Its just more "outsourcing".
India will now perform the roles formerly done by the RN... New Delhi will soon announce the formation of the "British Isles Squadron" of the Indian Navy... specifically tasked with taking over the maritime security of the UK, and protection of its shipping interests.
If the Royal Marine Amphibious Squadron (the Albions & Bays) need a warship escort for any operations, the BIS of the IN will deliver the appropriate capability.
