I don’t have access to live tool results in this turn, but I can provide a concise overview based on the topic you asked about: the McDonnell Douglas MD-11F. Core answer

• The MD-11F is the freighter variant of the MD-11, a three-engine (trijet) wide-body aircraft developed from the DC-10 lineage. It features a stretched fuselage, updated engines, improved aerodynamics, and winglets, designed to deliver high cargo capacity on long-haul routes. The MD-11F typically operates with three high-bypass turbofan engines (commonly GE CF6-80C2 family variants) and has a large forward or side cargo door configuration to accommodate a variety of freight types, including pallets and oversized cargo. Typical mission profiles include long intercontinental cargo missions with substantial payloads, relying on its extended range and payload capability to serve major logistics networks.

• In service history, the MD-11F was produced between the early 1990s and the early 2000s, with major operators including FedEx Express and Lufthansa Cargo, among others. It remains in operation with a number of freight carriers around the world, though many have gradually retired or replaced older airframes with more modern freighters. The aircraft is renowned for its cargo capacity, reliability, and adaptability to mixed cargo configurations, though like many aging freighters, individual airframes' economics depend on utilization, maintenance costs, and fuel prices.

• Notable contemporary context: in recent years, some MD-11F aircraft—particularly those operated by major cargo carriers—have remained active due to robust demand in air cargo markets, while others have been retired or stored as fleets modernize. Media coverage in 2025 highlighted incidents involving older freighters, including MD-11F variants in various fleets, which underscores ongoing debates about the economics of operating aging aircraft versus upgrading to newer freighter designs. When incidents occur, investigators typically assess airframe age, maintenance history, and operational conditions as part of the evidence.

If you’d like, I can:

• Break down the MD-11F technical specs (engine types, MTOW, payload capacity, range) with precise figures.
• Compare the MD-11F to contemporary freighters (e.g., MD-11 vs. Boeing 777F or 767F) in terms of payload, range, and operating costs.
• Summarize notable operators and current status of specific airframes (e.g., active fleets, retirement timelines) based on the latest public records.
