About this file
This document contains a preliminary analysis for a 28VDC power supply shelter and a draft request for proposal for the Integrated Battle Command System hardware low rate initial production/full rate production segment.
The preliminary analysis evaluates failure modes for the 28VDC power supply shelter's power supply component, identifying no output, improper output, intermittent operation, improper voltage, and short failures. It determines severity classifications and computes failure probabilities with and without redundancy from emergency offsite capabilities.
The draft RFP seeks hardware production for the Integrated Battle Command System, including maintaining approved software/firmware updates, cybersecurity, authority to operate on existing hardware, and engineering changes. The requirement includes producing hardware end items per technical data packages and the critical item development specification. The solicitation number is W31P4Q-20-R-0015 and the issuing agency is the Department of the Army Materiel Command Contracting Command at Redstone Arsenal. It specifies this is a draft for comment and not a current proposal solicitation.
