The Boeing P-8 Poseidon is an American maritime patrol and reconnaissance aircraft developed and produced by Boeing Defense, Space & Security, and derived from the civilian Boeing 737-800. It was developed for the United States Navy (USN).

The P-8 operates in the anti-submarine warfare (ASW), anti-surface warfare (ASUW), and intelligence, surveillance and reconnaissance (ISR) roles. It is armed with torpedoes, Harpoon anti-ship missiles, and other weapons and can drop and monitor sonobuoys.

The P-8 is operated by the United States Navy, the Indian Navy, the Royal Australian Air Force, and the United Kingdom's Royal Air Force. It has also been ordered by the Royal Norwegian Air Force, the Royal New Zealand Air Force, the Republic of Korea Navy, and the German 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 180 kVA electric generator on each engine, replacing the 90 kVA 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. 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.

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. Other than one large window on each side of the forward cabin for two observers, none of the other crew stations have windows. 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).

Republic of Korea (RoK Navy):
In 2013, the Defense Acquisition Program Administration (DAPA) commenced a KRW 1 trillion (or US$929 million in 2017) procurement program to acquire up to 20 ASW aircraft to replace the Republic of Korea Navy's fleet of 16 P-3Cs; possible candidates included the C-295 MPA, P-8, Saab Swordfish and the SC-130J Sea Hercules. DAPA considered procuring 12 to 20 ex-USN Lockheed S-3 Vikings. In 2017, the ROKN canceled plans to buy refurbished S-3s.

On 26 June 2018, it was announced that DAPA had selected the P-8 and would acquire six aircraft through the US Foreign Military Sales program. On 13 September 2018, the US state department stated it supported the sale of 6 P-8s and notified Congress. South Korea ordered six P-8As in March 2019 with aircraft delivered in 2024.
