Undereater Drones can also be used. a small drone will come up, receive signals and will transfer the message to the submarine. No need to expose the whole big SUB for communication.

SSBN will provide us the facility to fire missile from our place of choice as per the mission requirements.
Say if you want to fire the missile on CHINA you will be able to fire it from Indian ocean, bay of bengal, Arabian sea, Pacific ocean, south china sea etc etc from anywhere.... And China will be having no intel about it till the missile is being already launched.

At Mazagon Dock, another stealth sub Karanj readies for trials
Inside the cramped Scorpene class submarine ‘Karanj’ moored at Mazagon shipyard in Mumbai, technicians are busy preparing for sea trials ahead of delivery to the Indian Navy.
‘Karanj’ is the third in a series of six Scorpene submarines being built at the state-run Mazagon Dock Shipbuilders , India’s only submarine builder, with technology from French group Naval.
The first submarine ‘INS Kalvari’ was commissioned into the Navy on December 14, 2017, while the second ‘Khanderi’ will be added by the end of the year.
The fourth Scorpene ‘Vela’ has completed the ‘boot together’ and is in an advanced stage of outfitting. The remaining two are in various stages of outfitting at the fabrication facility.
In the normal course, it would have been impossible for an outsider to take a tour of Mazagon, let alone go inside a submarine. But a group of 25 journalists got the privilege as Mazagon Dock braces for a share-sale through an IPO later this month.
Priciest part
Mazagon’s submarine building capabilities is the priciest part of the value-proposition it is holding out to prospective shareholders.
Commander V Puranik, a general manager at Mazagon Dock, showed some of the basics including design, assembly, the state-of-the art platform.
Scorpene is one of the most sophisticated submarines, capable of undertaking multifarious missions including anti-surface ship warfare, anti-submarine warfare, intelligence gathering, mine laying, and area surveillance. Its stealth capability gives it an invulnerability and the ability to launch a crippling attack using various precision-guided weapons.
“A submarine is a very potent weapon; it makes a huge difference in the geostrategic balance,” saidRajiv Lath, Director, submarine and heavy engineering at Mazagon Dock.
Mazagon Dock can build 11 submarines at a time. At the huge fabrication unit, the last two parts of Scorpene submarines 5 and 6 are being constructed. This work will be completed over the next three months.
The Scorpene project is the first of its kind where all the contracted submarines are built from scratch in India. In all the previous submarine programmes, the first few units were built abroad and the remaining in India.
“We will forget all that if we don’t get any more projects. By 2022, the last of the submarines will be delivered to the Navy. And, by 2025, the stealth frigates and destroyers will also be delivered. There is no visibility yet on further ordering,” he said.
Yet, it is hopeful.
The Navy plans to raise its fleet strength to 200 ships by 2022; so, there will be a large number of ships on order.
“If Navy wants a destroyer, they don’t have anybody else, be it open tender, strategic partnership, anything. If Navy wants submarines, do they have any other place to go?” asked Lath.
The P75 (I) orders for six submarines worth an estimated Rs 50,000 crore will come sooner or later, he signs off.

We now have a ₹53,000-crore order book, says MDL CMD
Commodore Rakesh Anand, CMD, Mazagon Dock and Shipbuilders Limited (MDL) explains the reasons behind the ₹3,000-crore cost overrun and a delay of six years in delivering six submarines to the Indian Navy. Edited excerpts:
Mazagon Dock has rich history. Can you throw some light on how it came into existence?
Mazagon Dock Ltd was setup in 1774 basically to service and repair the East India Company’s ships, so we are almost 250-year-old company, the oldest shipbuilding yard in the country. We were incorporated in 1934 and taken over by the Government of India in 1960.Modern shipbuilding for the Naval War ships started actually through MDL in the country after the navy decided to have its own design department in 1955 to secure the 7,500 km of sea frontiers.
There are three defence public sector undertaking (DPSU) shipyards. Where do you stand?
Besides, MDL, we have Garden Reach Shipbuilders and Engineers (GRSE) and Hindustan Shipyard, that was taken under the wings of the Defence Ministry almost 10 years back. In Cochin, Shipping Ministry have their own shipyard, which traditionally builds merchant ships. MDL has since 1960 built practically the entire range of warships other than landing platform dock (LPD) and landing ship tank (LST) which were smaller versions and given to GRSE.
What’s your USP among the three DPSUs?
GRSE is focused by virtue of its infrastructure available on its LST, LPDs and corvettes. We have built an entire range of platforms which one can think of from naval vessels to offshore platforms at Bombay High for ONGC. Our USP today is building state-of-the-art destroyers and conventional submarines. Destroyers are most highly concentrated level of equipment for both propulsion systems and for the weapons systems.
How many warships have you delivered to the Indian Navy so far?
We have delivered 795 platforms since 1960 and a large number of them have been exported. We have built passenger ships to cargo ships. The last ships which were exported were the multi-support vessels to Bahamas and Mexico in 2014. There are 26 front line warships that have been delivered to the Indian Navy.
When was the last submarine delivered to the Indian Navy?
We are the only ship building yard in the country to have built conventional submarines. The last SSK submarine was delivered in 1994 and currently, we are building six Scorpene class submarines. The first of the Scorpene class submarines has been delivered to the Indian Navy last year.
This month, we will be delivering the second submarine Khanderi and the third submarine, next year by September-October. So, every year, one submarine is going to be delivered to the Indian Navy with the last one being delivered in 2022.
Any of the submarines made by Mazagon Dock have ever been used in wars?
No, our last war was in 1971 and unfortunately we missed that operation. At the time of Kargil, I was also on a ship and we were all deployed at appropriate places in the readiness that in case something happens we would be ready. The issue is we have not seen any war after the 1971. We were not building indigenous platforms at that time. The first major platform that we started building was Leander Class which we delivered in 1972 after the 1971 war to Indian Navy.
During 1971 Ghazi Attack, which submarine was used if it was not an indigenous built ship?
During the Ghazi Attack in 1971 we had some submarines. In 1968, we had this Foxtrot class Russian submarines. Our Kalvari class submarines was decommissioned 1968, but the name still carries on today. So during that time we didn’t had indigenous warships.
How many submarines used by Indian navy are indigenous and what would be the ratio by 2022?
We have three indigenous submarines out of the total 13 and the rest of them are imported. There are eight Russian EKM submarines and four SSK submarines and one Kalvari. By 2022, we will have 18 submarines, of which eight will be indigenous.
The order for six submarines was awarded in 2005 and yet, you delivered just one so far. Why the huge delay?
This contract came in 2005 and we were supposed to deliver the first submarine in 2012. But, there were certain issues in this contract related to the materials. The cost went up and additional sanctions had to be taken.
The contact said that the material procurement was the responsibility of MDL. The material was to be supplied by our collaborator and there were a number of equipments which were to be procured by MDL from a number of small suppliers from whole of Europe and these small time suppliers were not willing to participate, leading to huge delays. They were all nominated by all our collaborator. We decided to bundle up all and ask our collaborator to supply all this.
Even after the orders were placed, there were delays in supply. So, this material issue was the prime problem causing the delay.
The six submarines were awarded to you on nomination basis or bids were called?
It was a nomination. Because as I said we are the only shipyard, which has built submarines in the past and there is a consensus that we want to become self-reliant in submarine construction by 2030 so it is part of that on which MDL got this order.
What’s the cost escalation due to delay?
The cost, which was originally envisaged was ₹16,000 crore, went up to ₹19,000 crore and we had to take additional sanctions and the delays happened because of the procurement of material which has caused the total impact on the delivery of these submarines. So, each submarine is costing between ₹3,000-₹3,500 crore.
The government is planning to award another six submarines. Will you participate in the bids?
Yes, we are waiting for that now. The follow on the P75 India is awaited now so we are all hoping for the RFP that should be coming in. Let’s see, we are eagerly waiting for this order.
The last order you got was on nomination basis. How competitive you will be this time given there will be competition from private payers as well?
We don’t want to take names but we have been in this industry for more than 60 years so a new company cannot start from scratch and be better than us. There are private shipbuilders as well no doubt in that, our work speaks for our self. We need to see that this shipyards can do that overnight and can reach where we reach in less than the years we took.
How the competitive bids are going to help you compared to bagging projects on a nomination basis?
All the government policies today are totally focused towards Make in India. The existing project was the first project in 2005, such mandates probably did not exist that are existing now. You know about the offset clause, we didn’t had the offset clause at that time and consequently there was no benefit. But next time I am very sure that the government will ensure that we get much more out of the next series of submarines and not like how it was
What is your order book?
Our order book at the moment will be roughly ₹53,000 crore to be executed by 2025.
Does this mean a delay of two years now? Earlier I think we were supposed to get all these submarines by 2020. Now he is saying 2022

India to Build Advanced Repair Facility for Scorpene-Class Submarines
Six Scorpene-class submarines are being manufactured at India's Mazgaon Dock Limited facility with the technical support of French naval shipbuilding firm Naval Group, previously known as DCNS. All six submarines are expected to join the Indian Navy by 2022.
With six Scorpene-class submarines expected to join the Indian Navy in the next four years, the country's defence ministry has pushed forward plans to build an advanced repair facility.
The ministry has signed a contract worth $57.59 million with French firm Thales to set up a repair facility at a port off the eastern coast, an Indian Defence Ministry official told Sputnik on the condition of anonymity.

"The ministry signed a contract for setting up an advanced level repair facility for the underwater surveillance system, electronic support measures and external communication system for Scorpene (P-75) submarine for Indian Navy with Thales DMS France," the official said.
The Scorpene-class submarines are being manufactured at the Mazgaon Dock Limited facility with technical support from French naval shipbuilding firm Naval Group, earlier known as DCNS. The first boat was scheduled to enter service in 2012, seven years after signing the deal, but India's MDL shipbuilder could deliver the submarine only as early as December 2017.

The two other Scorpene-class submarines are now set to join the Indian Navy in 2019. Subsequently, every year after 2019, one submarine is going to be delivered to the Indian Navy, with the last one entering service in 2022.
By 2022, the Indian Navy expects at least 18 submarines to be in its service, of which eight will be indigenous.

Second Scorpene submarine ready for induction
Khanderi was launched in January 2017 and has since been undergoing a series of trials
The Navy is set to induct the second Scorpene submarine Khanderi by early May, a defence source said. The remaining submarines in the series are in advanced stages of manufacturing and trials.
“Khanderi has completed all trials and is in the final stages of acceptance. It is expected to be commissioned into the Navy by end April or early May,” the defence source said. Khanderi was launched into water in January 2017 and has since been undergoing a series of trials.
Ready for trials
Another source stated that the fourth submarine Vela is ready to be launched into water for trials around the same time depending on the ocean tide.
Mazagon Dock Limited (MDL), Mumbai, is manufacturing six Scorpene submarines under technology transfer from Naval Group of France under a 2005 contract worth $3.75 bn. After a series of delays in the project, the first submarine of the class Kalvari joined service in December 2017. The entire project is expected to be completed by 2020.
The third in the Scorpene series Karanj which was launched in January last year is in advanced stage of trials and could be ready for induction by year end.
The last two submarines Vagir and Vagsheer are in advanced stages of manufacturing on the assembly line. The fifth submarine is in the final stages of being booted together. The ‘Boot Together’ is where the five separate sections are welded together to form the submarine.
Kalvari is the first modern conventional submarine inducted by the Navy in almost two decades.
In addition, the Navy currently operates four German HDW class submarines and nine Russian Kilo class submarines.
The Navy had last inducted a conventional diesel-electric submarine, INS Sindhushastra, procured from Russia in July 2000.

We must produce atleast 3 more because Project 75(I) is struck in bureaucratic delay for indefinite time period. Subsequent making will be easy, fast and and cheap. What is the status of AIP?
We have advanced into ELF now.

I think....Scorpenes from Malaysian Navy could also make use of this facility.
