The first footage of the use by the Russian Black Sea Fleet of the Alexandrite-ISPUM-E underwater complex designed to search and destroy mines. The Alexandrite-ISPUM complex is located on a Project 12700 sea minesweeper of the Baltic Fleet. The Alexandrite-ISPUM complex was developed in 2015 by the scientific enterprise Region. The complex became the development of the first similar third-generation system, the Mayovka underwater mine detector-detector, which is now used in the Black Sea Fleet. The complex was first used in the Baltic, where it was used to find not only sunken ships, but also small items of sailors’ uniforms. The Alexandrite-ISPUM complex is capable of detecting an object under a three-meter layer of silt. The Alexandrite-ISPUM complex includes a hydroacoustic ship station, a towed hydroacoustic station and a self-propelled underwater vehicle. The system works as follows: a towed hydroacoustic station “scans” the aquatic and underwater environment. A self-propelled underwater vehicle searches for suspicious objects within a radius of 500 meters and at a depth of up to 300 meters; it can also be equipped with a bomb. After detecting dangerous objects and mines, explosive charges are installed on them or cable cutters are used. If necessary, the devices can tow a mine into shallow water and destroy it there. The fourth generation complex “Alexandrite-ISPUM-E” is now the most modern Russian system for searching and destroying sea mines. It is planned to equip all Russian sea minesweepers of Project 12700 with the Alexandrite-ISPUM-E complexes.
