The aircraft was received by the Air Force at Naval Air Station Rajali in Tamil Nadu, where the Navy has deployed its long-range anti-submarine warfare aircraft, Navy officials said.
"The P-8I program is progressing on schedule, and the aircraft are providing the capabilities to meet our maritime reconnaissance and anti-submarine warfare requirements," Navy's Deputy Chief Vice Admiral RK Pattanaik said at a function to receive the aircraft at Rajali.
The US Navy also operates similar aircraft which are named P-8A Poseidon and India was its first international customer.
The Indian Navy is now planning to procure eight more medium-range surveillance aircraft to plug gaps in its maritime zone.
