The Department of Homeland Security, specifically the U.S. Coast Guard, is seeking quotations for the procurement of 40 raw water pump assemblies (Part Number: E23535447; NSN: 2930-01-590-4200) necessary for the operation of its 47' Motor Lifeboat vessels. These assemblies are critical components of the steering system, and the procurement is justified as a sole source requirement due to the proprietary nature of the technical data and manufacturing drawings, which are exclusively held by DTNA. Interested vendors must submit their quotations by May 20, 2025, with delivery required on or before June 20, 2025, and should direct inquiries to Yannick Kassi at Yannick.A.Kassi@uscg.mil.
