The government intends to procure NSN 7H-4820-016897105-X4, quantity 8 each, with delivery to Norfolk Naval Shipyard in Portsmouth, VA. This is a sole-source action under FAR 6.302-1 because the government does not own the data rights for the part and reverse engineering is uneconomical. The notice is not a request for competitive proposals, but responsible sources may express interest and capability. Any expression of interest will be considered solely to determine whether to conduct a competitive procurement.
