747-400F

Cargolux 747-400F with nose door open.

The 747-400F (Freighter) is an all freight version which uses the fuselage design of the 747-200F. The model's first flight was on May 4, 1993, and it entered service with Cargolux on November 17, 1993. Major customers included Atlas Air, Cargolux, China Airlines, Korean Air, Nippon Cargo Airlines,Polar Air Cargo, and Singapore Airlines. The −400F can be easily distinguished from the passenger −400 by its shorter upper-deck hump.

The 747-400F has a main deck nose door and a mechanized cargo handling system. The nose door swings up so that pallets or containers up to 40 ft (12 m) can be loaded straight in on motor-driven rollers. An optional main deck side cargo door (like the 747-400M (Combi)) allows loading of dimensionally taller cargo modules. Boeing delivered 126 Boeing 747-400F aircraft with no unfilled orders as of November 2009.^[3] The last −400F was delivered to Nippon Cargo Airlines.
