Unmanned Surface Vessels
We have the technology for unmanned operations
The maritime domain is evolving rapidly. Unmanned systems, digital technologies, and networked operations are reshaping naval missions worldwide. As navies expand the use of Unmanned Surface Vessels (USVs) and Medium-Sized Unmanned Surface Vessels (MUSVs), reliable mobility becomes a critical enabler of operational success.
While discussions around unmanned systems often focus on sensors, artificial intelligence, and communications, every mission ultimately depends on one fundamental capability: propulsion. Without reliable mobility, there is no endurance, no presence, and no mission readiness.

Automation and digital intelligence
For more than 25 years, RENK has been developing and delivering advanced gear control and automation solutions for maritime applications, supporting naval and commercial vessels across a wide range of propulsion configurations. This expertise encompasses the integration and control of mechanical, electrical, and hybrid propulsion systems, ensuring safe, efficient, and dependable vessel operation throughout all mission phases. As unmanned naval platforms continue to evolve, proven propulsion automation becomes a key for operational independence.
By combining decades of maritime automation experience with deep naval engineering expertise, RENK provides the control and automation foundation that allows future unmanned vessels to operate reliably, consistently, and with the level of confidence demanded by mission-critical naval operations.
Condition monitoring Condition monitoring Condition monitoring involves continuously monitoring technical systems to detect deviations or damage early on. and predictive maintenance
Unmanned platforms require visibility into system health and performance. RENK supports this through advanced condition monitoring and predictive maintenance technologies that provide:
- Continuous system monitoring
- Early fault detection
- Reduced unplanned downtime
- Improved fleet availability
- Optimized maintenance planning
For unmanned vessels operating far from support facilities, this capability becomes a critical contributor to mission assurance.
Our technologies are developed to meet the highest military standards, ensuring secure, dependable, and resilient operation even in demanding environments. Customers worldwide trust our expertise because we combine proven engineering, deep domain knowledge, and a long-standing commitment to safeguarding mission-critical systems.

Ready for the digital fleet of the future
The next step in maritime autonomy is connected and learning fleets. Through the future integration of performance-based digital twin technologies, RENK aims to support fleet optimization, operational planning, maintenance forecasting, and mission effectiveness on an entirely new level.
Digital twins will transform data into actionable insights, allowing operators to simulate performance, anticipate maintenance needs, and continuously optimize operational outcomes. Every vessel will become part of a larger connected ecosystem. Every mission will generate knowledge. Every fleet will become smarter over time.
By transforming operational data into actionable insights, future unmanned fleets will become more efficient, more resilient, and increasingly capable over time.
Powering the future of uncrewed maritime operations
Unmanned maritime systems are becoming a cornerstone of future naval operations. They extend operational reach, strengthen deterrence, enhance maritime security, and reduce risk to personnel.
Behind every unmanned mission stands a propulsion system that ensures mobility, endurance, and reliability.
