According to information published by Royal Norwegian Air Force on May 27, 2022, the third out of five P-8 Poseidon maritime patrol aircraft has arrived in Norway.
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 (USN).
The P-8 operates in the anti-submarine warfare (ASW), anti-surface warfare (ASUW), and intelligence, surveillance and reconnaissance (ISR) roles.
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.
It is armed with torpedoes, Harpoon anti-ship missiles, and other weapons, can drop and monitor sonobuoys, and can operate in conjunction with other assets, including the Northrop Grumman MQ-4C Triton maritime surveillance unmanned aerial vehicle (UAV).
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.
