What Makes Dhvani India’s Most Advanced Missile System
The DRDO’s Dhvani Mach 6 hypersonic missile embodies a revolutionary leap in India’s strategic arsenal. Measuring approximately 9 m in length and 2.5 m in width, its blended wing-body design reduces aerodynamic drag while enhancing lift and stability during flight. Propelled by a two-stage booster and scramjet engine, Dhvani achieves speeds exceeding Mach 6 (7,400 km/h), nearly double the Mach 2.8–3.0 velocity of the BrahMos supersonic cruise missile. This speed advantage compresses enemy reaction windows and renders existing defence systems virtually ineffective.
With an estimated range of 6,000–10,000 km, Dhvani transcends regional strike roles and enters intercontinental strike territory, potentially doubling the reach of India’s Agni-V ICBM. The missile’s stealth features—including ultra-high-temperature ceramic composites capable of withstanding 2,000–3,000 °C during re-entry and radar-defeating angled surfaces—further reduce detectability, ensuring high survivability against advanced sensors and interceptors.

Hypersonic Glide Vehicle Technology Explained
Unlike conventional cruise missiles that rely on sustained propulsion, Dhvani employs a two-stage boost-glide system. In the boost phase, a rocket motor accelerates the vehicle to high supersonic speeds and altitude. Once the booster separates, the glide vehicle descends through the upper atmosphere, using aerodynamic lift to maintain hypersonic velocity without continuous engine thrust. This contrasts sharply with cruise missiles, which burn fuel throughout flight, making them slower and more predictable. Dhvani’s flight profile begins with a sea-launched or ground-launched rocket boost to altitudes above 50 km.
Upon booster separation, the vehicle re-enters the atmosphere, manoeuvring through the terminal phase by executing controlled banking turns and altitude adjustments to evade defences and strike targets with pinpoint accuracy. Heat management is critical at Mach 6+: Dhvani’s thermal protection system uses ultra-high-temperature ceramics and ablative coatings capable of withstanding surface temperatures between 2,000–3,000 °C, preventing structural degradation during atmospheric friction.
Advanced insulation layers and heat-sink designs dissipate energy, safeguarding internal avionics. For guidance, Dhvani integrates inertial navigation, satellite tracking, and terrain-contour matching systems. High-precision gyros and accelerometers maintain orientation, while mid-course GPS updates correct drift. In the terminal phase, onboard seekers compare radar-mapped terrain features to stored digital elevation maps for last-mile accuracy.
Bay of Bengal Testing: Why Odisha ITR Is India’s Hypersonic Hub
The Dhvani Hypersonic Missile Test by END-2025 will leverage Dr. APJ Abdul Kalam Island’s state-of-the-art infrastructure, featuring multiple launch pads, integrated tracking radars, and telemetry stations designed for hypersonic flight trials. This facility, formerly Wheeler Island, supports high-altitude rocket boosts and real-time data acquisition critical for validating glide-vehicle performance.
India’s November 2024 successful long-range hypersonic missile trial off Odisha demonstrated the island’s capability to safely conduct flights over the Bay of Bengal, establishing a proven precedent for Dhvani’s upcoming tests. To facilitate test corridors exceeding 1,500 km, the Directorate General of Civil Aviation issued NOTAMs in October 2025, restricting maritime and airspace access along designated trajectories for the Bay of Bengal missile test.
Strategically situated on India’s eastern coast, the Bay of Bengal offers vast, unpopulated maritime space and predictable weather windows, minimising risk while enabling multi-phase flight profiles from boost to terminal glide. The region’s deep waters ensure safe impact zones, and proximity to tracking ships and aircraft enhances data fidelity. Consequently, Odisha’s Integrated Test Range has emerged as the premier national hub for validating India’s cutting-edge hypersonic weapons.
Dhvani vs BrahMos: Speed Revolution in Indian Arsenal
The Dhvani Hypersonic Missile Test by END-2025 marks a seismic shift in India’s strike capability when compared to the legacy BrahMos. In terms of speed, Dhvani achieves Mach 6+ (approximately 7,400 km/h), nearly double the Mach 2.8–3.0 velocity of BrahMos. This dramatic increase compresses engagement timelines from minutes to mere seconds, overwhelming modern air-and-missile defence systems designed to track slower supersonic threats.
Regarding range, Dhvani’s projected 6,000–10,000 km reach eclipses BrahMos’s 290–650 km envelope by an order of magnitude. Such an extended stand-off distance enables intercontinental strike profiles and deep strategic penetration, far beyond the tactical coastal and regional roles of BrahMos.
In the terminal phase, Dhvani’s hypersonic glide vehicle performs high-G manoeuvres and unpredictable flight-path corrections, starkly contrasting BrahMos’s relatively linear supersonic descent. These abrupt course changes render interception by surface-to-air missiles and shipborne Aegis-class radars highly improbable. Moreover, Dhvani’s payload capacity of 300–500 kg, accommodating both conventional and nuclear warheads, matches BrahMos while leveraging far greater delivery speed and distance.
Looking ahead, the development of a BrahMos-II hypersonic variant under DRDO’s Project Vishnu will harmonise supersonic and hypersonic technologies, ensuring seamless integration across India’s missile fleet and reinforcing strategic deterrence.
Technical Breakthrough: From HSTDV to Dhvani
The foundation for Dhvani’s success lies in DRDO’s Hypersonic Technology Demonstrator Vehicle (HSTDV) program. HSTDV’s sea-launched prototype completed critical aerodynamic validation and guidance trials, proving the viability of a two-stage boost-glide architecture. Building on this, a 1,000-second scramjet engine ground test in April 2025 validated sustained supersonic combustion essential for Dhvani’s cruise phase.
Materials innovation played a pivotal role: carbon-carbon thermal shielding and advanced ceramic composites ensure structural integrity at surface temperatures exceeding 2,000 °C during atmospheric re-entry. These materials, combined with ablative coatings, protect internal avionics and fuel systems from extreme heat flux.
Indigenous expertise at the APJ Abdul Kalam Missile Complex has driven every development stage, from design and prototyping to ground testing and integration. This seamless collaboration between DRDO labs and academic partners underscores India’s self-reliant approach to cutting-edge hypersonic weapons technology.
Strategic Impact: India’s Answer to China and Pakistan Threats
India’s development of the Dhvani hypersonic missile system is a clear response to the rapidly evolving threats from China and Pakistan, fundamentally altering the region’s military balance. With China fielding operational hypersonic platforms like the DF-ZF and DF-17, India faced increasing strategic pressure, as those systems could navigate around existing missile shields and deliver strikes at blistering speeds. The Dhvani Hypersonic Missile Test by END-2025 signals that India is no longer behind in the “India-China-Pakistan” hypersonic race, instead asserting its place beside the world’s top powers.
For Pakistan, India’s hypersonic leap decisively outpaces the reach and speed of Shaheen-series ballistic missiles, making any offensive or retaliatory plans vastly more risky for Islamabad. The regional balance takes a dramatic turn: Dhvani’s Mach 6 speeds compress the reaction window to as little as five minutes, drastically reducing decision-making time for adversaries and undermining conventional deterrence models.
This capability also enhances India’s nuclear doctrine, boosting the credibility of its second-strike posture and strengthening national survivability in a crisis. Furthermore, by fielding such cutting-edge systems, India enhances its strategic autonomy within the Indo-Pacific, positioning itself as a technological equal and reliable partner for alliances like the Quad. Overall, Dhvani forces a recalibration of strategies in “India-China-Pakistan” dynamics, increasing deterrence, regional stability, and the nation’s global standing.
