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 Electronic Countermeasures

ES group are (1)

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.
