Boeing [NYSE: BA] on July 16 successfully completed the final design review (FDR) for P-8I, India's long-range maritime reconnaissance and anti-submarine warfare aircraft. The P-8I, based on the Boeing 737 commercial airplane, is a variant of the P-8A Poseidon that Boeing is developing for the U.S. Navy.

Completion of the FDR locks in the design for the aircraft, radar, communications, navigation, mission computing, acoustics and sensors, as well as the ground and test support equipment. It also paves the way for the program to begin assembling the first P-8I aircraft.

"For P-8I, we are incorporating not only India-unique design features, but also India-built subsystems, so this agreement that the design addresses all customer requirements is a huge milestone," said Leland Wight, P-8I program manager for Boeing. "It also leads us to the program's next stage: We are on track to start fabricating the P-8I's empennage section before the end of this year."

During the five-day FDR held in Renton, Wash., Indian Navy officers met with Boeing representatives from Defense, Space & Security and Commercial Airplanes to review relevant design information and performance against specifications.

"The P-8I's unique capabilities are tailored to India's maritime-patrol requirements. It has the reach and capability to defend India's vast coastline and maritime waters," said Vivek Lall, India country lead, Boeing Defense, Space & Security.

Boeing will deliver the first P-8I to India within 48 months of the original contract signing, which took place in January 2009. India is the first customer for the P-8 outside the United States.
