The Boeing 777-300ERSF will be the American manufacturer’s latest development of its popular 777F freighter. What sets this model apart is the fact that the aircraft will not be newly built. Instead, they will be converted from retired 777-300ER passenger airliners. It has been announced today that American cargo airline Kalitta Air will be the type’s launch customer. //

In a press release published in October 2019, GECAS (General Electric Capital Aviation Services) and IAI (Israel Aerospace Industries) announced the launch of the Boeing 777-300ERSF program. Utilizing retired Boeing 777-300ER passenger airliners, the program will see the otherwise redundant aircraft be converted to specialist freighters.

The ERSF suffix stands for “Extended Range Special Freighter.” The type will be known colloquially as ‘The Big Twin.’ This nickname pays tribute to the fact that the aircraft will be the world’s “largest-ever twin-engine freighter.”
