Teledyne Technologies Incorporated — from January 17 through January 22 — conducted an Anti-Submarine Warfare (ASW) demonstration in Icelandic waters using its series of autonomous underwater vehicles, including: Slocum Sentinel Glider with a 60-meter-long passive acoustic towed array; Slocum G3 Glider with integrated Teledyne Benthos acoustic communications; and Two Advanced Profiling Explorer floats fitted with ambient noise Passive Acoustic Monitoring.

Several NATO members were in attendance to witness the trials which were conducted from the Teledyne Gavia facility located in Kópavogur, Iceland.

With assistance from the Icelandic Coast Guard, the Teledyne team was able to deploy the autonomous underwater gliders into the North Atlantic in the strategic Greenland-to-Iceland gap from the Coast Guard Ship ICGV Þór. The Sentinel Glider towed a passive acoustic thin-line hydrophone array specifically designed to identify surface and subsurface vehicle noise in the water. The silent autonomous gliders, transversing the water column to 1,000 meters and equipped with the sensitive passive acoustic array, create a formidable barrier for subsea adversaries.

In addition to acoustic payloads, Teledyne demonstrated the ability for its glider to acoustically exfiltrate data from a sea-bottom node, deployed as part of the demonstration. Simulated mission data was recovered from the node in real-time and later transmitted via satellite to the shore-based Mission Operations Control Centers in Iceland and the United Kingdom.

In addition to the technical demonstration, Teledyne highlighted the ability to establish a Remote Operations Center with help from the National Oceanographic Center (NOC). The gliders were piloted in tandem with Iceland from the NOC. Data was retrieved and displayed from the subsea node for use simultaneously at both Operations Center locations.
