About this file
This document contains a failure modes and effects criticality analysis (FMECA) worksheet for an E001 28VDC power supply shelter and related federal contract opportunity solicitation. The FMECA worksheet analyzes potential failure modes for the power supply shelter's components, potential effects, detection methods, severity classifications, and compensating provisions. The related federal contract opportunity is a solicitation for the Integrated Battle Command System Low Rate Initial Production/Full Rate Production segment. It seeks hardware production maintaining approved software/firmware updates and meeting cybersecurity and authority to operate requirements. Engineering changes may be required. Questions are due by December 10, 2020 by 4pm Central Time. The solicitation is only for contractors who met entrance criteria on Beta SAM and were approved by the Integrated Fires Mission Command Project Office. The Department of the Army Materiel Command Contracting Command at Redstone Arsenal is the contracting agency.
