Windward and Vantor launch dark‑vessel monitoring

Windward and Vantor said Wednesday they are combining satellite imagery and vessel analytics to keep tracking ships that switch off or spoof their signals. (windward.ai) The companies said the product plugs Vantor’s Sentry monitoring system into Windward’s Maritime Artificial Intelligence platform and is aimed at defense, intelligence, and commercial users. Windward said the system is designed to maintain “continuous custody” of vessels at global scale. (vantor.com) A ship normally broadcasts its position through the Automatic Identification System, a radio beacon used for navigation and collision avoidance. Windward and Vantor said their system is built for cases where that beacon is turned off, manipulated, or contradicted by other data. (windward.ai) Vantor said its satellites can collect optical imagery at roughly 30-centimeter resolution, which is fine enough to distinguish vessel features from orbit. Windward said its software then matches those images with what it calls vessel “fingerprints,” including behavior, route history, and other signatures. (vantor.com) The pitch comes after a year in which sanctions enforcement and conflict monitoring pushed more attention onto so-called dark fleets. Windward said in a December 2025 post that the number of vessels in the dark fleet had grown to more than 1,900 by the end of the third quarter. (windward.ai) Windward also said in March 2026 that it detected a more than 200 percent increase in dark-vessel activity during the first night of fighting tied to the Iran conflict. That kind of surge is the sort of case these systems are built to catch when standard ship transponders become less reliable. (windward.ai) The companies said the new workflow pulls together Automatic Identification System data, radio-frequency detections, synthetic-aperture radar, electro-optical imagery, and behavioral analysis in one system. Vantor said that replaces the older model in which analysts had to move between separate tools for detection, identity checks, and pattern analysis. (vantor.com) Related research highlighted this week shows the same demand for persistence closer to shore. A paper from the Universidad Politécnica de Madrid and partners said tethered drones for ports and coastal areas can stay aloft for extended periods and extend visual range by using a power cable instead of a battery alone. (iptc.upm.es) That leaves two layers of the same surveillance problem: satellites for wide-area tracking offshore, and tethered drones for long-duration watching near ports and coastlines. Windward and Vantor said their part of that stack is now available through the integrated platform they announced on April 15, 2026. (prnewswire.com)
