N437UP

This entry describes the specific airframe bearing registration N437UP, a freighter-converted Boeing 757 built in 1994 with manufacturer serial number 25468. The airframe is a Boeing 757-24A(PF) originally produced by Boeing and is registered in the US for commercial cargo operations. It is owned by UNITED PARCEL SERVICE CO (a corporation based in Louisville, KY, US), which serves as the long-term operator and home-base affiliate for the type; ownership and registration are held in Louisville, Kentucky. Public records do not publish a contemporary market valuation or detailed condition report for this specific ship, and no other registry actions are noted in the provided data.

As a passenger-to-freighter conversion indicated by the (PF) designation, this Boeing 757-24A(PF) is configured for cargo operations under its corporate owner, with a main-deck freighter layout tailored to unit load devices and bulk cargo rather than passenger seating. Typical mission profiles for this airframe involve medium- to long-range domestic and transcontinental cargo sectors consistent with a 3,900 nm range and a cruise speed near 458 kts, operating out of its owner’s Louisville hub. Avionics and systems fit are consistent with freighter modifications customary to the 757 freighter fleet, and routine maintenance considerations emphasize airframe life, roll-on/roll-off main-deck systems and the RB211 engine maintenance cycles specific to Rolls-Royce powerplants.

The Boeing 757-200 freighter derivatives occupy a niche for high-capacity narrow-body cargo missions where runway performance and medium-long range are required; this Boeing 757-24A(PF) with Rolls-Royce RB211-535E4 powerplants offers thrust and performance supporting 42,000 ft ceilings and efficient cruise. Competing types in the same market niche include other converted narrow-body freighters, with demand driven by integrators and express carriers that value payload-range and reliability. Resale and maintenance considerations for this airframe focus on engine shop visit history for the RB211 series, structural fatigue checks on a mid-1990s airframe, and the market for converted 757 freighters among large parcel operators.
