The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure two units of navigational lights under the presolicitation notice. The requirement involves the acquisition of NSN 7H-6220-015157208, with the government indicating that it does not own the data or rights necessary for alternative sourcing, making it uneconomical to reverse engineer the part. These navigational lights are critical for military operations, ensuring safety and visibility in various environments. Interested vendors must submit their capabilities and interest within 45 days of the notice, and should contact Prabit Dhital at (717) 605-4358 or via email at PRABIT.DHITAL@NAVY.MIL for further details.
