Twenty-one unnamed islands that now carry the names of Param Vir Chakra awardees

Background

As the islands return to the news over the Great Nicobar project, their recent map changes are worth recalling.
Twenty-one of the largest unnamed islands of the Andaman and Nicobar Islands were named after twenty-one Param Vir Chakra awardees.
The largest of them was named after the first Param Vir Chakra awardee, Major Somnath Sharma, with each subsequent island named in order of size.
The ceremony was held on Parakram Diwas, the birth anniversary of Netaji Subhas Chandra Bose.
A model of a National Memorial dedicated to Netaji, to be built on Netaji Subhas Chandra Bose Dweep, was unveiled at the same event.
Ross Island had earlier been renamed Netaji Subhash Chandra Bose Dweep, Neil Island became Shaheed Dweep and Havelock Island became Swaraj Dweep.
