Marking a significant milestone for the Navy in three decades, India simultaneously deployed 11 conventional submarines for operations.
Conventional Submarines in India
Currently, India operates 16 conventional submarines, including fiveKalvari-class (French Scorpene), four HDWs Shishumar-class (German Type-209) and seven Sindhugosh-class (Russian Kilo) submarines. An additional Scorpene class (Kalvari-class submarine) is still to be commissioned.
Operational Availability:
Scorpene class: The Scorpene submarines are brand new, hence, their availability ratio is much higher.
HDWs (German): The German HDWs are the most reliable and high on performance. These submarines will last another 10-15 years.
Kilo-class (Russian): The Kilos are very good but their availability ratio is down. Also, they have undergone upgrades. Most of them were commissioned in the 1980s and one of them has already been decommissioned.
