The 747-400ERF is the freight version of the -400ER, launched on 30 April 2001. The -400ERF was delivered to Air France (via ILFC) on 17 October 2002. The 747-400ERF has a maximum payload of 248,600 pounds (112,760 kg)(maximum takeoff weight is 910,000 pounds) and offers the cargo airline the choice of either adding 22,000 pounds (9,980 kg) more payload than other 747-400 freighters, or adding 525 nautical miles (972 km) to the maximum range. It has a maximum range of 9,200 km, about 525 km farther than other 747-400 freighters, and has a strengthened fuselage, landing gear and parts of its wing, along with new, larger tires.
Boeing has seven 747-400ERF aircraft yet to be delivered in June 2008. The new 747-8 Freighter will have more payload capacity but less range than the 747-400ERF.
