After 26 Years, India’s Indigenous Tejas Mk1 Programme Set to Achieve 100-Aircraft Production Milestone by 2027

India’s Tejas Mk1 programme will cross the historic 100‑aircraft production milestone by mid‑to‑late 2027, marking the culmination of a 26‑year journey from prototype to frontline fighter. Hindustan Aeronautics Limited (HAL) has accelerated production despite past engine supply delays, with nearly 20 Mk1A fighters already in advanced assembly stages.

The Tejas Mk1 programme is India’s effort to build its own modern fighter jet instead of relying entirely on imports. It began in the early 1980s as part of the Light Combat Aircraft project, with the first prototype flying in 2001. Over the years, the aircraft has gone through different phases—testing, limited production, and then full operational versions. The Mk1 variant was the first to enter service, and the improved Mk1A version now includes advanced radar, electronic warfare systems, and modern avionics.

Close-Up Video

This breakthrough is highly useful in both supersonic missiles and UAVs because it directly addresses propulsion efficiency, adaptability, and compactness.

For supersonic missiles, an air‑breathing Rotating Detonation Engine (RDE) allows extended range since it doesn’t require carrying oxidizers, reducing weight and increasing payload capacity. Continuous detonation waves sustain thrust at supersonic speeds, enabling faster cruise missiles than current scramjet‑based systems. The aerospike nozzle ensures efficiency across altitudes, which is vital for missiles that must fly low to evade radar or high to maximize range. With a compact thrust class of 5 kN, the engine is well‑suited for tactical cruise missiles, balancing destructive power with deployability.

For UAVs, the RDE’s fuel efficiency extends endurance, making long‑duration surveillance or strike missions more feasible. Its compact size allows integration into smaller UAVs without compromising payload capacity. The high thrust‑to‑weight ratio enables UAVs to carry heavier sensors or weapons while still achieving supersonic dash capability. Additionally, air‑breathing RDEs could power reusable UAV demonstrators or spaceplane concepts, reducing operational costs and opening new possibilities for reusable platforms.

Overall, D‑Propulse’s TRL‑5 RDE is a dual‑use breakthrough: it strengthens India’s missile deterrence by enabling lighter, faster, longer‑range supersonic cruise missiles, while also enhancing UAV endurance and speed, a rare combination globally.

Why It’s Considered “Most Advanced”

Calling D‑Propulse’s 5 kN RDE with aerospike nozzle the “world’s most advanced supersonic missile engine” rests on several disruptive features that set it apart from conventional propulsion systems:

• Rotating Detonation Combustion: Unlike scramjets or turbojets, RDEs harness continuous detonation waves, yielding higher thermal efficiency (up to 25–30% more) and reduced mechanical complexity.
• Aerospike nozzle integration: Maintains thrust efficiency across altitudes, solving the bell‑nozzle limitation. This is rare even in global RDE prototypes.
• Air‑breathing capability: Enables sustained supersonic flight without carrying oxidizers, critical for long‑range cruise missiles.
• TRL‑5 validation: Tested in a relevant environment at a DRDO facility, proving real‑world readiness beyond lab experiments.
• Compact thrust class: 5 kN is ideal for tactical supersonic missiles and UAVs, making it deployable rather than just experimental.

Global Context

• U.S. & Russia: Have demonstrated RDE prototypes, but most remain at TRL‑3/4 (lab scale).
• China: Focused more on scramjets; RDE work is less public.
• India (D‑Propulse): Achieving TRL‑5 with aerospike integration places it ahead in practical supersonic missile propulsion.

Comparative Edge

Engine type	Efficiency	Altitude adaptability	Current maturity
RDE + Aerospike	Highest	Excellent	India TRL‑5
Scramjet	Moderate	Limited	India TRL‑5 combustor
Turbojet	Low	Poor	Mature, outdated for hypersonics

Why “World’s Most Advanced”

• Unique integration: No other startup or nation has publicly demonstrated an air‑breathing RDE with aerospike nozzle at TRL‑5.
• Efficiency + adaptability: Combines detonation efficiency with altitude‑independent thrust.
• Deployment potential: Represents the closest step toward deployable supersonic missile propulsion globally.

It combines efficiency, adaptability, and validated readiness in a way unmatched worldwide, making D‑Propulse’s RDE a benchmark in supersonic missile engine technology.

Strategic Significance

• Efficiency leap: RDEs can reduce fuel consumption while sustaining high thrust‑to‑weight ratios.
• Hypersonic potential: Air‑breathing RDEs with aerospike nozzles could power next‑gen cruise missiles or reusable spaceplanes.
• Startup ecosystem: D‑Propulse’s success highlights India’s growing private‑sector role in advanced aerospace propulsion.
• Global context: Few nations have demonstrated RDEs beyond lab scale; TRL‑5 positions India among early movers in this disruptive technology.

Contextual Comparison

Propulsion type	Efficiency	Scalability	Current Status
RDE	High (detonation‑based)	Compact, modular	Emerging, TRL‑5 in India
Scramjet	Moderate (supersonic combustion)	Large scale	India tested 1,200s combustor
Conventional turbojet	Lower	Mature	Widely deployed

This breakthrough could be a game‑changer for India’s aerospace ambitions, complementing DRDO’s scramjet work and ISRO’s reusable launch vehicle efforts.

NVIDIA's AI Push is Reaching Aircraft, and an Indian eVTOL is Part of the Story

A central theme of Jensen Huang's COMPUTEX keynote this week was Physical AI — the convergence of AI, simulation, robotics and autonomous systems. While much of the AI boom has focused on software, NVIDIA's vision is increasingly centered on intelligent machines operating in the real world. From industrial robots and autonomous systems to digital twins and edge computing, the company is building the technology stack that will power the next generation of physical machines. Increasingly, that vision is extending beyond factories and robotics into sectors such as aerospace.

One of the companies living inside that vision is an Indian aerospace startup called The ePlane Company. Featured during Jensen Huang's keynote, ePlane represents an emerging class of companies using AI, simulation and digital-twin technologies not to build software, but to engineer systems that operate in the physical world.

With this recognition, ePlane becomes only the third eVTOL company in the world to be supported by NVIDIA, and the only one from Asia (for their certification journey).

What distinguishes this partnership from a typical technology endorsement is its depth. ePlane was the first eVTOL company globally to publicly commit to NVIDIA hardware within its onboard avionics architecture, and is now actively pursuing aircraft certification with that hardware integrated into the system. This is a foundational hardware-software co-development programme designed from the ground up to meet aviation-grade certification requirements.

"Being on Jensen's stage at GTC Taipei is not a moment we take lightly," said Prof. Satya Chakraavarthy, Founder and CEO, ePlane. "It is a signal to the world that India is not a follower in this technology cycle. We are co-developing safety-critical systems with the most consequential embedded infrastructure company on the planet, at the standards required for certified flight. That is a different conversation that speaks to the growing maturity and global relevance of India’s aerospace ecosystem.”

For ePlane, the Omniverse integration goes well beyond simulation as a tool. By building physics-accurate digital twin environments that model aircraft behaviour across a comprehensive range of flight conditions, failure modes, and edge cases, the company is able to generate simulation evidence that directly feeds into its DGCA certification pathway. The rigour matches what global aerospace leaders apply, and is now being built indigenously, in Chennai.

"Partnerships like this one do not happen by accident," said Vishnu Ramakrishnan, SVP Customer Strategy & Business Partnerships, ePlane. "They happen when a company's technology is genuinely credible at the global level. Being selected by NVIDIA as a reference for how their platform is applied in certified aviation tells our partners and investors something no pitch deck can: that the world's leading embedded infrastructure company has looked at what we are building and decided it belongs on their stage."

ePlane is currently in the Ground Test Vehicle phase of its first full-scale aircraft, with a Series C fundraise underway.

Electric Jump Take-Off (EJTO) is an emerging aerospace propulsion concept that uses hybrid-electric systems to enable aircraft and drones to lift off vertically or with extremely short runways, combining the efficiency of electric power with the thrust of conventional propulsion.

What Electric Jump Take-Off Means

• Definition: EJTO refers to a hybrid propulsion system where electric motors provide an initial “jump” or vertical thrust to lift the aircraft off the ground, reducing or eliminating the need for long runways.
• Purpose: Designed for short take-off and landing (STOL) or vertical take-off and landing (VTOL) operations, especially in urban or remote environments.
• Hybrid System: Combines electric propulsion (for instant lift and efficiency) with conventional engines (for sustained flight and range).

Key Applications

• Unmanned Aircraft (Drones): EJTO enables drones to operate in confined spaces without runways, useful for logistics, surveillance, and emergency response.
• Regional Air Mobility: Light aircraft can take off from smaller airstrips or even improvised landing zones, expanding connectivity in rural and urban areas.
• Sustainability: Electric boost reduces fuel consumption and emissions during take-off, aligning with global green aviation goals.

Advantages of EJTO

• Reduced Infrastructure Needs: Aircraft can operate without long runways, ideal for congested cities or remote regions.
• Lower Operating Costs: Electric propulsion reduces fuel usage during take-off, one of the most energy-intensive flight phases.
• Enhanced Safety: Hybrid redundancy (electric + conventional) provides backup in case of system failure.
• Environmental Benefits: Lower emissions and noise compared to traditional jet or turboprop take-offs.

Challenges

• Battery Limitations: Current battery technology restricts the duration and intensity of electric boost.
• Integration Complexity: Synchronizing electric and conventional propulsion systems requires advanced control algorithms.
• Certification & Regulation: Aviation authorities must establish new standards for hybrid-electric jump take-off systems.

IAN Alpha Fund Backs D-Propulse Aerospace with ₹25 Crore Investment

(Left to Right) Dr. V. Ramanujachari, Co-founder & CTO, D-Propulse Aerospace; and Saurav Jha, Founder & CEO, D-Propulse Aero

IAN Alpha Fund, the 2nd in the series of IAN Group’s VC fund, has invested ₹25 crores in D-Propulse Aerospace Private Limited to support the development of next-generation aerospace propulsion systems. The investment reflects IAN Group’s commitment to support deep-tech startups aligned to India’s strategic imperatives. D-Propulse’s advanced propulsion technologies bring critical innovation to India’s long-term defence strength and industrial resilience.

D-Propulse is building indigenous Rotating Detonation Engine (RDE) based propulsion systems that fundamentally change how high-speed platforms are designed, manufactured, and deployed. Unlike conventional jet engines, RDEs have no moving parts. In fact, they are mechanically simpler, easier to manufacture, and more reliable at scale than even traditional ramjets and scramjets. They also deliver 25% or higher thermal efficiency gains, enabling smaller engines to deliver higher performance.

This combination brings down system costs significantly. By offering performance comparable to today’s high-speed weapons at a fraction of the cost, the company seeks to enable “mass in precision”, the ability to deploy fast, accurate systems at scale.

Founded in July 2025, D-Propulse was created to address a long-standing weakness in India’s defence ecosystem: advanced aero-propulsion. As integrated air and missile defence systems mature globally, traditional radar stealth is losing effectiveness. In the unipolar world of today, there is a need for countries to shift to build self-dependence in critical areas of defence and adoption of high-supersonic and hypersonic platforms is one such need., Existing propulsion technologies make the systems large, expensive, and difficult to scale which is the problem that D-Propulse is targeting to solve for in both defence and industry.

The company is led by an experienced team with strategic insights drawn from India’s defence and research ecosystem. Dr V.K. Saraswat, Member, NITI Aayog and former Chairman of DRDO, serves as Chief Mentor. Founder and CEO Saurav Jha is a defence expert who advises the Indian government and leading Indian companies on strategic technology issues. Co-founder and CTO Dr V. Ramanujachari, a former senior DRDO scientist, led India’s scramjet engine programme and played a key role in the propulsion system used in the Akash missile. Prof. S. Chakravarthy, Head of NCCRD at IIT Madras, is Chief Advisor.

This depth of experience translates directly into execution on the ground. D-Propulse has already achieved a significant technology readiness level in air-breathing rotating detonation combustors and is progressing to flight-capable versions for technology demonstration.

Saurav Jha, Founder & CEO, D-propulse Aerospace, said, “We have entered an era where speed is the new stealth. Defence budgets across the major power centres of the world are pivoting in recognition of this new reality. Our vision is to ensure that India is fully equipped to not merely navigate but potentially dominate this emerging era of high-supersonic and hypersonic systems and platforms. Towards that end, we are progressing indigenous air-breathing rotating detonation engine technology and also building bespoke systems around it. Our plans are not limited to developing RDE-powered effectors but extend to the creation of high-supersonic drones as well.”

Rajnish Kapur, Managing Partner, IAN Alpha Fund, said, “Propulsion is the hardest and most capital-intensive problem in high-speed aerospace systems, and it has historically been the limiting factor for scale. What excites us, at IAN, about D-Propulse is not just the choice of Rotating Detonation technology, but the way it fundamentally changes system economics, simpler engines, higher efficiency, and dramatically lower costs. Affordability is the real unlock if India is to move from a few exquisite platforms to true scale. We see D-Propulse’s team that understands both the physics and the strategic context, and are delighted to back them as a long-term partner in building this for India.”

The seed capital from IAN Alpha Fund will be used to expand the engineering team, strengthen computing and simulation capabilities, and set up limited testing infrastructure. The company is also integrating AI into both operations and technical development to accelerate design and validation cycles. Initial engagements with the Indian military are underway, with export markets to be addressed in close consultation with the government at a later stage.

Globally, rotating detonation combustion is emerging as a general-purpose technology with applications across propulsion, rockets, gas turbines, and power generation, representing a potential $100 billion market by 2035. While India currently has limited activity in this space, global interest is accelerating, creating a timely opportunity for indigenous leadership.

With this investment, IAN Alpha Fund reinforces its role as a conviction-driven investor in deep technology, backing teams that combine scientific depth, execution capability, and a clear understanding of how technology shapes strategic needs to deliver high ROIs.
