DI-ENVR-80266A, DATA ITEM DESCRIPTION (DID): NUCLEAR HARDNESS AND SURVIVABILITY (NH&S) DESIGN ANALYSIS REPORT (09-DEC-2016)

DI-ENVR-80266A, DATA ITEM DESCRIPTION (DID): NUCLEAR HARDNESS AND SURVIVABILITY (NH&S) DESIGN ANALYSIS REPORT (09-DEC-2016).,This Data Item Description (DID) contains the format, content, and outline of the schedule of delivery requirements for the NH&S Design Analysis Report (DAR) which is produced as a result of tasking in 5.3.3.1.1, 5.3.4.1.3, and 5.3.4.1.4 of MIL-STD-1766C. This DID is applicable to system development/modification contracts for operational intercontinental ballistic missile (ICBM) hardware for which the contractor is required to conduct an NH&S program. It can also be used for any effort on ICBM hardware that makes changes to the design, thus creating a need for an updated NH&S DAR (change pages), such as during sustainment activities of MIL-STD-1766C, section 5.5. This report documents the methodology and results of the contractor’s activity to incorporate specified nuclear hardness and survivability (NH&S) requirements into the design of each configuration item (CI) and its elements. This report is used (1) by the procuring agency to evaluate the degree to which the contractor has clearly demonstrated the hardware meets the NH&S requirements; and (2) by the operating and supporting agency, to aid in the evaluation of the hardness impact of planned redesign, modification, or upgrade actions, and to support the purchase of spares, repair, and maintenance of hardness critical items.
