Missile destroyer INS Chennai launched

The Indian Navy launched a new warship, a missile destroyer in the Project-15 alpha class, at the Mazgaon Dock in Mumbai on Thursday.

Elizabeth Antony, wife of Defence Minister AK Antony, launched the warship.

Speaking on the occasion, Defence Minister AK Antony said that India should have indigenous warship manufacturing capability and that the country cannot depend on foreign shipyards

The Project 15 Alpha is code name for Kolkata-class destroyers that are being made in the Mazgaon dock in Mumbai.

These are the largest warships ever constructed at Mazgaon, the oldest and the most prolific of all Indian naval dockyards.

Aimed at adding a new dimension to the country's naval warfare, India has launched the indigenous warship with enhanced stealth features and land-attack capabilities.

"Project 15 A, although conceived as a follow-on of the earlier Delhi class, has major advances in its weapons and sensors and is technologically far more superior," the sources said.

The lead ship INS Kolkata and its sister ship INS Kochi have already been launched.

The Kolkata-class ships have a length of 163 mts, width of 17.4 mts and displacement of 6,800 tonnes, and will carry two helicopters on board.

The 6800 tonnes Kolkata class (Project 15-A) destroyers will incorporate Indian systems including the HUMSA-NG (Hull Mounted Sonar Array new generation), 16 Brahmos missiles, torpedos and the Nagin active towed array sonar, jointly developed by the DRDO's Naval Science and Technology Laboratory in Visakhapatnam and Bharat Electronics Limited in Bangalore.

Russia is assisting Project 15-A will assist with shafts and propellers. The propulsion package will consist of four reversible gas turbines in combined gas-and-gas configuration.

Russia will also provide the know-how for pontoon-assisted launches.

Conventionally, a ship is 'launched' into water once its hull is completed, after which the superstructure -- the upper decks and masts -- is fitted on in deeper water.

India's 3rd indigenous naval destroyer launched
CNN-IBN


Mumbai: India's third indigenous naval destroyer INS Chennai built at the Mazagaon Docks was been launched on Thursday in Mumbai.
The warship was launched by Defence Minister AK Antony's wife Elizabeth Antony.

INS Chennai has been built in Mumbai under the code name of Project 15 Alpha.
The destroyer is the third and last of the Kolkata class warships built at Mazagaon Docks and displaces more than 6,000 tonnes.
Its weaponry is entirely indigenous comprising 16 Brahmos missiles and torpedos. The warship is also equipped with the indigenous Humsa sonar and Ellora electronic warfare suite, and carries two helicopters on board.

During the launch Antony stressed on the importance of having a well protected coastline, especially in the wake of the 26/11 Mumbai terror attack.
He said there is a need to built more warships for the Navy.

"Protecting our coastline is most important after 26/11. We must defend it against all possibilities. We need to build more warships for the Navy and Coast Guard indigenously. Our defence shipyards must be able to fulfil our requirements on time and keep up quality," said Antony.

The Chief of Naval Staff Admiral Nirmal Verma was also present on the occasion.

Type 15A / Project 15A Kolkata Class Guided missile Destroyer

Project 15B Destroyer

Type 15A (Project 15A) Kolkata class guided missile destroyers are the latest stealth destroyers with land attack capability being built for the Indian Navy. The first vessel is expected to join the fleet in 2010, followed by the second vessel in 2011 and the third vessel in May 2012.

Development

The Cabinet Committee on Political Affairs (CCPA) approved construction of three more frigates as the follow on of Project 15 frigates in 1986. The Ministry sanctioned in March 1986 the construction of three frigates at a cost of Rs 360 crore at MDL. The construction of these frigates had not been initially taken up so the Navy redesigned them to make them with modem warfare capabilities. In May 2000, the government approved construction of three units of the Project 15A Bangalore Class destroyer. To be built to a modified design, construction of the P-15A 'Bangalore' Class ships could begin at MDL in 2002. Tentative delivery of the first unit was to be five years later, and the other two at 18 month intervals thereafter.

The Bangalore class used the same hull as the Delhi class, with major differences - including the weapon systems. The P15A ships were initially planned to possess enhanced stealth features and land-attack capabilities in the form of Russian-built Novator 3M54E1 'Klub' vertically launched cruise missiles. The Delhi class employed the Russian Kashmir SA-7 surface-to-air missile system and the KH-35 Uran surface-to-surface missile. The Bangalore class would employ the Israeli Barak-1 for its surface-to-air missile system and the Indian-developed BrahMos for its surface attack requirement.

The Project-15A Kolkata class [not Bangalore] ships are follow-on ships of the Project-15 destroyers, namely ships, Delhi, Mysore and Mumbai - the front line combatants of Indian Navy. The P15A destroyer possess enhanced stealth features and land-attack capabilities and add a new dimension in naval warfare for the Indian Navy. 'Kolkata' has a length of 163 meters, beam of 17.4 meters and displacement of 6,800 tons and carry two helicopters on board. Propelled by four gas turbines, the indigenously designed ship will have modern weapons and sensors, advanced action information system, total atmospheric control system and a host of other advanced features. The BrahMos cruise missile will equip all major Indian naval warships like the three under-construction Project 15A destroyers and Project 17 frigates and will be retrofitted on one existing warship each year.

The 6800t Kolkata class (Project 15A) destroyers are a state of the art follow-on of the Delhi class destroyers. The Delhi Class has acquired an almost iconic status, being one of the finest in their category. The follow-on series is more or less similar having the same propulsion with minor improvements. There will be some changes in the weapon systems, which will be mostly of Indian origin. Basically an incremental improvement on the Delhis by adding Brahmos. The design of the DDG includes a 16-cell BrahMos UVLM along with a 32-cell UVLM for the Barak-2 below the bridge, and another 32-cell UVLM for the Barak-2 aft of the helicopter deck, along with the mast-mounted EL/M-2248 MF-STAR radar.

Although conceived as follow-on to the earlier Delhi class, Project 15A ships, and the Shivaliks as well, will be technologically far superior, with major advances in weapons and sensors. More of these systems are now produced indigenously, but their delivery occasionally takes time, upsetting commissioning schedules. Overseas suppliers are not always prompt either. The Indian systems include the HUMSA-NG (Hull Mounted Sonar Array – new generation) and the Nagin active towed array sonar, jointly developed by the DRDO’s Naval Science and Technology Laboratory (NSTL) in Visakhapatnam and Bharat Electronics Ltd (BEL) in Bangalore.

India produces torpedo mounts and heavy and lightweight electrically propelled torpedoes too, as also complete electronic systems and anti-ship warfare (ASW) rocket launchers. The country is also jointly producing with Russia the PJ-10 BrahMos. This supersonic anti-ship cruise missile is now fitted on all major naval platforms as it has become the Indian Navy’s standard strike weapon. There have been times the BrahMos has needed to be retrofitted on ships after they have been launched, derailing commissioning schedules even further.

The Project 15-A is about 90 percent indigenous by cost. And the design itself is 100 per cent Indian. The three Project 15-A Kolkata-class destroyers will each cost the navy Rs 3,800 crore (US $950 million), including the cost of long-term spare parts. Three 6,250-ton destroyers, fitted with the Aegis radar and fire control system, will set Australia back by Rs 32,000 crore (US $8 billion). At about Rs 11,000 crore per destroyer, that is almost three times the cost India is paying for its Kolkata-class destroyers.

In September 2003 construction commenced on Project 15A, the Kolkata Class ships, the first of which was scheduled to enter service in 2010. By 2005 Mazagaon Dock Ltd [MDL] had started work on two Bangalore class destroyers and the work on third such ship was to begin in 2005. The first unit of the Bangalore class could be commissioned as early as 2008 if the funding stream continued unabated. Project-15A experienced delays. The lead ship, Kolkata was launched in March 2006, with the commissioning scheduled for 2010. By 2007 Project-15A was going slow due to delay in finalisation of design data and Russian weapons and sensor systems to be used on board. Russia was also late in supplying equipment like shafting and propellers. Moreover, extensive design and production rework had to be done due to a large number of changes made after production work had commenced. 'Kolkata' is the first of three ships in the class under construction at Mazagon dock and is scheduled to join the Navy in 2010. The second and third ships will follow in 2011 and 2012, respectively. The first missile destroyer of Project-15A - 'Kolkata' was launched at Mazagon dock 30 March 2006. The ship was formally launched by Mrs Roopa Byce, wife of Vice Admiral Sangram Singh Byce, Flag Officer Commanding in Chief, Western Naval Command. Chief of the Army Staff General J J Singh and a number of senior Army and Naval officers were present on the occasion.

The subsequent two sister ships were yet to be named as of early 2008. While the keel of the second was laid in October 2005 and its launch due to take place in April 2008, the lack of berthing space has delayed it to sometime in 2009, with commissioning beyond 2011. The keel of the third was yet to be laid as of early 2008, though its launch and commissioning had been unrealistically announced for 2011 and 2012.

By early 2009 INS Kolkata, the first destroyer of Project 15-A, was being kitted out for its commissioning in 2010. MDL was fighting to deliver this Rs 11,000 crore project on time. Default by a Ukrainian shipyard in delivering the propellers that drive these warships and the shafting that delivers power from the engines to the propellers was holding back completion. The first Kolkata class destroyer was to be delivered in May 2010. The next two are scheduled for delivery at one year intervals, i.e. May 2011 and May 2012, respectively.

Russia is assisting Project 15-A not only with shafting and propellers, but also the know-how for pontoon-assisted launches. Conventionally, a ship is “launched” into water once its hull is completed, after which the superstructure — the upper decks and masts that together weigh several thousand tonne — is fitted on in deeper water. The shallow water near the slipways, where warships are built, cannot accommodate fully built warships, which require a deeper draught.

Stealth destroyer ''Chennai'' launched from MDL
Mumbai | Thursday, Apr 1 2010 IST




Naval Chief Admiral Nirmal Verma today sought the defence Shipyards in the country to brace up and build vessels at a faster pace to meet the demand of the Indian Navy even as Defence Minister A K Antony underscored the need for latest armament to tackle new seaborne threat perceptions, hightened by the 26/11 attack on Mumbai.

Admiral Verma speaking at the launch of the latest stealth destroyer 'Chennai' at the Mazagon Dock Limited (MDL) here also wanted the time taken for induction of ships into the Indian navy hastened. Both the Naval Chief and Mr Antony concurred that move emphasis should be laid on building various naval ships indigenously rather than acquiring from abroad.

The 6700 tonne 'Chennai' is the third of the three destroyers built by MDL and is likely to be inducted by the Navy in 2013.

Technologically superior to the Delhi class of destroyers, the 163 m long chennai is propelled by four gas turbines and designed to achieve speeds in excess of 30 kinots.

It would advance weapons and sensors, stealth feataures, advanced action information system, and a comprehnsive auxiliary control system besides a host of other advanced features. The ship was launched at the hands of Mrs Elizabeth Antony, wife of Mr Antony.

Admiral Verma described the launch as the red letter day for the nation.

Chennai would be fitted with the indigenous supersonic BrahMos Surface to surface missile systems that would enable the ship to engage shore based and naval surface targets at long ranges, making it a lethal platform for strrike against enemy targets.

The ship's air defence capability, designed to counter the threat of enemy aircraft and anti ship cruise missiles would revolve around the vertical launch, long range surface to air missile stem which was being co developed by the Defence Research and Development Oranisation.

Mr Antony assured the defence production units in the country that the government would strengthen their hands in going in for the latest technology and also meet the deadline of the armed forces in acquiring new weaponry and systems. He said though the defence shipyards were performing well, they have to enhance their capability further to meet the stringent and timely requirement of the armed forces he said adding if necessary the government would also look to the shipyards in private sector for building naval ships. He said all the defence oriented shipyards were being modernised to enable them to take up production in a modular basis which would cut cost and time.

Great effort indeed in posting , nice presentation . Keep up
I like your Avatar also.

can you tell differences between these class15a ships to class17a ships
I mean kolkata-class vs Krivak3-class build in Russia vs Shivalik-class build in india
What info you have regarding class 15b and 17b

 

[Draft]

Off topic but.....I find Indian Navy quite receptive of Indian made products unlike Air Force and Army. Is it just me or is there anybody else too who thinks the same?

 

[ARCHON]

mean machine

 

[aimarraul]

looks good,what kind of VLS is this destroyer going to fit with?

 

[illuminatidinesh]

ooks good,what kind of VLS is this destroyer going to fit with?

Probably Hot launch system of grid type..... I think it s probably the revolver type..... There is no confirmed report.

The Krivak III class are basically the Talwar Class for the Indian Navy – quoting from wiki –

The Talwar class is a new class of frigates designed and built by Russia for the Indian Navy. The Talwar class guided missile frigates, also known as the Type 1135.6, are modified Krivak III class frigates from Russia. The Talwar Class has a displacement of 4,000 tons and speed of 30 knots and is capable of accomplishing a wide scale of missions, primarily, finding and eliminating enemy submarines and large surface ships.
Due to the use of stealth technologies and a special hull design, the resulting frigate features reduced radar cross section (RCS) as well as electromagnetic, acoustic and infrared signatures. Equipped with Russian-made sensors and weapon systems, the Talwar class frigates are modern ships with balanced capabilities, capable of countering modern Western naval assets. The Talwar Class is Indo-Russian joint production. Ships of this class have quite a few systems of Indian origin and manufacture, including their anti-submarine sensor (sonar) suite and complete communication equipment.


The Shivalik class frigates or Project 17 class frigates are multi-role frigates with stealth features being built for the Indian Navy. They are the first warships being built in India with such features. The lead vessel of the class is scheduled for commissioning in April, 2010.
The Shivalik class will be the main frigates of the Indian Navy in the first quarter of the 21st century. 3 ships of the class are being built by Mazagon Dock Limited. A total of 12 ships are planned to be built in various batches, with a second batch of four updated frigates currently in planning.


The major difference between these three is the tonnage as well as the armament they carry. The Kolkata class is generally the heaviest of them Being a dedicated guided missile destroyers, she is very heavily armed and can be considered the most dangerous. Where on the other hand the Shivalik will rely more on Stealth and the use modern warfare tactics such as the use of a 10 gigabit LAN for their internal network for faster communication. I am not an expert in Naval Warfare but I hope I answered some questions.
