This opportunity involves the procurement of NSN 5990-01-462-9228, currently sourced solely from Honeywell International under a design-controlled part requiring engineering source approval. The part’s unique design and manufacturing knowledge are not economically available to the government, so only approved sources may supply it. Prospective alternate sources must qualify through the DLA Land and Maritime Alternate Offer/Source Approval Request (SAR) Program, demonstrating their product is equal to or better than the current item. No budget amounts, performance location, or submission timelines are specified in the description. Interested companies should submit qualification information directly to the contract specialist; no bid or submission deadlines are provided.
