Indian Missiles and Munitions Discussion
Re: Indian Missiles and Munitions Discussion
It is also important for nirbhay to court stealth skins (like RAM coating) etc. due to higher possibility of getting homed especially during terminal phase. nirbhay as a platform can be used to experiment next generation of stealth characteristics for ucav.

According to defence sources , the two-stage surface-to-surface missile has a length of six meters, diameter of 0.55 m, wing span 2.7 m and a launch weight of about 1,500 kgs. It can carry a payload of 450 kilograms.
Re: Indian Missiles and Munitions Discussion
I wanted to see what HK Rout had posted. He is quite credible on these matters.
He just confirmed something very important.

Re: Indian Missiles and Munitions Discussion
So it travelled 200 225 miles and they call it half of pre coordinated distanceDefence sources said the stealth missile which was launched from the launching complex-III of the Integrated Test Range (ITR) at Chandipur-on-sea at about 11.50 am deviated from its intended trajectory after 20 minutes of flight.
In a statement, DRDO’s Directorate of Public Interface Director Ravi Kumar Gupta said after travelling approximately half of its pre-coordinated distance, deviations were observed from the missile’s intended course. “Further, flight was terminated to ensure coastal safety,” he stated.
Sources said the missile blasted off from a road mobile launcher and the initial lift up was smooth. “It traveled at a speed of 0.75 Mach and moved away from its designated path mid-way. The missile was then terminated to avoid any untoward incident. However, the system performed well till the deviation was witnessed,” the source added.
That means a (full)range of only 500 miles that is 800 km only?
Designed for chotus that were tested separately the second day in 1998
Re: Indian Missiles and Munitions Discussion
but would it not be too risky to send a thermo on nirbhay?

Re: Indian Missiles and Munitions Discussion
I am willing to bet its the RLG that gave out. The only thing that explains the flight drift after the 2nd way point is if the stable platform sees an anomaly. And the RLG non-performance would match the worry of the scientists about proven system giving up.ramana wrote:While all the new technologies onboard the missile is said to have done their duties, what’s worrying the DRDO scientists is that a proven system might have given up at the crucial time.
Re: Indian Missiles and Munitions Discussion
450kg would be a huge conventional warhead. whatever it hits will be badly impacted.....and in a diving profile at 700kmph add in the unburned fuel also ....

Re: Indian Missiles and Munitions Discussion
I don't know if the reporter is accurate about 550 mm. His "source" may have given him a ballpark figure. I think the diameter is 520 mm. The diagram is from ADE to NAL for the preparation of the wind tunnel model. It must be fairly accurate.PratikDas wrote:Arihant's torpedo tubes are 533 mmmaitya wrote: But but 0.55m > 535mm

Re: Indian Missiles and Munitions Discussion
Thanks, Indranil.
Re: Indian Missiles and Munitions Discussion
Thanks Indranil ... however since the aft-stabilizers/fins don't fold like the Russian Klub missiles, the dia that needs to be kept in mind is 1030mm - so absolutely no way of torpedo launch etc, unless foldable aft-fins are introduced.indranilroy wrote:I don't know if the reporter is accurate about 550 mm.

However if that's introduced, then 520mm dia etc means, it will fit in the torpedo tubes which means some very interesting sub-launched possibilities.

Re: Indian Missiles and Munitions Discussion
^^Has it been mentioned somewhere that the fins do not fold?
Re: Indian Missiles and Munitions Discussion
i dont think they fold
Re: Indian Missiles and Munitions Discussion
No it doesn't fold currently ... pls refer to this just-post-launch picture in Ajay Shukla's blog.
It has barely left the launcher, and the aft fins are clearly visible while the fore fins are not yet deployed.
And actually, if you closely look at the dimensions in Indranil's posted line-drawing above, it will be quite a difficult task to squeeze-in those fins.
As, in the last 810mm of the missile body where both the turbofan and the fins are situated, out of the total 520mm dia available, the turbofan occupies 330mm dia leaving only 190mm to fit in these fins along with the deployment mechanism.

thawk block4 cutaway indicates the fuel tank is in the nose and the engine is inclined down to face the air intake squarely.

Re: Indian Missiles and Munitions Discussion
also the satcom terminal for inflight comms. in earlier blocks it was a fixed target and once fired it could not be retargeted I think.

TOI ticker is reporting that an underwater version of Brahmos has been tested.

Yeah, but not much info

The submarine-launched variant of the BrahMos supersonic cruise missile was successfully testfired today for the first time in the Bay of Bengal, off the coast of Visakhapatnam. The launch and test was successful, with the missile hitting its target 292 km away. Photos shortly.

Does India have a sub that Brahmos SLCM will be used in? Both present and those under-construction.

No... Next line of subs (the P75I, when it happens) is supposed to have the VLS for Brahmos..shyamd wrote:Does India have a sub that Brahmos SLCM will be used in? Both present and those under-construction.

Re: Indian Missiles and Munitions Discussion
Submarine-launched version of BrahMos test fired.
India Wednesday successfully carried out the maiden test firing of the over 290km-range submarine-launched version of BrahMos supersonic cruise missile in the Bay of Bengal becoming the first country in the world to have this capability.
The submarine-launched version of BrahMos was successfully test fired from an underwater pontoon near Visakhapatnam, BrahMos CEO A Sivathanu Pillai said.
This is the first test firing of an underwater supersonic cruise missile anywhere in the world and the missile travelled its complete range of over 290 kms, he said.
He said the performance of the missile during the test launch was "perfect".
Ship and ground-launched versions of the missile have been successfully tested and put into service with the Indian Army and the Navy.
The maiden test of the submarine-launched version of BrahMos comes over a week after the indigenously built long-range subsonic cruise missile Nirbhay failed to hit its target in its first test.
"BrahMos missile is fully ready for fitment in submarines in vertical launch configuration which will make the platform one of the most powerful weapon platforms in the world," Pillai said.
Defence minister AK Antony congratulated DRDO scientists and Russian specialists along with officers of the Indian Navy associated with the project for successful test launch of missile from an underwater platform.

Re: Indian Missiles and Munitions Discussion
From the pics of K-15/B-05 in Jan you could see a part of underwater pontoon ( like 2 ends of a ship). How come you don't see that in case of today's brahmos test? Different pontoon may be?
Re: Indian Missiles and Munitions Discussion
From HR's article in IE
While the Bengaluru-based Aeronautical Development Establishment (ADE) has designed Nirbhay missile, most of its technologies have been derived from pilot less target aircraft Lakshya.
This may be the proof of Lakshya engine powering this missile....

Re: Indian Missiles and Munitions Discussion
if you see the lakshya in HAL museum, the entire vehicle itself would weigh less than the nirbhay warhead. there is a huge diff in size and weight and I dont see any way the PTAE7 could ever power the nirbhay as is.
Re: Indian Missiles and Munitions Discussion
Second GD's views on the PTAE7. Its good for powering a drone like Lakshya. The range of 1000kms shows ita turbofan in order to benefit from the low SFC. A turbojet like a scaled up PTAE7 would need a very large tank of fuel.
Re: Indian Missiles and Munitions Discussion
Looking at complete absence of any pontoon marker etc i wonder if it was the ins chakra that fired it? Does the 23 inch tube of the akula torpedo room enough for brahmos? Notice it came up at an angle...typical when fired vertically from a moving sub or from a torpedo tube.
Re: Indian Missiles and Munitions Discussion
Model of Nirbhay shown along with launcher do have folded tail fins.maitya wrote:No it doesn't fold currently ... pls refer to this just-post-launch picture in Ajay Shukla's blog.
Its been told, Nirbhay scores where Brahmos can't in Navy arsenal that means it can be tube launched too.

6/(length of Tomahawk) X (weight of Tomahawk)?
IIRC I was reading somewhere that max range of Tomahawk at ideal altitude and speed is 2500km but on an effective wartime flight path it is 1500km.
Re: Indian Missiles and Munitions Discussion
^ that range is attributed only to Nuclear Tomahawk. What about block 4?
