KÓPAVOGUR, Iceland : Sweden has taken a major step forward in strengthening maritime security in the Baltic Sea following the successful early delivery of advanced autonomous underwater systems designed to enhance surveillance, mine countermeasures, and subsea situational awareness.
Teledyne Gavia confirmed on Monday that it has delivered the first four GAVIA Autonomous Underwater Vehicle (AUV) systems to the Swedish Defence Materiel Administration (FMV), marking the opening phase of a multi-year procurement program tied to Sweden’s naval modernization and its expanding role within NATO’s northern defense framework. The delivery was completed ahead of schedule and below projected costs, according to officials familiar with the contract.
Sweden Accelerates Undersea Modernization
The acquisition comes as Sweden faces rising security challenges in the Baltic Sea, where dense commercial traffic, shallow waters, and growing concerns over sabotage of undersea infrastructure have placed new demands on naval forces. Since joining NATO, Stockholm has prioritized unmanned and autonomous systems capable of persistent operations without exposing crews to risk.
The GAVIA AUVs are intended to modernize Sweden’s mine countermeasure (MCM) forces while also supporting intelligence, surveillance, and reconnaissance (ISR) missions in contested littoral environments. FMV officials describe the systems as a cornerstone of future undersea operations, enabling the Swedish Navy to monitor critical sea lanes, ports, and offshore infrastructure with greater speed and precision.
Modular Design for Multi-Mission Operations
The delivered GAVIA systems are configured for long-endurance survey and intelligence missions and are built around a modular “plug-and-play” architecture. This design allows operators to rapidly reconfigure the vehicles for different operational roles, including mine detection, seabed mapping, environmental monitoring, and covert reconnaissance.
Each unit is equipped with high-resolution EdgeTech 2205 side-scan sonar for detailed seabed imaging, enabling the detection and classification of naval mines and unexploded ordnance. Optical identification is supported by Teledyne FLIR Blackfly-S cameras, providing visual confirmation of underwater targets in suitable conditions.
Designed for a low logistical footprint, the GAVIA AUVs can be launched from small vessels, rigid inflatable boats, or directly from shore, reducing reliance on specialized mine countermeasure ships and increasing operational flexibility in narrow or shallow waters.
Industrial Cooperation and Domestic Support
Support and lifecycle maintenance for the new AUV fleet will be provided through a service framework developed in cooperation with Teledyne FLIR Sweden, ensuring in-country technical support and sustained operational readiness. Defense officials say the arrangement strengthens Sweden’s domestic defense industrial base while ensuring high availability rates.
“This delivery reflects a close and effective collaboration with FMV and Swedish industry,” said Stefan Reynisson, Vice President and General Manager of Teledyne Gavia. “The GAVIA system is designed to evolve alongside the operational needs of modern navies, particularly in complex maritime environments like the Baltic Sea.”
Contract Scope and Long-Term Outlook
The framework agreement, valued at approximately 190 million Swedish kronor (around $17.5 million), runs through 2028 and includes options for additional systems, capability upgrades, and long-term support services. Further deliveries are expected as Sweden continues to expand its autonomous undersea capabilities.
Defense analysts note that the investment aligns with broader NATO efforts to improve maritime domain awareness and protect critical undersea infrastructure, including communications cables, energy pipelines, and offshore installations.
Teledyne’s Expanding Global Footprint
The Swedish delivery further cements Teledyne’s position as a leading supplier of unmanned underwater systems. As of January 2026, the company reports more than 12,000 APEX profiling floats delivered worldwide, over 1,275 Slocum gliders in service, and 18 navies currently operating GAVIA AUV systems.
More than 600 Teledyne autonomous platforms are now in use by NATO member states, supporting interoperability, joint operations, and allied maritime security.
Strategic Impact in the Baltic Sea
For the Swedish Navy, the arrival of the GAVIA AUVs represents a significant enhancement of undersea awareness at a time of heightened regional tension. By expanding autonomous capabilities, Sweden aims to secure vital sea lines of communication, improve mine countermeasure readiness, and strengthen collective defense in one of Europe’s most strategically sensitive maritime regions.
