India Scales Up Hypersonic Missile Push To Counter Emerging Regional Threats

The DRDO confirms that next-generation hypersonic weapons, capable of breaching advanced missile shields, are currently under development with testing phases imminent.

New Delhi: India is significantly accelerating its pursuit of hypersonic weapon systems, a move that could fundamentally alter the balance of power in the Indo-Pacific. Senior officials from the Defence Research and Development Organisation (DRDO) have indicated that the country is currently working on two distinct paths—hypersonic glide vehicles and hypersonic cruise missiles—to ensure the Indian armed forces remain ahead of evolving global threats.

Speaking on the trajectory of India's missile programme, DRDO Chairman Samir V. Kamat noted that these new systems will operate at velocities nearly double that of the current BrahMos supersonic missiles. The sheer speed, combined with the ability to maneuver mid-flight, makes these weapons almost impossible for existing radar and interception systems to track and destroy.

Indigenous scramjet technology progress

A critical component of this push is the development of scramjet engines. Sources within the defence establishment say that India has already achieved a major milestone by successfully testing scramjet propulsion for over 1,000 seconds. This technology is vital for sustained hypersonic flight, where the engine must breathe air at speeds exceeding Mach 5.

While the BrahMos travels at roughly Mach 2.8, the proposed hypersonic missiles are being designed to push boundaries further. "The propulsion systems have shown high stability during initial ground tests," a senior researcher noted, adding that the focus is now on thermal shielding to ensure the missile can withstand the extreme heat generated during high-velocity atmospheric flight.

Testing timelines and induction

The DRDO is reportedly eyeing a five-year window for induction once the project receives formal government clearances. Early developmental trials for a hypersonic glide vehicle are expected to commence shortly. Unlike traditional ballistic missiles that follow a predictable arc, a glide vehicle is launched into space and then re-enters the atmosphere, gliding to its target at hyper-velocity with unpredictable maneuvering.

Additionally, the third phase of testing for advanced anti-ship missiles is scheduled for later this month. These tests are seen as a precursor to integrating faster, more lethal variants into the Indian Navy's arsenal to counter maritime build-ups in the Indian Ocean.

The global hypersonic race

India’s urgency stems from a rapidly shifting global landscape. Currently, Russia and China lead the operational deployment of these systems. Moscow has already deployed the Kinzhal and Zircon missiles, while Beijing’s DF-ZF is a significant concern for regional security.

In contrast, the United States has faced a string of technical hurdles in its AGM-183 ARRW project, highlighting how difficult this technology is to master. For India, achieving this capability is not just about prestige but about maintaining a credible deterrent against sophisticated missile defence umbrellas currently being deployed by its neighbors.

Agni-6 technical readiness confirmed

Amid the focus on hypersonic speed, the DRDO has also clarified its stance on long-range strike capabilities. The organisation is reportedly in a state of "technical readiness" to begin work on the Agni-6, a formidable intercontinental ballistic missile (ICBM).

While the project awaits a formal "green signal" from the Prime Minister’s Office, the specifications are already being discussed in strategic circles. The Agni-6 is expected to feature a range of 10,000 to 12,000 kilometres and will likely be equipped with Multiple Independently Targetable Re-entry Vehicle (MIRV) technology, allowing a single missile to hit several targets simultaneously.

Impact on regional security

Security analysts suggest that the shift toward hypersonic missiles reflects India's transition from a defensive posture to one of "asymmetric deterrence." By possessing weapons that can bypass the S-400 or Patriot-style systems, India ensures that its strike capability remains potent even against the most well-defended adversaries.

The focus for the next two years will remain on perfecting the "thermal management" of these missiles. At such high speeds, the air around the missile turns into plasma, which can interfere with communication and guidance systems. Solving this physics challenge is currently the top priority for scientists at the Hyderabad and APJ Abdul Kalam Island testing facilities.
