A Comprehensive Guide to Underwater Drone Deployment Since the 1950s

Underwater Drone

Underwater drones have been created and deployed since the 1950s.

underwater drone technology was developed by the American Navy. It was in the 1960s that the Navy started using underwater cameras and drones to retrieve lost equipment and explore wrecks.

Even an underwater drone was employed in 1985 to locate the Titanic’s wreck. As with all things drones, the 2000s have seen a lot of improvement and an increase in capability and reach. Modern drones are far more advanced than anything that came before them and innovation continues still.


In the 1950s, the first underwater drones were developed They may serve the Navy and academic institutions thanks to their design.

The funding comes from the budget for defense. Drones came under the jurisdiction of the Navy, like many other Cold War technology.

Technology continued to improve in the 1960s. Due to this, a lost nuclear weapon may potentially be found by an underwater drone. The recovery took place off the Spanish coast and was kept a secret for many years.

In the 1970s, commercial enterprises began making considerable use of them. Even the crew of a stricken submarine’s crew was saved by an underwater drone in the 1970s. For their efficiency and capacity to perform tasks that humans are incapable of, droves have grown in popularity.

The 1980s were the most well-known decade that saw the introduction of underwater drones.

The Titanic’s discovery by Robert Ballard prompted the creation of a brand-new ROV. The Navy assisted as they created this device. The most recent version made it possible to find the renowned Titanic and Bismarck wrecks. Drones started performing more substantial work in the 1990s.

Modern drone versions can now deactivate mines and do other tasks that previously required human divers. Additionally, deployment strategies and battery life were enhanced. Due to these advancements, drone use has expanded to include additional sectors of the economy.

Underwater drone technology witnessed a significant increase in the 2000s. The advancement of lithium-ion battery technology was the cause of this.

The ability to build drones improved along with this energy storage technique. In the past, releasing a drone required a large cable and a fully loaded research ship. They might be deployed off considerably smaller vessels starting in the 2000s.

Drone usage has increased ever since. Around the world, underwater drones are utilized in both commercial and military operations.


The modern equivalent of a crewless submarine is a drone. It’s difficult to communicate with these underwater drones They are capable of operating independently thanks to the integrated sensors. A lengthy cable that enables a direct link between the ship and the drone is a different approach.

  • To avoid sinking, an underwater drone controls its strength. They have crush depths and may be built for a variety of operating scenarios, like any underwater vehicle. The motors they employ enable the drone to move around either on its own or in response to commands.
  • The modern equivalent of a crewless submarine is a drone. Communication with these underwater drones is challenging. Because of the built-in sensors, they can function independently. A different strategy is to use a long cable that provides a direct connection between the ship and the drone.
  • An underwater drone controls its buoyancy to keep from sinking. Like any underwater vehicle, they may be constructed for a range of operating circumstances and have crush depths. The motors they use allow the drone to move in response to orders or out anonymously.

AUXILIARY Underwater Camera

With a specially mounted underwater auxiliary camera, you may add other perspectives to your video capabilities. This option, like the single auxiliary camera, attaches directly to the ROV. With the use of an auxiliary camera, pilots can see the grabber from a different angle or use a camera that faces backward to help guide the tether in perilous circumstances.


With underwater side-facing cameras, the ROV can capture even more perspectives. This option, like the single auxiliary camera, attaches directly to the ROV. For watching and recording, operators can switch between the main camera and the two side cameras using the toggle option. For a range of inspections, such as bridge, seawall, and fishnet inspections, side cameras offer useful alternative viewpoints.

Drones that can operate underwater are perfect for inspecting the outside of a ship’s hull.  Drones are frequently used in the oil and gas sector to inspect drill sites underwater.
After the BP oil disaster, during which daily drone footage was shown on network news, this became well known. Before it, they had been well-known for their success in searching for shipwrecks on the ocean below, including the Titanic and Bismarck.
The architecture of the vehicle determines how deep an underwater drone can operate. While some drones can dive to the ocean floor, others are made to do duties close to the surface. The pressure ratings and strong bracing used in the construction of these drones enable them to withstand the weight of the water.
Underwater drones don’t have to consider crew safety, in contrast to manned submersibles. Due to their ability to carry more sensors and instruments than a submersible of comparable size in the past, they can be considerably smaller. For researchers who utilize them for a variety of tasks, this is quite helpful.
underwater drones have revolutionized several fields, including the detection of possible ecological
crises and the discovery of new marine species. They can collect water and seabed samples from varied depths. These samples can be used by experts to assess pollution and possible risks to those who live close to the seaside.

Drones can operate in environments where people would find it difficult. These circumstances may involve protracted immersion in the Arctic’s frigid waters or harmful algae blooms. This makes it feasible for researchers and business interests to use sensors and technologies that were not even conceivable a few years ago.


Lightweight, Low Drag Tether: The Deep Trekker’s power supply is located inside the craft, which enables it to use a tether with a small diameter and little drag. The device uses all of the power from the neutrally buoyant tether (5mm–6mm depending on settings), NOT from pulling the bulky tether through the water. To manage the robots without the need for extra leads, high-strength fibers are included in the polyurethane tether.

Patented Pitching System: Deep Trekker underwater drones can travel in any direction by utilizing only horizontally placed thrusters thanks to their innovative internal pitching mechanism. The robot’s outer body may be oriented across a vertical arc using the pitching mechanism, which the pilot uses to steer the thrusters in the desired direction.

Fully Integrated Viewing & Control: With the help of our completely integrated super-bright-screen controller, bulky control boxes, difficult software, and additional power needs can be a thing of the past. The gaming-style controller comes with super-bright, sunlight-readable 5.6′′ screens for video and information overlay, making it by far the simplest and easiest method of piloting. It is also possible to install a second control box with complete PC functionality for SONAR, USBL, and sensors.

360-Degree Viewing: The 360-degree window, 270-degree camera sweep, and 180-degree pitch angle of the Deep Trekker underwater drones allow them to see in front, behind, above, and below, as well as any places in between. Each system includes an integrated LED lighting system that moves along with the camera.

Modular Add-Ons: Adaptability is crucial for growth and innovation at Deep Trekker. Our family of ROVs may be customized with a wide variety of accessories to meet a variety of requirements. One of the most crucial tools for ROVs to have is multibeam imaging sonar, which significantly enhances their capabilities in a variety of applications, including challenging and risky search and recovery operations and inspections in restricted places. These hard operations may be made simpler and safer to carry out In other circumstances, they might not even be feasible without the use of sonar.



Deep Trekker’s underwater drones are all quite durable. Each model is made of durable cast aluminum that has been anodized and epoxy coated to withstand corrosion. Our robots’ unrivaled longevity is a result of their distinctive spherical shape, which gives intrinsic strength without the need for maintenance thrusters. We provide a variety of attachments to improve the usefulness and longevity of your underwater drone if your project or application develops beyond the limitations of the device.


The development and advancement of underwater drone technology have mostly been driven by the Navy. An underwater drone is helpful for a wide range of economic interests, continuing a tradition carried on by the contemporary commercial sector.

They are often used by gas and oil firms to inspect regions that are already being drilled and to investigate areas that are being evaluated for drilling. underwater drones are used by foundations and organizations for oceanographic research to scan and study the seafloor.

They are also utilized by those having underwater infrastructure. Drones are employed to keep an eye on pipes that are submerged in the ground, which helps civilization get its oil and other necessities. These drones are strong enough to be used repeatedly.

Underwater drones are being used by the aquaculture sector to do net inspections, lighting, feeding, troubleshooting, and stock monitoring tasks more effectively. A cost-effective method for ensuring a healthy fish crop, a successful harvest, and environmental preservation is the deployment of underwater drones.

Divers’ safety is a primary consideration in commercial diving and inspections, and underwater drones enable them to do inspections in confined places, such as tanks, pipelines, and intake structures, without the hazards connected with the work.

As technology progresses, underwater drones are being created. Their use has increased as a result of their accessibility. They are diversifying into several ocean-related sectors.

We have identified two primary types of personas in Deep Trekker: hobbyists and professionals.

Underwater drones have grown in popularity as a pastime thanks to a rising interest in the ocean on the part of many people and the greater accessibility of once-expensive and non-commercially accessible technology. Whether you are a passionate photographer or videographer or simply curious about what lies beneath the sea, there is an underwater drone available for everyone. The entire solution for underwater observation for the enthusiast is provided by the ROV DTG3 Expert and ROV DTG3 Smart. The DTG3 ROV series delivers 4k video and camera capabilities straight to your handheld controller, with a depth rating of 150 meters, whether you’re wanting to explore historic shipwrecks or engage in recreational scuba diving.

ROVs can be used by a hobbyist for several tasks, including:

  • underwater exploration, which involves (studying marine life, coral reefs, and subaerial landforms)
  • Underwater Imaging and Filmmaking
  • Wreck Diving and Exploration.
  • Data recording (for environmental monitoring or inspections, for example)

The DTG3 Navigator ROV and its larger sister, the REVOLUTION ROV, are the best underwater drone for “the professional” and are utilized for ocean floor research or inspections at depths that divers are typically unable to reach. A working-class underwater drone, for instance, is widely used as a secure alternative for divers for offshore inspection projects, military and search & rescue missions, and in-depth archaeological inquiry. For instance, periodic hull inspections of a vessel are necessary throughout travel and while entering port to ensure structural integrity, prevent the possible transmission of invasive species, or detect contraband smuggling. Underwater drones from Deep Trekker reduce the danger associated with this activity.

ROVs may be utilized in commercial environments for several tasks. An expert could use ROVs for the following tasks:

  • Offshore Oil and Gas Industry (utilized for duties such as pipeline inspections, wellhead maintenance, and subsea equipment repairs).
  •  Inspections of hydroelectric power dams (which can help spot possible problems including fractures, silt accumulation, or structural deterioration)
  • Military & Defence (utilized by the US Navy for tasks such as the disposal of explosive ordnance, intelligence, surveillance, reconnaissance, salvage, and recovery);
  • Search and Recovery (used to assist police, fire, and first-aid teams in locating people who have vanished or who have drowned, as well as firearms, illegal substances, etc.).
  • Aquaculture (can assist with water quality testing, net inspections, feed monitoring, and fish monitoring).
  • Infrastructure (such as sewer and wastewater pipeline inspections, hydroelectric dam inspections, undersea cable inspections, etc.)
  • Scientific exploration and underwater archaeology (used to look at submerged archaeological sites, study submerged geology, conduct geological surveys, acquire vital information, take photos, and collect samples) Exploration of biological processes and archaeology (the recovery of artifacts from submerged sites and the mapping of underwater ecosystems).

Drones that operate underwater are far safer than divers. The drone’s pilot may sit in the security and convenience of a control room. By keeping a constant lookout for any possible threat, drone use can also boost the safety of following divers.

The underwater drone that can consistently complete all of these tasks is the best. Underwater drones of a commercial caliber are made by Deep Trekker. Their drones can carry out a range of tasks without endangering lives.

The amount of time underwater drones can stay is a significant benefit. Scuba tanks endure for an hour in shallow, choppy water. While some tank configurations might prolong this, the diver uses up more oxygen the more work they have to accomplish. Drones run on battery power and don’t require oxygen.
As a result, a project site may be continuously monitored.
underwater drone may also scale, depending on the demands of the work at hand. You don’t have to spend the money to buy an ROV (Remote Operated Vehicle) if one isn’t necessary and it’s not needed. There is no need for additional frills or add-ons because the DT Pod functions as an underwater drone camera.

Therefore, drones may handle mission-related problems without endangering human lives. Instead of needing a diver skilled in a variety of underwater profiles, you may scale your purchase to the work at hand.
Drone deployment does not necessitate high insurance and contractual fees. Some drones can be launched from any watercraft by a single person. They don’t require a large team or a crew to run, which lowers operational expenses significantly.


In the modern era, underwater drones have performed a variety of tasks, including rescue missions and maintenance. They have been the scene of both diplomatic disputes and underwater catastrophes. The inexpensive underwater drone, which has been around for about 70 years, is still helpful in many aspects of ocean operations.
Like all other drone-related technology, the underwater drone is here to stay. The world’s seas would be far less studied and accessible than they are now if not for underwater drone  
Even life on distant planets might be discovered by underwater drones. They continue to be among the most interesting and dynamic technical innovations ever used by humans. From the bottom of the ocean to space, drones are employed more than before.

Any endeavor requires the correct underwater drone, therefore choosing one is crucial. Please get in touch with Deep Trekker if you want to utilize an underwater drone Don’t take unnecessary risks with money and life; have faith in the technology that is transforming the world.
