6 METER SWIFT
SEA- STALKER (S3)
Unmanned Surface Vehicle
Dominating Asymmetric Warfare
Cyber Hardened
Overview
The Swift-Sea-Stalker (S3) is designed for high endurance, survivability, and mission flexibility, featuring a durable aluminum frame with a self-scuttling hull. Powered by diesel and equipped with multi-spectral sensors, BLOS communications, and a modular mission payload bay, this autonomous USV enables cooperative operations and multi-day navigation with a range of 1,200 NM and a payload capacity of 1,250 lbs. The S3 and its trailer can fit into a 20’ TEU container and are available as a kit or fully assembled, offering flexibility for rapid deployment.
The S3’s modular open system architecture, plug-and-play command and control (C2), and advanced ISR capabilities are designed to support expeditionary maritime operations, aligning with Joint Warfighting Concepts (JWC). The S3 complies with NATO Standardization Agreements (STANAG) 4586 and the Joint Architecture for Unmanned Systems (JAUS) protocol.

Militarized Unmanned and Minimally Manned Vessels
Swiftships design and constructs of fully autonomous military vessels, and offers commercial platform conversion to militarized unmanned/minimally manned vessels. We have developed many variants of our Fast Supply Vessels (FSVs), not only for full autonomy, but also for minimally manned or remote operations of the craft.
Our primary example is an offshore patrol vessel previously called Riley Claire (aka Nomad) that is one of two offshore vessels so far converted to autonomous operation. Nomad is being tested by the US Navy in multiple missions. It traveled from the Gulf Coast through the canal to the U.S. West Coast, a total of 4,421 nautical miles, with 98% of that distance in autonomous mode and the Panama Canal in manual mode.
Learn more about Swiftships’ “Autonomous Solutions“, or read “Riley Claire (aka Nomad)” case study.
How can we work together?
Of course, we can build your vessels in our location! But if for some economic or strategic reasons, you choose vessels’ construction at your location – Swiftships can provide you a full support. We have extensive experience working with international clients on co-production programs, and we offer customized solutions to meet your needs. Learn more…
Other Platforms
We design, build, integrate, and maintain naval vessels for multiple missions: from border protection to lower-intensity threat missions and high-demand or high-threat law enforcement scenarios.
