Mammoth Freighters has secured Supplemental Type Certificate (STC) approval from the Federal Aviation Administration for its Boeing 777-200 passenger-to-freighter (P2F) conversion program, marking a major milestone in widebody cargo aircraft development.
The certification clears the way for Mammoth to begin commercial deployment of converted Boeing 777-200 freighters, enabling airlines and cargo operators to expand long-haul capacity amid sustained demand for air freight.
The 777-200 P2F program is designed to offer high payload capability and fuel efficiency, making it an attractive option for operators seeking to replace older freighter fleets. The converted aircraft is expected to cater to growing demand across transcontinental and intercontinental cargo routes.
Industry analysts note that the addition of more 777 freighters will help address capacity constraints in the widebody segment, particularly as e-commerce growth and supply chain diversification continue to drive air cargo volumes.
Mammoth Freighters said it is working with global partners to ramp up conversion slots and deliver aircraft to customers in the coming months. The company also highlighted strong market interest in the platform, with multiple orders and commitments already in place.
The approval underscores the broader trend of passenger-to-freighter conversions gaining traction, as airlines and lessors look to maximize asset utilization while meeting evolving cargo market requirements.
With the STC now in place, Mammoth is positioned to become a key player in the next generation of widebody freighter conversions, competing in a segment that is seeing renewed investment and long-term growth potential.
