India's First Scorpène-Class Diesel-Electric Attack Submarine INS Kalvari Rolled Out!

I am pulling Aby's leg. Of course there's nothing wrong with calling him sir. :p:

More on your question, consider the fact that the Akula-2's appearance created enough ruckus to get the US Congress to officially sit down on the topic, they found that the Nerpa and its brethren were quieter than the improved Los Angeles class subs (something that a certain Chinese poster on this thread should take cognizance of). Matching that will take time.

Baraa hiii tuuu hai; na sallam na dua aur straight Akula parrr ! :tsk:

results are yet to come boy.....:azn:, how about doing engineering??? IIT mains???form???:partay:

I am confident that I would pass the boards - Itne bure din nahi aae abhi - :D - I took JEE Mains on 4th - Attempted 50 questions - Got some 30 right - so near about 110 marks obtained. Looking forward to state engineering examination and admission to central universities like Jamia - hope I will get an admission into some or the other government engineering college. :bounce:

my score was better than yours:p:, 138 marks but due to low percentage in my CBSE, i wasnt able to clear JEE advance:(, i had attained 72.6 percent, i hate chemistry:angry:.........but now i'am sailing like a submarine:partay:............flawless engineering campaign.......i'am from Mumbai university college.....:yay:

The question is not who selected Scorpene, but why? The German U214 offer, was reportedly cheaper, included AIP and might had been easier, since we have similar subs in the fleet and produced them under licence in the past. But would we have got the same level of ToT? Doubtful, since the French are known to be more open to ToT of critical techs. Were techs for our nuclear sub development part of the deal? Could be. Was the fact that the French allowed DRDO to integrate an own AIP a factor? Possible, since the French AIP wasn't ready back then, it might had opened an option to negotiate in favour for the DRDO system.
So while it's bad for the operational side of IN, the deal might had some important points for the industry. The only sad thing is, that we waste all the know how we gained so, if we don't go for a follow Scorpene order or an own SSK development and may start from scratch again, by having to set up infrastructure and a know how base at a new ship yard, possibly even of a different type of sub.

plus we have a 'history' with that German company. It really is politically volatile to associate with them.

Great! BTW Mumbai University admits through JEE Mains?

Iam quite amazed to see such young boys intrested in military and political affairs......i would feel proud if some day one of our internet buddy joins our military and makes us proud......wish u all good luck....:-)

Yeah. Really heartwarming to see that. Little bro, if you keep your eyes open there are lots of opportunities to learn in this forum. Nice to see couple of young lads contributing to threads without any trolling.

You and @Chanakya's_Chant have a lot of opportunities to join three branches after completion of Your engineering degrees. Me personally, I would like to join Navy non technical branch. Missed last recruitment window as I didnot get my final marksheet on time. Lets hope better luck this time around. :cheers:

I just passed my Class XII Boards! :cheesy: What are you doing? :cheers:

Completed MBA in Finance & Marketing Mgnt in June, & after ditching a few marketing jobs I am currently preparing for various competative exams held by likess of Oil, ONGC etc. But main goal is to crack SBI PO which I missed out last time even after scoring a lot more than minimum qualifying marks. Cleared IBPS RRB & currently waiting for the Interview phase.

Kalvari adds to Indian Navy’s underwater stealth
CB4cjNWUoAAyuo_.jpg:large

Kalvari, first of the Indian Navy’s Scorpene class stealth submarines being built under the Project 75, achieved a major milestone last week with her ‘undocking’ at the Mazagon Dock in Mumbai. Undocked by the defence minister Manohar Parrikar, it is the first of the six Scorpene submarines in which DCNS of France is a collaborator with Mazagon Dock Ltd (MDL) as the builder and is the country’s first indigenous submarine. More than 30 Indian companies were involved in the indigenisation process of these submarines.

With a name steeped in the long and glorious tradition of its illustrious predecessor, an erstwhile Russian ‘Foxtrot’ class submarine, Kalvari, upon its scheduled commissioning in 2016, is expected to lend an enormous fillip to theIndian Navy’s underwater capability. The remaining five boats of the Project 75 would be delivered by the yard to the Navy by 2020 and would form the core of the Navy’s submarine arm for the next two decades.

This development puts India in a better better position to fulfill its requirement of submarines to protect its sea waters by 2022. The Scorpene is part of the ambitious Project 75 of Indian Navy’s submarine programme, undertaken with French collaboration, which will include six such vessels joining the fleet over the next few years. The state-of-the-art features of the Scorpene include superior stealth and ability to launch a crippling attack on the enemy using precision guided weapons. The attack can be launched with torpedoes, as well as tubelaunched anti-ship missiles, while underwater or on surface.

Kalvari is designed to operate in all theatres including the tropics. All means andcommunications are provided to ensure interoperability with other components of a naval task force. It can undertake multifarious warfare, anti-submarine warfare, intelligence gathering, area surveillance etc. Built from special steelcapable of withstanding high yield stress and having high tensile strength, it can withstand high hydrostatic force and enabling it to dive deeper. It is equipped with Weapons Launching tubes (WLT) and can carry weapons on board which can be easily reloaded at sea.

At present, Indian Navy has 14 conventional diesel-electric powered submarines which include 10 Russian Kilo Class and four German HDW class vessels. These submarines have diesel propulsion and an additional air-independent propulsion. Interestingly, following a naval tradition, in which warships never die, the newdiesel-electric submarines will be named as per the old Foxtrot class boats, which were decommissioned decades ago. They were the first submarines of the Navy.

Since there have been several accidents on the naval vessels, the Defence Research and Development Organisation (DRDO) has decided to include mechanisms in these submarines to ensure safety. The agency is said to be developing a system to carry out structured health monitoring of the under-development nuclear submarines and future conventional submarines of the Navy.

The project to build the Scorpene submarines was awarded to DCNS in October 2005 to build six Franco-Spanish Scorpene-class diesel attack submarines at the Mazagon Dock in Mumbai. The deal involved extensive technology transfer agreements.

In what is considered to be a major breakthrough by the DRDO, towards achieving self reliance in critical underwater technology, defence scientists have developed the air independence propulsion (AIP) system which is expected to help Naval submarines remain submerged for much longer, reducing the need for the vessels to surface for breathing air. The conventional submarines of the Indian Navy fleet were lacking this critical technology making them vulnerable as they need to surface at regular interval to suck the air (oxygen) which is required to keep submarines batteries running.

On the other hand, submarines of the arch rival Pakistani Navy, mostly procured from France, are equipped with the AIP. The AIP would be in form of a fuel cell which will replace the diesel component of the conventional submarines. Thesystem would be put to test on Scorpene submarines being built in Mazagon Dock,Mumbai, with the help of France. “Last two of the six Scorpene submarine will be equipped with indigenous AIP system,” the scientists said, adding that next six submarines to be built in Indian shipyard under technology transfer from aforeign vendor shall also have this critical component. AIP turns a conventional submarine into a vessel which is very similar to nuclear powered one, as they also need not to surface to breathe oxygen. The Indian defence scientists startedworking on the project four years ago, which has entered into final stage now.

The Defence Acquisition Council, headed by Arun Jaitley while clearing Project-75I under which next six submarine are to be built through “Make in India” route, has also given an in-principle approval that indigenous AIP system will be fitted on these future vessels.

In June 2011, DCNS India signed a contract with Flash Forge India, under the Scorpene submarines programme (P75), to manufacture equipments which were to be installed onboard the Scorpenes. The Factory Acceptance Test (FAT) for the first locally made Scorpene equipment was successfully performed at Flash Forge premises in Visakhapatnam in January 2012.
