Indian Missile News And Discussion

[Bharat_2009]

with range above 5500 km, Agni II is also an ICBM.



Government of India did a good job by downplaying missile range through Indian media



Funny reports often appear in Indian media like



"Agni III is just 3500 km range but with Agni V (5000 km range), India can target as far as Harbin (North east china)" but not beyond that.



I feel sorry for people of Harbin. They make good beer !!

Qubit: From Shourya's range -payload curve for ballistic flight above, one can see that for Boost Glide profile the range will be what we discussed some time ago.

Hon. Webmsater,



What you're saying is true. However, for A-3 to have a boost glide profile, it needs to have an A-2 type warhead. This necessitates a redesign rendering a possible increase in the diameter and decrease in the length of the existing A-2 warhead. I recall seeing CFD simulations of just such a boost glide optimized warhead, but I don't really remember where.



Does the A-5 have a different solid propellent (higher ISP??) than A-3? If they can pull it off, A-5 will be a good misile. What will stymie it is the abysmal production rate, and of course, RC's "fudge".

No. A3 and A5 fuel ISP is already very good, and a balanced optimum. no ROI for futher improvement because better ISP has other trade-off issues.

What will stymie it is the abysmal production rate, and of course, RC's "fudge".

I a told MMS all but stopped BM missile development and testing. Only recently when Chinese have started dancing on Indian heads that the hold is lifted and Shri AK Anthoney wants 4 wimmen to conceive and deliver the baby in 1 month !!! What f*cked up Indian govt !



The Pinocchio nosed RC is nowhere to be booted out and punished for putting India at this serious handicap.

India all set to test new short-range tactical missile



http://www.thehindu.com/news/national/ar...154015.ece



What's up with this new missile?



Some kind of MBRL tactical nuclear or non nuclear missile with 150 km range !!

[Arun_S]

Finally a true short range battlefield missile, solid fueled, inexpensive, small (compensated by its hi accuracy) and affordable cost missile. Something that Prithvi-1 never was and at best a stop gap measure that did its job last 20 years, and served as stepping stone to hypersonic glide missile Shourya and Sagarika missile.



to achieve low cost yet high accuracy, I think it will use inexpensive flight control system (low cost gryo based) in tandem with RF/optical navigation system to correct errors.

Mr Prasun,



In your first comment you mentioned that the accuracy of SS-150 is dismissal and the system is cumbersome and so on.



Me being witnessed a trial launch,I assure you that the accuracy of the system has been brought down to 4-6mts.Other than the system being a liquid fueled,its still our best choice to take down the enemy targets with a wide variety of targets.Been using the system for a long time and having tested it multiple times,I will place my bet on using this one. All the inventory of 150`s which are ofcourse a huge number running into a number of hundreds has to be expelled to make room for new inventories.

On the other hand you cant compare a system like prithvi to any other contemporary one. Prithvi lies in an entirely different block. IF accuracy is one factor, then its anti-ABM is another factor.



Having been sitting on a huge pile of prithvi inventory, every new technology that goes into the next gen long range missiles is being tested on prithvis first.Before the anti-boost phase ABM system was put onto A-III its been tested on Prithvis. Just like all other INS and warhead detonation mechanisms and so on.

We just have to accept that with no prithvi, there is no further development of missile technology in India.



And regarding your unresearched comment of Prahaar,that its an indigenised LORA, you are completely wrong at it again. It is a spin-off AAD.While LORA is a quasi ballistic missile, Prahaar is not.



My sinciere advice is that, next time when you have to post, do research on it.Just dont post whatever pops in your mind

Arun, the ring laser gyro developed for the A-3, and its advancements for other delivery vehicles, are very sophisticated pieces of work which can match the best developed anywhere. They aren't some "el cheapo" like those on the NoKo or Pakistani delivery vehicles. I don't recall the sources that led me to this assertion, but they were sufficiently credible for me to remember the gist and state that herein. Of course, if you're talking solely about the Prithvi, which I believe you are, it will indeed use a low cost guidance system.

What do you think the cost is. And if it is low enough for a next level of rocket guided rocket artillery ?



IMHO Prahaar seems a tactical artillery weapon for field commanders. So it will be used in large qty and cost is key issue.

Cost of using a ring laser gyro on the Prahar would be too prohibitive. I like the Prahar because it's probably the first proactive move by DRDO. It seems it can be fired in a salvo, which is great! Well, it fills the gap between the Pinaka and the Prithvi, the latter in any case would not be used because TSP would never know the nature of the warhead and might launch a nuclear strike which will escalate out of control. I do however have a question - how far can Prahar+Pinaka+BrahMos go in offsetting the deficiency in the number of 155 mm guns?

[Bharat_2009]

I was wondering whether Prahaar is a supersonic or Hypersonic missile.

Prahaar gross data parameter is not repoted in mainstream media. Only tarmak007 blog reports the following:

[url="http://tarmak007.blogspot.com/"]http://tarmak007.blogspot.com/[/url]

PRAHAAR

The missile with a length of 7.3 meters and diameter of 420 mm weighing 1280 kgs, and a single stage solid propulsion system goes to a height of 35 kms before reaching the targets of the range of 150 kms in about 250 seconds.

Like other Indian missile test reports these numbers indicate it was a non-ballistic flight (depressed ballistic trajectory does not result in that kind of flight time, range and altitude.



The missile sees its MaxQ during ascend (given its AAD / ABM pedgree) at 2 MW drag dissipation. The top speed is 4.5 to 5 Mach.



Clearly there is no need for payload separation thus its does not have a RV, in essence very similar to Shourya in many aspects of flight and maneuver. rolling to spread the heat, and thus in that configuration gliding is a freebee. This craft is capable of glide. and given the claimed precision it will be used in glide mode, with considerably longer range than the claimed 150Km ballistic range. Even the claimed 150 km range with 35 Km apogee is sub optimal.



Lot of data and technology learned from Prithvi and Shourya was applied to used this AAD vehicle as SSM.



------------ Added later ------------



During ballistic decend the velocity is between Mach 2.5 to 3, so the tail fins work well. At such slow speed if flying ballistic trajectory the craft can be taken down by SAM. All the more reason not to fly ballistic trajectory.

Now this 195 second time is compatible with ballistic flight for 150 Km and 35 Km altitude.

July 23, 2011 23:04 IST | Updated: July 23, 2011 23:04 IST



T. S. Subramanian All three stages have been successfully tested at Jagdalpur



Preparations for the launch of Agni-V in December 2011 are gathering speed, with all the three stages of the missile having been successfully tested at Jagdalpur in Chhattisgarh's Bastar district.



Agni-V will be India's most powerful missile, capable of targeting places as far as 5,000 km away with a one-tonne nuclear warhead, giving teeth to the country's nuclear deterrence programme. It will be the missile with the longest range in India's arsenal: in comparison, Agni-III has a range of 3,500 km.



“All the three stages of Agni-V have been tested successfully on the ground,” V.K. Saraswat, Scientific Adviser to the Defence Minister, said on Thursday from Chandipur in Orissa, after the successful launch of India's new missile, Prahaar. “The integration activity of Agni-V is now in progress. Our team, headed by Avinash Chander, is working hard for launching Agni-V in December. It will be a national mission.”



Mr. Chander is Chief Controller (Missiles and Strategic Systems), Defence Research and Development Organisation (DRDO). He earlier worked as Director, Advanced Systems Laboratory, Hyderabad, which has designed all the variants of the Agni missiles, including Agni-V.



DRDO rocket technologists said all the three stages of Agni-V would be fired by solid propellants. The missile, 17.2-metre long and weighing 50 tonnes and with a diameter of two metres, will be launched from a road mobile system from the Wheeler Island off the coast of Orissa.



In 2007, the DRDO developed a large rocket motor-casing made entirely of carbon filament-wound composite, a crucial step towards building Agni-V. This casing will form the third upper stage of the missile.



The DRDO will launch two more missiles by the end of 2011. In August, it will launch Agni-II, which can target places 2,000 km away. It will be launched by the Strategic Forces Command of the Army, which handles nuclear delivery systems. In September, the DRDO will fire the Agni-II Prime missile, which has a range of 2,500 km. The maiden launch of this two-stage missile failed in December 2010, because of a problem in the control system in its first stage.

This configuration is matching what I had predicted many years ago and referred to this un-named missile as Agni-3A (where it has 3 petals of MIRV2A kind) and Agni-3B or Agni-IV ( where it has nose cone with MIRV-5 petals and a SUM(Small upper motor).



What is interesting is that public pictures and information will not show what is inside the nose cone I.e. If it has a SUM thus a true 4 stage missile, and what is the shape and size of the RV contained inside, much less their weight or type.

[url="http://www.samachar.com/Response-to-strike-from-Pakistan-will-be-massive-IAF-chief-lh0oLXgbdbg.html"]Response to strike from Pak will be very heavy: IAF chief[/url]

[url="http://timesofindia.indiatimes.com/toireporter/author-Rajat-Pandit.cms"]Rajat Pandit[/url], TNN & Agencies | Jul 26, 2011, 02.25PM IST NEW DELHI: Indian Air Force (IAF) chief Air Chief Marshal P V Naik on Tuesday said Pakistan's new tactical nuclear missile or expanding arsenal is of no worry to India.



He said [url="http://timesofindia.indiatimes.com/topic/India"]India[/url] followed a 'no-first-use' nuclear policy but warned its response would be "very heavy" in the event of any nuclear attack on the country.



The IAF chief's statement came following the news report that [url="http://timesofindia.indiatimes.com/topic/Pakistan"]Pakistan[/url] planned to add 24 nuclear-capable, short-range missiles capable of hitting all major Indian cities to its arsenal this year.



The plan is in line with Pakistan's official policy of having what is rhetorically called "maintaining a minimum deterrence", especially against India, the daily quoted sources as saying.



"Our nuclear policy is of no first use. It also talks about a very heavy response in case of a nuclear attack. It talks about a retaliatory and hard response, our policy talks about that," Naik, who demits office this Sunday, told a press conference, PTI reported.



Naik was responding to a query on the new Pakistani tactical nuclear missile 'Nasr' which is touted to be a 'game-changer' in future warfare.



He did not agree that the new missile will be a 'game-changer'.



[size="3"][color="#000080"]"Tactical or strategic, it is a nuclear weapon. So, obviously our response would be absolutely violent as per our existing policy[/color][/size]. I don't think it is a game-changer," he added.



Pakistan recently successfully tested 'Nasr', a short-range nuclear capable ballistic missile which can hit targets in the range of 60 kms.



Asked if there was any need to be concerned over the assessment in some quarters that Pakistan had an edge over India in terms of the nuclear warheads, the IAF chief said, "there is no need to be worried on this."



Meanwhile, responding to a query on the role of HAL, Naik said that the aerospace PSU had provided great support to the IAF in the last 50-60 years.



He said already some steps were being initiated by the government to streamline the procedures in the company for "improving the quality".

Thank you ! Indeed a very significant report. Would like to highlight a few important ones:

Raksha Mantri asks DRDO to focus on 5000 km Range Missile Hon’ble Raksha Mantri, Shri AK Antony, addressed the gathering after presenting the DRDO Awards on 03 June 2011. He called upon Defence scientists to deliver the Agni-V missile at the earliest. He said, ‘DRDO must demonstrate its capability to deliver missiles, which can reach the range of 5000 km [color="#A0522D"]at the earliest.[/color] The Interceptor Missile Development Programme has taken India to an elite club of nations that possess the capability to demonstrate missile defence capability. DRDO should now work towards developing a credible ballistic missile defence for our country’. Speaking to reporters later Dr VK Saraswat, SA to RM, said that the Agni-V test launch will take place before this year end.

Life Time Achievement Award for 2010 has been conferred on[color="#A0522D"] Air Cmde (Retd) R Gopalaswami, Defence Research and Development Laboratory ( D R D L ) , Hyderabad, for his exceptional c o n t r i b u t i o n s of the highest order in the development of liquid rocket engines for missiles and multi-fold array of technology and management initiatives.[/color]

DRDO: RECENT ACHIEVEMENTS AT A GLANCE



Defence Research and Development Organisation (DRDO), a premier research establishment of India, is engaged in developing defence technologies covering various disciplines like aeronautics, armaments, electronics, combat vehicles, engineering systems, instrumentation, missiles, advanced computing and simulation, special materials, naval systems, and life sciences. Many important systems were accepted/inducted by the Services. The production value of systems based on technologies developed by DRDO (inducted/accepted/orders) placed during the past one decade is well over 1,10,000 crore.) Some of these technologies have been highlighted here



...... ....



Thus, BrahMos Block II with target discrimination and precision strike capabilities, was test-fired. Similarly, BrahMos Block III with capability for steep diving from high altitudes and high manoeuvers at multiple points during supersonic flight, was also tested. Development of advanced missile systems is a continuous effort and requires systematic development of more and more advanced technologies. Ring Laser Gyro (RLG) based Inertial Navigation System was developed, qualified, and tested. [color="#A0522D"]An Active Radar Seeker for advanced missions was successfully developed. [/color]A Fibre Optics Gyro was successfully developed and tested onboard.



.... .. . .. In tune with changing war scenario, major thrust has been given to develop Unmanned Aerial Vehicles (UAVs). Successful flight trials of Rustom-1, a UAV with endurance of 14 h and altitude ceiling of 8,000 m demonstrated the capabilities for automated/remotely- piloted landing/ take-off and associated technologies.Nishant, another UAV developed by DRDO was ready for induction by the Army. A medium-sized aerostatbased platform was developed for surveillance applications. A novel method was developed and flight-tested for an in-flight structural monitoring of the manned as well as unmanned aircraft structures. The scheme was flight-tested on a Nishant UAV. Besides, over 100 test flights of a 3,000 gm Micro Aerial Vehicle (MAV) designed and developed by DRDO were carried out. A laser seeker kit – ‘Sudarshan’, for 1,000 lb bombs was developed and initial demand for significant number of seeker kits has been received from the Services.





An advanced facility was created to undertake full-scale processing of large rocket motors. The facility was commissioned and the casting of various motors commenced. Pinaka–Multi-barrel Rocket Launcher System was developed and technology transferred to production agencies. Two regiments of Pinaka (worth Rs 1300 crore) have been raised by Army, which is also likely to place orders for another two regiments. The Transfer of Technology (ToT) for multi-mode grenade was completed, for which the Army has placed an order for 10 lakh grenades. Under-barrel Grenade Launcher (UBGL) for INSAS and AK-47 rifles was introduced into the Services with order for 10,000 launchers.





.... . . . In the field of electronics and electro-optics, many systems were inducted/accepted by the services. 3-D medium-range surveillance radar – Rohini and its naval variant, Revathi were inducted. 3-D low-level lightweight radar – Aslesha (for IAF) as well as Bharani (for Army) have been accepted by the Services. The engineered version of upgraded Weapon Locating Radar (WLR – Swathi) developed by DRDO was

realised by the production agency. Electronic Warfare Systems Samyukta (Naval variant) and Sujav were inducted. Orders have been received for the Combat Net Radio (CNR) with anti-jamming features



... .. . . . Advanced materials have been always at the core of weapon systems and military hardware. Significant milestones have been achieved in this critical area. A low-alloy steel DMR-1700 with ultrahigh strength and high fracture toughness has been developed as a cost effective replacement of 250 grade maraging steel. [color="#A0522D"]The alloy was proven by successful demonstration in the intended application[/color][color="#A0522D"].[/color]
