Exail has secured a pivotal role in bolstering the capabilities of the Finnish Navy, having supplied crucial navigation equipment for the Helsinki-based Pohjanmaa-class corvettes program. The delivery includes multiple Marins M3 and Phins inertial navigation systems (INS), designed to ensure reliable positioning and orientation during naval operations. These systems are complemented by shock-mounted protection units that enable them to withstand high-impact shocks, thereby enhancing the durability and effectiveness of the fleet in challenging maritime environments.
This delivery is hailed as a significant milestone in the modernization of the Finnish Navy’s fleet, aimed at improving its operational capabilities in the strategically important Baltic Sea region. Each of the corvettes will be equipped with both Marins M3 and Phins INSs, creating a redundant inertial navigation architecture that enhances reliability, especially during complex naval missions where global navigation satellite system (GNSS) signals may not be available.
Exail’s high-precision INS technology is already trusted by over 50 navies worldwide, across a diverse range of naval platforms, including small vessels, aircraft carriers, and submarines. Notably, the INS is designed to maintain precision positioning even during extended operations, with drift remaining as minimal as 1 nautical mile over 360 hours. The advanced systems also dynamically adapt to fluctuating maritime conditions, providing real-time navigation adjustments to ensure consistent performance.
Additionally, Exail’s INS is engineered for stealth operations, significantly minimizing acoustic emissions. This feature enhances security in high-risk areas and allows naval forces to undertake sensitive missions with a greater degree of discretion and efficiency.
Currently, Finland is in the process of constructing four new Pohjanmaa-class corvettes, which are anticipated to become operational by 2029. Each corvette is set to accommodate up to 70 crew members and can achieve speeds exceeding 26 knots (approximately 48 kilometers or 30 miles per hour). These vessels are designed for multi-domain defense, equipped to counter aerial and missile threats. The incorporation of advanced signals intelligence capabilities will further bolster their surveillance and situational awareness capabilities, providing the Finnish Navy with a formidable toolset for modern naval warfare.
