The Boeing P-8 Poseidon (formerly the Multimission Maritime Aircraft or MMA) is a military aircraft developed for the United States Navy (USN). The aircraft has been developed by Boeing Defense, Space & Security, modified from the 737-800ERX. The P-8 conducts anti-submarine warfare (ASW), anti-surface warfare (ASUW), and shipping interdiction, along with an electronic signals intelligence (ELINT) role. This involves carrying torpedoes, depth charges, SLAM-ER missiles, Harpoon anti-ship missiles, and other weapons. It is able to drop and monitor sonobuoys. It is designed to operate in conjunction with the Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance unmanned aerial vehicle. The aircraft has been ordered by the Indian Navy as the P-8I Neptune, and the Royal Australian Air Force. Development[edit] Origins[edit] The Lockheed P-3 Orion, a turboprop ASW aircraft, has been in service with the United States Navy since 1962.[7] In the 1980s, the Navy began studies for a P-3 replacement, the range and endurance of which was reducing due to increasing weight and airframe fatigue life limitations. The specification required a new aircraft to have reduced operating and support costs. In 1989, the Navy awarded Lockheed a fixed-price contract to develop the P-7, but this was canceled the following year.[8] A second competition for a replacement began in 2000. Lockheed Martin submitted the Orion 21, an updated new-build version of the P-3.[9] Boeing's proposal was based on its 737-800 airliner.[10] BAE Systems offered a new-build version of the Nimrod MRA4, a British jet-powered maritime patrol aircraft. BAE withdrew from the competition in October 2002, recognizing that without a production partner based in the United States, the bid was politically unrealistic.[11] On 14 May 2004, Boeing was selected as the winner.[12] In June 2004, the U.S. Navy awarded a development contract to Boeing.[13] The project was planned to be for at least 108 airframes for the Navy.[14] More orders are possible from the other nations operating over 200 P-3s. Project value is expected to be worth at least $15 billion. Raytheon, Northrop Grumman, Spirit AeroSystems, GE Aviation Systems, Marshall Aerospace and Defence Group, CFMI, BAE Systems, and Marotta are major subcontractors.[15] In July 2004, the Navy placed an order for five MMA aircraft, and the first flight-test aircraft was to be completed in 2009.[14] On 30 March 2005, the P-8A designation was assigned to the aircraft.[16] Design phase and testing[edit] Rollout of the P-8 on 30 July 2009 The P-8 is to replace the P-3 Orion.[17] At first, it will be equipped with legacy P-3 systems, but later upgrades will incorporate more advanced technology. The Government Accountability Office credited the incremental approach with keeping the project on schedule and on budget. In 2008, the Naval Air Systems Command (NAVAIR) deleted the requirement for the P-8A to be equipped with magnetic anomaly detection (MAD) equipment as part of an effort that reduced weight by 3,500 lb (1,600 kg) to improve endurance and range. A hydrocarbon sensor detects fuel vapors from diesel-powered submarines and ships.[18] The P-8's first flight was on 25 April 2009.[1] The second and third P-8s had flown and were in flight testing in early August 2010.[19] On 11 August 2010, the US approved the P-8 for low-rate production.[20][21] A P-8 released sonobuoys for the first time on 15 October 2010, dropping six sonobuoys in three separate low-altitude passes.[22] In 2011, it was found that the P-8's ice detection system was defective due to the use of counterfeit components; allegedly these computer parts were poorly refurbished and sold to subcontractor BAE Systems as new by a Chinese supplier.[23] A P-8A Poseidon flying alongside a Lockheed P-3 Orion, close to Naval Air Station Patuxent River, Maryland, 2010 The first production P-8A was handed over to the Navy on 4 March 2012. It flew to Naval Air Station Jacksonville, Florida, for training with the Fleet Replacement Squadron (FRS), Patrol Squadron 30 (VP-30).[2] On 24 September 2012, Boeing announced a $1.9 billion order for 11 aircraft.[24] On 10 June 2013, a DoD Inspector General (IG) report noted that the Navy should delay full-rate production over a lack of key information to assess if the P-8 meets operational requirements. Additional testing was also needed to guarantee a 25-year lifespan.[25] Boeing executives dismissed the report, saying that the test program is on track.[26] In 2013, full-rate production was delayed until the P-8 could demonstrate it can survive its 25-year lifespan without structural fatigue, overcome mission-limited deficiencies, track surface ships, and perform primary missions.[27] On 24 June 2013, a P-8 successfully scored a direct hit with a live AGM-84D Block IC Harpoon anti-ship missile during weapons integration testing.[28]
