Saab has secured a contract from an undisclosed European NATO member for its Sirius passive sensor system, which is designed to support signals intelligence (SIGINT) and surveillance missions, along with related support services.
The agreement is valued at approximately €130 million ($153 million), with system deliveries planned through 2030. Sirius combines communications and electronic intelligence sensors to deliver both tactical situational awareness and strategic intelligence across air, land, and maritime domains, enabling multi-domain surveillance and joint SIGINT operations.
Earlier this year, Saab revealed plans to establish a new production facility in Finland to expand manufacturing of Sirius Compact, a smaller and more adaptable version of the system optimized for tactical deployment and easier integration across diverse platforms. The facility will support high-volume production as global demand for advanced sensor and electronic warfare technologies continues to increase.
Sirius can be fielded as a fully integrated system or in modular configurations, allowing the integration of Saab or third-party sensors to meet specific customer requirements, including distributed and networked sensor architectures. The system is engineered to collect signals across a broad radio frequency spectrum with high sensitivity and accuracy, enabling detection and analysis of radar and communications emissions in complex electromagnetic environments.
Data gathered by Sirius is processed and disseminated covertly to support operational decision-making. Automated classification and processing tools reduce operator workload, enabling persistent surveillance with minimal personnel. Scalable data fusion and open interfaces further allow seamless integration with existing platforms and command-and-control networks.
