On 11 May 1985, the air station was formally commissioned as INS Utkrosh by then Defence Minister of India, P. V. Narasimha Rao, making it the first naval air station in the Andaman and Nicobar Islands.[3] Its location makes it an important strategic station for protecting India's maritime interests in the Bay of Bengal. It also serves as an important facility for undertaking humanitarian operations, such as disaster relief and evacuation of medical emergencies from the remote islands.
The facilities at INS Utkrosh have been significantly upgraded. The runway has been lengthened to almost 11,000 feet (3,400 m).[4] Except for the civilian terminal operated by the Airports Authority of India, all other air traffic operations over Port Blair are undertaken by INS Utkrosh.
The geography makes this a difficult airfield for aircraft, as a hillock at one end means that planes can land or take off only in one direction. Winds change here every six months, so pilots have to either take off or land with strong tail winds.[3]
