A militarized version of the Boeing 737 commercial aircraft, the P-8A Poseidon is intended to replace the U.S. Navy’s ageing P-3 Orion fleet as the service’s front-line anti-submarine warfare aircraft. The P-8A has an active multi-static and passive acoustic sensor system, inverse synthetic aperture radar, new electronic support measures system, new electro-optical/infrared sensor and a digital magnetic anomaly detector.
