DHL Express has increased its commitment for Mammoth Freighters-converted B777-200LR(MF)s from nine to 13 aircraft, with four due to enter service in 2026. The company said in a press release that the first unit will be placed with DHL Air (D0, Nottingham East Midlands).
The initial aircraft is N703DN (msn 32222), a 2009-built, General Electric GE90-powered B777-200LR formerly operated by Delta Air Lines. Mammoth Freighters converted the airframe at Manchester, equipping it with a main-deck cargo door and advanced cargo-handling systems.
Mammoth Freighters received a supplemental type certificate from the US Federal Aviation Administration for the conversion in April 2026. The company said in July that its first two B777-200LR(MF)s, one for DHL and one for Qatar Airways, were expected to enter commercial service in autumn 2026.
As ch-aviation previously reported, DHL Express originally ordered nine B777-200LR(MF)s from Jetran in April 2023. At the time, deliveries were scheduled to run from 2024 to early 2027 to replace ageing B747 freighter capacity across DHL-owned and partner airlines.
While N703DN is DHL's first converted B777, it is not the programme's first completed unit. The Qatar Airways-earmarked N705DN (msn 29742) completed the programme's inaugural post-conversion flight in May 2025 prior to the STC award in April 2026.
