This is a terrific development.What now remains is to build the remaining SSBNs with an extra section which can house more silos.Ideally,a sub with at least 12 silos would be required,if we are to field just 5 SSBNs for the forseeable future.The first ATVs,Arihant,and 2 follow-ons if of same size,could be reconfigured later on once the larger SSBNs are commissioned with missiles to fulfill the attack/SSGN role.The IN requires at least 6 SSGNs,3 Akulas and 3 indigenous ATVs would be a good number.

In the future,we will definitely require a sub-launched ICBM with a range of at least 5000-7500 km,so that the subs can use the vastness of the IOR to hide themselves in.

The gas generator in itself is an immense achievement being able to push a 3k range missile up the water. Very impressive.

Btw, just struck me - if it is 3K in the depressed trajectory mode, it is definitely higher in pure ballistic mode. So - the actual range of K-4 is even more understated than usual Indian practice.

Adding 12 silos will either need a bigger single reactor or a pair of reactors. else the submerged speed of the boats which are stated as 24knot will decline even further.
note that even modern SSK can manage about 22knot until their batteries run out.
the traditional SSN speed is around 30-35 knots , not sure about SSBN speed but might be 30 knot in the better ones(streamline) like troimphant,yasen,ohio,vanguard.

ofcourse their silent patrol speed is around 6-10 knots onlee.

Le troimphant specs

Displacement: 12,640 tonne (surfaced)
14,335 tonne (submerged)
Length: 138 metres (453 ft)
Beam: 12.50 metres (41.0 ft)
Draught: 10.60 metres (34.8 ft)
Propulsion: K15 pressurised water reactor (150 MW)
16 SLBM

Arihant is 6000t, 112m, with 83MW reactor. so French have a reactor nearly twice as powerful

In fact, in cruise missile mode, it does some energy-bleeding manouevres too in order to avoid being shot down. So, the ballistic missile range is more likely longer. Insh'a All'ah.

How soon can we expect MIRV on the K-4? Will work go on parallel with the MIRVing of A-5? It still has some way to go during tests but in defence world most scientists on a project go to next design when the product begins testing.

imo we do have smaller high yield warhead designs suitable for SLBM/MIRV but the bottleneck is when do we test? without testing there is no point in deploying anything as a prime deterrent.

with compact warheads we can have a third stage around which the warheads are like petals. that will massively up the range to true ICBM figure without impacting the vital length parameter(important for road mobility and sub diameter) and not increasing the weight by much.

moving to composite 1st stage will also reduce weight substantially as the 1st stage is the heaviest...higher the terminal speed at 1st stage burnout, I guess that improves range as well and helps weight saving also to compensate the 3rd stage addition.

^^ The only way SDRE can get a working TN bum without the need to test is to aproach Russia to verify its design based on their tons of data on Nuke Test done and computer simulation and proof test the design in their Laser Ignition Test facility at Sarov

Russia is the only country today that is developing new generation TN charges without testing that is clearly an indicator they are good with their High Energy Physics ( check the Nuclear dhaga in Strat thread for more details )

Whether that is already happening or will happen when Modi comes to power is something we can speculate , much like after 1998 test Vajpayee approached Russia on Nuke Submarine when DAE was going no where with it , we might just approach them.

The other option is to Test it ourself that would need time and political will plus Western Sanction that will definately follow ......not to mention the China/US munna Paki will swear by their butt to test and get a equal equal status ..... would be a strange coincidence if that happens bcoz Nawaz sharif was in power in 1998 when they did the test and he is current PM.

You cant test a complex thing as TN in hurry and in a small window that Vajpayee gave scientist last time ...you need a period of one year to proof test your device go back and fix it and again do it rather then giving our scientist just 3 days like Vajpayee did last time .......we can also test Neutron Bum besides small effecient TN bum if we give enough time to scientist

( Most Western Countries and Russians have perfected TN design over 3 decades of test with multiple design , Hydro Nuclear Test for subcritical test and consqeuntly huge amount of data they have with TN and its physics and Engineering it is bery bery complex as it gets smaller effecient and better )

The last option is not to test at all and just be happy with proven Fission Device and let our accuracy of missile do the talking.

All options are fine just depends on where we want to take the course on Bum Issue which translates to our Posture on Nuclear Deterrence and Political Will

Given that last thing is a precious commodity and the recent accuracy of our IRBM in single digit , I tend to believe that DRDO is hoping for best but prepared for worst i.e last option

No small tn means second class status in icbm field due to less inventory x no mirv.

Meantime cheen is free to use proven designs, plus test via north korea and continue to build on its current superiority.

Thats not acceptable if we want to deter cheen properly and then deal with khan saheb.

Most targets of Military Importance including Deeply Burried one can be take out by a 15 kt Fission Bum that DAE has tested during Shakti test when one looks at Missile Accuracy that DRDO speaks about for Long Range BM.

The Megaton Bum are only of Psychological value during crisis and the desire to Wipe out Civilisation a Cold War Era thinking ..so even though China does have Megaton weapon and so do some P-5 country but we can still inflict unacceptable damage with what we have tested with know conservative yeald figures.

Nirbhay missile has sub-metre accuracy, says DRDO ex-chief
Jeta Pillai

MUSCAT Nirbhay, India’s long range sub-sonic cruise missile, which is undergoing trials, will have sub-metre accuracy, according to Dr VK Saraswat, former director-general of Defence Research and Development Organisation, the developers of the missile.

This will give it the ability to hit a small target among multiple objects at a range of up to 1,000km. The BrahMos supersonic cruise missile, with a range of 300km, has an accuracy of a few metres.


Saraswat, who is currently holder of Department of Atomic Energy’s Homi Bhabha Chair, was presented this year’s ‘Dr ASG Jaykar Award’ at Indian School Wadi Kabir as part of the Science India Fiesta 2014 that concluded on Saturday.

BrahMos, he said, will not be affected even if satellite navigation is jammed because it has a very good homing radar seeker which takes care of all mid-course errors.

About Astra, the active radar homing beyond-visual-range (BVR) air-to-air missile reportedly undergoing trials using Sukhoi 30MKI fighters, he said: It is state-of-the-art, in terms of homing capability, probability of intercept and success rate of the mission. The best aircraft, whatever manoeuvrs it can make, Astra will outwit it.”

Dhanush, a ship launched version of Prithvi missile with a range of 359km, has an accuracy of less than 10m and is mainly for static targets, including those on land, said Saraswat. The missile was test-fired successfully in November 2013.

On the suggestion that India’s Ballistic Missile Defence (BMD) system would disturb military balance in the region, Saraswat said: “It is like any other weapon. When the number of fighter squadrons or tanks, is increased, it will also result in military imbalance.”

But, since India has a policy of no first use of N-weapons, we should have the capability to defend against a rogue N-attack. It must have the time to counter-attack and that is possible only with BMD, which can destroy an incoming missile, he added.

On the possibility of new radars detecting stealth aircraft, he said: “Already there are radars that can detect very low cross-section systems. Aircraft exhaust has infrared (IR) radiation that can be detected, therefore work is on to suppress IR radiation from aircraft. Similarly, ground radars are also becoming more potent with ‘low probability of intercept’ radars and hi-fidelity radars. Then there are passive radars or no transmission radars which only receive signatures from transmissions that are in the environment and then try to find out where they are coming from. With more signal processing techniques, radars will overcome the stealth.”

Saraswat said the level of autonomy in electronic warfare systems on fighter aircraft continues to increase and are able to decide ‘what the threat is, how to overcome it’ and how to make yourself safer against it. “All future radars and radar warning receivers will have that capability and a lot of it is happening today. In many cases missile firing is also done automatically, but

India, he said, was waiting for its first thorium-based reactor to become operational which would be a breakthrough in the effort to meet its energy needs as Kerala had very large deposits of thorium.

Saraswat said the Kaveri engine, which was originally developed for the Light Combat Aircraft ‘Tejas’, had passed all tests and would now be used for large Unmanned Aerial Vehicles that are under development.

I am not sure why he says Brahmos has accuracy of few meters when in past Dr Pillai and other DRDO scientist mentioned it has pin point accuracy and we have videos showing Brahmos hitting radar reflector on a wall bang on in featureless desert condition

Accuracy is the maximum radius within which the missile is guaranteed to hit. A missile can hit the bull's eye for a few tests even when its accuracy is of a few meters. Remember, Prithvi's first launch? Prithvi Point is 27 meters from the designated target. But the accuracy of Prithvi was reported as 150 meters.

Nirbhaya sub meter accuracy is a great news. A cruse missile with a 1000km range will be very very useful against Panda also and will greatly increase our capabilities on the seas. Need to have a huge production line for this. A 1000 Missiles ready to decapitate Paki leadership aimed at their houses all the time is need of the hour.

Mao is reported to have told Brezhnev,that even if Russia killed 400 million Chinese in N-attacks,they would have another 300 million to rebuild the country.More than any other nation,China has built during the Cold War,vast underground shelters for the population,plus putting its most valuable N-assets,etc., underground.It has factored in that a few hundred million of its people will be killed and has taken adequate measures for the survival of the political and military elite.

Unfortunately,thanks to the "peaceniks" in India,steeped in bogus "Gandhian" philosophy,forgetting that Gandhi approved of Indian soldiers fighting in both WW1 and WW2,cheered on by Western entities laughing at our naievety , India has been a most reluctant N-weapons state,almost totally unprepared for nuclear war which is a clear and present danger from Islamist madmen in Pak and its "all-weather friend" China. If we have similar N-war preparedness for the population,etc.,there has been hardly a hint about it.
Therefore it is incumbent upon the new dispensation which is to take charge in Delhi to give serious attention to the possibility,perhaps even probability, that we will face a nuclear attack in the future and prepare for the same.The best defence is to show the enemy that we have an overwhelming response,an assured level of destruction of any state that threatens India or has malevolent designs against it.The day of the long range ICBM has to come, with a range that can strike at any N-power on the globe.

Times of India ‏@timesofindia 3h

Stage set for test of nuclear-capable cruise missile Nirbhay http://timesofindia.indiatimes.com/indi ... 129574.cms
NEW DELHI: India is gearing up to test its first long-range cruise missile 'Nirbhay' (the fearless), which can carry nuclear warheads with a strike range of over 1,000 km, within a month or so.

A stealth missile long in the making, Nirbhay is meant to fulfill the armed forces' demand for nuclear-tipped land-attack cruise missiles (LACMs) versatile enough to be fired from land, air and sea.

Flaunted as India's answer to the famed American Tomahawk missiles as well as an effective counter to Pakistan's Babur LACM, Nirbhay was experimentally fired for the first time in March last year.

But the test went awry. "We had to abort the flight after a snag in one of the components made the missile deviate from its flight trajectory at a waypoint. The problem has now been resolved. The maiden test-firing did prove most of the required critical technologies," said a DRDO scientist.

"Preparations for the fresh test (from the Chandipur launch complex off Odisha coast) are more or less complete. Depending on the slot available, we will test Nirbhay around early-June,'' he added.

India already has the 290-km supersonic BrahMos cruise missile as well as the Agni series of nuclear-capable missiles with strike ranges varying from 700 km to over 5,000 km.

But while BrahMos is a short-range conventional weapon, not a nuclear one, the Agni missiles are ballistic ones that follow a parabolic trajectory. Cruise missiles like Nirbhay are designed to fly at low altitudes, virtually hugging the terrain, to evade enemy radars and missile defence systems. Cruise missiles are also much cheaper and easier to operate than ballistic missiles.

Nirbhay, after an initial blast off with a solid-propellant booster rocket engine to gain speed and altitude, deploys its smallish wings and tail fins in the second stage to fly like an aircraft thereafter.

The sub-sonic missile, which flies at a speed of 0.6-0.7 Mach, is said to be highly maneuverable with "loitering capabilities" to first identify and then hit the intended target. "In the test last year, Nirbhay's launch was perfect. The wings were deployed properly after the 'aircraft engine' took over following the separation of the booster motor from the main missile... the flight had stabilized," said another scientist.

"But we had to resort to the self-destruct mode after there was inertial navigation control failure and the missile began to drift towards the coast. Yes, the missile's turbo-fan is imported as of now but the indigenous engine is also getting ready," the scientist said.

Can't the Nirbhay be modified into a recoverable drone, taking off from some valley in Himalayas and bombing the chinese in a surprise attack with some laser guided glide bomb and the Nirbhay returning to some advance landing zone recovered by deploying a parachute (easy to recover emptied of all fuel and warhead, carrying only the expensive stuff).

For UAV, we do have proper UAV's like Rustom in development that can do the role of UAV's. Nirbhay will be a one time on target missile. One unique feature of this missile is it can be behave like an UAV by loitering over the target area and choosing the time and target before striking. Said to be a feature that's available in Delilah.

Does IR seeker in PDV have different engineering challanges due to its operating enviroment (high altitude, sub zero temp, vacuum etc)?

And is IR seeker alone enough for final engagement?

Watch from 50 sec onwords on how SM3 ASAT version behaves during last stage in LEO (similar to engagement altitues for PDV)

Akash Ready for Second Round Trials
Indian Army and Air Force personnel have planned a series of tests of surface-to-air nuclear capable missile Akash from Thursday. :?:

While in the first phase, three rounds had been planned by the Army wing in an intermittent gap, four rounds would be fired by the Indian Air Force (IAF) personnel. The tests would be conducted from the Integrated Test Range (ITR) at Chandipur-on-sea.

Missile warheads at supersonic speeds, on the ground

CHANDIGARH: India has joined an exclusive club of four countries that can test payloads for missile and rocket technology by simulating a flight environment on the ground.

Terminal Ballistic Research Laboratory (TBRL), a Defence Research and Development Organisation (DRDO) lab in Chandigarh, has indigenously developed the facility known as the Rail Track Rocket Sled Penta Rail Supersonic Track, RTRS in short. It is a four km rail track where the trials are being conducted.

Some confidential tests have already been conducted on this range, which includes recovery of crew capsules in manned space missions. Officials refuse to give more details on this at present.

The facility has come up on a massive property at Ramgarh in Panchkula and was inaugurated on May 12 without much fanfare. "Only Russia, France, the UK and the US are known to have this technology," said Dr Manjit Singh, director TBRL. Now, countries like South Africa have approached us to conduct tests but our priority remains DRDO."

The track will soon be used to test aircraft arrestor gear, which retards aircraft speed during landing or an aborted take-off. "We have also tested this technology for aerospace systems and unmanned aerial vehicles," Dr Singh added.

These simulated tests are needed because real-life experiments can be prohibitively expensive. One can't repeat a test as the material is lost forever. With RTRS, tests can be repeated and the material can be retrieved to study the defects.

The track can withstand maximum velocity of 1,800 km per hour with which components of missiles can be propelled at supersonic speed. The facility will also be able to test interceptor missiles and study air shelling precision.
TBRL is presently working on enhancing RTSR from a payload of 800kg to more than two tonnes. The project cost is around Rs 100 crore. "It has taken us four years to reach here," said Dr PK Khosla, group director, RTRS.

The material to be tested is mounted on a carriage called a 'sled' and can be propelled to a maximum speed of Mach 3.0 with the help of rocket motors. Forty-two camera sheds placed some distance away monitor the velocity, acceleration and other parameters during the trials.
