Decoding India’s Multilayered Hypersonic Future: How Dhvani, LR-AShM, and ET-LDHCM Will Transform Regional Strategic Deterrence

Decoding India’s Multilayered Hypersonic Future: How Dhvani, LR-AShM, and ET-LDHCM Will Transform Regional Strategic Deterrence


India’s ambition to master hypersonic technology has rapidly shifted from a future goal to a present reality.

The nation is actively developing a comprehensive, multi-tiered hypersonic strike network designed for nuclear deterrence, naval dominance, and highly accurate conventional strikes.

Leading this strategic leap are three highly advanced, interconnected weapon systems: the Dhvani Hypersonic Glide Vehicle (HGV), the Long-Range Anti-Ship Hypersonic Missile (LR-AShM), and the Extended Trajectory Long Duration Hypersonic Cruise Missile (ET-LDHCM).

The Dhvani HGV marks a major milestone for India, introducing a long-range, maneuverable platform capable of delivering nuclear payloads.

Travelling at speeds well over Mach 5, with an estimated reach approaching 10,000 kilometres, Dhvani is designed to glide along the upper atmosphere in an unpredictable flight path.

This extreme maneuverability makes it incredibly difficult for standard ballistic missile defence shields to track and intercept.

Throughout 2026, ongoing trials are expected to prove the reliability of its heat-resistant materials, targeting software, and final-stage navigation—essential features for surviving heavily protected enemy airspace.

Operating alongside India's nuclear deterrent is the LR-AShM, a weapon specifically built to secure the Indian Ocean Region.

With a striking distance of roughly 1,500 kilometres, this hypersonic glide missile can destroy both moving naval vessels and stationary land targets.

It acts as a powerful tool to prevent adversaries from operating freely in Indian waters.

Notably, the LR-AShM relies entirely on locally produced electronics and sensors, ensuring true self-reliance and severing dependence on foreign targeting networks.

Furthermore, the development of land, sea, and air-launched versions of this missile proves that India now views hypersonic weapons as practical tools for active combat, not just ultimate deterrents.

This modern capability builds significantly upon the foundational success of India’s historic first long-range hypersonic flight test conducted from Dr APJ Abdul Kalam Island off the coast of Odisha in late 2024.

Bridging the gap between standard cruise missiles and ultra-fast glide vehicles is the ET-LDHCM, which underwent crucial testing in 2025.

Travelling at blistering speeds exceeding Mach 8 and covering distances greater than 1,500 kilometres, this missile is highly adaptable.

It can change course mid-flight and can be fired from aircraft, naval ships, and ground launchers.

This versatility makes the ET-LDHCM a highly effective weapon for penetrating advanced enemy air defence networks, whether carrying conventional explosives or nuclear warheads.

The driving force behind these advanced missiles is India's recent breakthrough in scramjet engine technology, a triumph built upon years of rigorous research with the Hypersonic Technology Demonstrator Vehicle (HSTDV) program.

In January 2026, the Defence Research and Development Organisation (DRDO) achieved a massive milestone by successfully running an actively cooled scramjet engine on the ground for more than 12 minutes.

This sustained combustion is the vital technological key that allows cruise missiles to maintain hypersonic speeds over long distances, moving India permanently past the phase of short-duration experimental flights.

Together, these advanced systems represent a fundamental change in India's military doctrine.

Instead of relying solely on the threat of retaliation, India is developing the capability to pierce through layered enemy defences and strike with virtually no warning time.

In a geopolitical environment where neighbouring China has already aggressively deployed hypersonic weaponry, India is responding not just by matching numbers, but by creating an unpredictable, flexible, and completely indigenous defence ecosystem.
 
I believe Russia is now close to operationalising a new engine, an upgraded derivative of the latest AL-41. By the time India begins manufacturing the Su-57 at our own facilities, this improved engine should be available. Its higher thrust output would be more than sufficient to power all onboard electronics while still providing ample excess power to enable the Su-57 to supercruise at significantly higher Mach numbers.

What India must discuss with our Russian counterparts is the possibility of further improving the aircraft’s stealth shaping and infrared (IR) signature management. These two aspects will be central to achieving true fifth-generation performance.

On the other hand, India is fully capable of integrating advanced indigenous systems, including:

  • 2,400+ TR-module AESA radars
  • Next-generation electronic warfare suites
  • Modern radar warning receivers
  • State-of-the-art RAM coatings
  • A highly refined, combat-proven sensor-fusion architecture
India’s strength in networking and sensor-fusion technology has already been demonstrated. During Operation Sindoor, we successfully integrated data from multiple modules of the Aakash Teer system deployed along the International Border and Line of Control. Using inputs from multiple indigenous sensors — GaN-based radars, IR sensors, RWRs, and other platforms — we created a near–virtual-reality operational picture that dramatically enhanced situational awareness, even in heavy electronic-warfare conditions.

This level of fusion, processing, and real-time display is an area in which India has achieved mastery. If the Su-57 is combined with India’s electronics, avionics, and weapons, one senior officer correctly remarked that it could easily outperform even the formidable F-35.

By the time it is achieved, our sophisticated AI based software, which we prepare for AMCA should be available for installation in SU 57. We can tweak it for Su 57.

What is required now is not prolonged procedural discussions, but focused and exhaustive negotiation to finalise the collaboration framework quickly. Once this is achieved, India can transform the Su-57 from a “good 5th-generation-minus platform” into a truly unmatched fighter, potentially exceeded only by the F-22..

Are they already in prototype or on design stage. I have faith in these missions as rocketry from ISRO have proved except for the recent failures
