N673UP

This airframe, registered as N673UP, is a Boeing-built freighter originally manufactured in 1971 with manufacturer serial number 20325. The airframe is a Boeing 747-123(SF) variant and is owned and operated by the US corporation Kalitta Air, with its operational base in the United States. The type has been converted to main-deck cargo (SF) on this registration, and the aircraft carries US registration status. Public valuation or detailed condition reports for this specific airframe are not published.

This airframe’s cabin has been converted to a main-deck cargo configuration; there is no passenger cabin and it operates as a single-main-deck freighter. Avionics fit and specific onboard systems for this airframe are not published. Operated by US-based Kalitta Air, the aircraft is typically employed on long-haul, transcontinental and intercontinental cargo missions consistent with its 5,300 nm range and high-capacity main-deck freight role. Maintenance considerations for this 1971-built airframe reflect the typical heavy-airframe and legacy-engine regimen associated with early-production 747-series aircraft, including requirements unique to JT9D-powered airframes and converted freighter structural inspections after conversion.

The Boeing 747-123(SF) of this serial is a member of the early 747 family tailored to long-range, high-capacity payload operations; with four JT9D-7A engines providing 46,500 lbf thrust each, it occupies a niche for large-volume, long-range cargo carriage. Competing market types include other widebody freighters of similar vintage and converted 747 variants; buyer demand and charter appeal are influenced by airframe age, conversion status, and the availability of maintenance resources for legacy JT9D engines. Resale and continued operation considerations for this airframe hinge on continued operator support, spare parts for legacy systems, and the commercial viability of older large freighters in modern cargo fleets.
