N455WG

This entry covers the airframe bearing registration and tail number N455WG, a 1992-built Gulfstream G-IVSP with manufacturer serial number 1205. The jet was produced by Gulfstream Aerospace and is recorded as owned by ALLIANCE AVIATION GROUP LLC, a corporate owner based in Wilmington, Delaware, United States. The aircraft is registered in the US and is associated with corporate operator basing and maintenance oversight tied to its owner’s Wilmington, DE location. Acquisition and centralized corporate operation by ALLIANCE AVIATION GROUP LLC represents the most notable ownership detail on public record for this airframe.

The Gulfstream G-IVSP airframe N455WG is configured to seat 22 passengers, indicating a high-density corporate or head-of-state style interior layout tailored for large groups or charter operations rather than single-family corporate VIP fit-outs. Typical mission profiles supported by the airframe’s specifications include transcontinental and transoceanic sectors up to 4,220 nm at cruise speeds near 476 kts and operating altitudes to 45,000 ft, aligning with high-speed, long-range executive transport. Avionics fit and internal finish are not published in the supplied data; maintenance considerations for this airframe emphasize the twin TAY 611SER powerplants, each producing 12,450 lbf, which drive scheduled heavy maintenance and engine shop visits consistent with Gulfstream aftermarket cycles.

The Gulfstream G-IVSP represented by N455WG sits within the long-range, large-cabin business jet segment, offering a blend of speed, altitude capability, and passenger capacity suited to sizeable corporate or charter missions. Competing models typically include large-cabin derivatives from Bombardier and Dassault in similar vintage classes; buyer and charter demand for a 1992 G-IVSP depends on maintenance history, interior refurbishment, and engine program status. Resale and upkeep considerations for this airframe focus on the lifecycle of the TAY 611SER engines and the cost of upgrades to avionics and cabin systems to maintain market competitiveness.
