About the History of Boeing 777-300ERSF(Special Freighter)

In July 2018, Boeing was studying a 777-300ER freighter conversion, targeted for the volumetric market instead of the density market served by the 777F.After having considered a -200ER P2F program, Boeing was hoping to conclude its study by the Fall as the 777X replacing aging -300ERs from 2020 will generate feedstock.New-build 777-300ER may maintain the delivery rate at five per month, to bridge the production gap until the 777X is delivered.Within the 811 777-300ERs delivered and 33 to be delivered by October 2019, GE Capital Aviation Services (GECAS) anticipates up to 150-175 orders through 2030, the four to five months conversion costing around $35m.

In October 2019, Boeing and Israeli Aerospace Industries (IAI) launched the 777-300ERSF passenger to freighter conversion program with GECAS ordering 15 aircraft and 15 options, the first aftermarket 777 freighter conversion program.In June 2020, IAI received the first 777-300ER to be converted, from GECAS.In October 2020, GECAS announced the launch operator from 2023: Michigan-based Kalitta Air, already operating 24 747-400Fs, nine 767-300ERFs and three 777-200LRFs.IAI should receive the first aircraft in December 2020 while certification and service entry was scheduled for late 2022.
The converted aircraft has a maximum payload of 224,000 lb (101.6 t), a range of 4,500 nmi (8,300 km) and shares the door aperture and aft position of the 777F.It has a cargo volume capacity of 28,900 cu ft (819 m3), 5,800 cb ft (164 m³) greater than the 777F (or 25% more) and can hold 47 standard 96 x 125 in pallet (P6P) positions, 10 more positions than a 777-200LRF or eight more than a 747-400F.With windows plugged, passenger doors deactivated, fuselage and floor reinforced, and a main-deck cargo door installed, the 777-300ERSF has 15% more volume than a 747-400BCF.By March 2023, IAI had completed the 777-300ER first flight, converted for AerCap, as it had a backlog over 60 orders.

Have a nice flight!
