India may be slow to mature new submarine projects compared to China, but it is far faster than Australia.
Australia launched its latest submarine, HMAS Rankin in 2001.
In that time India has leased Chakra II SSN in 2011, launched several Kalvari SSKs since 2015 and commissioned two Arihant-class SSBNs since 2016.
