According to well connected French financial newspaper La Tribune, French shipbuilder DCNS and its Indian industry partner Mazagon Docks Limited (MDL) have made an unsolicited "repeat order" offer for threeScorpene-class submarines to the Indian Navy.

Six submarines of the P75 project are being built by MDL through technology transfers from DCNS for the Indian Navy. "Kalvari", the first Scorpene class diesel-electric submarine (SSK) was launched in the water on 28th October 2015 in Mumbai. It started sea trials in May last year. The sea trials campaign went well and left Indian submariners with a very good impression. "Khanderi", the second submarine in the series, is set to be launched this month.

The repeat order proposal for three more submarines would include an Air Independent Propulsion (AIP) system developped by India's Defence Research and Development Organization (DRDO). An AIP system allows submarines to stay underwater for longer durations. The last two of the six Scorpene submarines initial order (P75 project) were set to be fitted with this DRDO AIP system but the decision was reverted late last year. According to Indian media, the DRDO missed the deadline.

Regarding the "leak" of sensitive documents issue, La Tribune's article stresses that India is now reassured over the false data leak case. India and France managed this issue by setting up a joint working group. The leaks were mainly commercial or training-related information as well as technical documents with a "restricted" classification level at most (as opposed to the much more sensitive "secret" or "top secret" levels).

During the international Seminar on "Current & Future Challenges in Design & Construction of Underwater Vehicles" held in November 2016, Indian Defense Minister Manohar Parrikkar expressed a need for 24 submarines to be built for the navy (including the 6 P75 Scorpene submarines currently on order).

In October 2014, India launched the P75I project, a follow-on to Project P75. Under this project, the Indian Navy intends to acquire 6 diesel-electric submarines with AIP for endurance and a vertical launch system (VLS) to enable them to carry multiple Brahmos supersonic cruise missiles. All six submarines are set to be constructed in Indian shipyards in accordance with the Make in India initiative of the government. The likely designs bidding for P75I are Germany's (TKMS) Type 214, Russia's (Rubin design bureau) Amur-class, Sweden's (Saab) A26 and France's (DCNS) Scorpene.

You can all be sure that if the "leaks" were so deep, Australia would never have ratified the mega deal for 12 SSK lastmonth.
And never would the USA have agreed to provide one of their finest combat mission system in a corrupt business.

It is a bad attempt to destabilization from one of the competitors of DCNS ... a German? ... I think.

TKMS has no experience in VLS. as is Saab.

Amur is a failed product. Better to take Kilo.

DCNS produce VLS for french deterrence until 45 years....

Khanderi, the second Kalvari class submarine, will be launched at the Mazagon Dock Shipbuilders Limited (MDL) here on January 12.

Union minister of state for defence Subhash Bhamre will preside over the function to initiate the launch of Khanderi (Yard 11876).

The launch will start a trail of events, which will lead to the separation of the submarine from the pontoon on which it is being assembled and its final setting afloat, an official release said.

“India is among few countries in the world which produces conventional submarines. Six submarines are being built at MDL in collaboration with M/s DCNS of France, as a part of Project 75 of Indian Navy. The first submarine of the class (Kalvari) is completing its sea trials and will be commissioned shortly into the Indian Navy,” the release said.

Indian Navy’s Submarine arm will complete 50 years on December 8 this year. Submarine Day is celebrated every year to commemorate the birth of the submarine arm with induction of the first submarine, erstwhile INS Kalvari, into the Indian Navy on December 8, 1967, it said.

India joined the exclusive group of submarine constructing nations on February 7, 1992, with the commissioning of the first Indian-built submarine, INS Shalki.

MDL built this submarine and went on to commission another submarine, INS Shankul on May 28, 1994. These submarines are still in service today.

Khanderi is named after the Island fort of Maratha forces, which played a vital role in ensuring their supremacy at sea in the late 17th century, the release said.

The state-of-the-art features of this Scorpene class submarine includes superior stealth and the ability to launch a crippling attack on the enemy using precision guided weapons.

The attack can be launched with torpedoes, as well as tube-launched anti-ship missiles, whilst underwater or on surface. The Stealth features will give it an invulnerability, unmatched by many submarines.

The submarine is designed to operate in all theatres, including the tropics. All means and communications are provided to ensure interoperability with other components of a Naval Task Force.

It can undertake multifarious types of missions typically undertaken by any modern submarine i.e anti-surface warfare, anti-submarine warfare, intelligence gathering, mine laying, area surveillance etc.

It is built according to the principle of Modular Construction, which involves dividing the submarine into a number of sections and outfitting them concurrently.

Indian govt. should scrap P75I and should immediately order 6 more scorpenes with DRDO AIP and 4VLS tubes and get done with it. This will bring in faster submarines, amortize line bringing down costs, commonality benefits, etc. Later upgrade current scorpenes with DRDO AIP and VLS . Buy out 6 kilos with AIP from Russia only if needed as urgency or directly move to 12 to 18 SSN (preferably) if possible by 2035.

Looks like two floor design..What machinery is packed in lower deck...why it takes too much of time to build these things..we can split different sections to different shipyards and assemble right?

Khanderi launched in water: 10 interesting features

Khanderi, the second Kalvari class Scorpene submarine, was launched into water - or 'undocked' - by the Union minister of state for defence Subhash Bhamre at the Mazagon Dock Limited (MDL) today. The submarine will undergo rigorous tests and trials on the surface and underwater before it is commissioned into the Indian Navy as "INS Khanderi" at the end of the year in December.

Here's a look at some of its special features:
1.

The Khanderi is armed with torpedoes, as well as tube-launched anti-ship missiles, whilst underwater or on surface.. These missiles are capable of being launched from underwater or from the surface. Khanderi can also run in extreme temperatures, giving it an invulnerability unmatched by many other similar crafts.

2.
It can undertake various types of missions which are typically undertaken by any modern submarine, like anti-surface warfare, anti-submarine warfare, intelligence gathering, mine laying and area surveillance.

3.
Khanderi is named after the island fort of Maratha forces, which played a vital role in ensuring their supremacy at sea in the late 17th century.

4.
The state-of-the-art features of the Scorpene include superior stealth and the ability to launch crippling attacks on the enemy using precision-guided weapons.

5.
The submarine is built in India by Mazagon Dock Limited under a transfer-of-technology agreement with the French naval defence group DCNS.

6.
The Khanderi has been built using the "modular construction" technique. That means its manufacture was divided into several sections and they were outfitted concurrently. This is a complex task involving laying kms upon kms of cabling and piping in extremely congested compartments.

7.
The most important safety milestone, called "vacuum testing", was completed in the very first attempt and on a single day, January 5. That matched the record of the earlier Scorpene Kalvari, which also completed these tests in one shot - a feat unmatched in submarine construction history.

8.
The submarine is powered by a diesel-electric engine. That means that Khandari won't be able to remain submerged for long durations and will have to resurface to recharge its batteries using a snorkelling pipe.

9.
Until December, the submarine will undergo rigorous tests and trials in harbour and at sea, and on surface and underwater, so each system is tested to its fullest capacity, before it is commissioned into the Indian Navy as "INS Khanderi".

10.
As per Indian Navy tradition, ships and submarines of the Navy are brought alive again after decommissioning. The first ship "Khanderi" was commissioned on December 6, 1968 and decommissioned in October 1989, before it was "reincarnated" by MDL as a powerful predator for the deep waters, to guard the vast maritime interests and territories of Ind.

Looks like two floor design..What machinery is packed in lower deck...why it takes too much of time to build these things..we can split different sections to different shipyards and assemble right?

Yes, it's possible.
The german worked that way during WW2 to built typ XXI subs.

Scorpene in India takes time, because of some problem during the ToT (welding tech with Mazagon for exemple). But now it seems the rythm of production is quite good.
