The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 100 units of the Comparator Module, NSN 7H-5865-016275852, under a presolicitation notice. The procurement is for supplies that are critical to electronic countermeasures and counter-countermeasures, with the government indicating that it does not own the necessary data or rights to purchase or contract repair from additional sources, making it uneconomical to reverse engineer the part. Interested parties are encouraged to express their interest and capability to meet the requirement, with proposals due within 45 days of the notice publication, and should contact Daniel Shepley at (717) 605-7043 or via email at DANIEL.SHEPLEY@NAVY.MIL for further details.
