These parts are used in cartridge and propellant actuated devices and components. The notice states that the item requires government source approval prior to contract award due to its flight critical nature and insufficient technical data.

Failure to provide all required data or previous submission of data will result in disqualification. The notice mentions that if source approval cannot be processed in time, the award may be based on fleet support needs. Interested parties can obtain additional documents from the DoD Single Stock Point (DODSSP) or ASSIST-Online. The notice concludes by stating that the government is not using FAR Part 12 policies for this solicitation, but interested parties can express their capability to provide commercial items within 15 days.
