The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure a rate sensor for aircraft, identified by NSN 7R-5905-015238309-H1. The procurement requires that the part be sourced from approved suppliers as it is flight critical, and no suitable technical data or manufacturing knowledge is available for alternative sources. Interested vendors must submit a source approval request along with their proposals, as the government intends to negotiate with only one source under FAR 6.302-1. For further inquiries, interested parties can contact Taylor M. O'Connor at (215) 698-2198 or via email at TAYLOR.M.OCONNOR2.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
