The Department of Defense, through the Naval Research Laboratory, is seeking potential sources for a contract focused on Research and Development in Electro-Optical (EO) and Infrared (IR) technologies to enhance capabilities in Advanced Communications, Intelligence, Surveillance, Reconnaissance (ISR), and Electronic Warfare (EW). 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 crucial for maintaining a leadership position in optical technologies that improve situational awareness and self-protection capabilities against advanced threats. Interested parties are encouraged to submit their responses, including company information and technical capabilities, to Deborah Whang at deborah.s.whang.civ@us.navy.mil by the specified deadline, with the understanding that this is a sources sought notice and not a solicitation for proposals.
