Mammoth Freighters LLC (Mammoth) revealed Cargojet Airways Ltd (Cargojet) is the launch customer for their new 777-200LR freighter conversion programme, with the signing of a sales agreement for two initial 777-200LRMF freighters. The aircraft is expected to begin the conversion process in mid-2022 with delivery to Cargojet in the second half of 2023.

MSN 29747, the prototype (conformity) article for certification, will be the first aircraft delivered to Cargojet. Cargojet has additional options for two 300ERMFs and two additional 200LRMFs. 

Mammoth Co-CEO Bill Tarpley said, “We are grateful and excited that Mammoth has been selected by Cargojet to bring this conversion to market and demonstrate the significance of our product to the world. This is the next generation of converted freighters that have improved on-wing performance while using less fuel and emitting less carbon than the current aging widebody fleet.”

Cargojet is Canada’s leading provider of time-sensitive premium air cargo services to all major cities across North America, providing dedicated ACMI and International Charter services and carries over 25,000,000 pounds of cargo weekly. Cargojet operates its network with its own fleet of 31 aircraft.

The addition of Mammoth’s 777-200LRMF freighter completes the Cargojet fleet profile. The Mammoth 777 is tomorrow’s freighter today; a fuel-efficient, heavy lifting, high-volume, long-range aircraft operating with clean, efficient, and reliable GE90-110/115B engines.
