Times is reporting test a failure and the missile deviated from its path.

^That thing looks huge, any guesses on its range and payload. Also, is the reusable part really just DDM?

It is not reusable. We have to first cross the milestone of a typical cruise missile banging on the target, next we can bring reusability in future versions. Reusability is the proposed concept for Nibhay or its versions. It might be introduced slowly in the same missile series or in a new missile.

If some one stands next to Tomohawk, guess it will look that long, my guess it should be around 17ft.

I hope they have enough test missiles in inventory to Id error asap and test again in a few weeks if possible. Seems like all initial stages were ok, could be an issue with the guidance, they show graphics of a triple missile launcher and the launcher itself is ready from visuals. A lot of work has been done already interms of road launcher. Missile looks gr8, I would have expected it to be more of a angular stealthy design but I guess the pure vanilla CM design is a low risk option and is stealthy too with adequate RAM coatings and low terrain hugging. I am praying for a quick fix on this.

Missile should be 6m long as expected with added length of booster.

^^Tomahawk of the same size is said to have a range around 2k km (i think), so is this 1k km range thing with a overstated warhead weight? Has any details of the payload weight been released?

This should be considered a successful test as DRDO is claiming. The video gives an awesome picture of the things to come. It is just a matter of time and fixing the bugs. Hell, DRDO is really delivering now. This is what we need to manufacture and rest should be all service to human kind.......Great job DRDO. The 15m flight should instill fear in the hearts of our foes.....

Looking at the video, the missile also looks very robust, meant to sustain all weather conditions of deployments. Absolutely love the launcher, great to see that once its second flight is successful, it is possible in the next few months to test multiple launches simultaneously. I am very happy camper. This partial failure will lead to further improvements and the missile should be a world beater next time around. This thing loitering will turn into perhaps most tech advanced cm out anywhere. I am certain this deviation is a minor issue and a few weeks from now, it will hit its target.

TS Subramanian & Y.Mallikarjun in The Hindu
In a setback to Defence Research and Development Organisation (DRDO) plans, the maiden flight of long-range subsonic cruise missile, Nirbhay (Fearless) had to be terminated within 20 minutes of its launch after it deviated from the path.

A top DRDO official told The Hindu from Chandipur that the flight had to be terminated to ensure "coastal safety".

The missile was launched from a road mobile launcher around 11.45 am from the Integrated Test Range, Chandipur, off the Odisha coast. After flying for more than 15 minutes as per the envisaged path, it deviated and veered towards the coast forcing DRDO scientists to abort the flight. The two-stage, low-altitude missile was flying at a height of 4.5 km when the mission was aborted.

DRDO planned to test the missile for its full range of 1,000 km and established make-shift stations along the East Coast to track the missile during its flight.

Soon after the missile took off, the booster engine kick-started and the first stage was separated and missile cruised ahead at 0.7 Mach.

Avinash Chander Chief Controller (Missiles and Strategic Systems), DRDO, however, said that all the mission objectives were met. He said the cruise capability of the system was established for about 30 per cent of the envisaged range when the missile deviated from its trajectory and drifted. All the parameters till that time were exactly as planned. "All the aspects of cruise vehicle were tested and verified. That is a major achievement", he added.

He said the reasons for deviation were being analysed and it might take a couple of months before the next flight was launched.

The missile has "loitering capability" and could fly from an altitude of 500 meters to 10 km. It could go over and around the hills and would be difficult to detect.

> 4.5km travel means they just wanted to test it in a easily trackable manner. once the basic tests are done it will fly the typical low profile. the fit and paintjob of the missile is nice..looks very "american" for lack of a better word :)

NDTV being allowed to crawl all over it, even prior to launch indicates a message being sent to Cheen and other biraders that we readying a strong danda for them.

Nirbhay looks amazingly similar to the klub missile. If even the dimensions are similar, then our Kilo submarines which have recently been upgraded to carry the klub missiles may be able to carry this baby as well -- meaning that our nuclear deterent may not have to be based exclusively on the Arihant/s!

Missile looks like a 20 ft one , :eek: :eek: 1000km doesn't ad up , Range should be around 1500-2500 . Should fix the problem and re test the missile soon .

My thoughts exactly... this missile looks too perfect and too well made to be a prototype. So unlike what we have been led to believe -- it is quite probable that this missile is not a "first day first show" piece, and neither is this it's first flight.

I believe that what one poster has hinted before on this thread is true -- we the public are being kept at least one year behind the actual developments in the indian missile programme. Good strategy DRDO, keep fooling us!

So the chunky rocket booster separates and the missile's engine kicks in afterwards. Without booster this missile can be carried by Su 30s without much difficulty, methinks.
Additionally, as some other posters have mentioned, the missile looks very glossy and TFTA. Such access to media, that too a private channel before it's 'first' launch sends lots of signals.

Test failures are nothing new. Missile launches fail for one reason or the other even from production batches all over the world. Uber-TFTA Chini-Paki projects are something different.

True indeed, the MKI can easily carry this puppy and I am sure they have designed it from the ground up to be MKI capable.

The missile looks like a combination of the Russian version and the Tomahawk. The range should definitely be longer. The Tomahawk has almost the same dimensions, Length 5.56 m (w/o booster), dia 0.52 m and wingspan 2.67 m.
Against this the Nirbhay has 6.036 m, 0.52 m and 3.2 m. (Dimensions from the sketch posted by Indranil)

All this talk about the missile having a turbo prop or propfan engine seems to be only talk. The missile will most likely have a Turbofan engine, just like the Tomahawk. The air launched version to be used with Su30, should be fairly easy, without the first stage booster. The Sub launched version will be a little more tricky. Also given the length, will probably not fit in the scorpenes. Will have to use Russian standard 533 mm tubes for using this missile.

Also suggests that the Russian Klub missile having the range of 300 Kms for the Land Attack version, with almost the same dimensions is almost laughable. Most likely range limited by software only, to fool the MTCR nonsense.

I too concur IMO i think the design has more similarities with Tomahawk than 3m-14e.

the 3M14E is claimed to use a turbojet engine which might reduce its range vs a proper turbofan seen in more strategic cruise missiles.

But greatness is measured how soon you come back from failure. All the best to DRDO, ADE for next time. Even if It flew flawlessly for 20 min its Fine Sad part is it landed 80 KMs inland in Jagatsingpur Odisha as NDTV says, hope no lives were lost.

A question though, what time Turbofan engine kicks in ? and what happens if booster accelerates it so much that sustaining speed and accelerating force by turbofan becomes impossible and due to thrust lag it drifted ? they way it did !!

I am sure they recovered the debris which is a good thing. That will add to the telemetry data that has been collected and may give info on whether there was a mechanical issue.

The video said the jet engine had worked perfectly and the missile flew 1/3rd of the distance which is 300 km. The booster would not have stayed on for 300 km assuming that is the distance.

my wild theory - one or more of the control surfaces jammed in a certain position, making it deviate continuously.

Plausible but it could be cause by faulty commands or by hardware failure. Anyway a failure of the first few launches is always better than three roaring successes. Failures must occur and show up what is wrong rather than accidental successes where the failures which are waiting to occur simply wait for later.
