MIL-DTL-24784-3 Combat System Technical Operations Manual \(Cstom\) Requirements \(See Notice 2 For Replacement Information\)This specification sets forth the Naval Sea Systems Command requirements for the content, general style, and format of Combat System Technical Operations Manuals \(CSTOM\) \(see 6.2\) required for maintaining own-ship combat system \(see 6.3.3\) readiness. CSTOM provides operational forces and school commands with combat system level information concerning design, detailed inter-subsystem interface data, testing, maintenance, and capabilities in fleet user-oriented language and format. The CSTOM documents functional integration of all combat subsystems \(see 6.3.2\) in performance of the major combat system operational functions of detection and entry, tracking and identification, threat evaluation and threat-to-weapon pairing, and engagement and engagement assessment.

MIL-DTL-24784/3B (SH)

Chapter 9 according to the accuracy and the conditions under which entries from one source are

more accurate than those from another. The limitations imposed on the subsystems when using

incomplete or unreliable data shall be discussed. Threat entries shall be described in terms of

software configuration when applicable; for example, automatic mode versus manual mode. The

accuracies of radar data, optical data, sonar data, ESM data, IFF data and tactical data system

data links shall be provided in a table similar to figure 3-43.

3.10.3.3 Tactical data subsystem tracking and correlation. This section shall address the

maximum number of tracks capable of being simultaneously processed by the tactical data system.

Operator problems shall be addressed relative to radar distribution failures and console failures

which require one operator to search sectors normally searched by two or more operators. The

maximum and minimum processing time needed to establish a firm track under the manual and

automatic modes of operation shall be described. The comparative effect of tracking accuracies

on engagements by the different weapon subsystems shall be addressed. The reduced tracking

and correlation capabilities resulting from tactical data subsystem equipment malfunctions and

software configurations shall be described. Primary topics shall include track capacity, manual

and automatic tracking and correlation rates, tracking accuracy, reduction of hardware and

software capabilities caused by equipment casualties, and effect of degraded environment on

tracking accuracy. A table similar to figure 3-44 shall specify tactical data subsystem track

capacities.

3.10.3.4 Weapon direction system entry and tracking. This section shall describe the same basic

subject matter as that specified in 3.10.3.3. Additionally, the effect of weapon direction system

casualties shall be discussed. Primary topics shall include maximum number of tracks, tracking

accuracy in clear environment and degraded environment, and capability reductions resulting from

equipment casualties.

3.10.3.5 Identification and classification. This section shall describe the merits of various

identification sources. These sources shall include IFF and SIF, intelligence reports, ESM

receivers, ordered maneuver responses, and operational orders. Typical time spans required for

identification and classification using each of the identifying means shall be tabulated. Primary

topics shall include automatic threat identification, manual threat identification, ESM threat

identification (when not a part of manual or automatic threat identification), and sonar threat

identification.

3.10.3.6 Summary of combat system threat processing capabilities and limitations.

This section shall summarize the combat system threat processing capabilities and limitations for

supporting AAW, ASW, SUW and shore missions. Each primary topic shall describe the impact

threat processing has on mission success.

3.10.3.7 Bibliography. This section shall provide a list of documents used in preparing this

chapter.
