This is a solicitation for 30 units of a commercial, off-the-shelf, flight-critical part. The government requires delivery FOB Origin. Only sources previously approved by the government for this specific item have been solicited, and new sources face a lengthy approval process that typically precludes delaying an award. Unapproved offerors must submit a detailed source approval package with their proposal, following specific NAVSUP WSS brochures. Offers lacking the complete required source approval data will not be considered for award.
