The Indian Navy received its fifth P-8I maritime patrol aircraft from Boeing, the company reported.

The Poseidon, delivered under a 2009 order for eight aircraft, was configured to Indian Navy requirements and features Indian-built sub-systems.

"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," said India Deputy Chief of Naval Staff Vice Adm. RK Pattanaik.

Added Dennis Swandon, vice president of Boeing Defense, Space & Security in India, "This is another important milestone for the program, and we look forward to continuing our great relationship with India.

"We'll deliver one more P-8I before the end of the year, followed by two in 2015."

The P-8 Poseidon is based on the commercial 737-800ERX aircraft and is used for anti-submarine warfare, anti-surface warfare, and electronic signals intelligence. It carries torpedoes, depth charges and missiles, as well as sonobuoys.

The "I" variant for India features an aft radar and a magnetic anomaly detector.

The aircraft has a maximum speed of 564 miles per hour, a combat radius of 1,200 miles and a service ceiling of 41,000 feet.

The "I" variant, as well as the "A" variant for the U.S. Navy, are built using a first-in-industry, in-line production process.
