INS Kalvari Sea Trials Begins

The first of the Scorpene class submarines ‘Kalvari’ was set afloat by Mazgaon Dock (MDL) in Mumbai for extensive sea trials before being commissioned into the Navy late next year.

On April 6, INS Kalvari was floated out in the presence of Defence Minister Manohar Parrikar. With today’s event, the sea trials of INS Kalvari will commence and are likely to continue for the next 10 months until the commissioning of the submarine. The vessel is scheduled to be commissioned in September 2016.

current affairsThe 66-metre-long INS Kalvari is part of a $3.6 billion contract signed by the defence ministry with French firm DCNS in October 2005 to deliver six vessels.

The contract envisages construction of six SSKs under India’s Project 75 submarine construction programme at MDL under license from DCNS.

While the first four are conventional submarines, the last two are to be equipped with the Air Independent Propulsion (AIP) system, which will enable the vessel to stay underwater for longer.

The Defence Ministry has already stated that after INS Kalvari, the remaining five boats of the Project 75 would be delivered to the Navy by 2020 and “would form the core of the Navy’s submarine arm for the next two decades”.

According to IHS Jane’s Fighting Ships, INS Kalvari is armed with six 533 mm torpedo tubes that can deploy the SM-39 Exocet Block 2 anti-ship missile.

Against its requirement of 24-30 submarines, India currently has only 14 submarines: nine Kilo class (EKMs), four German-designed HDWs (SSKs) and one Akula class nuclear-powered submarine (SSN) on lease from Russia (since 2012).

In comparison, China has 68 submarines and Pakistan, five; Pakistan is also in the process of acquiring another six submarines from China.
