NAVSUP Weapon Systems Support Philadelphia intends to award a sole-source, one-year repair contract to Rockwell Collins, Inc. for four circuit card assemblies, as they are the original equipment manufacturer and the only known source. The government does not own the data or rights needed for alternative sourcing, and no drawings are available. Performance will be at the contractor's location, with UID and Buy American clauses applying. All responsible sources may submit a capability statement or proposal within 45 days of this synopsis, though the procurement will not be delayed for source approval requests. No budget amount is specified.
