Both are different types of ships suitable for different operations there is no better ship in war both have their roles to play, moreover there are further sub-classes of air-defence destroyers & anti-shipping destroyers, frigates similarly can be further calssified into ASW frigates, patrol frigates and many other options, the main difference is these two ship classes is in displacement ;while a typical destroyer is between 5000 - 8000tonnes displacement, the displacement of the typical frigate varies between 2500-4000tonnes.

Patil to take to sea on INS Viraat
TNN 11 December 2009, 02:02am ISTText Size:|Topics:pratibha Patil
warship
Sukhoi

NEW DELHI: Taking another leaf out of her predecessor A P J Abdul Kalam's book, President Pratibha Patil is now all set to sail on a naval warship after taking to the skies in a Sukhoi-30MKI fighter jet last month.

Sources on Thursday said Patil was likely to sail in India's solitary aircraft carrier INS Viraat on December 23. "There will be a fleet review as well as live firing of missile systems during the `President's day at sea','' said an official.

Much as her flight on the Sukhoi raised questions about why women pilots were still not allowed to fly fighters in IAF, Patil's sojourn on INS Viraat will also underline the reality that women officers are banned from serving on operational warships.

The military top brass says there are `operational, practical and cultural problems' in allowing women to take part in `combat roles' by flying fighters or serving in infantry or on board warships.

Being the first-ever woman supreme commander of the armed forces certainly has its privileges. Kalam, the father of the Indian missile programme, had grabbed nation-wide eyeballs by first undertaking a sortie in a Kilo-class submarine in February 2006, and then following it with one on a Sukhoi in June 2006.

Following in his footsteps, Patil had flown in the twin-seater Sukhoi, the country's most potent supersonic fighter, at the Lohegaon airbase in Pune on November 25.

And now, instead of taking a dive in a submarine, she will take to the high seas on the 28,000-tonne INS Viraat, which after a 18-month-long comprehensive refit to increase its longevity as well as upgrade its weapon and sensor packages, is fully back in action now.

But, as earlier reported by TOI, the 50-year-old INS Viraat is fast running out of the Sea Harrier jump-jets that take off from its angled ski-jump and land vertically on its deck. Navy had inducted 30 of the British-origin Sea Harriers but is left with only 11, with the rest being lost in accidents since the mid-1980s.

Navy to build four amphibious warships



Aiming at adding more teeth to its amphibious warfare capabilities, the Navy is planning to build four Landing Platform Docks (LPD) to join the fleet, alongside INS Jalashwa, a US warship bought by India in 2007.

The Navy is already in the process of getting the design for the LPDs ready in the next year or two and will move the government for sanction to build these warships.

“The plan is to add four more LPDs to the fleet and these would operate alongside INS Jalashwa, the only LPD currently in service,” a senior Navy officer told PTI here on Sunday.

“In the coming year or two, we are going to finalise the design for the LPD, which is somewhat akin to INS Jalashwa.

The government sanction for building these ships would be obtained next,” he said.

INS Jalashwa - a Sanskrit name for Hippopotamus - is a replenishment and amphibious warfare ship with capacity to embark, transport and land a 1,000-men battalion along with equipment and tanks to support operations on enemy shores.

Being the second largest ship in the Navy inventory after aircraft carrier INS Viraat, Jalashwa is also capable of undertaking maritime surveillance, special operations, search and rescue, medical support as well as humanitarian aid.

Jalashwa was originally commissioned in the US Navy as USS Trenton and had served for 36 years when India bought it for USD 48.44 million and commissioned it in its Navy in June 2007.

After a refit programme at Norfolk, US, Jalashwa joined the Indian Navy service late in 2007 and is based under the Eastern Naval Command in Visakhapatnam.

Jalashwa became the first ship the US transferred to India. It is also the first LPD in the Indian Navy service.

“The need for such a landing transport amphibious warship was felt in December 2004 when Tsunami waves hit Indian coast including the Andaman and Nicobar Islands and Southeast Asia,” the officer said.

India had rushed its warships with medical aid and food to the countries hit by Tsunami, but an LPD, which could be converted into a multi-bed hospital, would have made a difference, they said.

“But more than that, LPDs provide the Navy strategic reach to operate far away from Indian shores and support amphibious warfare,” they added.

Jalashwa also carries four mechanised landing craft and eight landing assault craft, which could be launched by flooding the ship’s well deck, a speciality of LPDs. These craft could reach enemy shores and dock to deliver infantry and mechanised troops, tanks and equipment.

It also has a flight deck for operating four medium helicopters simultaneously, apart from operating Vertical Take-Off and Landing (VTOL) aircraft such as Sea Harriers, which the Navy possesses, in special circumstances.

This is a great step by the IN. After gaining experience on the INS Jalshawa they are going ahead and designing their own ships. This will go a long way to project the might of the Indian armed forces.

By the way I just remembered that GRSE has built 6 Tank Landing ships for the IN.
Could somebody please elaborate on the Differences between a TLS and a LDP.

Arakonam to be vital hub for Navy

CHENNAI: Arakkonam naval air station, 70 km west of Chennai, is all set to be a hub for modern maritime reconnaissance with the Indian Navy planning to station eight long-range maritime reconnaissance aircraft Boeing P81 to be bought from the US aircraft manufacturer

"The aircraft will be capable of long-range maritime patrol, anti-submarine warfare, anti surface warfare, intelligence gathering and search and rescue missions. It will be fitted with the best available sensors in the market," said assistant chief of naval staff (Air) rear admiral S M Vadgaokar, at the passing out of helicopter pilots from Helicopter Training School at INS Rajali in Arakonam on Saturday.

India signed a $2.1 billion contract with Boeing for acquiring these aircraft in January 2009. They will replace the eight Russian Tupolev-142M turboprops.

"Eight aircraft are included in the contract. But, we have an option to buy four more which may be bought from another manufacturer. Delivery of the aircraft will start by end of 2012. The last aircraft will come in 2015," Vadgaokar said.

The P-81 planes with an operating range of 600 nautical miles are expected to help plug the existing voids in Navy's maritime capabilities. The aircraft will be customised for India and will be based on the Boeing 737 -800 commercial airliner.

"The first few pilots will be trained abroad with Boeing. India has expertise in piloting these planes. Many private commercial airlines have these B737-800 aircraft," he added.

Fourteen pilots from Indian Navy and two pilots from Indian Coast Guard have passed out in the 73rd Helicopter Conversion Course on Saturday.

Navy would need around 150 pilots because it was planning to replace its multi-use helicopters by inducting 100 new helicopters for ships, he said, and added that the need for more pilots could be filled in two to three years. "The navy will induct a large fleet of aircraft -- 200 helicopters, 30 medium-range maritime reconnaissance aircraft, 30 multi-role aircraft, 14 unmanned aerial vehicles and 135 fighter aircraft -- in the coming years as part of the maritime capability perspective plan drawn up till 2022."

Vadgaokar said there was no attrition of pilots in the Indian Navy. "Many move out when they reach a seniority after which they may not be able to carry on as operational pilots." Lieutenant A Garud won the best all-round trainee pilot Governor of Kerala rolling trophy while sub lieutenant K Banerjee came first in merit in flying.

Indian Navy test fires Dhanush missile

BY : ANI

‘Dhanush’, the naval version of India’s indigenously developed surface-to-surface Prithvi missile system was test fired from a naval ship about 40 nautical miles from here inside the Bay of Bengal today.
A naval team and the scientists of the DRDO jointly conducted the mission, claimed an official from the Department of Defence.
The missile was flight tested from a naval ship in the Bay of Bengal at about 11:30 A.M, according to Defence sources.
Dhanush missile is capable of carrying both conventional and nuclear warheads. It is a single stage missile with liquid propellant and can hit both sea as well as shore based targets of 350 km range with 500kg payload.
The missile in its initial test of development stage on April 11, 2000 had failed due to some technical snags developed during the blast-off phase. But, in it’s range and pay load capabilities the missile was a success.
The last trial of Dhanush missile was successfully conducted on March 30,2007 from a naval ship off Orissa coast.

Could somebody please elaborate on the Differences between a TLS and a LDP.
There is one primary difference between LPD's (Landing platform docks) and LST'S(Landing ship tank).

typical LST disembarking tanks

A LST DOES NOT carry any landing craft on board , this type of bvessel is designed to be able to beach itself on an enemy shore, open it's stern doors and let men and vehicles out.


Cutaway illustration of the U.S. Navy's San Antonio-class amphibious transport dock ship (LPD). The amphibious transports are used to transport and land Marines, their equipment, and supplies by embarked air cushion or conventional landing craft or amphibious vehicles, augmented by helicopters or vertical take off and landing aircraft in amphibious assault, special operations, or expeditionary warfare missions.

A LPD does not come close to any enemy shore .it carries landing craft whithin it's cavernous belly and uses these to transoprt men and material onto an enemy shore.A LPD serves primarly as a floating base from where boats and helicopters can be dispatched to pick up or drop off men and material on enemy shores.one more difference would be displacment while the typical LST is between 3000 to 5000 tonnes in displacement the typical LPD displaces well above 15,000 tonnes.



Coming back to the issue on hand, this sis a very welcome development and it shows the indian navy's commitment to building ships in india, the LPD's shall help us to maintain a good presence in all humanitarian operations while also serving as an effective platform from which amphibious assaults acna be launched,

just one thing remains the indian navy should now look at LHD's as well.
just look at the impressive formation below

Hindustan Shipyard Ltd likely to be transferred to Defence Ministry

Last Updated: Dec 14, 2009
Hindustan Shipyard Ltd, Visakhapatnam.​



NEW DELHI (BNS): The State-owned Hindustan Shipyard Limited (HSL), which is currently being used by the Shipping Ministry to build ships, could be used for constructing nuclear submarines after it is transferred to the Defence Ministry.

The Union Cabinet, which has received a letter from the Shipping Ministry in this regard, is expected to consider the proposal soon, media reports here said.

Negotiations were going on between the two ministries for quite some time to transfer the shipyard to the Defence Ministry for strategic purposes.

Besides building around 150 ships and repairing another 1800, Visakhapatnam-based HSL has also undertaken naval repair works.

As Indian Navy plans to induct a fleet of nuclear submarines in its arsenal in the coming years, the HSL would be of critical importance for constructing the subs.

India: Global hub for warship-building

BY: Ajai Shukla / Business-standard
Strategic circles are abuzz with rumours that the United Kingdom will soon offer India one of the new-generation aircraft carriers that it is constructing, since they are turning out too expensive for the Royal Navy to afford. Interestingly, India will almost certainly turn down the offer.The Royal Navy had planned to build two Carrier Vessels Future (CVFs): the 65,000 tonne HMS Queen Elizabeth and HMS Prince of Wales. With the budgeted price of US $6.4 billion (Rs 30,000 crore) for the pair, now apparently the cost of each, building a third and selling it abroad is an option being considered to reduce the unit price. But, in contrast to this exorbitant price, the cost of India’s 44,000 tonne Indigenous Aircraft Carrier (IAC), under construction at Cochin Shipyard Limited (CSL), is barely a third of the Queen Elizabeth. And the Indian Navy’s next IAC, a 60,000 tonne behemoth like the Queen Elizabeth, will cost less than half its British counterpart.
In the gloomy framework of Indian defence production, warship-building has emerged as a silver lining. The Kolkata class destroyers, being built at Mazagon Dock Ltd, Mumbai, will cost the navy Rs 3,800 crore each, one-third the global price for comparative warships. The INS Shivalik, now completing sea trials, is a world-class frigate built at Indian prices. Earlier this year, addressing an industries body, the Indian Navy’s chief designer, Rear Admiral MK Badhwar, called for making India a global hub for building warships.
While his appeal might have been tinged with strategic motivation — a larger warship industry would bring down unit prices, providing the navy with even more bang for the buck — there is little doubt that shipbuilders would profit more from crafting warships than from slapping together merchant vessels. India has developed the capabilities, including, crucially, the design expertise, to produce world-class warships. But the defence shipyards do not have the capacity to meet even the Indian Navy’s needs; playing the international warship market needs clear-sighted government intervention to synergise the working of public and private shipbuilders.
Building a merchant ship is a relatively cheap and simple process, from design to outfitting. Essentially, it involves welding together a hull (often from imported steel) and then installing imported systems such as engines, radars, the steering, navigation and communications systems, and some specialist systems, e.g. for cargo handling. Imported components form the bulk of the cost, with little value addition within the shipyard. A commercial shipyard’s business plan revolves around bulk manufacture, compensating for the small profit margins by churning out as many ships as possible.
Creating a warship is infinitely more complex, and expensive. The design process is critical, with complex software shaping the “stealthiest” possible ship, virtually undetectable to an enemy. Next, a host of sensors and weapons must be accommodated to deal with different threats: enemy ships, submarines, aircraft and incoming missiles. Harmonising their different frequencies, and canalising information and weapons control into a single command centre, involves weaving an elaborate electronic tapestry.
Actually building the warship is a labour-intensive task, which involves painstakingly duplicating key systems so that the vessel can sail and fight even with one side blown out by the enemy. More than 400 kilometres of wiring must be laid out inside, all of it marked and accessible to permit repair and maintenance. A modern frigate has 25 kilometres of pipelines, built from 10,000 separate pieces of piping.
All this generates many jobs. An army of skilled craftsmen, many more than in merchant shipbuilding, does most of this work manually, through an elaborate eco-system of 100-200 private firms feeding into each warship. And these numbers are growing as defence shipyards increasingly outsource, using their own employees only for core activities like hull fabrication; fitting propulsion equipment; and installing weapon systems and sensors.
In this manpower-intensive field, India enjoys obvious advantages over the European warship builders that rule the market. These advantages are far less pronounced in merchant shipbuilding, where Korean and Chinese shipyards are turbocharged by a combination of inexpensive labour, indirect subsidies, and unflinching government support.
What makes India a potential powerhouse in warship-building is not so much its labour-cost advantage as a strong design capability that the navy has carefully nurtured since 1954, when the Directorate General of Naval Design first took shape. The importance of design capability has been amply illustrated in the bloated CVF programme. The UK, having wound up its naval design bureau, has already paid over a billion dollars to private companies to design the aircraft carrier. And with every minor redesign, not unusual while building a new warship, the design bill and the programme cost goes higher.
India has everything it takes to be a warship-building superpower: the springboard of design expertise; cheap and skilled labour; and mounting experience in building successful warships. What it lacks is capacity, which the government can augment with the help of private shipyards. This will significantly augment private shipyard revenue, boost defence exports, and provide the government with another strategic tool for furthering its interests in the Indian Ocean region.

India will get Gorshkov in good shape: Russia

BY : ANI
Following India’s announcement, Russia too has confirmed that problems relating to the price of the aircraft carrier Admiral Gorshkov have been sorted out, and that the aircraft will be delivered to India in a good shape. Talking to journalists in New Delhi , new Russian envoy Alexander Kadakin said: “The pricing talks are successful and are sorted out. Gorshkov will be supplied to India in a very good shape as razor edge technology as India wants.”
The Russian envoy further said: “We are building a new heart into a middle-aged gentleman Gorshkov, which will be called VikramAditya.”
The pricing of the Admiral Gorshkov has been a contentious issue in the India-Russia strategic relationship for almost six years.
A deal for purchasing the ship was signed in January 2004. The original price was pegged at $974 million, but in November 2007, Russia asked India to pay $1.2 billion, and this year, pushed it up to $2.2 billion.
The eventual cost was pegged at a whopping $2.9 billion, which was almost three times the original cost.
Refusing to divulge the final price at which the deal has been struck, Ambassador Kadakin said unnecessary hype has been created over the deal.
Speculation suggests that the final price will be settled at $2.5 billion.
The price issue is believed to have been resolved during Prime Minister Manmohan Singh’s recent visit to Moscow
Both countries signed seven agreements, including a historic broad-based umbrella agreement on the peaceful use of nuclear energy.
According to Ambassador Kadakin, Russia will also supply a new batch of Sukhois. There was also progress on a probable purchase of medium-range transport planes, he added.

when 26/11 happened, MARCOS were deployed in the taj. inspite of not knowing the sketch (sad) of the taj design, they held the terrorists at bay saving many lives and at times came face to face with them but the smoke around clouded identification.
if not for them, even NSG would have had a horrible time when they took over. sad they never get the credit they deserve post 26/11.
