USTRANSCOM seeks industry insights on Next-Generation Oversized Cargo Aircraft

The U.S. Transportation Command (USTRANSCOM) released a Request for Information (RFI) document on Wednesday that explores future options for large and oversized air cargo transportation services critical to Department of Defense (DoD) operations.

The RFI targets commercially developed aircraft capable of transporting military and space-related cargo exceeding standard dimensions. Specifically, USTRANSCOM seeks details on planes under development as of June 2025 that could carry payloads up to 300 feet in length—such as space launch vehicles—by Dec. 31, 2035. These aircraft would supplement existing capacities to meet the DoD’s logistical and readiness requirements, both immediately and in the long term.

The Air Force currently operates the following aircraft for strategic and oversized cargo transport: 

• C-5M Super Galaxy: The largest aircraft in the Air Force inventory, capable of carrying massive payloads, including M1 Abrams tanks or large helicopters, over intercontinental distances. It features both nose and aft doors for simultaneous, drive-through loading and unloading.
• C-17 Globemaster III: A versatile aircraft that offers a balance between strategic and tactical airlift, known for its ability to operate from shorter or less prepared runways than the C-5. It is a core component of the U.S. military's airlift fleet.

Key Requirements and Timeline

The proposed aircraft must enter service no later than 2035 and provide between 2,000 and 7,500 flight hours over 2–5 years. Additionally, the RFI emphasizes collaboration with civilian aviation sectors, reflecting a strategic push to leverage commercial innovation for defense needs.

Implications for the Global Aerospace Industry

The RFI opens opportunities for international aerospace firms developing next-generation heavy-lift or specialized transport aircraft. Companies with projects in advanced cargo planes, modular transport systems, or reusable space vehicle carriers may find alignment with the DoD’s vision. Potential contenders could include firms exploring ultra-large freighters, aerial cargo platforms, or customized solutions for oversized payloads.

Strategic Context

While the RFI does not signal an immediate procurement decision, it lays the groundwork for future contracts that could redefine air cargo standards.

Companies have until Jan. 29 to respond to the RFI announcement.
