SeaDrones. Russian UUV Vityaz-D Descend to the Mariana Trench’s.

Intro

SeaDrones. The Russian unmanned submarine Vityaz-D has put its sturdiness to the test descending to the lowest point below sea level, the depths of the Mariana Trench, the country’s Vice Prime Minister Yuri Borisov revealed.

The submarine reached a depth of 10,028 meters on 8 May, spending over three hours studying the trench.

Mariana Trench’s lowest point is even more distant from sea level than the highest peak on Earth, Mount Everest.

Only a few expeditions have ever made it to the bottom of the trench due to the extreme water pressure at its lowest points, making it a real challenge for any piece of equipment.

The Mariana Trench is the deepest part of the seabed located near the Mariana Islands in the Pacific Ocean. It was first discovered in 1875.

But only a few expeditions have ever reached its lowest point due to the extreme levels of water pressure.

Only the sturdiest bathyscaphes and submarines are capable of reaching it for research purposes.

Immersion of the Vityaz submarine at the bottom of the Mariana Trench was carried out from the rescue tugboat Fotiy Krylov of the Pacific Fleet.

During the mission, mapping and video recording of the seabed were made, the parameters of the marine environment were studied.

In this dive, a pennant was installed at the bottom of the Mariana Trench, dedicated to the 75th anniversary of the victory of the USSR in the Great Patriotic War.

Vityaz Complex

Vityaz became the world’s first fully autonomous uninhabited underwater vehicle to reach the deepest point in the oceans. It is an integral part of the super-deep-sea diving complex.

The complex includes an autonomous uninhabited apparatus, a deep-sea bottom station and control room equipment.

Naval equipment of the complex provides information exchange of the carrier vessel with the underwater vehicle and the bottom station in real time via the sonar channel.

Sub device operates completely autonomously.

Thanks to the use of artificial intelligence elements in the control system of the device, it can independently bypass obstacles along the course, find a way out of a limited space and solve other intellectual problems.

Vityaz Components

 
Vityaz-D complex includes an autonomous uninhabited apparatus (ANPA SGP), a deep-sea bottom station (GDS SN), and control room equipment.

Naval equipment of the complex provides information exchange of the carrier vessel with the underwater vehicle and the bottom station in real time via the sonar channel.

ANPA SGP «Vityaz-D» is a permeable structure of zero buoyancy, power bases are made of titanium alloys. External contours are made of spheroplastic, which compensates for the excess weight of the device and gives it a streamlined shape.

The apparatus is driven by four marching and ten thrusters electric motors.

The Vityaz payload includes echo sounders, sonar navigation and communications equipment, side-scan sonars, video cameras, and other research equipment.

This equipment allows the apparatus to perform survey-search and bathymetric survey of the area, sampling to study the structure of the upper layer of bottom soil, sonar survey of the bottom topography, and measurements of hydrophysical parameters of the marine environment.

The device is capable of independently avoiding obstacles along the course, including leaving a limited space using elements of artificial intelligence in the control system.

Deep-sea bottom station in the process of fulfilling the mission acts as an underwater base station.

Device autonomously establishes communication with the GDS SN via a sonar channel and makes adjustments to its location.

Also, the deepwater station is capable of transmitting control commands from the carrier vessel to the AUV. The station body, as well as the body of the Vityaz-D apparatus, is made of titanium alloys and high-strength spheroplastic.

Unmanned Sub Warfare

China is hoping huge, new, smart unmanned submarines will help give its naval fleet an edge in crucial waterways like the South China Sea and the western Pacific.

Beijing expects to deploy artificially intelligent unmanned submarines in the early 2020s.

Subs could be used to survey waters, place munitions or even be used in suicide attacks against enemies, scientists involved in the program told the outlet. 

The Indian Navy has re-started a process to procure eight ‘high endurance’ autonomous underwater vehicles’ — mini unmanned submarines built for specific programmed tasks at sea.

Unmanned vehicles are envisaged to be used for anti-submarine warfare, mine-countermeasures and intelligence roles.

Indian Navy request the underwater drone should be capable of missions lasting a minimum of 15 days at an economical speed of 3 knots.

The official tender is expected to be released later this year and the procurement is envisaged to be completed by 2021.

Conclusion

One of the main advantages of the AI ​​subs, however, is their relatively low cost, as all of the investment that goes into making the vehicles survivable environments for humans can be stripped away.
 
Without those frills, the ships can operate fearlessly, using artificial intelligence systems to learn from what is happening around them without having to be concerned with protecting human cargo. 
 
Russia, EE.UU., China, and India are charting the way of naval warfare and its strategic rearrangement.
 
This path will soon be followed by the other nations with similar maritime interests.
