Applicable Forms: Not Applicable; 35 hours

Use/relationship: This documents the Contract Work Breakdown Structure (CWBS) and its extension by the contractor using terminology and definitions, as applicable, in MIL-HDBK-881. The complete Program Work Breakdown Structure (PWBS) will serve as a basis for program and technical planning, scheduling, cost estimating, resource allocations, performance management where appropriate, configuration management, and status reporting.

This DID summarizes the format for the WBS and provides preparation instructions to support the specific data and frequency requirements specified in the contract. This DID is applicable to all contracts that require a WBS and is related to the two Contractor Cost Data Reporting (CCDR) formats: DD Form 1921, “Cost Data Summary Report” (DID number DI-FNCL-81565A), and DD Form 1921-1, “Functional Cost-Hour and Progress Curve Report” (DID number DI-FNCL-81566A). This DID can also be related to the formats contained in DD Forms 2734/1, 2734/2, 2734/3, 2734/4, and 2734/5, “Cost Performance Report” (DID number DI-MGMT-81466); DD Forms 2735, “Cost/Schedule Status Report, (DID number DI-MGMT-81467); and DD Form 1586, “Contract Funds Status Report” (DID number DI-MGMT-81468).

Routine reporting shall be at CWBS level 3 for prime contractors and key subcontractors.

MIL-HDBK-881 serves as the basis for identifying the first three levels of the PWBS and for developing the CWBS. Extensions of the PWBS and CWBS can be tailored to the specific program but will be consistent with MIL-HDBK-881. Detailed reporting of the CWBS (i.e., below level 3) shall be required only for those lower-level elements that address high-risk, high-value, or high-technical-interest areas of a program. Identifying these additional elements is a critical early assignment for the Cost Working Level Integrated Product Team (CWIPT) for inclusion in the PWBS.

The reporting contractor shall prepare and submit the contract dictionary within 60 days of contract award. The reporting contractor shall maintain and update the WBS Dictionary throughout the life of the contract. The dictionary shall not be submitted more frequently than report submissions.

The missile is a cylindrical body with four fixed fins attached to the aft end of the Solid Rocket Motor case. The control surfaces are located behind the fixed fins. The missile angular orientation is zero degrees at top center, with increasing angles positive in a clockwise direction (standing at the aft end looking forward). The outside surface of the missile body is coated for thermal protection of the structure from aerodynamic heating and rain erosion. Electrical interface between the launcher and the missile is provided by an umbilical cable connecting the missile Aft-Section to the Aft-Section of the Canister.

This element refers to the means for delivering the destructive effect to the target, including the capability to generate or receive intelligence to navigate and penetrate to the target area and to detonate the warhead. This element includes the design, development, and production of complete units (prototype and operationally configured units, which satisfy the requirement of their applicable specifications(s)) regardless of their use.

The propulsion system consists of the booster and the interstage. A single-stage, solid propellant rocket motor provides all of the boost impulse for the missile. The deployable flares and aft rate gyro package (RGP) are positioned at the aft end of the booster in the BUG configuration.

This element refers to the structural framework that provides the aerodynamic shape, mounting surfaces and environmental protection for the missile components. It includes the wings, fins, and structural body assemblies.

Warhead includes the assembly containing the kill mechanism of the round and its associated high explosives, chemicals, biological agents, nuclear devices, and pyrotechnics.

This element provides the roll rate control and the final velocity to adjust and deploy the payload as well as the external protection material, velocity control system, and deployment group.

This element refers to the missile’s ability to acquire and track targets, receive guidance data from various sensors and execute the necessary flight path to intercept the target.

This element refers to the missile’s ability to receive guidance data from various sensors.

The seeker assembly is attached to the kill vehicle via the forward ring of the forecone. The assembly consists of four elements; a seeker basecone, an IR sensor, a gimbal set, and a Seeker Electronics Assembly (SEA).

The seeker basecone is a conical assembly cast from magnesium. It is used as the main structure to mount the IR sensor and gimbals to the KV, and to dampen structural resonances.

This element includes all the electronic components and their structural items needed to perform all the seeker tracking functions.

This element includes all the electronic components and support structure needed to perform the electronic processing done outside, but near the detector assembly. This may include detector biasing electronics, preamplification, gain control processing, A/D conversion and multiplexing of the detector outputs when many detector outputs are present.

This element refers to the metal or composite materials that provide external housing, bulkheads, attach points and connectors for guidance and control equipment.

This element refers to the subsystem that starts the missile and maintains electrical power prior to launch, upon release from the launch platform, and during flight. Additionally, it consists of power supply devices and power converters.

The ordnance initiation set initiates all ordnance events throughout the missile and ground system (except reentry system components). Upon receipt of an electrical signal from the missile guidance and control system, the ordnance initiation set firing units convert the signal into ordnance outputs to the detonating cords. Among these ordnance events are stage separation, motor ignition, gas generator ignition, shroud separation, etc.

Includes through bulkhead initiators, ordnance test harnesses, and firing units/exploding bridge wires.

The airborne test equipment element refers to an exercise warhead that is interchangeable with the live warhead and suitable for developmental firing. This element includes destruct systems, recovery systems, special instrumentation, and telemetry equipment.

The airborne training equipment element refers to an exercise warhead that is interchangeable with the live warhead and suitable for training firing. This element includes destruct systems, recovery systems, special instrumentation, and telemetry equipment associated with the training mission.

The auxiliary equipment element refers to that additional equipment generally excluded from other specific elements. This element includes the environmental control, safety and protective subsystems, and destruct system. It also includes equipment of a single purpose and function that is necessary for accomplishing the assigned mission.

The IAT&CO of the hardware will be conducted at the contractor’s assembly facility. Subsystem components will be assembled and tested, then shipped to company YYYY for final assembly and testing.
