N37201

This airframe, registered as N37201, is a 1991-built Cessna 550 Citation II with serial number 550-0655. The airframe is owned by U S DEPARTMENT OF HOMELAND SECURITY, a government operator based in Washington, DC, and is registered in the US. The aircraft is identified as an operator-modified surveillance platform in public notes on similar Customs and Border Protection (CBP) Citation II installations and carries a valuation of $900,000 reflecting its age and mission-specific equipment.

The cabin of this specific airframe is configured for an eight-seat layout consistent with medium‑sized Citation II interiors, adapted to support government surveillance and transport missions. Public records note an operator-modified surveillance fit for comparable CBP Citations (documented with Westinghouse APG-66 surveillance radar installations), while flight-deck avionics for this exact airframe are not specified in public records. Typical operations for this registered government asset would include short- to medium-range patrol, transport, and surveillance sorties from its Washington, DC operator base, capitalizing on the aircraft’s near 2,000 nm range and high‑speed cruise. Maintenance considerations for this airframe reflect both normal aging of a 1991 airframe and additional checks associated with missionized equipment and any radar or sensor installations.

The Cessna 550 Citation II occupies the light twin‑engine business jet niche, offering transcontinental capability for its class with a cruise near 369 kts and a service ceiling of 43,000 ft. Competing models historically include other light business jets with similar ranges and capacities; government mission conversions can depress civilian resale value, which is consistent with the airframe’s $900,000 valuation. Buyers and operators should consider the logistics and cost of support for Pratt & Whitney JT15D‑series engines, mission systems removals or integrations, and the impact of a government surveillance history on maintenance records and market desirability.
