N811MK

This airframe, registered as N811MK, is a Gulfstream G650ER built in 2021 with serial number 6453. The aircraft is owned by MERCK SHARP & DOHME LLC, a corporation based in West Trenton, NJ, US, and is registered in the US. Registered to MERCK SHARP & DOHME LLC upon delivery, the airframe's FAA records indicate a 22-seat configuration and corporate operation from its East Coast base. Estimated value is $35,600,000, reflecting a relatively recent build and typical corporate condition for a factory-newer large-cabin business jet.

FAA records for this specific G650ER show 22 seats, while typical executive outfitting for the type is configured for 12–16 passengers with forward and aft lavatories and wet galley options; this airframe therefore appears registered to a higher-density seating arrangement while retaining the outfitting flexibility common to the model. Avionics fit includes Gulfstream’s PlaneView II with options for Enhanced Vision System (EVS) and Head-Up Display (HUD), supporting long-range, high-altitude corporate missions. Typical operations for this operator likely include transcontinental and intercontinental executive transport within the aircraft’s 7,500 nm range and high-cruise profile of 488 kts, operating regularly from the owner’s home base in the northeastern United States. Maintenance considerations follow Gulfstream support for BR725-powered airframes and corporate fleet upkeep practices.

The Gulfstream G650ER occupies the long-range, large-cabin niche of the business-jet market, offering extended-range performance that competes with ultra-long-range models from Bombardier and Dassault. With a service ceiling of 51,000 ft and a typical long-range cruise, the platform appeals to corporate flight departments and fractional/charter operators demanding nonstop intercontinental capability. Resale and maintenance considerations for this 2021-built airframe reflect favorable demand for relatively new, factory-era G650ERs, though corporate registration in a 22-seat layout may influence interior refurbishment and market positioning relative to typical 12–16 passenger executive interiors.
