AN/BQQ-5 bow-mounted spherical array
sonar acoustic system is deployed on SSN 637 and SSN
688 attack submarine classes. This low frequency passive
and active search and attack sonar is supplied by IBM.
The AN/BQQ-5E sonar with the TB-29 towed array and Combat
Control System (CCS) Mk 2, known collectively as the
QE-2 System, provides a functionally equivalent system
for the Los Angeles (SSN-688) and Ohio (SSBN-726)-class
submarines. Enhancements include increases in acoustic
performance, improved combat control capabilities and
replacement of obsolete equipment.
OPEVAL for AN/BQQ-5E system with the
TB-29 Array completed in FY 1998; this system will provide
quantum improvements in long-range detection and localization
for SSN 688 and SSBN 726 Class Submarines. Engineering
Change Proposal (ECP) 7001 to AN/BQQ-5E will provide
Low Frequency Active Interference Rejection, Dual Towed
Array Processing, and Full Spectrum Processing to SSN
688 and SSBN 726 Class Submarines.
The AN/BSY-1 ECP 1000, the AN/BQQ-5
Medium Frequency Active Improvement program and Improved
Control Display Console Obsolete Equipment Replacement
have been modified to become the basis of the Acoustics
Rapid Commercial Off The Shelf Insertion (A-RCI) program.
A-RCI is a multi-phased, evolutionary development effort
geared toward addressing Acoustic Superiority issues
through the rapid introduction of interim development
products applicable to SSN 688, 688I Flight, and SSBN
726 Class Submarines. A-RCI Phases I and II introduce
towed array processing improvements; A-RCI Phase III
introduces spherical array processing improvements.
The Trident Submarine System Improvement
Program develops and integrates command and control
improvements needed to maintain Trident submarine operational
capability through the life cycle of this vital strategic
asset. The program conducts efforts needed to ensure
platform invulnerability, and reduce life cycle costs.
Recent efforts have included the development of AN/BQQ-6
Sonar to AN/BQQ-5E Sonar Translator.
