Indian Hypersonic Propulsion Developments

M7.5 is the peak speed during descent with M4.5 at impact. The only point at which it may of may not achieve M8-9 is during the initial boost phase, but no evidence to prove that either way at this point.
At present the fastest scramjet missile is the South Korean Hycore measured at M6.0 during cruise. At that speed it'll like hit M8+ during descent and impact at >M5.

Hycore has so far demonstrated, as per publicly available information, 5+ seconds of scramjet operation, similar to our HSTDV levels.

The only source I can find quoting time simply says that it exceeded the goal of the test, which was 5s at M5.
South Korea Moves Closer to Deploying Hypersonic Missile
The South Korean military intends to deploy HyCore across multiple platforms.Hypersonic flight refers to speeds of Mach 5 or higher—more than five times the speed of sound. While conventional aircraft and missiles typically operate below Mach 3, hype

Korea's HyCore Hypersonic Missile Approaches Weaponization Stage
** South Korea's HyCore hypersonic cruise missile achieved Mach 6 in tests, nearing weaponization. The multi-platform weapon will deploy on fighters, destroyers, and submarines by 2028.
I've read available sources & one thing that is likely about HyCore Hypersonic cruise missile is that it'll have a range around 800 km at average 5.5 to 6 Mach speed. Though the final number may differ a bit. In comparison to our Indian Hypersonic cruise missile project , it looks like Indian missile will have an upper hand in both speed and range over the S.Korean HyCore. Though it is really inspiring and admirable that this missile will be a great achievement for S.Korea. I don't want to compare Indian Project 'Vishnu' with S.Korean 'HyCore' as of now because of unavailability of exact datas from both sides.The only source I can find quoting time simply says that it exceeded the goal of the test, which was 5s at M5.

India extends run-time of scramjet combustor
India has extended the run-time of an actively cooled full-scale scramjet combustor that is under development for the country's hypersonic weapons programme, the...
www.janes.com
DRDL tested a subscale demonstrator of the scramjet combustor in January 2025. During this maiden test, DRDL operated the subscale combustor continuously for 120 seconds. A follow-up test in April 2025 saw the sub-scale combustor ignited for more than 1,000 seconds. The January 2026 test constituted the first ignition trial of the full-scale combustor.
The combustor employs indigenously developed liquid hydrocarbon endothermic fuel and is equipped with a high temperature thermal barrier coating (TBC), according to the MoD. Janes has previously reported that the combustor's TBC is designed to withstand extreme temperatures beyond the melting point of steel.

1,000km.
They slowdown in the endgame.
Odd thing to do.
I'm guessing it's a guidance problem. The nose shape limits the seeker range?

That's only shown to emphasize the fact that it's a dual mode ramjet that can operate as a scramjet at high altitude or ramjet for lower altitude I think (see images below).
Further reading actually indicates that range is in excess of 1,000km. It does 1,000km hypersonic and can then use engine shutdown and restart to extend range if necessary.
It could be a factor but that would only be relevant for a moving target where a seeker is actually required.

Okay that's it, they want a sea-skimming capability, that's why it's slowing down. After switching off the engine it glides down, then starts the engine in ramjet mode to be able to fly low at supersonic speeds.
Pretty cool. It used hypersonic cruise to reduce time-to-target.
Hypersonic speed at low altitude would require insane heatshields and at the same time result in poor fuel efficiency.
So they basically want a brahmos class weapon but with better launch to hit time. That's pretty nice.

At mach ~5, air starts breaking/dissociating into individual atoms, but the atoms themselves do not break into ions at this speed.
Ionisation of air and subsequent plasma starts forming at significant level from mach 10 onwards.
At mach 5-7 there will be low amount to insignificant amount of plasma.
Kind of not.

It must be possible even at near M10.
