The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 15 units of a control panel (NSN 7R-1680-015765564-KB) as part of a presolicitation notice. The item must be sourced from approved suppliers due to its flight-critical nature, and the procurement is restricted to those with prior government approval, as adequate technical data for alternative sources is not available. This acquisition is vital for maintaining operational readiness, and interested vendors must submit their proposals along with necessary source approval documentation to Danielle Diciacco at DANIELLE.DICIACCO.CIV@US.NAVY.MIL by the specified deadline to be considered for the award.
