Valla bisey anlamadim, onlarla tartistimi ne?
ben para hibe ederim, Ukroturk de hazir
Qardashim bu bence az once paylashdigimiz video hakkinda sadece gec yazilmish bir haber. Bizim bir asker olduyu icin, bizimkiler de onlarin serheddeki mevkilerini bombaladi..

Wiki, overview
Current technologies
There are a large number of technologies used in modern anti-submarine warfare:
Sensors
- Acoustics particularly in active and passive sonar, sonobuoys, and fixed hydrophones aid in the detection of radiated noise. Sonar can be mounted on the hull or in a towed array.
- Pyrotechnics in the use of markers, flares and explosive devices
- Searchlights
- Radar, for surfaced parts
- Hydrodynamic pressure wave (wake) detection
- Laser detection and ranging of surfaced vessels; airborne and satellite
- Electronic countermeasures and acoustic countermeasures such as noise and bubble makers
- Passive acoustic countermeasures such as concealment and design of sound-absorbing materials to coat reflecting underwater surfaces
- Magnetic anomaly detection (MAD)
- Active and (more commonly) passive infra-red detection of surfaced parts.
An MH-60R conducts an airborne low frequency sonar (ALFS) operation during testing and evaluation.
In modern times forward looking infrared (FLIR) detectors have been used to track the large plumes of heat that fast nuclear-powered submarines leave while rising to the surface. FLIR devices are also used to see periscopes or snorkels at night whenever a submariner might be incautious enough to probe the surface.
The active sonar used in such operations is often of "mid-frequency", approximately 3.5 kHz. Because of the quietening of submarines, resulting in shorter passive detection ranges, there has been interest in low frequency active for ocean surveillance. However, there have been protests about the use of medium and low frequency high-powered active sonar because of its effects on whales. Others argue the high power level of some LFA (Low Frequency Active) sonars is actually detrimental to sonar performance in that such sonars are reverberation limited.
Weapons
Platforms[edit]
- Mines,
- Torpedoes, acoustic, wire-guided, and wake homing.
- Depth charges
- Rockets
- Missiles
- Anti-submarine net
- Ramming
Satellites have been used to image the sea surface using optical and radar techniques, and it is claimed[by whom?] these might be used for indirect detection of submarines, as could thermal imaging.[citation needed] Fixed-wing aircraft, such as the P-3 Orion & Tu-142 provide both a sensor and weapons platform similar to some helicopters like the SH-60 Seahawk, with sonobuoys and/or dipping sonars as well as aerial torpedoes. In other cases the helicopter has been used solely for sensing and rocket delivered torpedoes used as the weapon. Surface ships continue to be a main ASW platform because of their endurance, now having towed array sonars. Submarines are the main ASW platform because of their ability to change depth and their quietness, which aids detection.
In the future unmanned vehicles may be used in the ASW role. In early 2010 DARPA began funding the ACTUV programme to develop a semi-autonomous oceangoing unmanned naval vessel.
Today some nations have seabed listening devices capable of tracking submarines. It is known to be possible to detect man-made marine noises across the southern Indian Ocean from South Africa to New Zealand.[citation needed] Some of the SOSUS arrays have been turned over to civilian use and are now used for marine research.
