Figure 4-2 is a pictorial diagram of how the search
radar subsystem interfaces with the combat direction
system subsystem.
COUNTERMEASURES SYSTEMS
The countermeasures subsystem, a stand-alone
subsystem, provides the combat system with detection,
surveillance, identification, and engagement
capabilities against threats the ship encounters during a
mission.
The countermeasures subsystem is divided into
three functional groups: the electronic support
measures (ESM) group, the acoustical countermeasures
group (ACM), and the electronic countermeasures
(ECM) group.
The ESM group supports actions taken to search for,
intercept, locate, record, and analyze radiated
electromagnetic energy in support of tactical operations.
Thus, ESM equipment provides a source of
countermeasures information required for threat
detection, warning, avoidance, and target acquisition.
The ESM group also receives triggers from shipboard
emitters, and develops the blanking pulses required to
prevent the emitters from interfering with operating
countermeasures equipment. The major components of
the ESM group are the Electronic Countermeasures Set
AN/SLQ-32(V)2 and the Blanker-Video Mixer
AN/SLA-10B.
The ACM group provides deception devices
designed to provide a false or misleading acoustical
target for incoming acoustical homing torpedoes. The
major components of the ACM group arc the Torpedo
Countermeasures Transmitting Set AN/SLQ-25
(NIXIE) and the PRAIRIE/MASKER SYSTEM.
The ECM group provides false or misleading targets
for incoming missiles or weapons. In conducting
mission assignments, the ship will use decoy systems
primarily as a defensive measure. The major component
of the ECM group is the Super Rapid Bloom Offboard
Chaff (SRBOC) Mk 36 Mod 1.
CLOSE-IN WEAPON SUBSYSTEM (CIWS)
The Close-In Weapon System (CIWS) Mk 15 Mod
1 provides the final defense against antiship cruise
missiles (ASCM) as part of the Navy’s defense-in-depth
concept. The CIWS will engage and destroy ASCMs or
aircraft that penetrate a ship’s primary defense envelope.
The CIWS also provides ASCM and antiair defense for
ships operating in other than defense-in-depth
situations. The CIWS is essentially a stand-alone
weapon system consisting of the Weapon Group Mk 16
Mod 1, Remote Control Panel (RCP) Mk 340 Mod 1,
and Local Control Panel (LCP) Mk 339 Mod 2. The
CIWS may be operated in either the antiair warfare
(AAW) automatic mode or the AAW manual mode.
UNDERWATER WEAPON SUBSYSTEM
The underwater weapon subsystem provides the
combat system with an engagement capability against
subsurface threats. The underwater weapon subsystem
is composed of the following equipment:
1.
2.
3.
4.
Sonar Set AN/SQS-56
Tactical Towed Array Sonar (TACTAS)
Torpedo Tubes Mk 32 Mod 5
Control Panel Mk 309 Mod 0
LIGHT AIRBORNE MULTIPURPOSE
SYSTEM (LAMPS)
The light airborne multipurpose system (LAMPS)
is a combined helicopter-ship subsystem capable of
supporting both combat and noncombat missions. The
primary combat missions are antisubmarine warfare
(ASW) and antiship surveillance and targeting (ASST).
The secondary, noncombat missions include search and
rescue, medical evacuation, vertical replenishment, and
utility operations.
The LAMPS consists primarily of an SH-60B
Seahawk helicopter. The LAMPS helicopter is an
all-weather, airborne platform capable of carrying
various detection devices, including a sonobuoy
receiver-transmitter for transferring sonobuoy data to
the ship. Shipboard LAMPS equipment consists of a
Telemetric Data Receiving Set AN/SKR-4A (SKR-4)
and a Sonar Signal Processing Set AN/SSQ-28.
MISSILE/GUN WEAPON SUBSYSTEM
The missile/gun weapon subsystem enables the
combat system to deliver to a target an SM-1 missile
warhead or a 76-mm gun projectile. This subsystem uses
internally and externally generated raw data and
processed data to provide the combat system with
weapon assignment, direction, and firing capability. The
missile/gun subsystem supports the combat system
antiair warfare (AAW), surface warfare (SUW), and
antisubmarine warfare (ASW) missions.
