The Department of Defense, through the NAVSUP Weapon Systems Support office, intends to solicit a sole source contract for the repair of HF Couplers from Rockwell Collins, the Original Equipment Manufacturer (OEM). This procurement is critical as the government does not possess the necessary data or rights to source these repairs from alternative suppliers, making Rockwell Collins the only known source capable of fulfilling this requirement. Interested parties have 15 days to express their interest and capability to meet the government's needs, with a final deadline for proposals set at 45 days from the publication of this notice. For further inquiries, interested organizations may contact Alyssa Thieu at alyssa.t.thieu.civ@us.navy.mil.
