Mine countermeasure systems
The mine countermeasure systems are rather urgent today due to huge number and variety of sea mines accumulated throughout the world. The most complicated challenge here is the bottom mines clearing.
JSC Concern “Sea Underwater Weapon - Gidropribor” has developed and produced the in-fluence sweeps (IS) to be used successfully against bottom mines with proximity fuzes which response to the ship physical fields.
The Concern develops two types of IS:
- classical IS
- imitating sweeps (IMS)
The fundamental difference between IMS and classical IM is that IM reproduces limited number of the ship physical field classification criteria in a broad swath, while IMS reproduces well greater number of the classification criteria but in a narrower swath comparable with a bot-tom-mine danger area.
The classic ISs are used to sweep mines with known characteristics.
IMSs are used to sweep up-to-date influence mines which implement complex processing algorithms to classify received signals and select the targets to be destroyed.
IMS is the only system to counter modern bottom mines in the environment overpowering for search and kill facilities, i.e. in harsh hydrological or hydrophysic environments, with self-burial or cover-up mines, as well as with mines silted and washed into the ground in either nor-mal or artificial way.
Besides influence sweeps, the Concern has developed mechanical sweeps of different types - different-depth sweeps, bottom double sweeps, net sweeps towed by minesweepers, helicopters and air-cushion crafts.
Along with the towed systems, the Concern has developed a lot of self-propelled remote-controlled (via a cable) unmanned underwater vehicles (UUVs) to perform a range of defence and economic missions.
