How India lags China in submarine race

New Delhi:  A recent visit by an advanced Chinese Yuan-class submarine to Karachi after traversing the Arabian Sea worried Indian authorities concerned about China's growing undersea-warfare capabilities — more than four times as large as

nuclear submarine 

Nuclear-powered submarines are of two types: attack submarines (SSN) and fleet ballistic missile submarines (SSBN).
Attack submarines are smaller and faster compared to their ballistic-missile counterparts. SSNs are designed to attack enemy ships and submarines using torpedoes and shore facilities with cruise missiles with conventional high-explosive warheads. SSBNs carry ballistic missiles with nuclear warheads.

India's first nuclear submarine was leased in 1988 from the Russian Navy and returned in 1991. The present nuclear submarine, INS Chakra, is considered one of the deadliest non-American attack boats in the world.
India has nine Sindhughosh-class or Kilo-class diesel-electric submarines. They were built under a contract between Russia's Rosvooruzhenie and the Indian defence ministry. The other four are German-made Shishumar-class diesel-electric submarines (Type 1500).
India strives to expand submarine fleet.
India plans to add 15 submarines:  six conventional French-designed vessels, build six nuclear attack boats and three nuclear ballistic-missile submarines.
The plan to build six French-designed Scorpene-class submarines is called Project 75. The first diesel-electric submarine of this class — INS Kalvari — was launched on April 6, 2015 and is expected to be inducted into the navy by 2016. The other five will be delivered by 2020.

missile submarines
The Scorpene is a state-of-the-art conventional submarine which incorporates advanced stealth characteristics that make detection difficult. The submarine features anti-ship missiles and advanced torpedoes.
 India's first indigenously built nuclear-propelled strategic submarine, INS Arihant (destroyer of the enemy), was launched in 2009 and is currently under trial. The SSBN gives India a nuclear triad of missiles that can be launched by air, from land and under the sea.
Another indigenous SSBN, INS Aridhaman, is also under construction, and work on a third will start soon, according to this report.
China already has three Jin-class SSBNs in service, according to this report, and may have eight in service by 2020.
A cheaper, quicker option: grow anti-submarine capabilities
To counter China's growing submarine clout, the defence ministry on July 14, 2015, cleared a proposal to purchase four more US-built P-8I long-range, anti-submarine warfare (ASW) maritime patrol aircraft.
India already has six such aircraft, according to this report.
In May 2015, INS Kavaratti, a fourth indigenously-built ASW corvette, was launched. It has state-of-art weapons and sensors, including a medium-range gun, torpedo tube, rocket launchers and a helicopter.
India is in the process of finalising a contract with the US' Sikorsky Aircraft Corporation for 16 S-70B ASW choppers. The deal has been pending for the last 15 years.
Most Indian ships lack ASW helicopters at a time of China's growing under-sea dominance.
