Quick Summary
The Department of the Navy, NAVSUP Weapon Systems Support Mechanicsburg (NAVSUP WSS), is soliciting proposals for a STEM, FLUID VALVE (NSN 1HM 4820-01-627-6613 LI). This is a Total Small Business Set-Aside opportunity for material designated as Special Emphasis Material (Level I) due to its critical use in shipboard systems.
