This contract is for NSN 7R-1680-016432918-V2, quantity 68 units, with delivery FOB origin. The item is flight-critical and restricted to government-approved sources under a source-controlled drawing, with no technical data or data rights available to support competition. Only previously approved sources are being solicited, so new sources must submit the complete Source Approval Brochure information with their proposal. Source approval can take considerable time, and award may proceed without waiting for approval if fleet support needs require it. Any offer from an unapproved source that lacks all required source approval data—or proof of prior submission—will not be considered.
