Designed for both conventional and nuclear missions, the missile can carry warheads weighing between 1,000 and 2,000 kg over a range of approximately 1,500 km. According to defence sources, the missile’s velocity and evasive mid-flight manoeuvrability make it nearly impossible to intercept with current radar and air defence systems.
At the core of the ET-LDHCM is an advanced scramjet engine, which uses atmospheric oxygen for fuel combustion, allowing sustained hypersonic speeds for extended durations.
It should be noted that DRDO has already conducted a successful 1,000-second ground test of the scramjet engine, marking a major milestone in the missile’s development.

Contrary to traditional ballistic missiles, the ET-LDHCM flies at low altitudes, is capable of mid-course corrections, and is built using heat-resistant and oxidation-resistant materials that can withstand extreme environments, including temperatures of up to 2,000°C.

What sets the ET-LDHCM apart is its flexibility. It can be launched from land-based launchers, aircraft, or naval platforms, vastly expanding India’s tactical and strategic strike options. Its pinpoint accuracy and ability to evade interception make it suitable for targeting enemy command centres, radar installations, naval assets, and fortified bunkers.

The missile’s development marks India’s second successful hypersonic programme in less than a year, following its LRAShM long-range hypersonic glide vehicle missile test in November 2024. Once inducted, the ET-LDHCM is expected to shift the regional power balance and significantly enhance India’s deterrence capabilities.

Once testing is complete and the missile is operational, India is expected to deploy the ET-LDHCM across all three services, fortifying its preparedness for future conflicts in an increasingly volatile geopolitical landscape.

I think these specs might be incorrect, especially warhead weight, as it's a confidential programme.

What will be dimension of this HCM.

Looks longer with all Boosters. May be Air launch version will have smaller booster. For now we may have only Land Based Delivery systems and SU30MKI based one. Naval application is still some years away. Maybe P18 Destroyers will be going to hold these baddies.
 
one question to anyone who knows....why we nd others publisize all these sketches of design of weapons, components, function etc?? i know its very little knowledge, but why we even providing that to others??? isnt it better we only show weapon pics nd its specifications. whats it purpose?
You are free to unsee and ignore it, and these are presentations which are given about various projects being worked upon by various R&D labs. They aren't being "provided" to others. And it's not that info regarding under development foreign projects aren't unveiled, although not in such PPT formats like it happens here.

i think u didnt read my comments properly....i know indian nd others r doing that. but i m asking whats their reason to doing it?? they r giving ideas to other countries scientist etc. i m not saying by these presentation etc other countries scientist can make that weapon. but it give a rough idea to others. for example russia make their zircon missile nd also show some presentation. now india, china, USA etc r working their own same hypersonic cruise missile. same case with other weapons. one country made it, later other countries also made that type of weapon.

Providing it to others? The "others" than can biuld/develop scramjet cruise missiles, don't need those.

no...i m saying why we nd other countries publisize their new weapons sketches like design, materials, functionality etc in public forum? i know its very less information , but it still give a basic idea to other countries scientist etc. isnt it better to just show weapon pic nd their specifications. whats it purpose.
like this sketch is providing some information. is it necessary to provide?? whats it benefit. it should be keep in secret. 1750965059727.webp
