The government intends to solicit a hydraulic motor-pump on a sole source basis due to lacking sufficient data to contract with other than the current source. The acquisition is for one unit and is subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement. This item requires Government Source Approval prior to award, and only approved sources or those submitting the required source approval data will be considered. Interested parties must obtain and follow the NAVSUP WSS Source Approval Brochure to be eligible. For questions, contact the designated government representative.
