NAVSUP WSS Philadelphia intends to award a sole-source repair contract for 4 units of a radio frequency switch (NSN 7R-5985-002395847-LZ) to Rockwell Collins Inc., the original equipment manufacturer. The government does not own the data or rights needed to source this part elsewhere, and no drawings or data are available. Other responsible sources may submit a capability statement or Source Approval Request, but the procurement will not be delayed for approval. The contract will have a one-year duration, delivery will be FOB origin, and UID and Buy American clauses will apply. This notice is not a request for competitive proposals.
