The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure repair services for the Radar Set Subassembly, specifically for the E-2D aircraft, from Lockheed Martin Corporation. This procurement is intended to be conducted on a sole source basis, as Lockheed Martin is the Original Equipment Manufacturer (OEM) and the only known source capable of providing the necessary repair support due to the lack of available drawings or data for alternative suppliers. Interested parties have 15 days from the notice to express their interest and capability, with a final deadline for proposals set at 45 days post-publication, although the contract is expected to be awarded to Lockheed Martin. For further inquiries, interested organizations may contact Dina Wojciechowski at 215-697-1219 or via email at dina.m.wojciechowski.civ@us.navy.mil.
