The Department of Defense, specifically the Department of the Air Force, is conducting a Request for Information (RFI) to identify potential sources for the procurement, repair, or redesign of the Keyer Driver/Modulator Subassembly CCAs for the AN/MST-T1A Multiple Threat Emitter System (MUTES). This initiative is crucial for simulating hostile radar threats during pilot training, and the government seeks Form, Fit, Function, and Interface (FFFI) replacements, along with the capability to perform in-system acceptance tests at Tobyhanna Army Depot. Interested contractors must be valid DoD contractors with active SAM registration and are encouraged to provide a rough order of magnitude (ROM) cost estimate in their responses, which are due within 30 days. For further inquiries, interested parties can contact Joel Duran at joel.duran@us.af.mil or James Kincaid at james.kincaid.2@us.af.mil.
