COMBAT SYSTEMS SUBSYSTEMS

COMBAT SYSTEMS SUBSYSTEMS Because many subsystems comprise an overall combat systems, it would be impractical to cover all the subsystems within this chapter. We will, there- fore, discuss only a few of the major subsystems found aboard one ship class, the Oliver Hazard Perry (FFG-7). All subsystems are very important to the readiness of the overall combat systems. Therefore, as a senior technician and supervisor, you must work with your fellow combat systems technicians, super- visors, and operators to ensure a high state of combat systems readiness. COMBAT DIRECTION SUBSYSTEM The combat direction system (CDS) subsystem is a digital, computer-based, data-processing system that allows the crew to integrate, control, monitor, and make tactical use of the ship’s weapons systems. It also allows the use of task force weapons against air, surface, and subsurface threats. Sensor data from radar, sonar, countermeasures, and remote communications links are collected, correlated, and evaluated by the CDS operational program. The CDS program then develops and sends recommendations and alerts to the console operators to enable them to use their sensor and weapon resources efficiently. The CDS is composed of three major equipment groups: (1) data processing, (2) data display, and (3) data communications. COUNTERMEASURES SUBSYSTEM The countermeasures subsystem is a stand-alone subsystem that provides combat systems with detec- tion, surveillance, identification, and engagement capabilities against threats the ship encounters during a mission. This subsystem is divided into three functional groups: (1) electronic warfare support group, (2) acoustical countermeasures group, and (3) electronic attack group. Electronic Warfare Support Group The electronic warfare support (ES) group sup- ports actions taken to search for, intercept, locate, record, and analyze radiated electromagnetic energy in support of tactical operations. Thus, ES equipment provides a source of countermeasures information required for threat detection, warning, avoidance, and target acquisition. The ES group also receives triggers from ship- board emitters and develops the blanking pulses required to prevent the emitters from interfering with operating countermeasures equipment. The major components of the the Electronic Countermeasures (V)2; and (2) the Blanker-Video 10B. ES group are (1) Set, AN/SLQ-32 Mixer, AN/SLA- Acoustical Countermeasures Group The acoustical countermeasures (ACM) group provides deception devices designed to provide false or misleading acoustical targets for incoming acous- tical homing torpedoes. The major components of the ACM group are (1) the Torpedo Countermeasures Transmitting Set, AN/ SLQ-25 (NIXIE); and (2) the Prairie/Masker System. Electronic Attack Group The electronic attack (EA) group provides false or misleading targets for incoming missiles or other weapons. In conducting mission assignments, the ship uses decoy systems primarily as a defensive measure. The major component of Super Rapid Bloom Offboard 36 Mod 1. the EA group is the Chaff (SRBOC), Mk 4-4
