U.S. Military Seeks Autonomous Freighters for Logistics
The U.S. military is actively pursuing the development of autonomous freighters capable of transporting supplies through perilous waters, as outlined in a recent solicitation from the Defense Innovation Unit (DIU). These robotic vessels are designed not only to carry essential cargo but also to self-scuttle to evade capture if necessary. The initiative aims to address significant logistical challenges faced by the Department of Defense in contested environments.
Innovative Solutions for Contested Logistics
The DIU’s solicitation highlights the pressing need for innovative logistics solutions in increasingly hostile littoral zones. The document warns of a “littoral contested logistics challenge,” emphasizing that distributed operations in these areas are vulnerable to threats targeting logistics capabilities. These threats can severely hinder the operational effectiveness of military forces. To combat this issue, the DIU is looking for cost-effective and expendable robotic freighters that can be deployed within 180 days of contract award.
While the solicitation does not specify the exact size of these vessels, it mandates a minimum cargo capacity of nine tons. This indicates that the freighters will be significantly smaller than traditional commercial and military ships, which typically have capacities in the tens or hundreds of thousands of tons. The design requirements include a low-profile form factor to minimize detection risks and the ability to be transported by a standard commercial tractor-trailer.
The cargo these vessels will carry includes standard warehouse pallets, Pallet Containers (PALCONs), and Joint Modular Intermodal Containers (JMICs). The freighters must be capable of transporting six 3,000-pound JMICs or two 5,100-ton containers. With a minimum speed of 12 knots while fully loaded, these autonomous ships will be slower than many commercial vessels but are expected to operate effectively in challenging sea conditions, capable of traveling 1,000 to 2,000 miles in waves up to 13 feet high.

Advanced Navigation and Security Features
As with any autonomous maritime technology, navigation and collision avoidance are critical concerns. The Pentagon anticipates that these vessels will operate in congested ports and waterways, often in environments where GPS signals may be jammed. To address these challenges, the freighters will be equipped with GPS and active sensors, as well as passive sensing capabilities for situations where communication is compromised.
Before the completion of prototyping, companies must demonstrate reliable Position, Navigation, and Timing (PNT) capabilities in environments with denied, degraded, intermittent, and limited communications. The guidance systems must allow for reprogramming while at sea, and human operators should have the ability to take remote control of the vessels when necessary.
Security is also a significant concern, as the Pentagon aims to prevent hostile actors from hijacking these robotic vessels. The solicitation specifies that the ships must be resistant to tampering while in transit and must have the capability to be remotely scuttled if needed. This multifaceted approach aims to ensure that the U.S. military can maintain logistical support even in the most challenging operational environments.
