MIL-DTL-24784/3B (SH)
operations performed by combat system personnel and equipment during all major combat
missions. Volume 2 shall provide coverage of total combat system operational sequences for
AAW, ASW, SUW, and shore operations. Volume 2 shall assume readiness condition I manning.
Information provided shall address what is done and not how it is done. The user shall be referred
to subsystem technical manuals for detailed step-by-step equipment operations. The operations
required of each subsystem of the combat system shall be presented in relation to their
contribution to the combat system functions of detection and entry, tracking and identification,
threat evaluation and threat-to-weapon pairing, and engagement and engagement assessment. An
operational mode network (OMN) similar to figure 3-12, will provide the user with an overview
of the combat system functional requirements. The OMN (see 6.3.10) shall reference combat
system operational sequence network (OSN) (see 6.3.11), similar to figure 3-13, for explanation
of the operational sequences required for each function identified on the OMN. The OMN and
each combat system OSN drawings shall be supported by a textual description.
3.8.1 Chapter 4 - Operational sequences. Chapter 4 shall consist of an OMN, combat system
OSN drawings, and supporting text describing the sequential functional operations of the combat
system in conduct of ship combat missions.
3.8.1.1 Purpose and use of the OMN and OSN. This section shall describe the purpose and use
of the drawings contained in Chapter 4 to depict combat system operational sequences. The
relationship of the OMN and the combat system OSN drawings to each other and to other
volumes of the CSTOM shall be explained. The OMN diagram shall define combat system
operating sequences. The OMN (see figure 3-12), an overall summary and reference diagram,
shall provide for entry into more detailed operational functions depicted on second-level OSN
drawings, similar to figure 3-13. The OMN and OSNs shall be developed on the basis of the
major combat system operational descriptions specified in 3.7.3. OMN drawings shall identify all
major operational functions. Entry into the second-level OSN diagrams shall be by figure
reference from the first-level OMN. Each OSN shall subsequently cover a specific operational
function. Where operational functions refer to an operator action, reference shall be made to the
appropriate subsystem manual or system operator manual. The OMN drawing shall be reverse-
side printed with an apron to permit opening the OMN to the left while viewing individual OSN
drawings to the right. Each OSN shall specify the initial setup conditions and configuration
requirements upon which the OSN is predicated.
3.8.1.2 Detection and entry. This section shall describe the combat system detection and entry
operational sequence for the initial response to any air, surface, or subsurface detection while
operating in readiness condition I (see 6.3.7). Narrative description in this section shall be
supported by the OMN, and OSNs for each combat system subsystem, as appropriate.
3.8.1.3 Tracking and identification. This section shall describe the tracking and identification
operational sequence and procedures for the initial response to any normally expected threat that
may occur when operating in readiness condition I. Narrative description in this section shall be
supported by the OMN, and OSNs for each combat system subsystem as appropriate.
3.8.1.4 Threat evaluation and threat-to-weapon pairing. This section shall describe the threat
