Complete Analysis and specification of Agni V Ballistic Missile

Complete Analysis and specification of Agni V Ballistic Missile

India  successfully fired Agni-V , the long range Ballistic Nuclear Missile  from Wheeler Island of Orissa. It is capable of attacking any target upto 6000 km away  which is much more than the diameter of China. It has been developed by Defense Research and  development Organization (DRDO) of India.  The estimated cost of making this missile unit is about 40 Crores Indian Rupees.

The technical Specifications of Agni V can be summarized below

Weight: 50,000 kg
Length: 17.5m
Maximum Range:6000km
Warhead: 1000kg on Nuclear Weapon
Engine: 3 Stage Solid
Max Speed: 24 Mach

The Agni-V will be operational by 2014-2015 after four to five repeatable tests by the DRDO.

Agni-V carries  MIRV (multiple independently target-able re-entry vehicles) payloads being concurrently developed. A single MIRVed missile can deliver multiple warheads at different targets.

With a “launch mass” of around 50 tonne and a development cost of over Rs 2,500 crore, Agni-V  incorporates advanced technologies involving ring laser gyroscope and accelerometer for navigation and guidance

On April 19, 2012 at 8.07 am, the Agni V was successfully test fired by DRDO from Wheeler Island off the coast of Orissa.  The test launch was made from the Launch Complex 4 of the Integrated Test Range (ITR) at Wheeler Island using a rail mobile launcher.  The flight time lasted 20 minutes and the third stage fired the re-entry vehicle into the atmosphere at an altitude of 100 kms. The missile re-entry vehicle subsequently impacted the pre-designated target point more than 5,000 kms away in the Indian Ocean.  The director of the test range, S.P. Das informed BBC that all test parameters were met.

Propulsion

The Agni-V is a three stage solid fueled missile with composite motor casing in the third stage. In many aspects, the Agni-5 carries forward the Agni-3 pedigree. With composites used extensively to reduce weight, and a third stage added on (the Agni-3 was a two-stage missile), the Agni-5 can fly 1,500 km further than the 3,500 km range Agni-III. Two stages of this missile will be made of composite material.Advanced technologies like ring laser gyroscope and accelerometer will be used in the new missile.”You can reduce the payload and (further) increase the range of Agni-V” Saraswat told the Reuters in Feb 2010.

Mobility

“The Agni-5 is specially tailored for road-mobility,” explains Avinash Chander, Director, ASL. “With the canister having been successfully developed, all India’s future land-based strategic missiles will be canisterised as well”. The missile will utilize a canister and will be launched from it. Made of maraging steel, a canister must provide a hermitically sealed atmosphere that preserves the missile for years. During firing, the canister must absorb enormous stresses when a thrust of 300 to 400 tonnes is generated to eject the 50-tonne missile.

MIRVs

Agni-V will feature Multiple Independent Re-entry Vehicles (MIRVs) with each missile being capable of carrying 3-10 separate nuclear warheads. Each warhead can be assigned to a different target, separated by hundreds of kilometres; alternatively, two or more warheads can be assigned to one target. MIRVs ensure a credible second strike capability even with few missiles.

INDIA''s Underwater N-missile test successful

INDIA''s  Underwater N-missile test successful

India's elusive nuclear weapon triad - the capability to fire nukes from the land, air and sea - has taken another leap closer to becoming an operational reality. Even as the indigenous nuclear submarine INS Arihant gets ready for sea trials, the country's first underwater ballistic missile "successfully" completed its developmental trials on Sunday.

With this twelfth test of the K-15 missile conducted from a submerged platform or pontoon in the Bay of Bengal, DRDO officials said the 750-km range submarine-launched ballistic missile (SLBM) was now ready for induction.

"The two-stage missile, which rapidly climbed to a 20-km altitude after being launched from the pontoon, was tested for its full range over 700-km. This was its last developmental test, in which all mission objectives were met," said an official.

"Now, the 10-metre tall missile, which can carry a one-tonne nuclear warhead, will undergo a user-trial within a month before it's integrated into the submarine. Only the US, Russia, France and China have successfully developed SLBMs till now," he added.

There is reason to cheer but the bubbly can only be popped once the K-15 missiles are successfully tested from the 6,000-tonne INS Arihant, the country's first indigenous nuclear-powered submarine, which is now all set to undergo "sea-acceptance trials" after its miniature 83 MW pressurized light-water reactor goes "critical" at Visakhapatnam soon.

Navy chief Admiral D K Joshi last month had alluded to this, holding that the nation would get "good news" on this front "very soon". INS Arihant has been undergoing extensive "harbor-acceptance trials", with all its pipelines being "cleared and tested" on shore-based steam for several months now, before its reactor is "fired" for the sea-trials.

Built with four silos to carry 12 K-15s, or four of the 3,500-km range K-4 missiles under-development at present, INS Arihant will of course have to test-fire the 10-tonne missile during the sea trials before it can be said that India's long-awaited nuclear triad has finally become operational.

The first two legs of the triad, already in place with the armed forces, are the Agni series of missiles and fighters like Sukhoi-30MKIs and Mirage-2000s configured to deliver nuclear warheads.

The absence of an operational SLBM, however, has for long left a "big credibility gap" in the country's nuclear deterrence posture. Only a nuclear-powered submarine, which can stay underwater for extended periods, armed with nuclear-tipped missiles can provide a country with effective and difficult-to-detect "second or retaliatory strike capabilities".

But the development of both INS Arihant and K-15 has meandered for well over a decade now. India may now have the INS Chakra, the Akula-II class nuclear-propelled submarine leased from Russia for 10 years, but it did not come armed with "strategic" missiles due to international treaties.

The utility of SSBNs (nuclear submarines with long range missiles) can be gauged from the fact that even the US and Russia are ensuring that two-thirds of the strategic warheads they eventually retain under arms reduction agreements will be in the shape of SLBMs. Consequently, INS Arihant and its three follow-on submarines in the process of being built, along with the K-15 and K-4 missiles, are considered critical for India's "strategic deterrence and autonomy".

The Great INDIAN Netaji Subash Chandra Bose

Today i.e. 23rd January is the 115 th Birthday of Subhash Chandra Bose, the great patriot of India. He was born on January 23, 1897 in Cuttack, Orissa. His father Janaki Nath Bose was a famous lawyer and his mother Prabhavati Devi was a pious and religious lady. Subhas Chandra Bose was the ninth child among fourteen siblings. Subhas Chandra Bose was a brilliant student right from the childhood. He was strongly influenced by Swami Vivekananda's teachings. He joined the Indian civil services in England but deeply disturbed by the Jallianwalla Bagh massacre, and returned to India. He was the first Indian to resign from the Indian Civil Service. The Under Secretary of State for India sent for him. Subhash told him, I do not think one can be loyal to the British Raj and yet serve India honestly, heart and soul.

SubhashChandra Bose advocated complete freedom for India, whereas the congress committee wanted it in phases, through a dominion status but S...
