Mammoth Freighters Delivers First 777-200LRMF to Jetran

Mammoth Freighters LLC delivered its first converted Boeing 777-200LRMF freighter to aviation leasing company Jetran LLC on August 21, 2026, marking the transition of the passenger-to-freighter (P2F) program into active commercial service.

The aircraft, bearing manufacturer serial number (MSN) 32222 and registration N703DN, was handed over at Mammoth’s headquarters in Fort Worth, Texas. According to a company press release, the freighter will enter revenue service with DHL Air UK, a United Kingdom-registered all-cargo airline based at East Midlands Airport (EMA). The delivery follows the program’s Federal Aviation Administration (FAA) supplemental type certification awarded on April 8, 2026.

Fleet expansion and DHL operations

Jetran has ordered more than two dozen 777-200LRMF conversions from Mammoth Freighters. Of that total, 13 aircraft will be placed into revenue service with DHL as part of the logistics provider’s intercontinental fleet modernization strategy.

Jetran Chief Executive Officer Jordan Jaffe stated the delivery validates the engineering and production quality of the program as it enters active service.

“This delivery is the culmination of years of joint innovation, and we look forward to watching these freighters deliver enduring value for operators worldwide,” Jaffe said.

Mammoth Freighters Chief Executive Officer Bill Tarpley noted the momentum behind the 777 program following the aircraft’s public debut at the Farnborough International Airshow between July 20 and July 24, 2026.

“We are proud to deliver this milestone freighter to Jetran and deeply appreciate their trust as we continue supplying the market with one of the world’s most capable, converted cargo platforms,” Tarpley said.

Production scale and market footprint

Mammoth Freighters, founded in December 2020, is developing up to nine global production lines to support its conversion programs. These include five lines in Texas, two in the United Kingdom, and two in China. Mammoth is also currently pursuing FAA certification for its larger Boeing 777-300ERMF conversion program.

While DHL is the operator of the first delivered aircraft, Qatar Airways Cargo was named the launch customer for the 777-200LRMF on May 2, 2025, with an agreement to take five aircraft via Jetran.

Recent test flight investigation

The delivery follows a separate event involving a different Mammoth-converted Boeing 777-200LRMF (N705DN) painted in Qatar Airways Cargo livery. On June 24, 2026, that aircraft performed a low pass at Horseshoe Bay Resort Jet Center in Texas. The FAA is currently investigating the incident.

In a June 25 statement, Mammoth Freighters clarified that the aircraft was owned and operated by Jetran on a pre-delivery test flight, and that neither Mammoth nor Qatar Airways pilots were in control of the aircraft during the event.

AirPro News analysis

We view the first delivery of the 777-200LRMF as a critical milestone for Mammoth Freighters, proving the company’s ability to execute a complex P2F conversion and transition into serial production. Securing DHL as the initial operator provides immediate operational credibility. While the June 2026 test flight incident involving a different airframe generated unwanted attention, the successful handover of N703DN keeps the core conversion program on track. The planned expansion to nine global production lines indicates strong anticipated demand for twin-engine widebody freighters as older platforms face retirement.
