Look, it appears that you don't post here regularly. If you are going to offer your opinion, back it up with some data. Everyone benefits. Otherwise, you're wasting forum bandwidth

Anujan, the Varunastra and Vel are a figment of imagination of Air Marshal S B Deo, former Vice Chief of Air Staff who made models of missiles at home without ANY scientific basic. No wind tunnel testing. No CFD modelling.Anujan wrote:There was a vayu article about this and other missiles some time back:
https://www.vayuaerospace.in/article/53 ... p-missiles
The Varunastra is described as a long range anti-ship missile with cruising speed of 850 kmph. This low cost relatively light weight missile is being developed for neutralising smaller ships as a ‘cost effective solution’. The missile weighs 225 kg, has a 108 kg penetrator and blast fragmentation warhead. The missile has very low RCS and a designed range in excess of 270 km. The Vel is another low RCS platform being developed, a light cruise missile which weighs about 200 kg and can achieve speeds in excess of 270 km for employment against surface targets
The numbers too are without ANY scientific basis.

https://www.livefistdefence.com/2015/10 ... d-off.htmlFormer Vice-Chief of Indian Air Force, Air Marshal SB Deo (retired) offered four missiles of different types to Indian armed forces at the Aero India show on Wednesday.
Deo has personally designed and developed all the missiles. It also includes a 297-km strike range cruise missile Vel and stand-off missile Khagantak.
SB Deo told ANI, "This epitomises Make in India, foreign exchange content is less than 10 per cent. We have two glide bombs of different calibre and a light-weight cruise missile with a range of 297 km that carries a small warhead. They could be inducted in less than 6 months."
Five-day air show Aero India 2019 begun in Bengaluru on Wednesday.
(This story has not been edited by Business Standard staff and is auto-generated from a syndicated feed.)
https://www.livefistdefence.com/2015/03 ... d-off.htmlThe weapons have so far remained concepts given that they have no official sanction and aren’t routed through the established DRDO-DPSU route to service entry. However, Air Marshal Deo and DRDO chief Selvin Christopher today not only shared a warm hug, but also agreed to “work together” — this could mean the DRDO getting involved and helping Air Marshal Deo get the weapons going as inductable platforms.

Honestly a senior officer shouldnt have come up with this kind of unscientific nonsense. His brother was the Attorney General of State of Maharashtra.

Prem Kumar and John are right.
Just because someone writes something doesnt make it true. None of the statistics of the missiles passes the common sense test. And one needs to share facts to substantiate a point of view.
Prem is asking right logical questions. By no stretch of imagination can a 200 kg missile go 270 km!Prem Kumar wrote:A 55Km range missile weighting 380Kg but a 270 Km range missile has a 200Kg weight. Even if we assume that the warheads are of different classes, these numbers seem very odd
As I mentioned earlier, the missiles are a figment of imagination of Air Marshal Deo and not backed up by any scientific research. MOD, IAF, DRDO no one gave any serious thought to it.
The real Varunastra is a 533 mm Heavy Weight Torpedo.
Re: Indian Missiles News & Discussions - 17 Dec 2018
OK, I made a mistake in identifying the trapeze launcher of NGARM as a new one. Kindly ignore that post. My apologies for the wrong post. One doesnt see Russian weapons deployed often and hence their details are not so well known.
Its an old AKU-58 that originally came with Su-30MKI and had Cyrillic lettering identifying it that I missed in the video.
Here is the launcher in full detail -

Was not aware of the colorful history of some of the missile vaporware. Thought vayu was a reliable source, will be careful in the future.

tsarkar saab, yes that launcher is being used for a variety of other missiles that are going to be tested from the Su-30. Many more in the pipeline.
Re: Indian Missiles News & Discussions - 17 Dec 2018
Unless something else has been tested under the guise of Pritivi II, the latest NOTAM would be a damp squib of our expectations of testing of Pralay or XRSAM.

Re: Indian Missiles News & Discussions - 17 Dec 2018
A few nuggets from Rout's article on the Prithvi-2 test:
1) 350Km range, with a 1 tonne warhead. Wiki says Prithvi-2 is a 250Km range missile - not true. Hope they also test (if they haven't already) an extended range Prithvi-2 with a 500Kg warhead
2) Maneuvering trajectory with a single digit CEP
3) Inducted weapon and this was the 2nd night trial in less than a month
4) He said "salvo mode", which was confusing, because only 1 missile was fired
5) The missile's terminal dive can be at an 80 degree angle. Possibly a reverse-slope targeting was tested (similar to Brahmos)

BrahMos tested from INS Chennai today in the Arabian Sea and from Rajnath Singh downwards everyone congratulates. Obviously, there is more to it than meets the eye.

Yep - something cooking. Maybe it was the ER version. It was against a live target. The reports also say that it performed very complex maneuvers.
Re: Indian Missiles News & Discussions - 17 Dec 2018
DRDO Chairman G Satheesh Reddy too congratulated the scientists and all personnel involved in the test-firing of the missile which he said will add to the capabilities of the Indian Armed Forces in many ways.

Re: Indian Missiles News & Discussions - 17 Dec 2018
Chinese target in Tibet are at best 150-200km (mostly sub 100 km) from the Lac. The logistic lines and nodes connecting to Tibet are 500km from Border (Hotan) or 1000km in East. We have many missiles that cover that and I hope in numbers. In a missile dual in my opinion we can dish out more pain than them (mostly owing to geographical limits of chin side, far lesser numbers are needed). It looks like we may only need few types- Brahmos that will meet all objectives but costly and some cheap ssm (prithvi) to complement it.

While the missile has been in India’s arsenal for long, it is continuously upgraded and updated with new hardware and software systems. This is what necessitates periodic tests of the missile. DRDO scientists said that in every such test of a specific variant of Brahmos, different parameters are put to examination. Though the exact details are rarely disclosed, additional hardware and software systems are tested based on the inputs from the user, against more complex targets, and under different atmospheric conditions. The test results and observations are important for future analysis and further advancement, scientists said.

Re: Indian Missiles News & Discussions - 17 Dec 2018
Though not likely but I'm hoping that it was due to new changes that makes it cheaper and faster to produce and that's why everyone's happy.

Re: Indian Missiles News & Discussions - 17 Dec 2018
Brahmos seem to hit targets like we see of Tomahawk. I don't see why we cannot put the same seeker on Nirbhay and deploy it.
Brahmos tests are probably made public, because the Russians would know about any tests. Nirbhay can be tested in Rajasthan, without making it public.

Re: Indian Missiles News & Discussions - 17 Dec 2018
There is generally quite tight coupling of seeker, SWaP (margins) and other mission systems specific to a particular weapon which makes wholesale migration of one system, not designed or optimized for this application in mind, to another system quite a tricky undertaking. For example, there is good reason why the US Navy went to Raytheon to design a clean sheet, missile optimized seeker for the Tomahawk MST+ instead of just asking that a Harpoon or LRASM seeker be integrated into it. Similarly, if you want a highly flexible (as limited a reliance on third party target updates as possible) long range subsonic anti-ship missile (which would be the case for a 1000+ km profile) you also naturally have different volume search requirements that may not exist on a supersonic shorter ranged anti-ship missile. See the passive RF seeker on the LRASM for an example, that allows it organic volume search and target discrimination when third party updates are not available or when LOS data links are jammed or destroyed (which can happen in a war).nam wrote:Brahmos seem to hit targets like we see of Tomahawk.

Current problem with Nirbhay seems to be engine and also ADE seems to be struggling with it. Finally we seem to have hedged our bets and started other subsonic programs in parallel maybe that's kick that ADE needs to get this to finish line.nam wrote:Brahmos seem to hit targets like we see of Tomahawk.

Re: Indian Missiles News & Discussions - 17 Dec 2018
How do you guys surmise the problem with Nirbhay is it's engine? Some reporter said something and that's why?
Re: Indian Missiles News & Discussions - 17 Dec 2018
There's a report that entire missile was recovered from sea so they'll be able to do extremely good failure analysis.

Re: Indian Missiles News & Discussions - 17 Dec 2018
From a cursory glance at specs, HAL PTAE 7 engine proposed for Nirbhay has decent power at 3.7 KN, weight of 65 kg and dia of 0.33 m.
Engine Life of 900 minutes for extended version good enough.
It compares well to Manik's 4-4.2 KN, 130 kg and 0.35 m.
However, the PTAE length is 1.25 m vs 0.95 m for Manik, and being a turbojet, is thirsty with SFC of 1.5 kg/KN-hr.
So, a Nirbhay with PTAE engine might have a range penalty, say 400 -500 km range.
( Good enough for most applications, cheaper and longer range than Brahmos variants, powers that be can still pursue this version. Nirbhay's flight failures is another thing, though).

Re: Indian Missiles News & Discussions - 17 Dec 2018
Was the SANT missile test fired from Rudra or Mi-35 platform? Indian Defence Update on YouTube has claimed that earlier tests of SANT had been carried out from MI-35. About the latest test, there are no details as yet.
But a SANT test is great news for the Rudra and LCH.
