The Department of Defense, specifically the Portsmouth Naval Shipyard, is seeking to procure calibration and repair services under a Sole Source contract. These services are required exclusively from the Original Equipment Manufacturer (OEM) due to specific authorization from NAVSEA, which mandates that only the OEM can perform the necessary calibrations for certain equipment used in submarine applications. This procurement is critical to ensure compliance with NAVSEA standards and maintain the operational integrity of the equipment. Interested parties can contact Marilyn Fletcher at marilyn.g.fletcher2.civ@us.navy.mil or by phone at 207-438-6349 for further details regarding this opportunity.
