This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only sources previously approved by the government will be considered. Interested vendors must submit the necessary documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to provide the required data will result in disqualification from the award process.
