N877SB

The airframe bearing tail number N877SB is a 2017-built Gulfstream Aerospace GV‑SP (G550), serial number 5555, operated on the U.S. registry. The airframe is owned by SB COMPANIES LLC, an LLC based in San Antonio, TX, US; ownership is recorded to that single-member LLC on the U.S. civil register. The aircraft’s registration and manufacturer fit indicate a factory-standard Gulfstream specification and a large-cabin executive configuration reflected in its registry entry. Maintenance status and current market valuation are not published in the supplied data.

The specific cabin of N877SB is listed as a large‑cabin executive layout, with the registry documenting 20 seats; typical VIP outfitting for this model more commonly fits 14–18 passengers, so this airframe’s configuration is on the higher-seating end of Gulfstream VIP variants. Avionics are the factory/typical Gulfstream PlaneView suite, supporting modern navigation, communication and flight management capabilities for long-range business missions. Based on its range and cruise speed, operations for this aircraft are consistent with transcontinental and intercontinental point-to-point executive transport, corporate shuttle duties, or charter missions originating from its owner’s base in San Antonio. No specific unique amenities or maintenance records were supplied for this serial.

The Gulfstream GV‑SP (G550) family occupies a long-range large-cabin niche, offering extended intercontinental capability, high cruise speed and high operating ceiling compared with smaller business jets. Competing models in the segment include long‑range offerings from Bombardier and Dassault; buyers target this class for transoceanic range, cabin comfort and proven systems common to the Gulfstream line. For resale and maintenance considerations, the G550’s two Rolls‑Royce BR700 engines and high-tech PlaneView avionics command steady demand, though individual airframe value and marketability depend on configuration, maintenance history and total time on the specific serial 5555.
