The Department of Defense, specifically the Department of the Army, is seeking sources capable of providing repair services for the Identification Friend or Foe (IFF) interrogator sets and their secondary components. The procurement aims to restore these systems to the DoD AIMS certified configuration in accordance with the applicable revision of the DoD AIMS 1201 certification letter, as the government does not possess a competitive technical data package for these items. The IFF interrogator sets are critical for military operations, ensuring accurate identification of friendly forces, and the repairs will involve various specific components manufactured by Raytheon Technologies. Interested manufacturers must submit their capability documentation to Eric Fulmer at eric.j.fulmer.civ@army.mil by January 29, 2025, as the government will not cover any costs incurred in preparing the responses.
