Mammoth Freighters received FAA certification for its Boeing 777-200LRMF converted freighter, with deliveries to DHL, Qatar Airways, and Ethiopian Airlines.
This article is based on an official press release from Mammoth Freighters LLC.
On April 8, 2026, Mammoth Freighters LLC achieved a major milestone in the aviation logistics sector by securing Federal Aviation Administration (FAA) certification for its Boeing 777-200LRMF (Long Range Mammoth Freighter). According to the company’s official press release, this certification officially clears the passenger-to-freighter (P2F) converted aircraft for immediate commercial service and active deliveries.
The announcement carries substantial weight for the global air cargo market. Jetran, the launch customer for the conversion program, plans to supply these newly certified freighters to a roster of top-tier global operators. The press release confirms that DHL, Qatar Airways, and Ethiopian Airlines are among the end users slated to receive the aircraft. We note that securing such high-profile operators underscores the immediate market demand for efficient, twin-engine widebody freighters.
With the testing phase now concluded, Mammoth Freighters is transitioning directly into active aircraft deliveries. The U.S.-based aerospace company, founded in December 2020 and backed by Fortress Investment Group, operates as an official Boeing Licensee dedicated to converting Boeing 777 passenger jets into heavy-duty cargo aircraft.
Engineering and Production Milestones
Aircraft Specifications
The newly certified Boeing 777-200LRMF is engineered to capitalize on the inherent fuel efficiency and long-range performance of the original 777 airframe. According to the technical details provided by Mammoth Freighters, the converted aircraft features the largest main-deck cargo door in its class. Additionally, the freighter is equipped with a reinforced floor structure designed to support heavy freight and integrates an advanced, flexible cargo handling system optimized for both long-haul and regional operations.
Global Manufacturing Footprint
To meet the anticipated demand for these conversions, Mammoth Freighters is actively building a robust global production network. The company’s press release outlines a capacity for up to seven production lines. Currently, five of these lines are located in Fort Worth, Texas, at Aspire MRO, while two additional lines operate in Manchester, England, through STS Aviation Services UK Limited. Furthermore, the company has indicated planned future expansion into the Asia-Pacific region to support growing international logistics needs.
Industry Impact and Stakeholder Perspectives
Executive Reactions
The successful FAA certification has drawn positive reactions from key stakeholders involved in the program’s development and financing. In the official media release, leadership from Mammoth, Jetran, and Fortress Investment Group emphasized the collaborative effort required to reach this stage.
“This certification reflects years of disciplined engineering, close collaboration with the FAA, and the dedication of our entire team and partners. Approval of the 777-200LRMF underscores the strength of our technical approach and our ability to deliver a high-performance freighter that meets the evolving demands of cargo operators worldwide.”

Jordan Jaffe, CEO of launch customer Jetran, echoed this sentiment, highlighting the value the aircraft will bring to their high-profile clients.
“From the outset, we have had strong confidence in the Mammoth engineering team and their vision for the program. The aircraft’s quality and technical execution have met our high expectations and reflect the strength of the underlying design. We believe the Mammoth conversion will be a competitive and compelling option in the long-haul freighter market and will deliver solid value for Jetran’s customers including DHL, Qatar Airways and Ethiopian Airlines.”

The financial backing for the extensive engineering and certification process was provided by funds managed by affiliates of Fortress Investment Group. Drew McKnight, Co-CEO and Managing Partner at Fortress, framed the achievement as a domestic manufacturing success.
“This certification is a great example of private industry collaborating with the FAA to strengthen American aviation and build a great American company. With a fully integrated U.S.-based production platform, Mammoth Freighters is built to meet sustained global demand for freight aircraft in the decades ahead.”

AirPro News analysis
We view the timing of the 777-200LRMF certification as highly strategic. The global air cargo industry is currently undergoing a massive fleet renewal cycle. As older, less fuel-efficient quad-engine freighters, most notably the Boeing 747, are retired from active service, logistics companies are increasingly turning to twin-engine widebodies. The passenger-to-freighter (P2F) market offers operators massive payload capacities with significantly lower operating costs compared to legacy aircraft.
Furthermore, certifying the 777-200LRMF right now positions Mammoth perfectly to capture this wave of fleet renewals. By offering a highly competitive alternative to factory-new freighters, which often suffer from years-long production backlog delays, Mammoth provides a vital pressure release valve for capacity-constrained cargo airlines. The commitment from “blue-chip” end users like DHL, Qatar Airways, and Ethiopian Airlines serves as a strong market validation of the P2F model for the 777 airframe.
Looking Ahead: The 777-300ERMF
While the 777-200LRMF enters commercial service, Mammoth Freighters is already advancing its next major project. According to the company’s statements, they are currently developing a conversion program for the larger variant, the Boeing 777-300ERMF. Mammoth officially expects to receive FAA certification for this second, higher-capacity model later in 2026, which will further expand their portfolio of widebody freighter offerings.
