Boeing P8-A Poseidon in Wikipedia

The Boeing P-8 Poseidon (formerly Multimission
Maritime Aircraft) is an American maritime patrol aircraft developed and produced by Boeing Defense, Space & Security, modified from the 737-800ERX. It was developed for the United States Navy .

The P-8 is a militarized version of the 737-800ERX, a 737-800 with 737-900-based wings. The fuselage is similar to, but longer than, the 737-700-based C-40 Clipper transport aircraft in service with the USN. The P-8 has a strengthened fuselage for low-altitude operations and raked wingtips similar to those fitted to the Boeing 767-400ER, instead of the blended winglets available on 737NG variants.

In order to power additional onboard electronics, the P-8 has a 180kVA electric generator on each engine, replacing the 90kVA generator of civilian 737s; this required the redesigning of the nacelles and their wing mountings.The P-8 has a smoother flight experience, subjecting crews to less turbulence and fumes than the preceding P-3, allowing them to concentrate better on missions.

The P-8 features the Raytheon APY-10 multi-mission surface search radar;the P-8I features an international version of the APY-10. Unlike the preceding P-3, the P-8 lacks a magnetic anomaly detector (MAD) due to its higher operational altitude; its acoustic sensor system is reportedly more effective at acoustic tracking and thus lacking a MAD will not impede its detection capabilities;India's P-8I is equipped with a MAD per the contract request.

Various sensor data are combined via data fusion software to track targets. Following the cancellation of Lockheed Martin's Aerial Common Sensor project, Boeing proposed a signals intelligence variant of the P-8 for the USN's requirement. During the P-8A Increment 2 upgrade in 2016, the APS-149 Littoral Surveillance Radar System (LSRS) will be replaced by the Advanced Airborne Sensor radar.

Crew at work stations inside a P-8
The five operator stations (two naval flight officers plus three enlisted Aviation Warfare Operators/naval aircrewman) are mounted in a sideways row, along the port side of the cabin. None of the crew stations have windows; a single observer window is located on each side of the forward cabin.A short bomb bay for torpedoes and other stores opens behind the wing. The P-8 is to be equipped with the High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC) Air Launch Accessory (ALA), turning a Mark 54 torpedo into a glide bomb for deploying from up to 30,000 ft (9,100 m).

In U.S. service, the P-8A is complemented by the MQ-4C Triton unmanned aerial vehicle (UAV) which provides continuous surveillance. In January 2015, BAE Systems was awarded a contract for the USN's High Altitude ASW (HAASW) Unmanned Targeting Air System (UTAS) program to develop a sub-hunting UAV equipped with a MAD for launching from the P-8.

The P-8 cannot use the hose-and-drogue in-flight refueling method, instead featuring a flying boom receptacle on the upper-forward fuselage, making it, like the USN's E-6 Mercury TACAMO aircraft, reliant on USAF KC-135 Stratotanker, KC-10 Extender and KC-46 Pegasus aircraft for in-flight refueling. In April 2017, the USAF 459th Air Refueling Wing worked with the Naval Air Systems Command to certify operationally the P-8 for in-flight refueling. For extended endurance, six additional fuel tanks from Marshall Aerospace are housed in the forward and rear cargo compartments.
