Autonomous underwater vehicles are untethered, self‑guided robotic submarines that carry sensors or tools to map the seafloor, inspect infrastructure, gather environmental data, or perform searches without a human on board. Think of them as flying drones for the ocean: they reduce labor, lower operational risk, and can work in places or depths people cannot reach. Investors watch them because demand links to offshore energy, seabed mining, undersea cables, defense and environmental monitoring, creating hardware, software and service revenue opportunities.
passive acoustic towed arraytechnical
A passive acoustic towed array is a long line of underwater microphones trailed behind a ship or submarine that listens for sounds in the water rather than sending out signals. Think of it as a long, quiet microphone dragged behind a boat to pick up distant engine noise or other underwater sounds. Investors care because contracts, upgrades, or exports of these systems affect defense and marine-equipment companies’ revenues, margins, and long-term service needs.
acoustic communicationstechnical
Acoustic communications uses sound waves to carry data instead of radio signals or wires, enabling devices to “talk” where radio won’t work well — for example underwater, inside metal structures, or in tiny implanted gadgets. For investors, it matters because it can create or expand niche markets (subsea sensors, industrial monitoring, medical devices), reduce installation complexity and costs, and become a competitive advantage for companies that commercialize reliable, low-power connectivity — like using a shout-and-listen system when other channels are blocked.
Passive Acoustic Monitoringtechnical
Passive acoustic monitoring uses unattended microphones or underwater microphones to record and analyze natural or human-made sounds—such as animal calls, ship noise, or machinery—without sending out any signals. For investors it matters because these sound surveys help companies meet environmental rules, detect operational issues, and limit legal or reputational risk, much like security cameras help a business spot problems early and avoid costly fines or delays.
hydrophone arraytechnical
A hydrophone array is a cluster of underwater microphones arranged to record and pinpoint sounds beneath the water’s surface, like a camera made of ears that can tell where and how loud noises are. For investors, its presence or quality signals a company’s ability to gather reliable underwater data—important for things like exploration, environmental monitoring, leak detection or defence contracts—so it can affect project success, regulatory compliance, ongoing costs and future revenue opportunities.
artificial intelligencetechnical
Artificial intelligence is the ability of computers and machines to perform tasks that typically require human thinking, such as understanding language, recognizing patterns, or making decisions. For investors, it matters because AI can enhance efficiency, uncover new insights, and enable smarter strategies, potentially impacting the value and performance of companies that develop or utilize this technology.
machine learningtechnical
Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.
Remote Operations Centertechnical
A remote operations center is a centralized hub that monitors and controls a company’s assets, systems or sites from a distance—like an air-traffic control room for machines, networks or facilities. It matters to investors because a well-run center can lower operating costs, improve uptime and safety, speed problem response, and reduce risk from outages or security breaches, all of which can protect revenue and support predictable growth.

THOUSAND OAKS, Calif.--(BUSINESS WIRE)--
Teledyne Technologies Incorporated (NYSE:TDY) today announced that, from January 17 through January 22, it conducted an Anti-Submarine Warfare (ASW) demonstration in Icelandic waters using its state-of-the-art autonomous underwater vehicles:
Slocum Sentinel Glider with a 60-meter-long passive acoustic towed array
Slocum G3 Glider with integrated Teledyne Benthos acoustic communications
Two Advanced Profiling Explorer (APEX) 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. “We are pleased to be demonstrating this technology which helps address a critical issue for global security,” said George Bobb, President and Chief Executive Officer of Teledyne. “We are excited to show what is possible with proven, mature, commercial technology currently in use by NATO militaries.”
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 – 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. “This result showcases our ability to meet a large percentage of existing requirements for conducting ASW with autonomous systems in the North Atlantic,” said Dan Shropshire, Vice President of Business Development for Teledyne Marine Vehicles and project lead. “The combination of our platforms with advanced sensor technologies, including the use of artificial intelligence and machine learning, allows us to bring a force multiplier to militaries world-wide, but at a fraction of the operational expense.”
In addition to the technical demonstration, Teledyne highlighted the ability to establish a Remote Operations Center with help from its long-time partner at the National Oceanographic Centre (NOC) in the United Kingdom, where Teledyne has a European Glider service and repair center. 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. “Teledyne already has a large footprint in the U.K. with 18 principal facilities and approximately 2,600 employees,” said Brian Maguire, Teledyne Marine Chief Operating Officer. “We are investing even more significantly to bring autonomous technology to the Ministry of Defense and the Royal Navy.”
