The P8-I piloted by its squadron commander made its first landing at the INS Utkrosh airfield yesterday, a Navy release said.
The event was attended by Commander-in-Chief of Andaman and Nicobar Command Air Marshal P K Roy besides senior officers of the unified command.

The aircraft is equipped with both foreign as well as indigenous sensors for maritime reconnaissance, anti-submarine operations and electronic intelligence missions.
