# Subsea robotics and sonar technology developments > Live situation record from CLSTR: https://clstr.news/situations/subsea-robotics-and-sonar-technology-developments > Updated: 2026-08-25T06:09:32.000Z. Sources: 6. Developments: 2. Developments in subsea robotics and sonar technology have focused on enhancing autonomous underwater operations and infrastructure protection. In the United Kingdom, ecoSUB Robotics and Sonardyne demonstrated a system for autonomous underwater vehicle (AUV) launch using seabed-mounted nodes. This technology enables AUVs to navigate without GNSS by receiving acoustic position updates, allowing for coordinated responses across wide areas. Concurrently, maritime firms have expanded their underwater surveillance and navigation capabilities. Kraken Robotics reported significant new orders for Synthetic Aperture Sonar (SAS) and positioning technologies across the defense and energy sectors. Additionally, Kongsberg introduced the Aegir SSA sonar family, which utilizes AI-powered services to provide continuous situational awareness for protecting ports and critical subsea infrastructure. ## Timeline ### 2026-08-25: Maritime technology firms Kraken Robotics and Kongsberg announce new sonar developments Kraken Robotics secured $35 million in new maritime orders, while Kongsberg launched the AI-enabled Aegir SSA sonar family to enhance subsea infrastructure security. 4 sources. https://clstr.news/cluster/maritime-technology-firms-kraken-robotics-and-kongsberg-announce-new-sonar-developments ### 2026-08-20: ecoSUB Robotics and Sonardyne demonstrate autonomous subsea launch ecoSUB Robotics and Sonardyne demonstrated autonomous subsea launch and navigation capabilities using seabed-mounted acoustic nodes during a UK-based subsurface demonstration. 2 sources. https://clstr.news/cluster/ecosub-robotics-and-sonardyne-demonstrate-autonomous-subsea-launch --- Cite as: Subsea robotics and sonar technology developments.
