It appears that the Indian Navy does not allocate a certain type of vessel to a particular unit. Rather, different vessel types are assigned to units as they are commissioned and the units often switch to very different vessel types from what they might been equipped with originally. For instance, the 22nd Missile Vessel Squadron currently equipped with Tarantul-I Class corvettes may have been the former 22nd Destroyer Squadron and the 31st Patrol Vessel Squadron currently equipped with Petya-II Class frigates may be the former 31st MCM Squadron. Also note that some squadron numbers are not sequential and often repeat themselves, albeit with different vessel types - such as the 21st Missile Vessel Squadron and 21st MCM Squadron. The list below is incomplete, as it does not include the squadron numbers/locations for the Godavari & Brahmaputra Classes of frigates, the Khukri & Kora Classes of corvettes, the Trinkat & Bangaram Classes of fast patrol vessels and other naval ships.
