N1999B

This entry covers airframe N1999B, a factory-built Gulfstream G650ER completed in 2023 by Gulfstream Aerospace Corporation with serial number 6546. The airframe carries a United States registration (US) and is listed with a long-range executive configuration; public records for a detailed ownership timeline, operator or home base are not published. No notable registry actions beyond initial certification and registration are published, and appraisal or condition summaries have not been released publicly. The aircraft’s new-build status and contemporary systems suggest it entered service in a current-technology standard condition consistent with year-of-build expectations.

The cabin of N1999B is fitted in an executive long-range layout with forward and/or aft galley options and typical seating for up to 19 passengers, allowing flexible combinations of conference, lounge and private stateroom zones. Avionics are provided by Gulfstream PlaneView II, supporting advanced flight-deck integration, long-range navigation and automated flight systems for extended overwater and intercontinental missions. Typical mission profiles for this airframe include transoceanic executive transport and long-haul business missions enabled by a 7,500 nm range and a high cruise speed of 488 kts, operating at optimum altitudes up to 51,000 ft. Maintenance considerations align with BR725 engine support packages and Gulfstream factory support; specific maintenance records for this serial are not published.

As a member of the Gulfstream G650ER family, N1999B occupies the ultra-long-range, high-speed end of the business-jet market, offering performance optimized for nonstop intercontinental routes. Competing platforms in this niche include other ultra-long-range large-cabin types that balance speed, range and cabin comfort. Buyer and charter demand for late-build G650ERs typically centers on operators prioritizing range and cabin volume; resale considerations for this 2023 airframe will reflect low utilization potential, manufacturer support, and BR725-specific maintenance cycles.
