After recent commissioning of INS Khanderi (S22) in September 2019 and the launch of the INS Vela (S24) in May 2019, the INS Vagir (S25), the fifth of the series of six Kalvari-class submarines ordered by India in 2005, to be launched.

This event highlights the success of the indigenous submarines construction program of the Government of India. These submarines have been completely built by Mazagon Dock Shipbuilders Limited (MDL) through a transfer of technology from Naval Group, in line with Indian Government’s «Make in India» policy. This series of six submarines are fitted with a number of equipment, built in India by qualified and highly trained industrial Micro, Small and Medium enterprises (MSMEs) which form the sound base of the Indian submarine building ecosystem.

«Naval Group is proud to be part of first of its kind P75 Kalvari program to deliver entirely «Made in India» submarines to the Indian Navy. The P75 program is a major element of the strategic Indo-French partnership developed over the last decades. This launch, amidst Covid-19 challenges, represents a new milestone for this unique industrial program and illustrates the Aatmanirbharta (self-reliance) of Indian Navy and industry», mentioned Alain Guillou, Senior EVP – International Development at Naval Group.

The Scorpene is a conventional-propulsion submarine designed and developed by Naval Group for all types of mission, such as surface warfare, anti-submarine warfare, long-range strikes, special operations or intelligence gathering. Extremely stealthy and fast, its level of operating automation allows for a limited crew which reduces its operating costs significantly. Its combat edge is highlighted by the fact that it has 6 weapon launching tubes and 18 weapons (torpedoes, missiles, mines).

With 14 submarines sold internationally by Naval Group, the Scorpene is an essential reference product in the area of conventional attack submarines (SSK) for Navies across the world. The Scorpene can be adapted to meet special needs of international navies.

Naval Group is present in India through its 100% subsidiary Naval Group India. Established in September 2008, Naval Group India’s mission has been to support the indigenisation of equipment for Scorpene submarine, to develop the Indian defence eco-system, as well as to develop design services in India with talented Indian engineers.

Naval Group India endeavours to be a visionary and to further its involvement in empowering more industries by creating a robust eco-system that can cater to the varied defence needs of the country.

Built in India

Mazagon Dock Shipbuilders Limited (MDL) called «Ship Builder to the Nation», is one of India’s leading Defence public sector undertaking shipyards under the Ministry of Defence continuing their service to the nation with «Make in India» programme. They delivered the second Scorpene submarine «KHANDERI» to the Indian Navy at an event held in Mumbai on 19 September 2019. The Acceptance Document was signed by Cmde Rakesh Anand, Chairman & Managing Director, MDL and RAdm B Sivakumar, Chief of Staff Officer (Tech), Western Naval Command in the presence of MDL Directors and Navy personnel at MDL. The submarine would soon be commissioned into the Indian Navy. It is a milestone event for MDL.

Mazagon Dock Shipbuilders Limited delivers second Scorpene submarine «KHANDERI» to Indian Navy

The submarine «KHANDERI» is named after the wide snouted Saw fish, a deadly sea predator of the great Indian Ocean. The first Submarine Khanderi was commissioned into the Indian Navy on 6th December 1968 and decommissioned on 18th October 1989 after more than 20 years of yeoman service to the nation. In true nautical tradition, she will now be «reincarnated» by MDL to guard the vast maritime area of our nation.

Building of the Scorpene was indeed a challenge for MDL, as the complexity of the simplest of tasks increased exponentially due to all work having to be done in the most congested of spaces. This complexity was further aggravated by the stringent tolerances required to be achieved. However, all of these challenges were accepted head-on and successfully overcome by MDL, without any compromise in quality whatsoever.

The technology utilised in the Scorpene has ensured superior features of the submarine.

The Scorpene class of submarines can undertake multifarious tasks typically undertaken by any modern submarine which include anti-surface as well as anti­submarine warfare.

With the delivery of INS Khanderi (S22), India further cements its position as a submarine building nation and MDL has lived up to its reputation as one of the India’s leading shipyards with a capacity to meet requirements of the Indian Navy by the «Indian commercial and warship building and ship repairing industry report» released in Mumbai during March, 2018 by CRISIL.

The constructions of third Scorpene at MDL, INS Karanj (S23), was started on 31st January 2018, and is currently undergoing the rigorous phase of sea trials. The fourth Scorpene, INS Vela (S24) was recently launched in May 2019, and is being prepared for sea trials, whilst the remaining two submarines, INS Vagir (S25) and INS Vagsheer (S26), are in various stages of outfitting. The Scorpene project would not have been achieved up to the current progress without the unconditional support and active encouragement of the Department of Defence Production (MoD).

It is also pertinent to mention that the two SSK submarines built by MDL in 1992 and 1994 are still serving Indian Navy, after more than 25 years. This is testimony to our skill and capability of MDL. Mazagon Dock Shipbuilders Limited also achieved expertise in submarine refits by successfully executing the medium refit-cum-upgradation of all the four SSK class submarines of the Indian Navy. It is presently carrying out the medium refit and Life Certification of INS Shishumar, the first SSK submarine.

MDL has always been in the forefront of the nation’s progressive indigenous warship building programme. In fact, with the construction of the Leander and Godavari class frigates, Khukri class Corvettes, Missile Boats, Delhi and Kolkata class Destroyers, Shivalik class Stealth Frigates, the SSK submarines and the first Scorpene submarine under its belt, the history of modern-day MDL almost maps the history of indigenous warship building in India.

MDL’s contribution to national security and nation building continues with the P-15B Visakhapatnam class Destroyers and the P-17A class Stealth Frigates.

Recognising the challenges of the future well in time, MDL has completed an extensive modernisation programme, at the end of which, today it is building eight Warships, six Submarines, in its yard, which have four drydocks, three slipways, two Wet Basins and more than sixty thousand square metres of work shop area.

Leveraging the experience, the transfer-of-technology of the Scorpene project, and with its enhanced and upgraded infrastructure, MDL is ready for undertaking construction of future submarines projects.

This is the fourth submarine in the series of the six submarines being built at Mazagon Dock Ltd (MDL), Mumbai under Project 75. The Scorpene-class submarine in the Indian Navy has been termed as the Kalvari-class.

The submarine after completing its out fittings at the dock based on the ocean tide was launched for extensive trials.

At the MDL, the balance two submarines INS Vagir (S41) and INS Vagsheer (S43) are in the advance stages of construction on the assembly line. The Ministry of Defence (MoD) has also approved the acquisition of more than 100 heavyweight torpedoes to be equipped on six Scorpene-class submarines.

 

What is INS Vela (S40) submarine?

INS Vela (S40) is the fourth in the series of the six Scorpene class submarines being constructed at the Mazagon Dock Ltd (MDL) in Mumbai. The out fittings on the submarine have been completed at MDL as per the contract inked between DCNS (now known as Naval Group) of France and MDL as part of Project 75.

Project 75 is already witnessing delays. Out of the six submarines under Project 75, INS Kalvari (S23) has been commissioned in Indian Navy last December. Both INS Khanderi (S22) and INS Karanj (S21) is likely to be commissioned in the Indian Navy. INS Vagir (S41) and INS Vagsheer (S43) are already in the «advanced stages of manufacturing».

As per the contract French Company DCNS (now Naval Group) and the MDL had inked in 2005, the $3.75 billion agreement for the licensed production of six submarines under Project-75 for the Indian Navy and the French Company had decided to transfer technology and jointly build in India. The contract is expected to be completed by next year.

Two other submarines INS Khanderi (S22) and INS Karanj (S21) built at MDL are in line to be commissioned in the Indian Navy. According to senior naval officers INS Khanderi (S22) has completed all trials and is in the final stages of acceptance. According to the 30-year submarine building plan approved in 1999, the Indian Navy needs at least 24 submarines to meet the growing presence of the Chinese presence in the waters.

The Scorpene class submarines which have the capability to be operational in any theatre also have the capability of undertaking different types of missions, which include anti-surface warfare, anti-submarine warfare, intelligence gathering, mine laying and area surveillance. They have top end stealth features which includes advanced acoustic silencing techniques, low radiated noise levels, hydro-dynamically optimised shape and the ability to launch a crippling attack on the enemy using precision-guided weapons.

The Indian Navy is currently operating 4 German HDW-class and 9 Russian Kilo-class submarines. In 2000 July, it had inducted a conventional diesel-electric submarine, INS Sindhushastra (S65), procured from Russia.

Khanderi Launched

INS Khanderi (S51), the second of Indian Navy’s Scorpene’ class stealth submarine, was «launched» by the Hon’ble Raksha Rajya Mantri, Doctor Subhash Bhamre paving the way for her sea trials. Admiral Sunil Lanba, Chief of the Naval Staff and a host of other dignitaries witnessed the launch at Mazagon Dock Shipyard Limited on 12 January, 2017.

The submarine is expected to be delivered to Navy by the year end. She has been christened after her illustrious predecessor, an erstwhile «Foxtrot» class submarine decommissioned in 1989, which is as per the traditions of Indian Navy. The construction of six Scorpene submarines is presently being progressed at Mazagon Dock Shipyard Limited (MDL), under Project 75 with Transfer of Technology from M/s DCNS, France as the Collaborator. The first of the class submarine, INS Kalvari (S50) is presently undergoing sea trials and likely to be commissioned into Navy by Mid-2017. These submarines, post induction, would form the core of Navy’s conventional Submarine Arm.

Speaking on the occasion Doctor Subhash Bhamre said that Project 75 Kalvari is a key milestone in self-reliance and indigenization for the country. Admiral Sunil Lanba, Chief of the Naval Staff said during his address that the fact that Submarine INS Khanderi (S51) compares with the best in the world, speaks highly of the experience and expertise our shipbuilders have gained over the years. He added that as Indian Navy celebrates Golden Jubilee of the submarine arm in 2017, the induction of Project 75 submarines would mark the beginning of a new chapter in our submarine capabilities.

The launching of Khanderi also marks a critical milestone event for the Shipyard which earlier has delivered two Shishumar class submarines in the 90’s and has now strengthened its position as a submarine building yard for Indian Navy. Started as a small dry dock facility for East India Company, MDL today has established itself as a forefront Defence Public Sector Undertaking, with indigenous construction of several ships and submarines for Navy such as P 15 B Destroyers and P 17 A class stealth Frigates being the latest.
