SSG(X) Design – VT Team 3 Page 18 Table 11 - Components list for SONARSYS system The sonar system for a submarine provides the ears and brains for the vessel. The bow sonar dome is the most critical piece of sonar equipment. The bow sonar dome is mounted in the bow and is usually spherical. The outer portion is covered with transducers for listening. The BQQ-10 is the most current and effective dome used on USN submarines today, specifically the Virginia class. The dome provides low frequency passive and active search sonar capabilities. The BQQ-10 is an upgrade from the BQQ-5 which is on the Los Angeles class submarines. Utilizing COTS software has allowed the BQQ-10 to stay more current, keep costs down, and improve the acoustic performance. The BQQ-10 can be integrated with any of the control systems and works in conjunction with the flank side arrays and the towed arrays. Another significant element in the sonar suite includes the Light-Weight Wide Aperture Array (LWWAA) and the BQG-5 Wide Aperture Array (WAA) options, which are flank side arrays. Both options consist of large panels mounted along the side of the hull providing major sonar sensor input into the combat system. The LWWAA is a newer more advanced system than the BQG-5. Instead of traditional ceramic hydrophone sensors, LWWAA uses fiber-optic and laser technologies to convert acoustic energy into information that can be used to track and shoot. LWWAA also provides weight and cost savings of 54% and 37% respectively. The weight savings are attributed to the upgraded transducers. High frequency sail and chin arrays are also important components of the sonar system suite. They are located on the sail and bottom of the bow respectively. These systems are specifically designed for littoral warfare operations. The chin array is mainly used for mine and ice detection. Figure 10 illustrates where the different sonar suite systems are located. Figure 10 - Overall sonar system [navsource.org]
SSG(X) Design – VT Team 3 Page 19 The thick and thin towed arrays complete the sonar system suite. The towed array options for SSG(X) are TB- 29A and TB-16. Both are currently used on Virginia Class submarines. The TB-29A is the most advanced thin line array and works well in combination with the BQQ-10 and any combat system. The TB-16 is a proven thick line array on the modern USN submarines. Figure 11 shows various parts of a towed line array. Figure 11 - Towed line array [Dr. Brown, Ship Design Notes] The fourth option for SONARSYS is the sonar suite manufactured by Thales and found on foreign submarines. Thales is designed for multi-missions and long and short range ASW. The suite includes passive bow cylindrical arrays, planar flank arrays, intercept arrays, passive ranging arrays, and a self-noise monitoring system. The system is also capable of mine and obstacle avoidance. The use of COTS helps keep costs low and the system up-to-date. Thales claims improvements of weak signal resolution, an increase in S/N ratio, and improved detection at high speeds. The brain of a USN submarine is the combat system. The SSG(X) has three options for its “brains” or combat systems. The BSY 1 CCS MK 2, BSY-2 and CCSM are all proven and fully capable systems, shown in Figure 12. These systems control sonar, combat control, electronics, and major subsystems. The CCSM utilizes COTS as an upgrade from the BSY-2 system found on the Seawolf class of submarines. The BSY-2 is an improvement from BSY-1 and allows for integration of future missions and upgraded capacity. Figure 12 - BSY system [Dr. Brown, Ship Design Notes] Each SSG(X) option includes underwater communication, communication electronics and equipment, navigation echo sounders, ISR control and processing. These components work in cooperation with the CCSM, BSY, or Thales suite. [Jane’s Underwater Warfare Systems, 2005-2006] 3.1.4.2 SAIL Table 12 lists the components for each of the sail system alternatives. The sail contains the radar, visual, and communication equipment of the submarine. Each option includes two of either a photonics or traditional mast and radar equipment. Each option also includes the necessary snorkel equipment and an Unmanned Aerial Vehicle
