The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of five drive shaft couplings as part of a Foreign Military Sales (FMS) spares purchase. This amendment to the solicitation increases the quantity from four to five, reflecting the updated requirement for these components, which are critical for helicopter rotor blades and drive mechanisms. The procurement is not set aside for small businesses, as determined by the Small Business Administration representative, and all other terms and conditions of the solicitation remain unchanged. Interested parties can contact Anna M. Kiessling at 215-697-3752 or via email at ANNA.M.KIESSLING.CIV@US.NAVY.MIL for further details.
