Moving equipment, sensors, and unmanned systems across land–sea boundaries has long been a logistical bottleneck. Most platforms are built for either terrain or water, and shifting payloads between them slows operations and limits flexibility. A new amphibious vessel called Alligator aims to change that by combining autonomous mobility with multi-domain transport and real-time coordination capabilities.
The core challenge addressed by the vessel is the lack of a single platform that can move seamlessly from shore to open water while carrying substantial payloads. Traditional amphibious craft require crewed operation and cannot independently deploy underwater assets. The vessel introduces an autonomous alternative designed to handle tactical logistics without relying on fixed control centers or large surface ships.
According to NextGenDefense, the vessel can transport more than 1,500 kilograms of cargo, including weapons, sensors, and mission equipment, and can operate for over 550 nautical kms at speeds reaching 74 kmph. Its hybrid role expands beyond logistics: The vessel also serves as a launch and recovery platform for unmanned underwater vehicles, enabling rapid deployment of subsea sensors or autonomous systems directly from the surf zone.
To enable multi-platform coordination, the vessel integrates with SeaSphere, Skana’s mission-planning and control framework. SeaSphere allows the vessel to share data with surface and underwater systems in real time, synchronizing routes, alerts, and task assignments. This interoperability extends an existing fleet of autonomous platforms—including Bullshark and Stingray—designed for distributed operations.
For defense and homeland-security organizations, a vessel like this provides a way to conduct littoral logistics, reconnaissance support, and unmanned-system deployment without relying on port infrastructure. It can move ashore, deliver payloads, and return to sea autonomously, reducing the exposure of human crews and improving mission tempo. In contested environments, its ability to operate without a central control hub also enhances resilience against disruptions.
The vessel’s modular architecture supports human-operated, remotely-piloted, or fully autonomous missions. The vessel is engineered to reconfigure quickly for different tasks, allowing operators to switch between payload types or mission profiles on short notice.
By merging amphibious mobility, autonomy, and underwater integration in a single hull, the vessel demonstrates how future fleets may rely on distributed, unmanned assets that work together across domains—delivering faster, more adaptable operational support in dynamic maritime environments.
