Mammoth Freighters announced the delivery of its first converted Boeing 777-200LRMF (MSN 32222 / N703DN) to US lessor Jetran LLC. It is the first unit of an order for more than two dozen freighters of this type placed by Jetran, 13 of which will operate on DHL’s global network.
The delivery comes shortly after the aircraft’s public debut at the Farnborough International Airshow (July 2026), where it generated strong interest from airlines, lessors and cargo operators. The aircraft, converted at STS Aviation Services’ facility in Manchester (UK), wears DHL’s livery and is destined for DHL Air UK, the East Midlands-based cargo airline that operates for the DHL Express network.
According to Mammoth’s statement, additional deliveries are expected in the coming weeks, including units for DHL and Qatar Airways Cargo. DHL confirmed at Farnborough that it has a total of 13 777-200LRMFs (an expansion of the original nine-aircraft order announced in 2023) and plans to put four of them into service during 2026 as part of the modernization of its long-haul fleet.

Bill Tarpley, CEO of Mammoth Freighters, said the delivery “is a defining moment” for the company: “Seeing this aircraft move closer to entering commercial service with DHL demonstrates the enormous momentum behind our 777 program. We are proud to deliver this historic freighter to Jetran and deeply grateful for their trust as we continue to supply the market with one of the most capable converted cargo platforms in the world”.
Jordan Jaffe, CEO of Jetran, added: “Receiving our first Mammoth 777 freighter represents much more than fleet expansion: it validates the exceptional engineering and production quality of this program as it enters active service with DHL. We extend our sincere thanks to DHL for its close collaboration and to the entire Mammoth Freighters team for their technical excellence and tireless dedication. This delivery is the culmination of years of joint innovation, and we look forward to seeing these freighters bring lasting value to operators around the world”.
The 777-200LRMF is a passenger-to-freighter (P2F) conversion developed by Mammoth Freighters, a company founded in December 2020 and backed by funds managed by affiliates of Fortress Investment Group. The company holds a Boeing license to perform 777 modifications and is building a global conversion network with capacity for up to nine production lines: five at Aspire MRO (Fort Worth, Texas), two at STS Aviation Services (Manchester, England) and two at STAECO (Qingdao, China).
The delivered aircraft (N703DN) is a Boeing 777-200LR built in 2009 and originally operated by Delta Air Lines. After being placed in storage, it was acquired by Jetran and converted in Manchester, where the widest main cargo door in its class, a reinforced floor and an advanced cargo handling system (Collins Aerospace) were installed. The FAA granted the Supplemental Type Certificate (STC) in April 2026, with a certified payload of approximately 104,800 kg (231,000 lb) and a range of about 4,800 nm (nearly 8,890 km) at maximum payload — figures very close to those of the factory-built Boeing 777F, but at a lower acquisition cost.
Jetran acts as the launch customer and principal leasing customer. In addition to the 13 aircraft for DHL, Qatar Airways Cargo has an agreement for five units (considered the program’s operational launch customer), and commitments with Ethiopian Airlines have also been mentioned. Mammoth is advancing in parallel with the 777-300ERMF version, whose certification is expected by the end of 2026.
Demand for long-haul freighters remains high, driven by e-commerce growth, the need to modernize fleets (DHL is looking to replace older aircraft) and delays in next-generation freighters (777-8F and A350F). With this first delivery, Mammoth Freighters moves from the certification and demonstration phase to production and commercial entry into service, consolidating its position in the converted widebody segment.
