Advanced Combat Direction System (ACDS)

Primary Purpose The Advanced Combat Direction System is a

centralized, automated command and control

system, collecting and correlating combat

information. It upgrades the Naval Tactical Data

System (NTDS) for aircraft carriers and WASP

class amphibious ships as well as adding the

capabilities to TARAWA class ships. A core

component of CV/CVN/LHD/LHA class combat systems,

ACDS provides the capability to identify and

classify targets, prioritize threats and initiate

engagements, vector interceptor aircraft to

targets, and exchange targeting information and

engagement orders within the battle group and

among different service components in the joint

theater of operations.

Sub-Functions ACDS is a central repository of all tactically

significant tracks for the battle group as well

as own ship. It consists of equipment, computer

programs, and personnel engaged in collecting,

correlating, displaying, and disseminating ship

and force track information, evaluating track

threat potential, assigning weapons, generating

and disseminating force orders, monitoring

individual and force engagements, and controlling

aircraft.

Equipment Requirements Data Processing Group: AN/UYK-43A (V) Computer

set (ACDS DSP/TMP) (Block 0/1); TAC-4 Computer

Set (DMP) (Block 1), RD-358 (V) 5/UYK or RD-358A

(V) UYK Digital Data Recorder/Reproducer;

AN/USQ-69 (V) Data Terminal Set: OJ-172 (V) I/O

Console and associated peripherals (Block 0/1),

Peripheral Emulation System (PES) (replaces

RD-358, AN/UYH-3, AN/USQ-69) (LHD 7) Multi LAU

Cabinets. Data Display Group: OJ-451 (V)

9/UYQ-21 Computer Display Console; OJ-535 (V)

2/UYQ-21 (V) Display Control Console (Block

0/1): UYQ-70 Display Console (Block 1), Shipboard

Display Emulator (LHAs); IP-1357 / UYQ-21 (V)

Digital Data Indicator; LS-653/654A/UYQ21 Console

Intercommunications Units, Large Screen Display

(LSD); and associated peripherals (Block 0/1).

Connectivity Requirements No requirement for monitoring own-ship

operations. Communications and data link (LINK

11/14/16) required for monitoring force

operations.

Crypto Requirements None

Normal Locations Installed in CV/CVN/LHD/LHA class ships, and

shore sites including SCSC Wallops Island, CDSA

Dam Neck, Raytheon Electronic Systems, Integrated

Combat System Test Facility San Diego, and Fleet

Combat Training Center-Atlantic.

Information Managed Tactical air, surface, subsurface and electronic

warfare environments.

Products Created Data analysis and data reduction for operational

programs and hardware configurations. The system

also creates a "picture" based upon software

analysis for display of Detect, Control, and Engage (DCE) functions on AN/UYQ-70, AN/UYQ-21 and Large Screen display devices.

Lead Service/Contractor U.S. Navy/CDSA Dam Neck (Block 0) and Raytheon

Electronic Services, San Diego, California (Block 1).

Current Fielding Status The ACDS upgrade is divided into two phases,

Block 0 and Block 1. The Block 0 interim system

replaces obsolete NTDS computers and display

devices with modern equipment and incorporates

both new and upgraded software. Block 1, has

completed development, and operates with the

equipment provided under ACDS Block 0 while

implementing significant improvements in software

performance and capabilities. The Block 1

upgrades include modifiable doctrine, Joint

Tactical Information Distribution System (JTIDS)

and Link-16 for joint and allied

interoperability, increased range and track

capacity, multi-source identification, National

Imagery and Mapping Agency (NIMA)-based maps.

The upgrades will ensure that ACDS will continue

to meet projected threats that may be

encountered. ACDS Block 0 is deployed in nine

aircraft carriers, seven Wasp (LHD-1), and five

Tarawa (LHA-1) class amphibious assault ships.

ACDS Block 1 is installed in three aircraft

carrier and two WASP Class amphibious assault

ships. ACDS Block 0 and Block 1 ships will

transition to SSDS MK 2 in accordance with the

Maritime Force Protection Plan.

Known Problems Although ACDS Block 1 OPEVAL in February 1998 was

unsuccessful and included discrepancies in HMI

and Reliability, Maintainability, and

Availability (RM&A) the program has since

incorporated reliability and maturity

improvements, completed Navy and Joint Link

certification, and is conducting concurrent, COTF

observed, testing in conjunction with CEC. No

new enhancements/capabilities will be added to

the ACDS Block 1 operational computer program as

transition to SSDS has begun.
