Mammoth Freighters delivers first Boeing 777-200LR converted freighter for DHL

Mammoth Freighters has reached a major milestone in its passenger-to-freighter conversion programme with the delivery of its first Boeing 777-200LRMF to Jetran.

The aircraft, registered N703DN and with serial number MSN 32222, is the first of more than two dozen 777-200LRMF freighters ordered by Jetran.

Thirteen aircraft from the programme are scheduled to enter revenue service within DHL Express’ global network in the coming years, with four more arriving by the end of 2026.

At a special handover event, DHL said the converted 777 was an important addition to its long-haul fleet, highlighting the aircraft’s combination of range, payload and operational flexibility.

The first aircraft is destined for DHL Air UK, where it will become part of DHL Express’s international long-haul network.

The delivery comes only weeks after the aircraft made its public debut at the Farnborough International Airshow in July, where it sat on static display the entire week welcoming visitors.

For Mammoth Freighters, the handover represents the transition of the 777-200LRMF programme from development and certification into commercial operation.

The company has developed the conversion to transform passenger 777-200LR aircraft into dedicated freighters capable of carrying cargo on the main deck.

The modification includes the installation of a large main-deck cargo door, a reinforced main-deck floor and a modern cargo-handling system.

The aircraft delivered to Jetran was originally built in 2009 and previously operated by Delta Air Lines. It was subsequently converted at STS Aviation Services in Manchester, United Kingdom, as part of Mammoth’s growing international production network.

Following the conversion, the aircraft emerged as one of the first examples of the new 777-200LRMF configuration and was painted into full DHL colours ahead of its entry into service.

Why the Boeing 777-200LR works as a freighter

The 777-200LR is an especially attractive platform for conversion because of its long-range capability and large fuselage. According to published programme information, the converted aircraft has a certified payload of approximately 104,800 kilograms and a range of around 4,800 nautical miles at maximum payload.

Those figures place the 777-200LRMF firmly in the heavy long-haul freighter category and give operators a twin-engine alternative to older four-engine cargo aircraft.

For DHL, the arrival of the Mammoth-converted aircraft is part of a wider strategy to modernise its intercontinental fleet. DHL originally announced an order for nine Mammoth-converted 777-200LR freighters from Jetran in April 2023.

At the time, the company said the aircraft would help replace older Boeing 747 freighters and provide an efficient bridge towards newer-generation aircraft such as the Boeing 777-8F and Airbus A350F.

The Boeing 777LRMF marks an important evolution in the global freighter arena

The decision to use converted aircraft also reflects the economic and environmental considerations facing the air-cargo industry. Rather than manufacturing an entirely new aircraft, a passenger-to-freighter conversion gives an existing airframe a second operational life.

DHL has described the approach as part of its wider sustainability strategy, while also emphasising the operational benefits of the Boeing 777 platform.

By retaining the existing airframe and engines, the conversion can provide additional cargo capacity without the manufacturing footprint associated with building a completely new freighter.

Jetran occupies a central position in the programme as Mammoth’s launch lessor and a major customer for the converted aircraft. The company’s order covers more than two dozen 777-200LRMFs, with aircraft allocated to several international operators.

Further deliveries from the Jetran order book, including aircraft intended for DHL and Qatar Airways, are expected as Mammoth increases production.

The first delivery is therefore significant beyond the individual aircraft. Mammoth is developing a broader global conversion network, with production and conversion capacity planned across facilities in the United States, the United Kingdom, and China.

The company is also progressing with the 777-300ERMF, another passenger-to-freighter conversion intended to broaden its product offering.

Global demand continues to rise for widebody freighters

For DHL, the first 777-200LRMF has arrived at a time when demand for reliable long-haul cargo capacity remains strong. Express operators need aircraft capable of moving large volumes of time-sensitive freight between continents while keeping operating costs under control.

The Boeing 777’s combination of range, capacity, and twin-engine efficiency makes it well suited to that mission.

The delivery of N703DN to Jetran is consequently more than a routine change of ownership. It marks the first commercial delivery of Mammoth’s 777-200LRMF programme and the beginning of a new chapter for an aircraft type that once carried passengers and will now carry thousands of tonnes of international freight.

For Mammoth Freighters, the delivery represents a validation of years of engineering and development. For Jetran, it begins the delivery of a substantial new freighter portfolio. And for DHL, it provides another long-range workhorse for its global express operation.

The first 777-200LRMF may therefore be just one aircraft, but its delivery signals the start of a much larger transformation in the widebody freighter market.
