The Department of Defense, through the Naval Research Laboratory (NRL), is seeking information from potential sources for small satellite survey optics as part of a Request for Information (RFI). The objective is to identify fast, moderate-to-large aperture space telescopes suitable for deployment on Evolved Secondary Payload Adapter (ESPA)-class small satellites, aimed at enhancing optical space domain awareness (SDA) capabilities. These optics are critical for detecting objects at significant ranges while maintaining a wide field of view, with specific technical requirements including an aperture diameter of 0.1m to 0.5m, F/3 or less, and a mission life of three years or more in various orbital regimes. Interested parties are encouraged to submit a Capabilities Statement by email to Richard Waterstreet at richard.j.waterstreet2.civ@us.navy.mil, detailing their qualifications and relevant past performance, with responses due by the specified deadline. This RFI does not constitute a formal solicitation, and no awards will be made from this announcement.
