Why in news?

Naval Air Station (NAS) Shibpur will be commissioned as INS Kohassa. The move is being undertaken to enhance the operational capability of Andaman and Nicobar Command (ANC).

  • INS Kohassa has been named after a White-Bellied Sea Eagle, which is a large bird of prey endemic to Andaman and Nicobar Islands.
  • By commissioning NAS Shibpur as INS Kohassa, the ANC’s ability to operate independently from all the regions of Andaman and Nicobar Islands will get a great boost.

  • INS Kohassa will become the third Naval Air Base in the Andaman and Nicobar islands after INS Utkrosh at Port Blair and INS Baaz at Campbell Bay.

As part of the Phase II expansion plan, the runway length would subsequently be extended to 3000 metre. This would enable the operation of wide-bodied civil and defence aircraft in the future.

  • The length of the runway was extended to 12,000 ft, enabling both day and night operations.
