The Department of Defense, through the Naval Research Laboratory, is seeking potential sources for a Research and Development contract focused on Electro-Optical (EO) and Infrared (IR) technologies to enhance capabilities in Advanced Communications, Intelligence, Surveillance, Reconnaissance (ISR), and Electronic Warfare (EW) for the U.S. Navy and Marine Corps. The objective is to provide specialized support in systems engineering, technical engineering, and the development of both new and existing systems, particularly in the area of visible, electro-optic, and infrared sensors. This initiative is critical for maintaining a leadership position in optical technologies that improve situational awareness and self-protection against advanced threats, aligning with broader defense objectives. Interested parties are encouraged to submit their capabilities and relevant experience via email to Deborah Whang at deborah.s.whang.civ@us.navy.mil, with responses due by the specified deadline, and should reference "N00173-25-RFI-DW01" in their correspondence.
