Stealth warship INS Satpura joins navy

Ajai Shukla / Mumbai August 21, 2011, 0:01 IST

In a centuries-old naval ritual in Mumbai on Saturday, navy chief Admiral Nirmal Verma commissioned into active service Indian Naval Ship (INS) Satpura.

“I wish the crew fair winds and following seas”, Verma intoned, in the traditional naval goodwill message, before raising the Indian flag on the Satpura’s helicopter deck and unveiling the ships plaque. The band struck up the national anthem, the tricolour was raised on the helicopter deck and INS Satpura became the 140th warship of the Indian Navy.

The INS Satpura, which follows the INS Shivalik into service, is the second of three Project 17 stealth frigates that are being built by Mazagon Dock Ltd, Mumbai. It will be followed by INS Sahyadri early next year. These three “state-of-the-art surface combatants” as Verma called them — trace their design ancestry to three Talwar-class frigates that Russia built for the navy a decade ago. However the Shivalik-class, as INS Shivalik, Satpura and Sahyadri are classified (after the first vessel in the series), are significantly heavier than the 4,100-tonne Talwar-class frigates, giving them the capability to absorb, as well as deliver, heavier blows in battle.

Officially termed a guided-missile frigate, the Satpura weighs in at a muscular 6,200 tonnes. Frigates typically weigh 4,500-6,500 tonnes; the next-higher class of warships, called destroyers, begin at about 7,000 tonnes. The Satpura carries 24 Russian Klub missiles, which can hit ground targets more than two hundred kilometres away with pinpoint precision. The Indian Navy would have liked the Satpura to carry the more capable and lethal Brahmos missile, but that is too heavy for the frigate. Only the Indian Navy’s destroyers are currently armed with the Brahmos.

The Satpura is also equipped with the Israeli Barak air defence system, to ward off enemy aircraft and missiles. It has torpedoes to deal with enemy submarines, as well as an RB-6,000 multi-barrelled depth charge launcher. Posted on board the Satpura is a tiny aviation unit, with hangars and facilities for two Sea King, or indigenous Dhruv helicopters.

Driving this 142 metre-long warship through the water are two French Pielstick diesel engines. In addition, there are two General Electric LM-2500 gas turbines. This provides the advantage of fuel-efficient operation in the normal course, using the Pielstick diesels, while the gas turbines take over when bursts of speed are required, especially in battle. This is known as CODOG (combined diesel or gas) configuration.

But the Satpura’s key advantage is stealth. Its design reduces the vessel’s radar, infrared, electronic, acoustic and visual signatures, making it difficult for the enemy to detect it. The design skills needed for building stealth vessels like the Satpura have been honed by Indian shipyards over time, and are reaching their finest in Project 28, a line-up for ultra-stealthy, anti-submarine corvettes that are being built at Garden Reach Shipbuilders and Engineers, Kolkata. Stealth will also form an important component of the seven Project 17A frigates that will start being built next year as the the navy’s next line of frigates.

Along with satisfaction at the Satpura’s world-class capabilities, the Ministry of Defence (MoD) remains concerned over the high level of imported components in these warships. According to the official navy figures requested by Business Standard, the total cost of Project 17A (i.e. the cost of three Shivalik-class frigates) will be Rs 7,883 crore. Of this, Rs 2,710 crore have been spent on foreign equipment, that includes the on-board weapons, sensors and radars, engines, transmission, etc.

During the commissioning, the naval chief admitted the Satpura’s indigenous component amounted to 60 per cent. Much of that amount, however, goes towards the cost of labour etc. The high-tech equipment remains mainly imported.

Notwithstanding that, the navy justifiably claims credit for indigenising the crucial dimensions of design and integration. Vice Admiral Ganesh Mahadevan, the navy’s Chief of Materials, claims that indigenisation will rise dramatically in the next two lines of warships that are coming on stream next year, i.e. in Project 15B (four destroyers) and Project 1A (seven frigates).

An important driver in lowering the cost of imported equipment is the agreement with Essar Steel for manufacturing warship-grade steel. So far, owing to SAIL’s refusal to engage in the complex manufacture of the specialised metal, which the dockyards require in relatively small and commercially unviable quantities, shipyards were left with no option but to import from Russia. Now, Essar Steel will be manufacturing the few thousands of tonnes of warship grade steel that will be needed for Projects 15B and Project 17A.

It doesn’t look like anything close to stealthy.

Do Indian warships come pre-rusted?

It looks decent to me. Seems like there should be some small caliber guns in a few locations to deal with rif-raff.

I bet if you enter that enclosed area you would immediately smell saffron and curry cooking.

The stern looks like a good place to troll for Somalis.

How is a missile too “heavy” for a 6000 ton vessel?

Does that just mean it won’t fit in the launcher?

All the stealth talk is probably for domestic consumption, for the peasants to feel proud that the gubmint is making progress on the defence front.

The Bramhos is about twice as heavy as a Tomahawk, the Klub only 50% heavier

However I expect like

The Satpura carries 24 Russian Klub missiles
it is what is known as "a journalistic mistake"

The missles are in a 8 cell silo farm on the foredeck beween the SAM laucher and the ASW RBU launchers

All sources say the cells can hold either Klub or Bramhos

The so called peasants country are now churning out CEO’s everyday.Anyway we are proud that our country can make these kinda stealthy frigates in home.
Btw Stealthy means reduction in IR SIGN,difficult to detect via sonar or radar and ultra modern electronics and weapon system on board.
Stealty doesn’t mean invisible but difficult to detect compare to other frigate.

It has more radar and IR reduction measures than most frigatess of its size. Of course, it’s not a dedicated stealth ship like the Swedish Visby class which is comparatively underarmed.

I know what stealthy means. And the term "peasants" is a sarcastic reference of how the political elite class view the regular people.

You don't need to harp on what Indians are capable of doing... such as "churning out CEO's". It makes you look like you have a chip on your shoulders and something to prove to others who you feel think less of you. Anybody who is somewhat well read, know that Indians are successful in several areas including the business world.

The only one here who seem to be having a chip on his shoulder here is you. Regardless of your condescension and what you think of Indian peasants, gubmint and domestic consumption, fact is this ship is fairly stealthy for her size, the firepower she is carrying and given this is India’s first attempt at building stealthy ship with indigenous technology.
