INS Kohassa

INS Kohassa was established as Naval Air Station (NAS) Shibpur in 2001 as a Forward Operating Air Base (FOAB) for enhanced surveillance in North Andaman. Presently, Dornier 228 aircraft and HAL Chetak helicopters of the navy and the Indian Coast Guard land at Shibpur once in a week, on their transit for surveillance of North Andaman Islands. In addition, the Indian Air Force operates its Dornier aircraft between Port Blair and Diglipur every Thursday for courier duties. In 2009, the government of India accorded sanction to commission NAS Shibpur as a full-fledged air station.^[8] The length of the runway is being extended to 12,000 ft and will enable day and night operations.^[9]

Dornier 228s of the navy and coast guard conducted search for Malaysia Airlines Flight 370 from this base.^{[citation needed]}

In 2017, it was reported that the runway length would be extended to 3000m after acquisition of about 100 hectares of land. This will enable the operation of wide-bodied civil and defense flights.^{[citation needed]} The station, earlier known as NAS Shibpur, was renamed as INS Kohassa after the extension of facilities in January 2019.^[10][11]
