N704SG

This article covers the specific Gulfstream airframe bearing tail number N704SG, a Gulfstream G-IV (G400) built in 2003 with serial number 1504. The aircraft is owned by WILMINGTON TRUST CO TRUSTEE, a corporate trustee based in Wilmington, DE, and is registered in the US. Recorded valuation and condition highlights list the airframe at an estimated market value of $5,800,000, reflecting its age, configuration and typical G-IV maintenance profile.

The cabin of N704SG follows a typical three-zone executive layout, configured for 12–19 passenger seating depending on operator-specific choices, and notes include a forward galley, mid-cabin seating cluster and aft lavatory. Avionics are reported as the typical G-IV/G400 fit, commonly Collins Pro Line or Honeywell-based suites subject to retrofit or upgrades. Operationally this airframe, registered in the US, is suited to transcontinental and transoceanic corporate transport missions within the platform’s 4,220 nm range and cruise speed of 460 kts. Maintenance considerations for this specific aircraft reflect G-IV program commonality, engine support for the Rolls-Royce Tay 611-8 powerplants, and owner-custodian arrangements associated with a corporate trustee.

The Gulfstream G-IV/G400 family occupies a long-range large-cabin business jet niche, offering high cruise speed and transcontinental capability exemplified by N704SG’s 4,220 nm range and 45,000 ft ceiling. Competing models in its era include other large-cabin, long-range business jets; buyer and charter demand for platform examples depends on configuration, avionics retrofit status and hours/maintenance history. Resale and maintenance considerations for this airframe are influenced by its 2003 manufacture date, ownership structure under WILMINGTON TRUST CO TRUSTEE, and the recorded market value of $5,800,000.
