Reference excerpt

Skyroot Aerospace Private Limited is an Indian private aerospace manufacturer and commercial launch service provider headquartered in Hyderabad, Telangana. The company was founded by two former ISRO scientists, Pawan Kumar Chandana, and Naga Bharath Daka. On 18 November 2022, Skyroot became the first private company in India to launch a suborbital rocket, Vikram-S. On 18 July 2026, Skyroot successfully launched India's first private orbital class rocket Vikram-1 into orbit, making India the third country with a private orbital launch capability after the U.S. and China.

History

Founding

Skyroot Aerospace was founded in 2018 by former ISRO scientists Pawan Kumar Chandana and Naga Bharath Daka. The company sought to develop commercially competitive launch vehicles for the global small satellite market. The company emerged during a period of increasing government support for private participation in India's space industry. Reforms introduced in 2020 enabled private firms to access certain ISRO facilities and created a regulatory framework under the oversight of Indian National Space Promotion and Authorisation Centre (IN-SPACe).

Early development During its initial years, Skyroot focused on developing launch vehicle technologies, and manufacturing processes aimed at reducing launch costs and production times. The company adopted technologies including carbon-composite structures, 3D printing, and modular launch vehicle designs.

Mission Prarambh

On 18 November 2022, Skyroot launched Vikram-S, a suborbital rocket, from the Satish Dhawan Space Centre in Sriharikota under a mission designated Prarambh (lit. 'the beginning'). Vikram-S used the existing launch pad and ground support system infrastructure provided by the government of India at Satish Dhawan Space Centre (SDSC). The mission reached an altitude of approximately 89.5 km (55.6 mi) and marked the first successful launch of a privately developed rocket from India. The event was widely regarded as a milestone in the development of India's private space industry.

Expansion and funding Following the Vikram-S mission, Skyroot raised capital from domestic and international investors. On 30 October 2023, the company announced that it had raised US$27.5 million in a pre-Series C funding round led by Temasek Holdings that brought its cumulative funding to approximately US$95 million. On 21 January 2025, the Government of Telangana signed a MoU with Skyroot Aerospace at the World Economic Forum to establish a private rocket manufacturing, integration, and testing facility in Telangana with an estimated investment of ₹500 crores. On 7 May 2026, following its latest funding round of approximately US$60 million, Skyroot Aerospace crossed US$1.1 billion in valuation. With this, it became India's first space-tech unicorn.

Mission Aagaman On 2 July 2026, the company announced a launch window from 12 July to 4 August 2026 for its first orbital mission, 'Mission Aagaman' (lit. 'the arrival'), using the Vikram-1 launch vehicle from the SDSC. The mission is intended to demonstrate the rocket's propulsion, guidance, and stage-separation systems while carrying domestic and international payloads. On 18 July 2026, the launch was successful, with the mission meeting all its objectives and deploying payload at an altitude of 450 km (280 mi). Skyroot became the first private Indian company to successfully reach space in its first attempt. This made India the third country in the world after the U.S. and China to have rocket launch by private company.

Hardware

Launch vehicles

Vikram-1

Vikram-1 is a four-stage small-lift launch vehicle. The first launch of Vikram-1 took place on 18 July 2026.

Vikram-2

Vikram-2 is an under-development small-lift launch vehicle. The rocket will use an upper stage cryogenic engine powered by the Dhawan-series rocket engine.

Rocket engines

Solid rocket motors

Kalam-100 The Kalam-100 (named after A. P. J. Abdul Kalam) is the third-stage solid rocket motor of Vikram-1. The stage produces a peak vacuum thrust of approximately 100 kN (or ~10 tons). In April 2025, Skyroot conducted successful static firing of Kalam-100 featuring an advanced flex-nozzle system for thrust vector control. The test lasted over 102 seconds and formed part of the qualification programme for the maiden orbital flight of Vikram-1.

Kalam-250 The Kalam-250 is the second-stage solid rocket motor of Vikram-1. for the second stage of the Vikram-1 launch vehicle. It was successfully static-tested on 27 March 2024 at ISRO's Satish Dhawan Space Centre, validating its 85-second burn and critical propulsion systems.

Kalam-1200 The Kalam-1200 is the first-stage solid rocket motor of Vikram-1. On 8 August 2025, Skyroot Aerospace successfully conducted the first static test of the Kalam-1200 solid rocket motor at SDSC, Sriharikota. The 110 second test validated the booster of the Vikram-1.

Earth-storable rocket engine

Raman-I Raman-I (named after C. V. Raman) is a liquid-fuel upper stage engine of Vikram-1.

Cryogenic rocket engines

Dhawan-I On 25 September 2020, Skyroot Aerospace unveiled the Dhawan-I (named after Satish Dhawan) upper stage cryogenic engine that will power heavier-lift systems such as Vikram-2. This is India's first privately developed small cryogenic engine running on liquefied natural gas (LNG) and liquid oxygen (LOX). Dhawan-I is 3D printed and designed with a regenerative cooling configuration. The engine is made by using superalloys.

Dhawan-II On 5 April 2023, Skyroot announced the successful completion of a 200-second endurance static-fire test of its Dhawan-II engine, showcasing the viability of large-scale additive manufacturing for cryogenic propulsion.

Dhawan-III The Dhawan-III engine represents an evolution of the earlier Dhawan-I and Dhawan-II engines, incorporating improvements aimed at future reusable launch vehicles and advanced upper-stage propulsion systems. In February 2026, Skyroot announced that Dhawan-III had successfully completed a 145-second endurance static-fire test. The firing was conducted on an indigenous mobile test stand designed and built in-house by the company. The test was intended to validate the engine's performance, combustion stability, and operational reliability over an extended duration.

Worked examples

Example 1 — a first encounter with Skyroot Aerospace

Start with the simplest possible case. Write down what Skyroot Aerospace claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Skyroot Aerospace before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Skyroot Aerospace ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Skyroot Aerospace

In research: Skyroot Aerospace appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Skyroot Aerospace in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Skyroot Aerospace is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 establishments in Telangana, Aerospace companies, Aerospace companies of India, so understanding it makes those chapters shorter.
In everyday life: Look for Skyroot Aerospace outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
