The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two units of navigational lights under the presolicitation notice titled "62--LIGHT, NAVIGATIONAL." The procurement involves a specific National Stock Number (NSN 7H-6220-015157208) and is limited to a single source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding. These navigational lights are critical for military operations, ensuring safety and visibility in various environments. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of the notice, and they may contact Prabit Dhital at (717) 605-4358 or via email at PRABIT.DHITAL@NAVY.MIL for further information.
