SSN Acoustic Equipment

The SSN Acoustic Equipment program is focused on enhancing the acoustic capabilities of various classes of submarines within the U.S. Navy. The primary goal is to maintain acoustic superiority over adversaries by upgrading and procuring advanced sonar systems and equipment. This includes the Acoustic Rapid COTS Insertion (A-RCI) program, a multi-phased effort aimed at improving detection, classification, and tracking capabilities through software and hardware updates. The program supports several submarine classes, including the SSN 688, 688I Flight, SSN21, SSGN, VIRGINIA Class, and OHIO Class submarines.

One of the key objectives is to modernize and sustain approximately 8-12 SSNs and 2-3 SSBNs annually through bi-annual software Advanced Processing Builds (APBs) and hardware Technical Insertions (TIs). This ensures that the submarines remain operationally effective and capable of countering emerging threats. Additionally, the procurement of towed systems such as TB-29C and TB-34A arrays aims to improve reliability, extend service life, and maintain inventory levels for fleet use.

The program also focuses on specific upgrades like the Low Cost Conformal Array (LCCA) for enhanced situational awareness in high-density environments and the High Frequency Sail Array (HFSA) for improved anti-submarine warfare capabilities. These upgrades are crucial for maintaining operational readiness in both peacetime engagements and potential conflict scenarios. The procurement strategy includes addressing obsolescence issues by integrating new technologies into existing platforms to ensure continued supportability.

The SSN Acoustic Equipment program is a comprehensive effort to equip U.S. Navy submarines with state-of-the-art acoustic technologies that enhance their stealth and detection capabilities. By investing in these upgrades, the Navy aims to ensure its submarines can operate effectively in diverse maritime environments while maintaining a strategic advantage over potential adversaries.
