India's first privately developed rocket to reach orbit. Skyroot was founded on 12 June 2018 by two former ISRO engineers, Pawan Kumar Chandana and Naga Bharath Daka, and started in the T-Hub incubator. India's 2020 reforms and 2023 space policy gave private firms access to ISRO launch pads, test stands and other facilities.

Design: three solid stages (Kalam-1200, Kalam-250 and Kalam-100) and a liquid fourth stage, the orbit adjustment module, with four Raman-1 engines burning monomethylhydrazine and nitrogen tetroxide. The structure is all carbon composite and the upper-stage engine is 3D-printed. Capacity is quoted as 350 kg to low Earth orbit by Skyroot's recent releases; other sources give 480 kg to a 500 km, 45° orbit and 290 kg to sun-synchronous orbit.

Key dates: first solid-motor demonstrator (Kalam-5) fired at Solar Industries, Nagpur, December 2020; Kalam-100 full-duration test 5 May 2022, also at Solar's facility; suborbital Vikram-S flight (mission Prarambh) to about 89.5 km, 18 November 2022; Raman-1 qualification at ISRO's Liquid Propulsion Systems Centre, June 2023; Kalam-250 test March 2024; Kalam-1200 first-stage static test at Sriharikota, 8 August 2025. Prime Minister Modi opened Skyroot's Infinity Campus in Hyderabad on 27 November 2025, designed to build one orbital rocket a month.

Setbacks: Skyroot had aimed for a first launch in January 2026; it flew in July 2026. No failures have been reported in the flight programme.

Milestone path

  1. 12 June 2018

    Skyroot Aerospace founded

    Achieved

    Former ISRO engineers Pawan Kumar Chandana and Naga Bharath Daka founded Skyroot in Hyderabad, starting in the T-Hub incubator.

    Why it matters: An early test of whether India's private space sector could build orbital rockets.

  2. December 2020

    First solid-motor demonstrator fired

    Achieved

    Skyroot test-fired its Kalam-5 demonstrator motor at Solar Industries, Nagpur.

    Why it matters: First hardware proof of the company's solid-motor approach, built with an Indian propellant partner.

  3. 5 May 2022

    Third-stage motor full-duration test

    Achieved

    The Kalam-100 third-stage motor completed a full-duration firing at Solar Industries' facility.

    Why it matters: First complete Vikram-1 stage proven on the ground.

  4. 18 November 2022

    Vikram-S suborbital flight

    Latest

    Mission Prarambh flew the single-stage Vikram-S suborbital rocket to about 89.5 km.

    Why it matters: Proved Skyroot could work with ISRO's range and launch processes.
