4、 this document, or by letter. 3. This revision of MIL-STD-1766 contains a significant expansion and a complete reorganization of the 1 December 1986 version. It includes much new and revised text, as well as the incorporation of lessons learned during the application of MIL-STD-1766A to intercontine
5、ntal ballistic missile (ICBM) procurements. The key features of the revision are summarized below. 4 SAMSO STD 77-6 ( System Requirements Analysis Program for the MX Weapon System) is an essential companion document to MIL-STD-17668. 5. The scope and content of the document has been expanded in the
6、following ways: a All phases of the system life cycle are included and a more complete and balanced treatment of each phase is given. In contrast, MIL-STD-1766A focused primarily on the engineering and manufacturing development (EMD) phase and did not address the operations and support phase. b. Nuc
7、lear hardness and survivability (NH ( 2 ) guidance to SPO personnel on the generation of NH and ( 3 ) guidance on hardness critical item (HCI) identification and documentation. h. The data item descriptions (DIDs) referenced in MIL-STD-I766A, except for the test plan and test report DIDs, have been
8、revised or rewritten to reflect both lessons learned and the expanded scope and content of this revision. 6. A complete reorganization of the text has been implemented that provides greater clarity and insight into the various program elements and tasks that constitute a comprehensive NH b. treatmen
9、t of system elements in addition to CIS; c. clarification of life cycle hardness (LCH) requirements; and d. modification of contractor data requirements to enhance program efficiency and cost-effectiveness over the system life cycle; among these are: ( 1 ) a new requirement for an HCI list drawing;
10、this requirement is detailed in appendix C; ( 2 ) a new requirement for a system hardness analysis report (SHAR) to document the results of the system level hardness evaluation activity; ( 3 ) a new requirement for an NH and ( 4 ) the integration of the existing DlDs for the hardness assurance plan
11、(DI-ENVR-80263), hardness maintenance plan (DI- ENVR-80264), and hardness surveillance plan (DI-ENVR- 80265) with the DID for the NH the title of the hardness maintenance plan has been changed to “hardness maintenance preparation support plan“ to more precisely identify the documents program purpose
