ASELBUOY Passive Directional Sonobuoy: Enhancing Underwater Surveillance Capabilities ASELSAN, a leading defense electronics company, introduces the ASELBUOY, a state-of-the-art passive directional sonobuoy designed to enhance underwater surveillance and security. The ASELBUOY is a NATO A-size device, capable of being deployed from both aircraft and surface ships, making it a versatile tool for maritime defense operations. General Features and Capabilities The ASELBUOY is equipped with a DIFAR (Directional Frequency and Ranging) sensor, which provides precise directional acoustic information in the 5 – 2400 Hz frequency band on the horizontal plane. This capability allows for accurate detection and localization of underwater threats, such as submarines and other vessels, crucial for maintaining maritime security. One of the standout features of the ASELBUOY is its programmability. Operators can configure the sonobuoy through a local user interface, tailoring its performance to meet specific mission requirements. With a 1W RF output power and access to 96 VHF channels (ranging from 136 MHz to 173.5 MHz), the ASELBUOY ensures reliable communication and data transmission, even in challenging environments. The ASELBUOY is also designed for flexibility, capable of operating at two different depths. This feature enhances its adaptability to various operational scenarios, providing valuable acoustic data across different layers of the ocean. Applications and Strategic Importance The ASELBUOY is primarily used for anti-submarine warfare (ASW), a critical component of modern naval operations. By deploying these sonobuoys, military forces can monitor vast oceanic areas, detecting and tracking submarines with high precision. This capability is vital for safeguarding naval assets, protecting maritime borders, and maintaining strategic superiority in contested waters. In addition to ASW, the ASELBUOY is also employed in search and rescue missions, environmental monitoring, and underwater research. Its ability to provide accurate acoustic data makes it an indispensable tool for a wide range of underwater applications. Commitment to Technological Excellence ASELSAN’s development of the ASELBUOY reflects its commitment to advancing maritime defense technologies. By leveraging cutting-edge technology and extensive expertise, ASELSAN continues to provide innovative solutions that meet the evolving needs of modern defense forces. The ASELBUOY is a testament to ASELSAN’s dedication to enhancing Türkiye’s defense capabilities, ensuring that its naval forces are equipped with the most advanced tools for maintaining security and stability in the maritime domain.
