    OPERATING AND SUPPORT

    COST ELEMENT STRUCTURE DEFINITIONS

    The cost element structure for electronic systems encompasses defense materiel programs that employ electronics capabilities as their primary function. Examples include command and control systems, radar systems, communication systems, information systems, sensor systems, navigation/guidance systems, and electronic warfare systems. Some electronic systems are embedded in other primary defense systems; others are discretely identifiable as defense systems in their own right. When an electronic system is unique or is used as a building block for several systems but is not accounted for in those systems, it will be included in the electronic systems category.

1.0 MISSION PERSONNEL

    The mission personnel element includes the cost of pay and allowances for officer, enlisted, and civilian personnel required to operate, maintain, and support a discrete electronic system. This includes the personnel necessary to meet combat readiness, unit training, and administrative requirements. For personnel who operate, maintain, or support more than one type of defense system, personnel requirements will be allocated on a relative workload basis. Personnel costs will be based on manning levels and skill categories.

Note: Pay and allowances for officer and enlisted personnel should be based on the standard composite rate, which includes the following elements: basic pay, retired pay accrual, incentive pay, special pay, basic allowance for quarters, variable housing allowance, basic allowance for subsistence, hazardous duty pay, reenlistment bonuses, clothing allowances, overseas station allowances, uniform allowances, family separation allowances, separation payments, and social security contributions.
Pay and allowances for civilian personnel should be based on the standard composite rate, which includes the following elements: basic pay, additional variable payments for overtime, holiday pay, night differentials, cost-of-living allowances, and the government contribution to employee benefits, insurance, retirement, and the Federal Insurance Contribution Act.

1.1 OPERATIONS. The pay and allowances of the crew or full complement of personnel required to operate an electronic system. System operators may include officers, enlisted, or civilian personnel, or a combination of all three. In some cases, the equipment may be operated without a crew in an unattended mode.

1.2 MAINTENANCE. The pay and allowances of military and civilian personnel who support or perform maintenance on an electronic system, associated support equipment, and unit-level training devices. Depending on the system and the maintenance concept and organizational structure, this element will include maintenance personnel at the organizational level and possibly the intermediate level. Organizational maintenance personnel normally perform on-equipment maintenance; intermediate maintenance personnel perform off-equipment maintenance. If intermediate-level maintenance is provided by a separate support organization (e.g., a centralized intermediate maintenance support activity), the costs should be reported in element 3.0, Intermediate Maintenance (External to Unit).

1.3 OTHER MISSION PERSONNEL. The pay and allowances of military and civilian personnel who perform unit staff, security, and other mission support activities. The number and type of personnel will vary depending on the requirements of the particular system. These billets exist only to support the system whose costs are being estimated. Some examples are:

Note: The operation and maintenance of electronic systems at remote sites may in some cases require air (fixed wing/helicopter) support. The associated air support personnel and operating and support costs should be reported in element 6.0, Sustaining Support.

2.0 UNIT-LEVEL CONSUMPTION

    Unit-level consumption includes the cost of fuel and energy resources; operations, maintenance, and support materials consumed at the unit level; stock fund reimbursements for depot-level reparables; transportation in support of system operation and maintenance; temporary additional duty/temporary duty (TAD/TDY) pay; and other unit-level consumption costs, such as purchased services for equipment lease and service contracts.

2.1 ENERGY CONSUMPTION. Represents the unit-level cost of power required for the operation of an electronic system. May include battery, field-generated electricity, and commercial electricity necessary to support the operation of the system.

2.2 CONSUMABLE MATERIAL/REPAIR PARTS. The costs of material consumed in the operation, maintenance, and support of an electronic system and associated support equipment. Depending on the maintenance concept or organizational structure, consumption at the intermediate level should be reported either in this element or in element 3.0, Intermediate Maintenance (External to Unit). Costs need not be identified at the level of detail shown below; the descriptions are intended merely to illustrate the various categories of materials encompassed in this element.

2.3 DEPOT-LEVEL REPARABLES. The unit-level cost of reimbursing the stock fund for purchases of depot-level reparable (DLR) spares (also referred to as exchangeables) used to replace initial stocks. DLRs may include repairable individual parts, assemblies, or subassemblies that are required on a recurring basis for the repair of major end items of equipment.

Note: Defense Management Report Decisions (DMRDs) 901 and 904 of November 1989 proposed the establishment of a Defense Business Operations Fund (DBOF) under which DLRs would be consolidated under stock fund management. The cost of DLRs, previously a free issue to the consumer, must now be funded and budgeted by the resource user. A surcharge is added to the price of DBOF items to recover the cost of stock fund operations.

2.4 OTHER. Include in this element any significant unit-level consumption costs not otherwise accounted for. The costs identified must be related to the system whose operating and support requirements are being assessed. Examples might include:

3.0 INTERMEDIATE MAINTENANCE (EXTERNAL TO UNIT)

    Intermediate maintenance performed external to the unit includes the cost of labor and material and other costs expended by designated activities/units (third and fourth echelon) in support of an electronic system and associated support equipment. Intermediate maintenance activities include calibration, repair, and replacement of parts, components, or assemblies, and technical assistance.

3.1 MAINTENANCE. The pay and allowances of military and civilian personnel who perform intermediate maintenance on an electronic system, associated support equipment, and unit-level training devices.

3.2 CONSUMABLE MATERIAL/REPAIR PARTS. The costs of repair parts, assemblies, subassemblies, and material consumed in the maintenance and repair of an electronic system, associated support equipment, and unit-level training devices.

3.3 OTHER. Include in this element any significant intermediate maintenance costs not otherwise accounted for. For example, this could include the cost of transporting subsystems or major end items to a base or depot facility.

4.0 DEPOT MAINTENANCE

    Depot maintenance includes the cost of labor, material, and overhead incurred in performing major overhauls or maintenance on an electronic system, its components, and associated support equipment at centralized repair depots, contractor repair facilities, or on site by depot teams. Some depot maintenance actions occur at intervals ranging from several months to several years. As a result, the most useful method of portraying these costs is on an annual basis (e.g., cost per electronic system per year) or an operating-hour basis.

Note: The cost of depot-level reparables (DLRs) or exchangeables acquired through DBOF should be reported in element 2.0, Unit-Level Consumption.

4.1 OVERHAUL/REWORK. The labor, material, and overhead cost of regularly scheduled overhaul/rework of an electronic system and associated support equipment. The system may be returned to a centralized depot facility for maintenance, or depot field teams may do the work at the installation (e.g., satellite or radar station). Costs for major subsystems that have different overhaul cycles should be identified separately within this element.

4.2 OTHER. Include in this element any significant depot maintenance activities not otherwise accounted for. For example, this could include component repair costs for reparables not managed by the DBOF, second-destination transportation costs for weapon systems or subsystems requiring major overhaul or rework, or contracted unit-level support.

Note: Not all reparable items are acquired through DBOF. Centrally funded accounts may continue to finance items such as classified program DLRs, conventional and nuclear munitions items, and certain cryptologic electronics and telecommunication items.

5.0 CONTRACTOR SUPPORT

    Contractor support includes the cost of contractor labor, materials, and overhead incurred in providing all or part of the logistics support required by an electronic system, subsystem, or associated support equipment. Contract maintenance is performed by commercial organizations using contractor personnel, material, equipment, and facilities or government-furnished material, equipment, and facilities. Contractor support may be dedicated to one or multiple levels of maintenance and may take the form of interim contractor support (ICS) if the services are provided temporarily or contractor logistics support (CLS), where the support extends over the operational life of the system. Other contractor support may be purchased for engineering and technical services.

5.1 INTERIM CONTRACTOR SUPPORT. Interim contractor support (ICS) includes the burdened cost of contract labor, material, and assets used in providing temporary logistics support to an electronic system, subsystem, and associated support equipment. The purpose of ICS is to provide total or partial logistics support until a government maintenance capability is developed.

5.2 CONTRACTOR LOGISTICS SUPPORT. Contractor logistics support (CLS) includes the burdened cost of contract labor, material, and assets used in providing support to an electronic system, subsystem, and associated support equipment. CLS funding covers depot maintenance and, as negotiated with the operating command, necessary organizational and intermediate maintenance activities. If CLS is selected as the primary means of support, all functional areas included in the CLS cost should be identified in the cost element documentation.

5.3 OTHER. Include in this element any contractor support costs not otherwise accounted for. For example, if significant, the burdened cost of contract labor for contractor engineering and technical services should be separately identified and included here.

Note: Contractor support during the pre-operational phase of a system is typically funded as a system development or investment cost. However, post-operational contractor support is an O&S cost and should be addressed in this element.
After the ICS period, the government assumes responsibility for supporting an electronic system. However, contractor support may still be employed in specific functional areas, such as sustaining engineering, software maintenance, simulator operations, and selected depot maintenance. Applicable contractor costs should be reported against these elements in the CES. To avoid double counting, the contractor support element should be annotated to identify any contractor costs that are reported in other elements.

6.0 SUSTAINING SUPPORT

    Sustaining support includes the cost of replacement support equipment, modification kits, sustaining engineering, software maintenance support, simulator operations, and possibly air support for an electronic system. War readiness materiel is specifically excluded.

6.1 SUPPORT EQUIPMENT REPLACEMENT. The cost of replacing equipment that is needed to operate or support an electronic system, subsystems, training systems, and other support equipment. The support equipment being replaced (e.g., tools and test sets) may be unique to the system or it may be common to a number of systems, in which case the costs must be allocated among the respective systems.

Note: This element addresses replacement equipment only. The costs of initial support equipment are specifically excluded.

6.2 MODIFICATION KIT PROCUREMENT/INSTALLATION. The cost of procuring and installing modification kits and modification kit initial spares (after production and deployment) required for an electronic system and associated support and training equipment. Includes only those modification kits needed to achieve acceptable safety levels, overcome mission capability deficiencies, improve reliability, or reduce maintenance costs. Excludes modifications undertaken to provide additional operational capability not called for in the original design or performance specifications.

6.3 OTHER RECURRING INVESTMENT. Include in this element any significant recurring investment not otherwise accounted for.

6.4 SUSTAINING ENGINEERING SUPPORT. The labor, material, and overhead costs incurred in providing continued systems engineering and program management oversight to determine the integrity of a system, to maintain operational reliability, to approve design changes, and to ensure system conformance with established specifications and standards. Specific costs in this category may include (but are not limited to) government and/or contract engineering services, technical advice and training for component or system installation, operation, maintenance, and support.

6.5 SOFTWARE MAINTENANCE SUPPORT. The labor, material, and overhead costs incurred after deployment by depot-level maintenance activities, government software centers, laboratories, or contractors for supporting the update, maintenance and modification, integration, and configuration management of software. Includes operational, maintenance, and diagnostic software programs for the primary system, support equipment, and training equipment. The respective costs of operating and maintaining the associated computer and peripheral equipment in the software maintenance activity should also be included. Not included are the costs of major redesigns, new development of large interfacing software, and modifications that change functionality.

6.6 SIMULATOR OPERATIONS. The costs incurred to provide, operate, and maintain on-site or centralized simulator training devices for a weapon system, subsystem, or related equipment. This may include the labor, material, and overhead costs of simulator operations by military and/or civilian personnel, or by private contractors.

Note: On-site simulator operations and maintenance that are an integral part of unit manning and unit consumption should be reported as unit-level mission costs for the system in question. However, the costs of all contract-funded simulator operations and all centralized government simulator operations should be reported in this element.

6.7 AIR SUPPORT. Use this element to report the costs of any fixed-wing or helicopter support required at a remote electronic system site. Air support includes the operating and support costs of helicopter or fixed-wing aircraft that provide air surveillance, routine transportation, or emergency transportation between the host base, maintenance control facility, and remote site. Fixed-wing or helicopter operating and support costs include those contained in the aircraft CES.

6.8 OTHER. Include in this element any significant sustaining support costs not otherwise accounted for. Examples might include the costs of follow-on operational tests and evaluation, such as test support, data reduction, and test reporting.

7.0 INDIRECT SUPPORT

    Indirect support includes the costs of personnel support for specialty training, permanent changes of station, and medical care. Indirect support also includes the costs of relevant host installation services, such as base operating support and real property maintenance.

7.1 PERSONNEL SUPPORT. Personnel support includes the cost of system-specific and related specialty training for military personnel who are replacing individuals lost through attrition. Also included in this element are permanent change of station costs, and the cost of medical care. Each of these elements should be addressed separately. Descriptions are provided below:

Note: The cost of initial course development and training of Service instructors at contractor facilities is normally categorized as a system investment cost. However, the follow-on training costs of military and civilian personnel attending factory schools, as well as the cost of attending Service-conducted school-house specialty training, are O&S costs and should be reported in this element.
Normally, the costs of acquisition for recruiting, accession, and basic military training will not be included. However, if a significant change in Service recruiting and training objectives is required in order to support the system being assessed, then these costs should be addressed.

7.2 INSTALLATION SUPPORT. Consists of personnel normally assigned to the host installation who are required for the unit to perform its mission in peacetime. Include only those personnel and costs that are directly affected by a change in the number of systems and associated mission personnel. Functions performed by installation support personnel include:
