N990SP

The airframe with tail number N990SP is a Gulfstream Aerospace GIV‑X (G450) built in 2012, serial 4260, and registered in the US. Current registry records list ownership by GD INVESTMENTS II LLC, an LLC based in Hingham, MA, US, which is the documented operator/home base for this airframe. The type is a fixed‑wing multi‑engine business jet, and the airframe carries a reported market value of $12,300,000; no other public registry actions are published for this specific serial in the supplied data. Acquisition by GD INVESTMENTS II LLC is the principal noted ownership event in the available record.

Registry information for this specific G450 lists 22 seats, though typical G450 executive cabin fits are commonly 12–16 seats arranged in three zones (forward galley, mid cabin seating, aft conference/berth); this airframe’s higher seat count implies a high‑density or hybrid configuration for charter, corporate group transport, or special‑mission use. Avionics are listed as Honeywell PlaneView (Primus Epic / PlaneView), supporting modern cockpit management and common fleet interoperability for Gulfstream operators. Typical missions enabled by the G450 performance values here include transcontinental and intercontinental business travel within the aircraft’s 4,350 nm range and long‑cruise capability at 459 kts, operating to standard business‑jet altitudes up to 45,000 ft. Maintenance considerations for this airframe center on the twin Rolls‑Royce Tay Mk 611‑8C powerplants and aging‑cycle airframe workstreams consistent with a 2012 build and its reported market valuation.

The Gulfstream GIV‑X (marketed as the G450) occupies the large‑cabin, long‑range business jet niche, combining transcontinental range with high‑cruise speed and a multi‑zone cabin philosophy. Competing models occupy similar long‑range, large‑cabin segments and buyers seek a balance of range, cabin flexibility, and lifecycle costs; the presence of Honeywell PlaneView avionics aids resale and charter appeal. Resale and maintenance considerations for this serial reflect its 2012 build year, twin Tay engines with defined overhaul cycles, and a reported value of $12,300,000, factors that influence buyer demand and operator lifecycle planning.
