N840DS

This airframe, registered as N840DS, is a Boeing P-8A Poseidon (a 737-800ER derivative) built in 2024 with manufacturer serial number 170478. The aircraft is owned and operated by the United States Navy and carries a US civil/military registration (US) consistent with government-operated fleet assets. Entered service in 2024 as part of the Navy's expanding maritime patrol and anti-submarine warfare inventory, the airframe is configured from delivery with mission systems rather than a civilian passenger interior. Public registry and valuation details beyond ownership and registration are Not published.

The aircraft is fitted with a mission compartment in lieu of a conventional passenger cabin; it features tactical operator stations encompassing both flight crew seating and mission crew consoles, along with sonobuoy and weapon bays rather than civilian cabin seating. Its avionics and mission systems suite centers on a Raytheon AN/APY-10 maritime surveillance radar integrated with signals intelligence, electronic warfare, and mission management systems to enable long-endurance anti-submarine, anti-surface, and ISR missions. Typical employment profiles for this specific airframe include extended maritime patrols from its U.S. Navy bases, deployed sortie durations leveraging the aircraft’s 4,500 nm range and efficient cruise speed, and integrated tasking with fleet and joint assets; maintenance considerations emphasize mission-systems support and weapons-handling infrastructure specific to the P-8A configuration.

As a member of the Boeing P-8A Poseidon family—derived from the Next Generation 737-800ER airframe—this aircraft occupies a performance niche combining commercial airframe commonality with specialized maritime patrol capability. Competing platforms in the broader market niche include various turboprop and converted narrowbody maritime patrol aircraft, but the P-8A is distinguished by higher cruise speed, altitude capability, and integrated mission systems. Demand is driven primarily by government and military buyers rather than civil charter customers; resale and maintenance considerations for this airframe type focus on lifecycle sustainment of mission equipment, spares for the CFM56-7B27 engines, and depot-level support managed through defense supply chains.
