What Mammoth Freighters does
Mammoth Freighters LLC is a private U.S. aerospace company founded in December 2020 and headquartered in Fort Worth, Texas, that designs, develops, certifies, and supports passenger-to-freighter (P2F) conversions of Boeing 777-200LR and 777-300ER aircraft. The company operates as a Boeing Licensee for the 777 platform and holds an FAA Organization Designation Authorization (ODA) that allows it to issue Supplemental Type Certificates, approve technical data, and conduct compliance inspections on transport category aircraft. Its flagship products are the 777-200LRMF and 777-300ERMF freighter conversion programs, differentiated by a proprietary main deck cargo door larger than competitive 777 conversion products and the 747-400F, GE90-110/115 engine fuel efficiency, and commonality with existing 777 fleets across containers, tooling, engines, and training.
The company monetizes primarily through one-time passenger-to-freighter conversion contracts with global air cargo operators, airlines, and aircraft lessors, supplemented by FAA ODA-based certification services for transport category aircraft. Its go-to-market is direct enterprise sales targeting cargo airlines, integrators (e.g., DHL), and leasing companies (e.g., AviaAM). Reported launch and anchor customers include Qatar Airways Cargo, Cargojet, AviaAM Leasing, and DHL. Mammoth operates a global conversion network through its strategic investment in Aspire MRO at Alliance Airport, Fort Worth (778,125 sq ft, seven widebody bays) and a partnership with STS Aviation Services in Manchester, UK (245,522 sq ft), with three additional conversion sites publicly planned. The company is backed by private investment funds managed by Fortress Investment Group LLC.
The business is capital-intensive and at an early commercial inflection point: the 777-200LRMF received FAA Certification on April 8, 2026, and completed its first flight on May 1, 2025. As of the latest disclosed data, Mammoth had a 41-aircraft order book (October 2022) augmented by a subsequent nine-aircraft DHL commitment (April 2024), representing a substantial forward pipeline. With 51–100 employees and engineering offices in Escondido and Seattle alongside its Fort Worth headquarters, the company is scaling conversion throughput to convert its order backlog into recognized revenue.
