Brahmos Missile explained

What kind of name is Brahmos?

BrahMos was named after the rivers of the two countries taking part in developing of the cruise missile.

The initial name being taken from the river Brahmaputra  in India and the later part being taken from the River Moskov in Russia

And hence the name BrahMos.

What is Bhramos ?

BrahMos is a supersonic cruise missile that can be launched from submarines, ships, aircraft or land. It is a joint venture between India’s Defence Research and Development Organisation (DRDO) and Russia’s NPO Mashinostroeyenia who have together formed the BrahMos Aerospace Private Limited.

What is a Supersonic cruise missile?

A cruise missile is a guided missile that carries an explosive payload and uses a lifting wing and a propulsion system, usually a jet engine, to allow sustained flight; it is essentially a flying bomb. Cruise missiles are generally designed to carry a large conventional or nuclear warhead many hundreds of kilometers with high accuracy. Modern cruise missiles can travel at supersonic or high subsonic speeds, are self-navigating, and fly on a non-ballistic very low altitude trajectory to avoid radar detection.

Your wikipedia copy paste answer did not satisfy my query..answer it properly !

Think of this missile as a low flying Kamakazi jet plane…filled with bombs.These missiles travel very close to the surface of the earth and there fore avoid radar detection.These are guided by GPS on how to reach the destined path and hit the target

A video will help explain

In the later part of the video you will see that the missile just cruises along the terrain and is very close to the surface of the earth.

This is what a cruise missile is.

So what is a super sonic cruise missile?

These missiles travel faster than the speed of sound, usually using ramjet engines. The range is typically 100-500 km, but can be greater. Guidance systems vary.

What does  “Guidance systems vary” mean?

Because these missile travel so close to the ground and they turn to avoid obstacles like trees and buildings they need a eye in the sky.They also need to have pin point description of their location so that they can accelerate or decelerate their speeds.

A global positioning system is used to provide this to the Cruise missile.

Here the problem is that the GPS is owned by the US and they can turn it off at their time and will and hence forth we cannot rely on them.

We are developing our own version of the GPS called Indian Regional Navigation Satellite System (IRNSS)

It should be done by 2011.And yes it will guide the Brahmos in event of a war.


Anything  else I need to know?

Well you might be interested in the fact that Bhramos 2 has been developed and tested and is curently being inducted in the Indian Army

here is a test video of it.

Hope you like it

BrahMos II is a hypersonic cruise missile that has been lab tested with a speed of 5.26 Mach making it the fastest cruise missile in the world. BrahMos II is expected to be ready by 2013-14 and will arm the Project 15B destroyers of the Indian Navy.


Bhramos 2 to be inducted by 2011

I want to see it in action !

Okay here is a video of it in action.

Please skip to 0:53 seconds for the actual test.

You can see how accurate the missile is.
It hits the triangly thing in the wall.

ATV…. Almost done

ATV

Okay as far as my last posts on ATV

Post 1

Post 2

And now this… the ATV is about to near its completion

You know what this mean….India can build any amount of nuclear Submarines at its will any time it wants.

If it want it will throw down a array of nuclear armed  nuclear submarines  on the ocean floor of china.

Just patiently waiting like a sniper for his prey to emerge…

I am too enthusiastic i guess

But they three are already on their way

And i think i have mentioned about Shaurya which is a silo based missile they can be used as a  SLBM (Submarine launched ballistic missiles).

Well the good news does not end here.It gets better.Here is the catch.

The main  hitch ( i read it some where ) in making the ATV  was the integration of  PWR (Pressurized water reactor) in other words the nuclear reactor, small enough to fit into the submarine. Now with that done we can use the same technology to power  a aircraft carrier .

We currently have a aircraft carrier being made in India here is a link

So what i mean is once this project is finished we can integrate the PWR inside a aircraft carrier and whola …. a nuclear powered Aircraft carrier.

I know it not so simple but then ,,, I am so happy.

I wonder what they will name the new nuclear powered submarines.

All the names have been taken up i guess.Lets see

NEW DELHI, Feb 12 (Reuters) – India’s project to construct three nuclear-powered submarines at a southern India naval base is near completion, officials said on Thursday. “Things are in the final stage now,” A.K. Antony, India’s defence minister, told reporters in the southern city of Bangalore.

NDA wish list 1

Now call this wishful thinking or what ever you may ..these are the things i want the BJP led NDA to do when ever it comes to power in the  center,Hopefully very soon

This post is very long and hence forth i decide to divide it into parts

1.Uss Kitty Hawk

India currently has only one aircraft carrier namely INS Virat….. one more is being built and named as Ins vikramaditya…well i was hoping india could get the USS kitty hawk which is soon to be decommissioned . Then india will be having three aircraft carriers

Well i hear there were strings attached to the Uss Kitty hawk carrier

US will refurbish and give the aircraft carrier to India for free provided india purchase 60 F 18 Hornet.@ US $57 million each

How ever this will not be feasible because i think any sale of more than a billion dollars will have to come under transfer of technology and i don’t think that US will give trillions of dollars of R&D for billions

Lets wait and see if the BJP can do anything about it

Reports: Russian accident sub intended for India

http://news.yahoo.com/s/ap/20081110/ap_on_…6HhzjPN83wQr7sF

By VLADIMIR ISACHENKOV, Associated Press Writer

MOSCOW – India’s navy was supposed to lease the brand-new Russian nuclear submarine that suffered an accident over the weekend which killed 20 people, news reports said Monday.

An Indian naval spokesman would not comment Monday on leasing this or any submarine from Russia — but his boss has said previously that India was interested.

The Akula-class sub was undergoing trials in the Sea of Japan when its fire-extinguishing system activated in error, spewing Freon gas that suffocated the victims and injured 21 others.

Russia’s navy said the submarine itself was not damaged in Saturday’s accident and returned to its Pacific coast port Sunday under its own power.

Russia’s top business dailies Kommersant and Vedomosti reported Monday that the Nerpa was to be handed over to India’s navy next year under a 10-year, $650-million lease.

India previously leased a nuclear-powered submarine from the Soviet Union in 1988-1991, and India’s navy chief, Adm. Sureesh Mehta, was quoted as saying that India was negotiating with Moscow to lease two Russian nuclear submarines, the first of which could arrive next year.

Armed with cruise missiles capable of hitting targets 3,000 kilometers (1,860 miles) away, Akula-class subs are considered the quietest and deadliest of Russian attack submarines. A sub of that class could unsettle the military balance of power in Asia, dramatically bolstering India’s navy capability as it jockeys with China for influence over energy supply routes in the Indian Ocean.

Phone calls to China’s defense and foreign ministries seeking comment rang unanswered Monday night.

Vedomosti quoted an unidentified shipping industries official as saying the sub was intended for India’s navy, which has already named it the Chakra.

Indian naval spokesman Cmdr. Nirad Sinha would not confirm whether the Nerpa was to be leased and said no Indians were on board the submarine when the accident occurred.

“It’s a Russian submarine, and any concerns are Russian concerns,” Sinha told The Associated Press.

Indian news reports said Monday the submarine was to join the southern Asian country’s navy in August. The Indian Express newspaper also reported that Indian sailors had been scheduled to head to Russia later this month for on-board training.

Kommersant, meanwhile, quoted an unnamed shipyard official as saying the delivery of the submarine to India, originally set for August 2007, had been postponed twice already.

As investigators tried to determine what activated the firefighting system, Russian naval experts said overcrowding and human errors may have contributed to the accident.

The Nerpa had 208 people aboard when the accident occurred, including 81 seamen, according to the navy. Akula-class subs normally carry a crew of 73.

Retired submarine Capt. Alexander Pokrovsky said in a commentary that sea trials often pose increased safety risks.

Pokrovsky also criticized Freon-based fire-extinguishing systems, saying they are dangerous for the crew and need to be replaced with safer equipment.

Individual breathing kits should have saved the crew, but some former submariners said civilian shipyard workers usually have little experience in using them. Seventeen of those killed in the accident were civilians, the Russian navy said.

“Civilians were supposed to undergo training, but it usually is pretty informal,” said Igor Kurdin, who heads an association of former submariners. He speculated the fire system could have been triggered by something as simple as someone smoking a cigarette near a safety gauge.

Some commentators also speculated there might not have been enough individual breathing kits for all those aboard during the test.

Advanced Technology Vessel (ATV)

The nuclear haves are increasingly relying on sea-based nuclear deterrence in preference to land and air segments. India has a number of foreign-produced cruise missile systems in its arsenal, to include Exocet, Styx, Starbright, Sea Eagle, and perhaps the Russian Sunburn supersonic missile. It also has some indigenous cruise missile systems under development to include the Sagarika and Lakshya variant.

The Sagarika (Oceanic) began development in 1994 as a submarine-launched cruise missile (SLCM) which will have a range of at least 300 kms (a few claim 1000 kms); it was projected for deployment around 2005. The program has met with considerable delays and the missile is not expected to become operational before 2010. Tt will probably arm India’s nuclear submarine, the Advanced Technology Vessel (ATV).

India is a nation that fights for entering the select group of countries that build nuclear powered submarines. Its program ATV, or Advanced Technology Vessel, was initiated in 1974. But aftre three decades it still had not presented results that could modify the current picture of the navies with nuclear propulsion.

India has been working actively since 1985 to develop an indigenously constructed nuclear-powered submarine, one that was based on the Soviet Charlie II-class design, detailed drawings of which are said to have been obtained from the Soviet Union in 1989. This project illustrates India’s industrial capabilities and weaknesses. The secretive Advanced Technology Vessel (ATV) project to provide nuclear propulsion for Indian submarines has been one of the more ill-managed projects of India.

Although India has the capability of building the hull and developing or acquiring the necessary sensors, its industry has been stymied by several system integration and fabrication problems in trying to downsize a 190 MW pressurized water reactor (PWR) to fit into the space available within the submarine’s hull. The Proto-type Testing Centre (PTC) at the Indira Gandhi Centre For Atomic Research. Kalpakkam, will be used to test the submarine’s turbines and propellers. A similar facility is operational at Vishakapatnam to test the main turbines and gear box.

According to some accounts India planned to have as many as five nuclear submarines capable of carrying missiles with nuclear warheads. The Indian nuclear powered attack submarine design is said to have a 4,000-ton displacement and a single-shaft nuclear power plant of Indian origin. Once the vessel is completed, it may be equipped with Danush/Sagarika cruise missiles and an advanced sonar system. However, according to some analysts the most probable missile for the Indian submarine would be the Yahont anti-ship cruise missile designed by NPO Mashinostroyeniya.

With the participation he accomplishes of involved Russian scientists and technician in the diverse phases of the program, has possibility of that the first Indian submarine with nuclear propulsion, with 9,400 tons of displacement when submerged and 124 meters of length, can be operational in 2009, will have been launched in 2006-2007.

By 2004 it was reported that the first ATV would be launched by 2007. At that time it was reported that it would be an SSGN and displacing some 6,500 tons, with a design derivative of Russia’s Project 885 Severodvinsk-class (Yasen) SSN. The ATV multirole platform would be employed for carrying out long-distance interdiction and surveillance of both submerged targets as well as principal surface combatants. It would also facilitate Special Forces operations by covertly landing such forces ashore. The ATV pressure hull will be fabricated with the HY-80 steel obtained from Russia.

This way would have the possibility of multiple performance: it could use missiles of cruise of average reach (1,000 km), ballistic missiles of short reach (300 km), torpedoes and mines, besides participating of operations special. If it will have success in this taken over on a contract basis, will be valid to assume that the Indian Fleet will count on four to six of these submarines until the year of 2020.
