DI-EMCS-82017, DATA ITEM DESCRIPTION (DID): HEMP HARDNESS MAINTENANCE AND HARDNESS SURVEILLANCE (HM/HS) PLAN (04-APR-2016)

DI-EMCS-82017, DATA ITEM DESCRIPTION (DID): HEMP HARDNESS MAINTENANCE AND HARDNESS SURVEILLANCE (HM/HS) PLAN (04-APR-2016), The High-Altitude EMP (HEMP) Hardness Maintenance (HM) and Hardness Surveillance(HS) (HM/HS) Plan describes HM and inspection procedures, HS test procedures, re-verification test procedures, supply support and training requirements, and technical data requirements for implementing the HM/HS Program described in MIL-STD-4023, section 5.3. The purpose of the HM/HS plan is to ensure that the ship-hardening is preserved throughout its service life. A HEMP HM/HS Plan is required to mitigate unacceptable degradation of the ship’s HEMP Protection Subsystem (HPS) that occurs over the life-cycle. The Plan provides the means to ensure that government prescribed methods and procedures are used by ship maintainers and that fielded ships subjected to normal wear and tear or undergoing planned modifications remain HEMP-survivable over their life-cycle. 1. This DID contains the format and content preparation instructions for data resulting from the work tasks described in section 5.3 of MIL-STD-4023 and is intended for ship systems. It is normally applied immediately after ships are delivered to a user command. 2. This DID is related to DI-EMCS-82013.
