The procurement involves a quantity of 10 units of NSN 0R-0098-LLZ98S445-CC, and the government does not possess sufficient data to contract with sources other than the current supplier, necessitating government source approval prior to award. These items are critical for military operations and are subject to various trade agreements, emphasizing the importance of compliance with the NAVSUP WSS Source Approval Brochure for interested vendors.
