N37WH

This entry describes airframe N37WH, a Gulfstream-built business jet completed in 1994 with manufacturer serial number 1243. The airframe is a Gulfstream G-IV SP variant identified as Gulfstream G-IV (G-IV SP) and carries U.S. registration N37WH. Owned and operated by NORTHROP GRUMMAN SYSTEMS CORP, a corporation based in El Segundo, CA, US, the aircraft has been maintained in corporate service and is recorded with a valuation of $3,000,000. Registry and valuation highlights indicate a mature airframe representative of mid-1990s long-range business jets with continued corporate operational use.

The configuration of N37WH supports a high-density corporate layout with 22 seats, consistent with mission profiles emphasizing personnel transport and company internal logistics rather than ultra-luxury executive fit. Typical operations for this airframe and operator profile include transcontinental and transoceanic transfer missions within the aircraft’s 4,220 nm range and cruise performance near 459 kts, operating from the operator’s base in El Segundo, CA. Avionics and interior specifics are not published here, but maintenance considerations for a 1994 Gulfstream G‑IV variant operated by a major defense contractor typically emphasize adherence to manufacturer service bulletins and shop visits for the Rolls‑Royce Tay 611 series engines. The aircraft’s service ceiling of 45,000 ft enables high-altitude routing to optimize fuel efficiency and route availability.

The Gulfstream G-IV (G-IV SP) occupies a long-range, mid-size business jet segment characterized by a balance of range and cabin capacity; the type competes historically with late-model offerings from Bombardier and Dassault in similar mission roles. With twin Rolls‑Royce Tay engines producing 12,450 lbf of thrust each, the G‑IV family is noted for reliable cruise performance and long-range capability, making airframes like N37WH suitable for corporate fleet use. From a market perspective, a 1994 airframe valued at $3,000,000 reflects depreciation, lifecycle maintenance investment, and resale factors; buyers and charter operators consider engine shop history, avionics upgrades, and corrosion/structural status when assessing airframes in this age cohort.
