One of the areas of vulnerability both for warships, support vessels, and for coastal infrastructure is associated with possible underwater sabotage. IN stories world fleet There are many cases when BoPl (combat swimmers), committing sabotage at naval facilities, could disable not only an individual ship, but in fact an entire naval base for a fairly long period. Underwater sabotage against objects of the Navy (Navy) can lead to enormous damage, and therefore the question of how to resist submarine sabotage forces and means stands apart.
One of the most advanced anti-sabotage defense systems today is the Russian development - GAS OPD "Anapa" and "Anapa-M" ("Anapa-ME"). This is a sonar station for detecting underwater saboteurs. Moreover, its functionality allows you to detect not only sabotage means of the enemy, but also manpower - combat swimmers who have received the task of causing certain damage to ships or the coastal infrastructure of the base.
GAS OPD "Anapa-M" is engaged in extensive monitoring of the underwater situation both in the immediate coastal zone and in the area where warships and other vessels are stationed in the roadstead.
The system is capable of detecting BoPlanes moving both with the use of special towing vehicles and with fins. Anapa-M (Anapa-ME) has the ability not only to detect suspicious underwater objects, but also to quickly classify them with automated tracking of targets.
Receiving the coordinates of the detected object, the GAS OPD transmits them to the weapons control system. In this case, we are talking about anti-sabotage grenade launchers.
BoPl detection range at depths of up to 60 m for Anapa-M (with an accuracy of at least 90%) - up to 300 m in the case of a swimmer on fins, up to 400 m - on a towing vehicle. In this case, the level of interference corresponds to an indicator of 0,01 Pa / Hz.
The review is circular (360 degrees).
Anapa-M has an advantage due to the presence of an automated target classification system, which is also capable of detecting a false target.
The root-mean-square error of measuring the current coordinates does not exceed 2 percent.
The Russian development "Anapa-M" allows tracking up to 4 targets simultaneously with a minimum detection range of 25 m.
The system provides continuous monitoring for 120 hours. It is put on alert in 3 minutes. Power consumption - 1 kW.
Experts classify GAS OPD "Anapa-M" as one of the best anti-sabotage monitoring tools. It is noted that the automated version of the operation of the GAS OPD "Anapa-M" can significantly increase the level of security of the facilities of the Navy. The ongoing monitoring of the underwater situation at depths of up to 60 m and at a distance of up to 400 m ensures the creation of a security zone, which is the implementation of a complex of highly effective anti-sabotage measures. The complex was highly appreciated by specialists in anti-sabotage activities.
As they joke about this on the net: if the Swedes had the Russian "Anapa-M", they would not have to invent fables about "Russian saboteurs and underwater vehicles in the bay of Stockholm."
