The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of four units of the Heads Up Computer, identified by NSN 7R-1680-015887538-P8 and reference number 1500-2460-004. This procurement involves a commercial/nondevelopmental/off-the-shelf item that requires Government source approval prior to contract award due to its flight-critical nature, necessitating that only previously approved sources are solicited. Interested vendors must submit the required technical data and source approval documentation with their proposals, as offers lacking this information will not be considered. For further inquiries, Antonio Fiocca can be contacted at (215) 737-0118 or via email at ANTONIO.FIOCCA@DLA.MIL.
