U.S.A. recently approved sale of anti-submarine warfare Sonobuoys to India estimated at $52.8 million.
About Sonobuoys:
- Anti-Submarine Warfare (ASW) Sonobuoys are specialized devices used in maritime military operations to detect, track, and engage submarines.
- They are a key component in anti-submarine warfare, allowing naval forces to locate and monitor the movements of enemy submarines.
- Sonobuoys are compact, buoyant devices that are deployed from aircraft, helicopters, or ships into the ocean.
- They are equipped with sensors to detect underwater sounds (acoustic signals) and transmit this data back to the deploying platform (aircraft, ship, etc.) via radio frequencies.
Types of Sonobuoys:
- Passive Sonobuoys: These sonobuoys listen to the sounds in the ocean, such as submarine engine noise or propeller sounds, without emitting any signals themselves.
- They are used to detect and identify submarines based on the acoustic signatures they produce.
- Active Sonobuoys: These emit sound pulses (pings) and listen for the echoes that bounce back from objects in the water, including submarines.
- They are used to determine the range, bearing, and speed of the target submarine.
Functionality:
- Sonobuoys are deployed in patterns to cover a large area of the ocean. The data they collect is used to triangulate the position of a submarine.
- The acoustic data gathered by the sonobuoys is transmitted via radio signals to the host platform, where it is analyzed by ASW operators.
- Some sonobuoys are designed to communicate with other sonobuoys, creating a network that enhances the accuracy of submarine detection.
- Sonobuoys are often deployed from aircraft such as maritime patrol aircraft (e.g., P-8 Poseidon) or helicopters. They are dropped into the ocean using special launch systems.
- Sonobuoys are used in a variety of maritime operations, including:
- Surveillance: Monitoring specific areas for submarine activity.
- Tracking: Following the movements of a detected submarine.
- Targeting: Providing precise location data for launching anti-submarine weapons like torpedoes.
