Mammoth Freighters LLC was founded in December 2020 to design, develop, convert, and support passenger-to-freighter conversions. Its initial focus centers on Boeing 777 conversions, targeting the 200LR and 300ER variants, and it operates as a Boeing licensee for the 777. The company is building a global production and conversion network, anchored by a Fort Worth, Texas facility, with engineering offices in Escondido, California and Seattle, Washington, and it is based in Orlando, Florida. Its customers include cargo operators and airlines seeking long-range freighter capability, with the conversions intended to enhance efficiency and capacity. In April 2026, ATA Engineering signed Mammoth as a client and began delivering comprehensive test support for the 777-200LRMF conversion as FAA certification progresses.
