Other / Unclassified

This document is a Memorandum for the Record justifying the use of other than full and open competition for an acquisition under the simplified acquisition threshold. It details the product or service being procured and the basis for selecting a sole source.

This document indicates that the government intends to procure "VITON HTFW Butterfly Valve Seat Replacements" for the USNS Lucy Stone FY 26 - WI-550. The required delivery date is July 1, 2026, with a period of performance from October 12, 2026. The justification for sole source procurement is based on "STANDARDIZATION" per COMSCINST 4790.3, to maintain fleet configuration baseline, requiring the specified make/model (VITON) for compatibility with existing equipment on vessels like the USNS Robert F. Kennedy (T-AO 208). This suggests that only vendors offering this specific brand and model will be considered for this requirement.
