The AN/BSY-1 High Frequency Upgrade is a stand-alone program which will be introduced as A-RCI Phase IV for SSN 688I only. Towed systems development efforts will focus on tow cable improvements for shallow water towing in littoral environments; hydrophone and telemetry cost and risk reduction initiatives; (c) mechanical endurance improvements; sonar standardization; (e) OA-9070 handling system reliability enhancements; and TB-29 () towed array development.
There are three versions of Combat Control System [CCS]: CCS Mk 1, BSY-1, and CCS Mk 2. The latest upgrade to CCS Mk 1 and BSY-1 is Program C4.2V2A, which provides Sturgeon (SSN-637)- and Los Angeles (SSN-688 and 688I)-class submarines with an upgraded shallow water variant of the Mk 48 ADCAP torpedo. Additional capabilities are Tomahawk Block III, an interface to Acoustics Rapid COTS (A-RCI) upgrades, and an interface to the Global Command and Control System- Maritime (GCCS-M), formerly called the Joint Maritime Command Information System (JMCIS).
CCS Mk 2 Block 1 is a phased development program that provides significant warfighting improvements to SSN-688, SSN-688I, and SSBN-726 class submarines. The first phase, Block 1A/B, provided shallow-water ADCAP torpedo capability as well as interfaces to GCCS-M and the Advanced Tomahawk Weapon Control System (ATWCS). Both GCCS-M and ATWCS are Government Off-The-Shelf products developed by other Navy program offices (see separate program summaries). CCS MK2 Block 1C, planned for fleet introduction at the end of FY 1999, forms the basis of a common Integrated Development Plan (IDP) between SSN-688, SSN-688I, and the Virginia (SSN-774) classes of submarines. This common IDP will ultimately incorporate common Tactical Tomahawk, Improved Submarine-Launched Mobile Mine (ISLMM), and improved ADCAP capabilities across all submarine platforms, as well as updates to GCCS-M and ATWCS.
Program C4.2V2A installations have begun and are expected to complete in FY 1999 for all CCS Mk 1 and AN/BSY-1 systems. CCS Mk 2 Block 1A/B successfully completed two dockside installations and Operational Evaluation in the third quarter of FY 1997. The next upgrade to CCS Mk 1, BSY-1, and CCS Mk 2 Block 1A/B will be CCS MK 2 Block 1C. CCS Mk 2 Block 1C Milestone II was completed in the third quarter FY 1996. Planned installations to support development and operational testing are on schedule for FY 2000.
