N478GS

The airframe with tail number N478GS is a 2002-built Gulfstream IV-SP, serial 1478, manufactured by Gulfstream Aerospace. It is registered in the United States and is owned by L-3 IS LLC, an LLC based in Great Falls, MT, US. The aircraft is configured and certificated for up to 22 passengers although its typical executive cabin layout seats fewer in a standard executive fit. Valuation records indicate a market value of $4,500,000, reflecting airframe age, equipment baseline and current ownership status.

The cabin of this Gulfstream IV-SP is fitted in a typical executive layout accommodating 12–14 passengers in comfortable club and divan arrangements while remaining certificated for 22 pax for higher-density operations. Specific avionics fit and optional mission equipment for this airframe are not published in the provided data; standard G-IVSP installations commonly support long-range executive transport and VIP missions. Operated under ownership of L-3 IS LLC from Great Falls, Montana, the aircraft’s mission profile would typically include transcontinental and transoceanic executive transport within its 4,200 nm range and high-speed cruise of 459 kts. Maintenance considerations reflect the twin Rolls-Royce Tay engines and the logistics of supporting two high-thrust turbofans, with preservation of value tied to systems updates and cabin refurbishments.

The Gulfstream IV-SP (G-IV) occupies the long-range, large-cabin executive jet niche, offering a high cruise speed and 45,000 ft service ceiling suitable for favorable range and performance. Competitors in the market segment include late-model large-cabin bizjets that offer similar transcontinental capability; buyer and charter demand tends to favor examples with updated avionics and well-documented maintenance. Resale and maintenance considerations for this airframe are influenced by its 2002 manufacture date, serial 1478, the twin Rolls-Royce Tay powerplants, and its current valuation of $4,500,000.
