This procurement is critical as the item is flight critical, necessitating government source approval prior to contract award, and only previously approved sources will be considered for this solicitation. Interested vendors must provide comprehensive technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, as failure to do so will result in disqualification from the bidding process.
