Maybe possible for current Supersonic Bramhos to keep it subsonic in Indian Air & then cruising it to supersonic speed afterwords. It'll' involve mammoth work though.
Dude your concept will not work even in case of Bramhos -1. Why??? Because, Bramhos is powered by a ramjet engine and ramjet engines don't have compressors(fans/blades). The moment you slow down the airflow pattern will be affected(less amount of air will come in) which may threaten engine and may cause shutdown(popularly known as flame out problem). To compensate this more fuel needs to be consumed. Another important aspect, after you reduce speed and when you reach terminal stage how you again intend to increase speed, consuming more fuel is the only option. In both cases you increase fuel consumption which threatens the integrity of the missile and exponentially reduces the range of the missile.
Let me tell you there is not even a single ramjet with such a (air) flow control capability. For speed and air flow control on a missile you need to use turbo-jet engine.
You are forgetting the point that Bramhos use an booster as first stage to again the required velocity before the ramjet engine is turned on.
Also i would like to mention to the people who say you can increase the range of the missile by adding one more stage. This is not an easy job, by adding a stage you are changing the aerodynamics of the missile, to ensure integrity and correctness you would be required lots of test and may of the flight data which is proprietary and held by the Russians, this is where they may cause problems. Just look at the example of the pains of adding one more stage to Agni missile. Finally Bramhos is deployed using fixed canisters adding a stage may also cause problems in fixed canisters.

But I highly doubt same logic applies to a Hypersonic missile. Because basically you see the scramjet technology incorporated in hypersonic missile is very complex, rather critical.
In scramjet tech, the air intake is supersonic & the same supersonic airflow is required to be maintained throughout the engine. There is very very short time to mix the fuel on board since the higher velocity of the airflow.This is the main difficulty in realizing the hypersonic speed i.e. speed beyond 5.5 MACH. The air is forced inside, compression & heating is done along with fuel is combusted expanding the gas. Any small irregularity/error in the structural geometry of flying body will result in greatest drag possible.

The compression as well as the exhaust is SUPERSONIC. Depending on the fuel, the kinetic energy of the air and the potential combustion heat release will be equal at around Mach 6+. As the speed increases makes the control of the flow within the combustion chamber more difficult. More speed we achieve difficult it gets to maintain the body in air without destroying it.
However we obtain the so called "HYPERSONIC" speed in the mean time.

Now when you are talking about keeping the initial phase subsonic & further hypersonic stage, its a lot complicated & unnecessary if we can master the hypersonic ability.
Because if tomorrow India or even India+Russia succeed in this technology; forget MTCR, US & every other power will be lining up to buy it with blank cheque in briefcase.

Exactly. I could confidently say about the scramjet used in Hypersonics but was not much known to the ramjet of Bramhos-1.

So bottom line, the idea of keeping missile subsonic in Indian Air & then making it Supersonic/Hypersonic is absurd & unreal....

hi dark sorrow does india has kow-how of ramget technology
Yes, India has some know-how about Ramjet engine but it is not up to the mark. Most the know how was achieved by reverse engineering and analysis of previous generation systems. But we are improving at an exponential rate.
I would also like to add that the speed of missile type of engine used is unrelated.
An missile powered with Ramjet engine may travel at sub-sonic, super-sonic or hyper-sonic velocity.
An missile powered with Scramjet engine may travel at super-sonic or hyper-sonic(here subsonic is highly unlikely).
The engine is classified as Ramjet and Scramjet depending on the rate of combustion, sub-sonic rate of combustion for ramjet and super-sonic rate of combustion for Scramjet.

India successfully test-fires 'maneuverable' BrahMos supersonic cruise missile

BHUBANESHWAR: India on Sunday became the first country to have a 'maneuverable' supersonic cruise missile when it successfully test-fired the vertical-launch version of 290-km range BrahMos from a warship in the Bay of Bengal off the Orissa coast.

"The vertical-launch version of missile was launched at 1130 hours today from Indian Navy ship INS Ranvir and it maneuvered successfully hitting the target ship. It was a perfect hit and a perfect mission," BrahMos aerospace chief A Sivathanu Pillai said.

After today's test, India has become the first and only country in the world to have a "maneuverable supersonic cruise missile in its inventory," he said in New Delhi.

In separate messages, President Pratibha Patil and Defence Minister A K Antony congratulated the BrahMos scientists and the navy for the successful test-launch. Pillai said the software of the missile was improved and today's test proved its capability of maneuverability at supersonic speeds before hitting the target.

"During the test, the missile hit a free-floating ship piercing it above the waterline and destroying it completely," BrahMos officials said.

The test-firing was part of the pre-induction tests by the Navy as moves are afoot to deploy the vertical-launch version of the missile in ships. The weapon system has been designed and developed by the Indo-Russian joint venture company.

All the three Indian Navy's Talwar class ships, under construction in Russia, have been fitted with vertical launchers and many other ships will also be equipped with them, officials said.

The navy had earlier carried out several tests of the BrahMos but most of them had been done from inclined launchers abroad INS Rajput. The missile is already in service with the Navy and its Shivalik class frigates have been equipped with it.

BrahMos has also been inducted into the Army and preparations are on to develop its air-launched and the submarine-launched versions, officials said.

Why not up to the mark??? Indian scientists have successfully integrated ramjet propulsion system in Akash missile.........or it has been sourced from somewhere else........plz enlight..

What kind of "maneuverability" are we talking about? Does the 'maneuverability' tested refer to additional evasive countermeasures against enemy ship air-defenses along multiple axes or to 'plunging manuevers' or something else?

In addition, wasn't the extant Brahmos already maneuverable? Which would mean this refers to 'additional maneuverability'? In which case, I must convey my complimentary pats-on-the-backs to the D.R.D.O. on a feat difficult to achieve.


Anyone with a semblance of technical specifications or theories as to how the 'additional maneuverability' was achieved? P.S.: Questions are purely to galvanize the discussion oooooooooooooooooooo.


What's the progress on regiments 862 and 863 that were being raised with discriminatory seekers? - this one I genuinely need //////////

Oops! Found the answer to me 2nd question:


India tests new, more maneuverable version of cruise missile jointly developed with Russia

Nirmula George
Associated Press Writer

March 21, 2010 | 6:24 a.m.



NEW DELHI (AP) — India successfully tested on Sunday a new, more maneuverable version of its BrahMos supersonic cruise missile that was jointly developed with Russia, an official said.

The missile was fired from a moving warship in the Bay of Bengal, off India's eastern coast, and successfully hit its target, said a defense research official who spoke on condition of anonymity because he was not authorized to speak to the media.

The missile had a vertical lift off from the ship and was then maneuvered to hit the target ship, the Press Trust of India news agency said.

"It was a perfect hit and a perfect mission," PTI quoted the head of the BrahMos project, A. Sivathanu Pillai, as saying.

Pillai said the test proved it was possible to change the direction of the missile at supersonic speeds before hitting the target.

The BrahMos missile, developed with Russia, can carry nuclear and conventional warheads weighing 620 to 660 pounds (280 to 300 kilograms) and has a maximum range of 180 miles (290 kilometers).

The missile can fly at 2.8 times the speed of sound and can be launched from land, ships, submarines and aircraft.

The standard version of the missile has already been tested more than a dozen times, but this was the first test of the new version.

New Delhi and Islamabad regularly test missiles, but normally only give each other advance notice for long-range launches. It was not immediately clear whether India informed Pakistan ahead of Sunday's test.

India's missile arsenal also includes the short-range Prithvi missile, the anti-tank Nag missile, the short-range surface-to-air Trishul missile, and the medium-range Agni missile.

I believe what Pillai referring is excessive evasive S-Maneuver in the terminal phase. This type of tactics in the terminal phase of a supersonic missile makes it very difficult for enemy to intercept or dodge somehow & when we are talking about Bramhos flying at MACH 2.8, dodging it is IMPOSSIBLE as of today!

Although it is claimed that Sunburn missile was once tested with this type of maneuver , never heard of it much though...

I'm afraid Brmhos corporation or Indo-Ruskis will ever leak out any specific details of the maneuvers.... >>>>>>

Naval BrahMos Fired With Supersonic Manoeuver, Bang On Target


Just got off the phone with BrahMos CEO Dr A Sivathanu Pillai, delighted with the 11.30AM test of the Naval BrahMos supersonic cruise missile in a vertical launch from the Indian Navy destroyer INS Ranvir. Dr Pillai reveals the test was specifically aimed at testing the missile's accuracy when its flight path was infused with "diversionary manoueuvers" to mask the general direction of the launcher warship. The missile, vertically launched from a Vertical Launcher built for the BrahMos, was rolled in all directions successfully before before it smashed into the hull of INS Meen a decommissioned target vessel. Photos of actual launch will be posted shortly. Stay tuned.

BrahMos passes vertical test :New Launch Method Gives Supersonic Cruise Missile 360° Range

New Delhi: India on Sunday again tested the Brah-Mos supersonic cruise missile, which the armed forces are already inducting as a ‘precision’ strike weapon, from a moving warship INS Ranvir off the Orissa coast.
“The missile was launched from the vertical launcher fitted on INS Ranvir at a decommissioned target ship, INS Meen, and hit it perfectly. The launch met all mission requirements and was 100% successful,” BrahMos Aerospace chief A S Pillai told TOI.
“The test was important since the missile, which flies at speeds of 2.8 Mach, performed supersonic maneuvering after being launched from the vertical launcher and homed on to the target successfully,” he added.
The Navy has already inducted the 290-km range BrahMos missiles on some warships, having earlier placed orders worth Rs 711 crore for 49 firing units in ‘inclined launcher configurations’. It’s now gearing up to induct these airbreathing missiles in the ‘vertical launcher configuration as well’. This is significant since ‘vertical launchers’ are fitted under the warship’s deck, protecting them from the atmospheric conditions and imparting some stealth to the weapon system. It also allows the missile to be fired in any direction.
“With vertical launchers, the missile can be fired at any target in the entire 360 degree spectrum,” said Pillai. Two such modules, with 16 missiles, are to be fitted in each of the three Kolkata-class P-15A destroyers being built at Mazagon Docks at a cost of Rs 11,662 crore. BrahMos will also arm the three more Talwar-class ‘stealth’ frigates being built at Yantar shipyard in Kaliningrad (Russia) under a Rs 5,514 crore project.
The Army, on its part, is on course to induct two more regiments of the BrahMos Block-II land-attack cruise missiles (LACM), which have been designed as ‘precision strike weapons’ capable of hitting small targets in cluttered urban environments, as first reported by TOI earlier.
Swift induction of BrahMos Block-II is necessary because Pakistan army is inducting its nuclear-capable Babur LACM, developed with China’s help to have a 500-km strike range, in large numbers. BrahMos-II can potentially be used for ‘surgical strikes’ at terror training camps across the border without causing collateral damage.
One regiment of the 290-km range BrahMos-I variant, which consists of 67 missiles, five mobile autonomous launchers on 12x12 Tatra vehicles and two mobile command posts, among other equipment, is already operational in the Army. It had earlier ordered two BrahMos regiments in the first phase at a cost of Rs 8,352 crore.
The BrahMos Block-II variant has been developed to take out a specific small target, with a low radar cross-section, in a multi-target environment.

But the work on submarine and air-launched versions of BrahMos is still going quite slow. While talks with Russia are now in the final stages for BrahMos’ integration with Sukhoi-30MKI fighters, the missile will be tested for the first time from submersible pontoon launchers this year in preparation for their induction on submarines.
Incidentally, India and Russia have also begun preliminary work on a ‘hypersonic’ BrahMos-2 missile capable of flying at a speed between 5 and 7 Mach, as reported earlier. The armed forces’ eventual plan is to have nuclear-tipped LACMs, with strike ranges over 1,500 km. Unlike ballistic missiles like Agni, cruise missiles do not leave the atmosphere and are powered and guided throughout their flight path.
Cruise missiles, which can evade enemy radars and air defence systems since they fly at low altitudes, are also much cheaper as well as more accurate and easier to operate than ballistic missiles.

Bravo BrahMos

The successful flight of the BrahMos missile on March 21 spotlights India's status as a world leader in launching supersonic cruise missiles vertically from moving warships and manoeuvring the missiles at the supersonic speed of 2.8 Mach. Launching a missile in an inclined mode is relatively easy. But lifting off vertically from a rolling and pitching vessel, climbing, turning and cruising horizontally, performing manoeuvres, and precisely hitting the target is technologically a big task. Astonishingly, BrahMos performed its intricate manoeuvres at 2.8 Mach, with its propulsion fully switched on during the whole course of its flight. (Normally, when a missile performs manoeuvres, its engines will not operate.) Another highlight was the advanced indigenous software for way point manoeuvring that enables the low-flying missile to hit a target vessel taking shelter, for instance, behind a rocky island. This was the 22nd launch of BrahMos, a joint venture product of the Defence Research and Development Organisation of India and NPO Mashinostroyenia, a space-missile enterprise of the Russian Federation. BrahMos is a versatile, two-stage missile that is nine metres long and weighs 3.9 tonnes with the canister. It has a range of 290 km. It can carry only non-nuclear warheads. With a flight record demonstrating a high degree of reliability, it has already been inducted into the Navy and the Army. India has ship-to-ship, ship-to-land, land-to-land, and land-to-ship versions of BrahMos.

Nobody in their right mind wants lethal missiles fired to kill, destroy, and inflict damage on civilian targets. Since the BrahMos missile is all about enhancing defence capability, a vertical launch from a ship has several advantages. First, it ensures the vessel's safety because the missile is pushed out vertically and its booster engine is fired in the air, allowing the ship to move away. Secondly, the missile in vertical launch can take on a target lying anywhere in a 360-degree range. Whatever the ship's orientation, the missile can turn in any direction to pursue the target. Thirdly, the vertical placement enables accommodation of more missiles in less space in a warship's cramped environs. The missiles are concealed inside the ship, providing them with long and safe storage and protection against corrosion. With India declaring that it would not use nuclear weapons first against another country, BrahMos becomes a formidable and highly cost-effective defence because it can hit any attacker with speed, power, and precision. Given its fast reaction — it takes off in four minutes from the time the command is given from launch headquarters — the missile has virtually no equal in a hypothetical conventional battlefield. BrahMos is a state-of-the-art demonstration of the great advantages of Indo-Soviet, and now Indo-Russian, defence cooperation.

Brahmos cleared for Air Force



Aiming to provide the country’s defence with an extra edge, the government last week inked a Rs 11,600-crore agreement that will pave the way for formal induction of the Brahmos missile into the Indian Air Force (IAF), besides giving two more regiments of the supersonic land attack system to the Army.


While the missile is already in service with the Navy and Army, this is the first time that a surface-to-surface version of the missile will be inducted into the IAF. This will give the IAF a cutting edge over adversaries in the region and will arm it with the capability of taking out enemy radars and other air defence installations without even sending fighters across the border.



Top sources said the multi-crore agreement with Brahmos Aerospace, a joint venture between the DRDO and Russian company, would enable factory production of advanced versions of the cruise missile that can be launched from aircraft, submarines, ships and land. Capable of attaining speeds between 2.5 and 2.8 mach, Brahmos missiles have a range of about 290 kilometres. “In the next couple of years, we will have different versions of the Brahmos in all the three services,” sources said.

BrahMos attracts delegators at DIMDEX ’10

http://www.brahmand.com/news/BrahMos-attracts-delegators-at-DIMDEX-’10/3495/3/12.html

NEW DELHI (BNS): BrahMos Aerospace has grabbed the most media attention at the opening day of 2nd Doha International Maritime and Defence Exhibition (DIMDEX) on Monday, compared to any other South Asian defence establishment.

"The 100% success achieved in recent times in the firing of missiles from different platforms was a matter of immense pride to its developers,” Gulf Times quoted CEO and MD of BrahMos Aerospace, Dr A S Pillai as saying.

Recently, Indian Navy has successfully tested the BRAHMOS missile from a vertical launcher fitted in a moving warship INS Ranvir.

“All tests proved in no uncertain terms that BRAHMOS cruise missile travels three times faster than sound and renowned missile experts have certified the equipment as one of the fastest missiles developed ever,” he added.

The supersonic cruise missile has a flight range of 290 km with a maximum speed of 2.8 Mach.

“Again, its ability to be fired from different kinds of platforms makes it very unique,” he said.

The BRAHMOS missile operates on “Fire and Forget” principle and it has been launched from multiple platforms based on land, sea, sub-sea and air against sea and land targets.

According to the media report, when queried about the missile's significance in a strategic region as the Middle East, Pillai said it could be effectively used for sea operations in the event of hostilities.

At the opening day, officials from Gulf Cooperation Council (GCC) defence team visited the BrahMos pavilion. “The visit of HH the Heir Apparent Sheikh Tamim bin Hamad al-Thani soon after the inauguration was a big boost to each of us associated with the project,” said Pillai.

The BRAHMOS missile is a Joint Venture between India’s Defence Research and Development Organisation and Russia’s NPO Mashinostroeyenia who have together formed the BrahMos Aerospace Private Limited.
