Purpose-Built Systems for USV & UUV Applications
Whether operating above or below the surface, unmanned vessels require precise, efficient, and integrated systems to ensure mission success. SIT provides critical subsystems engineered for durability, autonomy, and performance in harsh marine and combat environments.
Our Defense-Grade Capabilities Include:
STEERING SYSTEMS FOR PRECISION CONTROL
SIT’s hydraulic and electronic marine steering systems are engineering for precision, reliability, and agile maneuverability across a broad range of unmanned vessels. These purpose-built systems ensure seamless control and are optimized for long term durability within minimal maintenance.
LAUNCH & RECOVERY SYSTEMS (LARs)
SIT designs and manufactures custom davits and winch systems for safe and efficient deployment and retrieval of UUVs and smaller USVs from larger vessels. These LARs systems are engineered with survivability and operational safety in mind, delivering smooth launch and recovery cycles even in challenging sea states.
STERN GATES & RAMPS
We design robust stern gate and ramp systems to support launch and recovery of unmanned vessels directly from a mothership. These heavy-duty structural components are engineered to integrate with hydraulic actuation, locking systems, and safety interlocks, enabling secure deployment while underway.
INTEGRATED PROPULSION PACKAGES
SIT offers advanced propulsion and auxiliary system packages designed for hybrid and electric unmanned surface vehicles (USVs). These compact, energy-efficient solutions deliver high power density and precise control, ensuring exceptional endurance and maneuverability—critical for high-performance defense operations.
VALVE AUTOMATION FOR LARGER PLATFORMS
For larger USVs or supporting mothership systems, SIT integrates Emerson valve automation solutions, enabling automated fluid control for ballast systems, fuel management, and hydraulic functions. As an experienced partner of Emerson’s marine and defense-grade components, we ensure full system compatibility and operational reliability.
