The Department of Defense, specifically the Naval Sea Systems Command (NAVSEA), is conducting a sources sought notice to identify potential sources capable of manufacturing the Over the Horizon – Weapons System (OTH-WS) and providing Design Agent support. This procurement aims to enhance the U.S. Navy's capabilities in long-range anti-ship warfare by supplying 516 Encanistered Missiles (EM) and associated systems, which are designed to operate effectively in hostile environments without requiring further guidance after launch. Interested parties are encouraged to submit their responses to the market survey questionnaire by December 31, 2025, to the designated contacts, including Brittany Burton at brittany.m.burton4.civ@us.navy.mil and Jamal Newman at jamal.e.newman.civ@us.navy.mil, as the government will not accept unsolicited proposals or reimburse any costs associated with the responses.
