This is a proposed sole-source contract for the supply of 225 "Frost" and 332 "Koch" parachute release assemblies, which are items containing explosives. The delivery schedule is to be determined, and the items require a pre-award safety survey. The government intends to negotiate with only one source, but all responsible sources may submit a capability statement for consideration. Interested parties may also identify their capability to provide a commercial alternative within 15 days of this notice. Technical data is available for viewing on SAM.gov.
