INS Khanderi (S22) is a diesel-electric submarine of the Indian Navy's Kalvari-class, built under Project 75. Commissioned in 2019, Khanderi is part of a modernization effort anchored by Mazagon Dock Limited, DCNS/Naval Group, and indigenous shipbuilding programs. The submarine serves in the Western Naval Command and contributes to Indian maritime deterrence, anti-surface warfare, and anti-submarine warfare capabilities.

Design and Specifications

INS Khanderi is based on the Scorpène-class submarine design developed by DCNS/Naval Group and integrates systems from MBDA, Thales Group, Safran, Rafael Advanced Defense Systems, and Kongsberg Gruppen. The platform employs diesel-electric propulsion with MTU diesel generators, Jeumont-Schneider electric motors, and lead-acid battery storage similar to earlier Scorpène derivatives. Displacement and hull form reflect Type 209 and U-boat design influences adapted for Indian Ocean operations. Sensors include a suite of sonar arrays from Thales, optronics from Safran Optronics, and combat management provided by Armaris/Naval Group systems integrated with indigenous displays from Bharat Electronics Limited. Armament comprises six 533 mm torpedo tubes capable of launching Black Shark heavyweight torpedoes, Exocet/SM39-type anti-ship missiles procured from MBDA/DCNS, and mine-laying capability similar to other conventional submarine classes. Crew accommodations mirror modern standards influenced by Kockums and HDW ergonomics, with air purification, refrigeration, and limited habitability upgrades over older Indian submarines such as INS Shishumar (S44) and INS Sindhuvir (S58).

Construction and Commissioning

Khanderi was constructed at Mazagon Dock Limited in Mumbai under a collaboration between Mazagon Dock Limited and Naval Group following a 2005 contract. The keel was laid amid technology transfer agreements that involved engineers from Mazagon Dock, Naval Group, Hindustan Shipyard Limited observers, and consultants from Bharat Dynamics Limited for weapon integration. Her launch ceremony featured dignitaries from the Ministry of Defence (India), officers from Indian Navy commands, and representatives of subcontractors including Bharat Electronics Limited, Larsen & Toubro, and Tata Advanced Systems. Sea trials tested propulsion, diving depth, crash maneuvers, and weapon firings monitored by Chief of Naval Staff delegates before formal commissioning into the Western Naval Command fleet.

Operational History

Since commissioning, Khanderi has participated in brigade-level and multilateral exercises including Exercise Varuna with the French Navy, Indra Navawar-type engagements with the Russian Navy, and routine patrols across the Arabian Sea and Indian Ocean Region. Khanderi has been deployed for intelligence, surveillance, and reconnaissance missions in coordination with INS Vikramaditya carrier strike elements and P8I Neptune maritime patrol aircraft of the Indian Air Force/Indian Navy maritime aviation wing. Her deployments support Maritime Domain Awareness initiatives linked to Information Fusion Centre efforts and to cooperative operations with navies such as the United States Navy, Royal Navy, Royal Australian Navy, and Japanese Maritime Self-Defense Force under bilateral and multilateral frameworks.

Upgrades and Modernization

Planned mid-life upgrades for the Kalvari-class include integration of Air-Independent Propulsion modules similar to MESMA or Stirling engine concepts trialed by other navies, improved battery systems inspired by advances from Tesla, Inc.-adjacent research and developments in lithium-ion marine applications, and combat system updates from Bharat Electronics Limited and DRDO laboratories like DRDO Naval Systems. Weapon system modernization contemplates integration of indigenous Varunastra torpedoes developed by Naval Science and Technological Laboratory and enhanced shore-based interoperability via C4I links with Indian Strategic Forces Command and naval task force command centers. Sensor suites may be upgraded with next-generation arrays from Thales and Saab AB for better littoral and deep-water detection.

Crew and Life Onboard

The complement of approximately 45 officers and sailors follows training pipelines at Naval Academy (India), Marmagao Naval Dockyard training centers, and submarine schools such as the Submarine Arm School and INS Satavahana. Crew rotations align with doctrines influenced by Royal Navy and French Navy submarine practices; watch systems, emergency drills, and escape training use equipment from SEMCOR-type suppliers and rescue coordination with Indian Coast Guard units. Life aboard features constrained habitable spaces, galley operations supported by contractors like Tatamotors-supplied refrigeration systems, and mental health provisions patterned after programs from Royal Australian Navy and United States Navy submarine crews.

Incidents and Notable Deployments

Khanderi's operational record includes participation in high-profile multinational exercises and classified deterrent patrols; she has been involved in coordinated anti-submarine exercises with INS Kolkata (D63), INS Sahyadri (F49), and P8I Neptune squadrons. While no major maritime accidents have been publicly attributed to Khanderi, Indian submarine operations historically reference incidents involving earlier classes such as INS Sindhurakshak (S63), informing enhanced safety and emergency response measures adopted fleetwide. Notable deployments include interoperability missions with the French Navy during La Pérouse-type engagements and task group integrations supporting Operation Sankalp-style evacuation contingencies coordinated with Ministry of External Affairs (India) assets.
