MoD Tenders 500 Scramjet Engines to Advance India’s Hypersonic Missile Programme
New Delhi, October 2026: The Ministry of Defence has floated a tender for 500 scramjet propulsion systems for India’s hypersonic missile programme, signalling a major push toward indigenous development of long-range, high-speed strike capabilities. The procurement notice, listed under reference IA: 011-23018861 and also reported as IA-01123018861, points to a larger plan to build out the country’s hypersonic weapons ecosystem rather than a limited one-off research order.
The requirement is notable because scramjet technology is central to sustained hypersonic flight. Designed for speeds above Mach 5, or more than five times the speed of sound, scramjet engines are seen as a key enabler for next-generation hypersonic cruise missiles. Unlike conventional rocket motors, which carry both fuel and oxidiser, a scramjet uses atmospheric oxygen during flight. That makes it possible for a missile to remain powered for longer durations while travelling at hypersonic speeds, which in turn can improve range and manoeuvrability.
The tender comes after a series of long-duration ground tests by the Defence Research and Development Laboratory (DRDL), a major DRDO establishment in Hyderabad. These trials were conducted at the laboratory’s Scramjet Connect Pipe Test (SCPT) Facility, which has been built to evaluate advanced air-breathing propulsion systems. In January 2026, DRDL reported that an actively cooled full-scale scramjet combustor had achieved a run time of more than 12 minutes, or over 700 seconds. That performance was extended further on 9 May 2026, when the combustor demonstrated a run time of more than 1,200 seconds.
According to the source, the tests validated several critical elements of the programme, including the combustor design, the performance of the indigenous test facility, and the use of locally developed liquid hydrocarbon endothermic fuel, high-temperature thermal barrier coatings, and advanced manufacturing processes. Earlier subscale long-duration trials had also been conducted in 2025, indicating that the work has been progressing in stages from smaller-scale validation to full-scale testing.
Defence Minister Rajnath Singh had described the achievements as laying a solid foundation for the Hypersonic Cruise Missile Development Programme. DRDO Chairman Dr. Samir V. Kamat also congratulated the teams involved, saying the work had positioned India at the forefront of advanced aerospace propulsion technologies.
The scale of the new tender is significant in itself. An order for 500 units is far beyond the handful of engines usually required for pure developmental testing, suggesting that planning is underway for production of a scramjet-powered hypersonic cruise missile. The Ministry has not specified the missile system linked to the requirement, and the tender should not be read as confirmation that 500 operational missiles have already been manufactured or inducted. Supplier selection, production, integration, testing and certification will still have to follow.
Even so, the procurement marks a clear step toward moving from laboratory demonstration to a more mature production pathway. If fielded, a scramjet-powered cruise missile would differ substantially from boost-glide hypersonic systems, such as the long-range anti-ship hypersonic missile tested in 2024. Boost-glide weapons are boosted to high speed by a rocket and then continue unpowered, whereas a scramjet-powered cruise missile stays under propulsion for much of its trajectory. That sustained powered flight can make the weapon more difficult to intercept because it can manoeuvre more effectively while maintaining extreme speed.
India’s hypersonic work is spread across several related programmes. Among the most important is the Hypersonic Technology Demonstrator Vehicle (HSTDV), which successfully demonstrated scramjet-powered flight in 2020. Another major effort is Project Vishnu, under which the Extended Trajectory–Long Duration Hypersonic Cruise Missile (ET-LDHCM) is being developed. The ET-LDHCM is intended as a scramjet-powered system capable of speeds of around Mach 8, with a baseline range of more than 1,500 km and the possibility of future extension. The programme also envisages multi-platform launch options.
Related initiatives such as BrahMos-II also explore hypersonic capabilities. Taken together, these projects show that India is trying to develop not just a single weapon, but a wider domestic base in advanced propulsion, missile design and supporting industrial capacity. The tender is expected to support domestic manufacturing, specialised aerospace supply chains and propulsion expertise under the Atmanirbhar Bharat initiative.
The development also comes at a time when hypersonic weapons are drawing intense global attention. China has fielded systems such as the DF-17 and YJ-21, while Russia’s Zircon is among the few reported operational scramjet-powered missiles. These systems are closely watched because hypersonic weapons can compress an adversary’s decision-making time and place heavy pressure on existing air-defence networks due to their speed and manoeuvrability.
For India, the issuance of a tender for 500 scramjet propulsion systems does not by itself mean an operational hypersonic missile fleet is imminent. But it does indicate that the Ministry of Defence is preparing for the next stage: scaling up a technology that has already cleared important ground-test milestones and moving it closer to eventual deployment as part of the country’s long-range precision-strike and deterrence architecture.
