What is the current status of the submarine fleet? How many are operational, under refit and under construction?

The navy maintains the required force level of submarines as per the Maritime Capability Perspective Plan, which factors our perceived threats. Our current force mix comprises 14 submarines — nine Sindhughosh class and four Shishumar class and INS Chakra. The six Kalvari Class submarines under Project 75 are under construction. Kalvari, the first one, will be commissioned soon and the rest would be inducted by 2020.

Additionally, six modern submarines under Project 75(I) programme would be inducted for which the RFI was issued in 2017 and the project would be executed under the Strategic Partnership Model of the government of India
