1980â€™s was Glorious years for Indian Navyâ€™s submarine arm, it had an impressive 21 Submarine under its arms, not only that, it was successfully operating Russian leased nuclear submarine INS Chakra under its command. So went wrong, where did India lose the plot, that now India navy only has 14 submarines under it fleet , and in next few yearâ€™s numbers will only decline? .major reason for that fallout can be blamed on HDW Submarine scam ,which came into light when Rajiv Gandhi was the Prime Minister of India. The case was registered by the defence minister at that time V P Singh in March 1990 after receiving a telegraphic message from the Indian Ambassador in Germany that time about the payment of 7 % to some middlemen. India inducted four Dr Gabler 1500 HDW/IKL designed submarines between 1986 and 1994, first two were delivered by the submarine manufacture HDW. In 1982 had send various Naval officers and MDL workers to Germany for training in the construction of those submarine at a great expense, with successful TOT and with local submarine building expertise at hand, India was able to build only two HDW submarine and plans were to construct at least reported 4 more submarine locally .surfacing of the HDW scam, not only lead to blacklisting of the company but also long and lengthy CBI probe into the matter. This almost bought all Submarine purchase to stand still. How worse was it for Navy? Well last submarine inducted was 11 years ago, and in last 21 years, only two were inducted .last one to be inducted was the Russian built Kilo class submarine INS Sindhushastra (S 65) which was commissioned in June 2000. Sleep could have gone for few more years, but India got a rude shock, when Pakistani purchased new modern French built Agosta 90B submarine in 99, even with this event, India took its own time to select French Scorpion submarine and went into an agreement only in 2005. After HDW scam, local expertise were lost on submarine building and docks were empty and idle for two decades , and now we are painfully re-learning that art , production of Scorpion submarine locally ,without experts at hand has already seen delays , so much so that first submarine will only be inducted in 2015 , instead on this year . Indiaâ€™s Submarine building plan approved by Government of India in 1999, had approved 24 conventional (Diesel) submarine by 2030, it was divided into three phase. First Phase: procurement of Six French Scorpion submarine under Project 75, first submarine to be inducted by 2011, but after delays it has been put to 2015. Second Phase: procurement of six more submarine under Project 75 (I), for which French have proposed a larger and advance Scorpion variant , which has been backed by Mazagon Docks . RFP (request for proposal) has been send to Rosoboronexport (Russian), DCNS/Armaris (French), HDW (German) and Navantia (Spain). Short listing and detailed technical and commercial negotiations will follow, before the actual contract can be inked by 2014-15. Indian navy wants private shipyard to build this phase of the submarines, since it feels that Mazagon Docks are overloaded with construction of Scorpion submarine. It seems Navy might have learned from its mistake and will purchase first two submarines from selected vendor and give enough time to train officials and engineers. Third Phase: Locally developing 12 Diesel Submarine in India, with construction to begin post 2020, but development or even research, seems to be on back burner and nowhere in Horizon. On Nuclear Submarine front , Indiaâ€™s Much publicised Secret Nuclear submarine project under Advanced Technology Vessel (ATV) , was been developed at snail pace , and DRDO took close to 3 decades in its development , but first two decades only involved development and research and construction activity was carried out only in last decade .lead ship of Advanced Technology Vessel (ATV) INS Arihant (S-73) was launched and introduced to the public on 26 July 2009, and currently carrying out sea trials , and the second Submarine under Arihant class is reported to be under construction . The completion of the INS Arihant will make India one of six countries in the world with the ability to design, build, and operate its own nuclear submarines .But India is yet to launch its SSBN class submarines . Indian Navy has now 14 conventional submarines, of which 10 are Russian build Kilo class submarine and 4 German designed HDW Submarine, first 6 kilo class submarine in Indian navy at present are 22 years old and ageing. And the Seventh Kilo Class Submarine (Sindhukirti (S61)) which was under refit in Hindustan Shipyard Ltd (HSL) to enable it to fire Uran missiles with Russian help is in dismal condition and after close to four years in docks, submarine is still not ready and it has been citied that the submarine is has good has lost due to poor engineering works carried out on the hull of the submarine .so Indian navy is unofficially down to 13 Submarines at present. Indian Economy is expanding and it requires strong navy to protect its interest, energy security. Stability in the Indian Ocean will depend on Indian navy; China with close to 60 Conventional submarines is also more interested in securing its energy needs and is more interested in dominating Indian Ocean .dominance which Indian navy has been holding for decades now.
