What method of launch will be used is an operational decision that the strategic forces command will take.<br /><br />Sridhar:<br /><br />Dr Saraswat was talking about the flight trajectory, not the propellant. There is no separate liquid oxygen oxidiser.<br /><br />Karupaswamy:<br /><br />Get real. Do you think that adding an artillery piece with a range of 40 kilometers to our arsenal means that all the artillery with lesser range becomes redundant? Each weapons platform, including (in fact, especially) the Brahmos, has its own use. The Shaurya does not replace the Brahmos, it just provides another option to planners.<br /><br />Gagan:<br /><br />What does the MTCR limit have to do with anything?<br /><br />You're right though about the scramjet being tested.

You have a quote from Dr. Saraswat that say...Ajai,<br /><br />You have a quote from Dr. Saraswat that says that this missile has 'hybrid propulsion' and uses solid propellant. As I understand it, the term 'hybrid propulsion' refers to a motor that has a solid propellant but a separate liquid oxidizer (a standard solid motor has the propellant and oxidizer mixed together in solid state). Could you please confirm that this is what the Shaurya has?<br /><br />If indeed it has hybrid propulsion of the type described above, it is a significant technological breakthrough. This is because the separate liquid oxidizer allows for throttling of the missile (by controlling the flow of oxidizer). Thus, the motor could be stopped and restarted, or its thrust controlled. This gives it capabilities similar to a liquid engine, but with the advantages of a solid engine (storability, quick launch). One of the disadvantages of a solid motor that is that it cannot be stopped once it has been ignited (until the fuel runs out) and its thrust cannot be controlled. Hybrid propulsion achieves that.<br /><br />From the reference directly by Dr. S to 'hybrid propulsion' and by reading the rest of your description about the missile's capabilities, I am reasonably inclined to believe that the Shaurya has one or both of its stages with a motor that uses solid propellant and separate oxidizer. Could you please confirm that this is the case?Sridharnoreply@blogger.comtag:blogger.com,1999:blog-8726844009873922462.post-30991634583248497622010-02-18T09:37:17.835-08:002010-02-18T09:37:17.835-08:00Hi Ajai

I used to think that the launch would be similar to the Trident launch video we've all seen. But apparently that is not so. The first stage is a gas generator which fires off underwater and takes the K-15 to 5Km straight.<br /><br />Anon 11:05<br />The range for shaurya mentions 700 Km for a 1 ton warhead. No no Indian N warhead is one ton. The max as predicted by Arun_S is ~450 Kgs - less than a ton. The range can be expected to be ~ 1200 Kms I guess. (I am no missile expert though). MTCR range limit is 300Kms.<br /><br />Anon 11:14<br />I don't think the shaurya will be launched off an aerial platform. DRDO's never said this. It is too big for any aerial platform, unless one missile is slung under a wing of a IL-76, but then what's the point. India is not acquring the Tu-160, and even then it won't fit inside the missile compartment there. The shaurya is meant for land based silos kept 30-50 m underground to protect them from a direct N blast, yet be able to launch off from there if the missile silo doors are opened.<br /><br />Anon 19:49<br />Dearie,<br />DRDO is testing its scramjet. Which world d'ya live in? <br /><br />The scramjet version that is being talked about (is it the one that is small enough to fit on a Mig-29?) is supposed to have a 1000Km range.<br />DRDO could aim to have an ICBM Scramjet too. The future is within reach. This is a platform for which no ABM is likely to be designed to handle for the next 2-3 decades.<br /><br />Ajai-ji<br />Perhaps you can do a peice on DRDO's tech breakthroughs - LCA tejas and the proposed MCA, Arjuns, Brahmos seekers, Hypersonic missiles - shaurya and the scramjet missiles.

It's true if we go all the way to South China sea, which I believe is not a good thing to do with limited subs. The best way is to have a Long range SLBM. Try google earth and you will find that the distance from Andaman sea to cover whole of China is about 5500 kilometers. So if a SLBM version of Agni-V is introduced, then only the Chinese will have to worry about India. I was astonished to find that the Chinese require a 4000km SLBM to target India without crossing the Malacca straits.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8726844009873922462.post-15555024410040770442010-02-17T21:44:38.722-08:002010-02-17T21:44:38.722-08:00Ajai, you reported that "Shaurya is a multi-r...Ajai, you reported that "Shaurya is a multi-role missile that can be fired from the air, land or undersea."

The Shaurya does NOT have Ramjet / Scramjet. Its solid motors power the entire flight. One for each stage - that is two motors.<br />In addition it has one rocket motor for the nose cap.<br />One motor which is the gas generator for initial launch.<br />One motor which is on the side of the body, which gives the missile the rotational movement around its axis when the missile descends from its horizontal flight path. This rotation is necessary since the lower part of the missile nose cone is exposed to maximum air drag, and rotation dissipates some of the heat from the heat shield.<br /><br />That makes a total of 5 rocket motors of varying sizes on the Shaurya.<br /><br />2. Please ask the DRDO what is the difference between the K-15 and the Shaurya? Is it that the seeker is indeginized to a large extent on the shaurya? Also is the ratio of the rocket motors different? On the K-15, the underwater gas generator powers the missile to a height of 5 Km then the second stage motor takes over. Perhaps the trajectory is purely ballistic with glide at the end.<br /><br />3. The CEP of the tomakawk cruise is indeed 1 meter. This is because the guidance is based on Digital Scene Mapping. But it supposedly has everything - waypoints, GPS and then terminal DSM somewhat like TV guidance.Gagannoreply@blogger.comtag:blogger.com,1999:blog-8726844009873922462.post-25407662303153563362010-02-17T15:10:54.823-08:002010-02-17T15:10:54.823-08:00About the launcher in the photograph,
