Solicitation # N0038326QNB29

This contract is for the procurement of 17 units of a flight critical display processor under NSN 7R-7010-015222097-LC, with delivery terms set as FOB Origin. Due to the critical nature of the part and the fact that essential technical data and manufacturing knowledge are held by specific sources, the government requires engineering source approval from the design control activity to ensure quality. The government intends to negotiate with a single source under FAR 6.302-1, though other responsible sources may submit capability statements or proposals within the specified timeframe for consideration. Prospective bidders who are not already approved sources must submit detailed information as outlined in the NAVSUP Weapon Systems Support Source Approval Information Brochures. Failure to provide the required data or proof of a pending approval request will result in the proposal not being considered for award. The government maintains the discretion to proceed with a non-competitive award based on fleet support needs if new source approvals cannot be processed in time to meet operational requirements.

The Naval Surface Warfare Center, Crane, is seeking a two-year ordering period extension and ceiling increase for contract N0016426DGP87 to procure TR-143A Transducers, part number 7146100-302.

The government has designated this as a sole source action to avoid substantial duplication of costs, prevent unacceptable delays, and mitigate the extensive certification testing process that can take up to thirty-six months.
