P-8A Poseidon

On September 30, 2004, the Boeing MMA proposal passed the critical design review following three days of intensive system requirements review by the US Navy. The critical design review is deemed to be a critical milestone needed to get the US Navy's green light for the system development. The Boeing-led team completed the three-month high-speed wind tunnel testing on March 18, 2005. The testing program logged more than 1,300 hours of simulated flight. In addition, Boeing also released that the US Navy was given P-8A designation to the MMA aircraft. On June 2, 2005, Boeing changed the P-8A original wingtip design from a blended winglet to a commercial backswept wing tip. The entry into service date of the first P-8A aircraft was also delayed one year from 2012 to 2013. In April 2006 Boeing unveiled a new Long-range Maritime Patrol Aircraft based on its P-8A/737 design to meet the requirements of the Indian Navy. India needs call for eight reconnaissance and anti-submarine warfare aircraft by 2010. In early 2010 the program's scope was increased from 113 to 122 aircraft. The P-8A program achieved initial operational capability (IOC) on November 28, 2013. As of December 2013, the program's scope was decreased from 117 to 109 aircraft. As of 2021, the US Navy P-8A fleet is expected to include 128 aircraft.
