    Nirbhay missile: Why India’s first indigenous long range sub-sonic cruise missile is special

    Nirbhay missile is India's first indigenously designed and developed long range sub-sonic cruise missile! Designed and made by DRDO (Defence Research & Development Organisation), the missile was recently test fired successfully. "The flight test achieved all the mission objectives completely from lift-off till the final splash," said a Ministry of Defence release. The Nirbhay missile can be deployed from multiple platforms, says DRDO. We take a look at some key facts about the Nirbhay missile and why its important for the country:

    According to DRDO, Nirbhay missile is a 1000-km class cruise missile that has the capability to strike "deep" into the enemy's territory. The missile has the capability to loiter and cruise at 0.7 Mach, at altitudes as low as 100 metres, says DRDO.

    After the launch of the missile, its booster motor gets separated. The missile's turbofan engine then gets switched on for further propulsion. The booster motor is required for the initial launch.

    The "fully autonomous" missile is crucial to India's defence and strike capabilities. This is because, cruising at low altitudes, it can avoid detection, says DRDO.

    "The guidance, control and navigation system of the missile is configured around the indigenously designed Ring Laser Gyroscope (RLG) and MEMS based Inertial Navigation System (INS) along with GPS system," says DRDO.

    For the recent trial, the missile cruised for a total time duration of 50 minutes, achieving a range of 647 km.

    This was not the first trial of the homegrown missile. The maiden launch in 2013 had been a partial success. Since then the Nirbhay missile has tasted both success and failure in various trials. Its successful development would provide a definite boost not only to the armed forces, but also the indigenous defence industry and India's capability to design and develop such lethal weapons.

    With Nirbhay missile, India joins the select league of nations that possess the ability to make sub-sonic cruise missiles.

    We need a 2500 km range cruise missile like 3M-54 Klub class so that we can hit most of targets in china

    We use ballistic missiles to hit long range targets, not cruise missiles

    this is huge capability to strike on the sea and land targets.

    Just imagine if you are captain of enemy ship, you will avoid this or be ready to be at the bottom of ship.

    once missile is launch, you can only self destruct it.
    But advantage of missile on aircraft is that it could be called off at last movement.

    range is increased, if you have seen.

    Cruise missiles can flew 100 meters above ground and they are stealthy..
    If you have long range cruise missiles with 2500 km no one prefers ballistic missiles.
    I don't know who is "WE".

    But keeping plane at risk is not viable option.
    Second thought for long range brahmos we need plane for sub sonic we don't need any plane

    We here refers to sane people. No one uses cruise missiles for long range strike, especially first strike. First strike will have to evade SAMs and air defence. The so called complete stealth doesn't apply to cruise missiles as when missiles travel at a speed of 0.6Mach, it will generate air vibrations. Also, the motor will always be on in cruise missiles which will add heat signature.

    So, the missile will be detected even with all stealth additions, by ground based radar, even if at lower distance. But, it won't be invisible as you claim. The range of detection may be lower, say 10km but not zero.

    But, combining with low speed of 220m/s (0.6Mach), the distance to travel even 5km will be 25 seconds which is a big enough time for a SAM to detect and launch interceptors, eve if detected at a short range. Subsonic Cruise missiles are mostly interceptable (95% chance) and hence a poor choice to penetrate air defence. It is good for bombing "primitive people in sandals" but not decent opponent


    The missile launch is not fun game. You don't roll back the decision you made at the last minute. Also, risking a plane for 1 missile is not a good idea. Ballistic missile serves all the purpose of this. The warhead of the ballistic missile can have a small motor with little fuel to steer its way if necessary instead of using slow cruise missile or short ranged Brahmos on a plane

    Long range cruise missiles is very much present in the inventory of Russian and China.Tomahawk latest version has range of about 2500 km. Most of this missiles are not not used in nuclear strike roles but can sport a nuclear warhead. The idea is to hit high value targets in sea and land from a naval or air-launched platform. It is a a substitute for ballistic missile but a supplement of it for conventional strikes.
    In the Indian context we have K-15 (750 km) and K-4 (3500 km) whose land versions are a hybrid version meaning they are launched like a ballistc missile but flies at a much depressed trajectory and cruises all the way upto the target at an altitude of 40 km. They are the best in the class and can also be modified into an aircraft carrier role should the need arise.
    Also future versions of Nirbhay will have 2500 km range similar to the Tomahawk (be rest assured about that).
    On the hypersonic front HDSTV will provide us with the long range high speed platform of the next decade.

    Nirbhay CM on display in R day parade , Is it the first time we are seeing Nirbhay in public display ??? Why would we parade a missile which we have not yet inducted neither completed the testing phase so far ??

    India in past also paraded Trishul system in Rajpath, which never got inducted.

    So being a TD, India could very well display it in public. Same held true for Nirbhay too. But never the less, DRDO and MoD is confident enough that it would be a critical part of Indian arsenal and so this might be the case this time.

    From where you are planning to launch such a cruise missile, a 800km range Brahmos can take out anything in Chengdu. Considering that Chengdu is the base of PLA's theater command, what more targets do you need to hit?

    That said, we do need a >2500 km range cruise missile for naval purposes.

    Two problems:
    1. You have to deploy your Brahmos very close to Sino-India border, that will be suicidal before Indian air force dominate the sky around this vast area;
    2. The price of Brahmos make it impossible to launch in massive scale.

    Ironically, no one use long range cruise missile for moving naval target, effectiveness is too low, flying time is too long, navigation will be a big problem.

    I do not understand what is this 5000kms? Is it aerial refueling or suicide mission?

    Let me sleep :crying:
    Alright. We'll develop 1500 km range Nirbhay first. Its cheap and has good stand off range. Then we can target Chengdu? Next we'll develop a longer ranged version with 2500 km range, enough to target more of mainland China. Happy? Guess not.:laugh:

    By Naval purposes I meant as LACMs launched from Naval ships.

    Now good night.:clock:

    Who is he?? I doubt if he is having basic knowledge of physics. 5000km range of Brahmos. Could it possiblet for a super sonic cruise missile ?? and that too a Air launch version.

    Nope, given that "new" Brahmos has 800-900 km range, IA gets to place TELs 250-300 inside the Indian territory and still cover most of Tibet, atleast the parts that matter. Only places outside of Brahmos' range are PLA & PLAAF bases outside Tibet like Chengdu for example. Air launched Brahmos (450 km+) and SCALP (560 km+) adds high levels flexibility. It also means that PLAAF will be hard-pressed to use them against India in a meaningful way because of the distances involved.

    Subjective opinion.

    1) So far there is no evidence to suggest that India cannot afford a large scale strike against targets of considerable importance. Even at the production run of 1000 LACMs at $3 million each, you are looking at a very small part of budget over the period of 10-15 years.

    2) Brahmos is far more survivable than your random subsonic cruise missile which essentially translates to quality over quantity.

    Prahaar can be other alternative to launch heavy strike with multiple conventional munitions

    Thanks for replying to him. Just a little correction, when he was talking about us having to place Brahmos near the LAC, he was referring to a comment I made earlier about how Chengdu could be targeted with a 800km Brahmos, albeit, with a little danger.

    But its alright, @no smoking is looking out for our safety (how cute). His point is that we should develop and induct the 1500km range Nirbhay quickly and in huge numbers. He must really hate the CPC or maybe he has a grudge against people from Chengdu :laugh:

    BTW @no smoking , Indian Army has 36 ready to fire Brahmos Block-III aimed right at PLA today. The number is only set to rise further into the future. Can you stop a swarm of even 1/2 that number? I don't think so.

    My bad, should have read that more carefully. @no smoking

    In a Sino-Indian confrontation, Chengdu air base is too far off to effectively fulfill it's role. It also means that it'll have high survivability.
