This procurement is critical as the item is flight critical, necessitating government source approval prior to contract award; only previously approved sources will be considered, and new sources must submit detailed information as outlined in the NAVSUP Source Approval Information Brochures. Interested parties are encouraged to review the relevant specifications and submit their proposals along with the required documentation by the specified deadline, with inquiries directed to Connor C.
