Invariant Corporation has completed an early maritime integration test of its Surface-to-Air Kinetic Engagement system, or STAKE, mounting the capability onto a Textron Systems TSUNAMI unmanned surface vessel during testing at Lake Guntersville, Alabama.
According to the company, the demonstration focused on integrating STAKE onto the TSUNAMI USV platform and validating performance in a maritime environment. The event marked an application of the Advanced Precision Kill Weapon System, or APKWS, in the maritime domain.
STAKE is designed as a modular counter-uncrewed systems capability that can be integrated onto multiple vehicle types. The maritime configuration demonstrated at Lake Guntersville consists of two primary subsystems: “Hunter,” which includes the sensor and laser designation package for target acquisition and tracking, and “Killer,” the precision engagement component. The company said the subsystems operated together in the maritime setting during testing.
“This successful demonstration represents a significant development and reflects Invariant’s position at the forefront of C-UxS innovation as well as kinetic maritime autonomy,” said President Danny Levis. “We are committed to advancing adaptable, high-performance systems that align with the Department of War’s objective to enhance lethality, especially in the maritime domain”.
The TSUNAMI unmanned surface vessel is designed to provide connectivity and operational flexibility across maritime missions while removing personnel from direct risk. Textron Systems describes the platform as built on a Modular Open Systems Approach, enabling integration of various payloads depending on mission requirements. The TSUNAMI family draws on decades of autonomous systems development within the company.
The demonstration forms part of broader efforts across the defense sector to adapt counter-UxS systems for maritime use, particularly as unmanned aerial and surface threats proliferate. While the release characterized the milestone as a significant step forward, further testing and operational evaluation would likely be required before any fielding decisions.
Invariant said the recent event demonstrates the system’s transition from conceptual development toward operationally relevant maritime testing.
