The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure circuit card assemblies and similar replacement parts under a presolicitation notice. The procurement involves a quantity of six units of NSN 7H-5998-016082312, with delivery required to two specified locations in Pennsylvania and California. These components are critical for maintaining operational readiness, and the government has determined that it is uneconomical to reverse engineer or purchase the necessary data from additional sources. Interested parties are encouraged to contact Leigh E. Catchings at (717) 605-2864 or via email at leigh.catchings@navy.mil for further information, with a response deadline of 45 days from the notice publication date.
