Product Development and System Engineering

Tethys Systems company philosophy is based on employing highly-skilled system and development engineers, offering more than 100 man-years experience within international Naval projects. The team of dedicated professionals has substantial Naval defence expertise.

Products, Overhaul and Modernisation

Tethys Systems offers a wide range of fire control systems and solutions specifically designed for naval applications and to meet both emerging and constantly evolving challenges posed by current and future naval threat scenarios. Product assembly, as well as overhaul and modernizations are done in our own premises in Switzerland or at customer premises worldwide. More information

System Integration and Technical Assistance

Tethys Systems possesses a wealth of experience in integration of systems from a multitude of suppliers and a proven track-record of bringing these systems into service with many customer navies. Our team of experts continues to provide world-class technical assistance in support of many on-going naval projects.


Tethys Systems has specifically refrained from developing its own production facilities for mechanical, electro-mechanical and electronic components as this generates an unnecessary overhead and inflexibility in terms of fulfilling local work share requirements. Instead, Tethys Systems relies on close cooperation with Swiss high-tech companies. Customers profit thereby from high flexibility, on-time delivery and highest quality. More information


High-tech systems require a high level of know how from their users. Comprehensive training services are therefore an indispensable part of the Tethys Systems philosophy. Tethys offers high quality customer training services for its products. Depending on the customerís requirements and needs, the training programs can be tailor-made to suit the situation.

Integrated Logistic Support (including spare parts, technical manuals and support equipment)

Logistics concepts are defined jointly with the customer for ideal operation and logistics support of the systems in accordance with the customer mission profile. ILS addresses the aspects of supportability not only during acquisition, but also throughout the operational life cycle of the system. The goal of our approach is to minimise the Total Cost of Ownership for the customer and to maximise availability and reliability of Tethys Systems products.
