The submarine is expected to be commissioned with the Indian Navy in the coming weeks. Karanj was launched by MDL on 31 January 2018.
Six Scorpene-class submarines have been ordered by India in 2005 as part of the Project 75 program. They are constructed locally by the Mazagon Dock Limited shipyard in Mumbai, with assistance of Naval Group, designer of these submarines. Two submarines, Kalvari and Khanderi, have already been commissioned into the Indian Navy. The fourth submarine of the class, Vela, are conducting sea trials, whilst construction of the sixth and final submarine, Vagsheer, is ongoing.
About India’s conventional submarine programs
According to official documents, the Indian Navy has two ongoing conventional submarine programs, with a third one on the way.
Phase I – P-75
Six submarines of Scorpene class (P-75) are to be constructed at Mazagon Dock Limited, Mumbai. Two Submarines of the project namely INS Kalvari and Khanderi have been commissioned in December 2017 and September 2019 respectively. The balance submarines are likely to be inducted every nine months. The last submarine is likely to be delivered in June 2022.
Phase I – P-75(I)
Six submarines are to be constructed under P-75(I) under the Strategic Partnership model promulgated by the Defence Acquisition Council (DAC) on 31 May 2017. AoN for the case has been accorded by DAC on 27 February 2019. A multidisciplinary Empowered Project Committee (EPC) has been constituted by MoD on 15 February 2019 to steer the project from ‘EoI issuance’ to ‘Contract Conclusion’. The Request for Expression of Interest (REoI) for shortlisting of SPs and Foreign, Original Equipment Manufacturer (OEMs) was issued on 20 June 2019 and 02 July 2019 respectively. The response of SPs have been received on 11 September 2019. The response of Foreign OEMs have been received on 24 September 2019. The Request for Proposal (RFP) for the case would be issued in mid-2020. The induction of the submarines would be between 2027-2032.
Twelve submarines of an indigenous design are envisaged to be constructed in India in this phase with the experience gained and technology absorbed from construction of submarines under Phase I.
About Scorpène type submarine
Scorpène is the conventional submarine designed by Naval Group for the export market. It demonstrates both Naval Group’s ability to deliver best in class submarines and to conduct successful transfers of technology. Today 14 Scorpène submarines are in operational service or being built, for the Chilean Navy (2 units), the Malaysian Navy (2 units), the Indian Navy (6 units) and the Brazilian Navy (4 units).
The Scorpène design is adapted to fit each navy’s specific requirements. Thus, the Brazilian Scorpène is slightly longer to carry a larger crew, almost double the patrol range, and be able to cover greater distances.
Scorpène is ideally suited for action and operational effectiveness. Robust and enduring, it’s an ocean-going submarine also designed for shallow waters operations. Multipurpose, it fulfils the entire scope of missions such as anti-surface and anti-submarine warfare, special operations, offensive minelaying and intelligence gathering. Integrating improvements from French Barracuda-Class fast-attack submarine, Scorpène has cutting-edge capabilities.
