This acquisition is critical as it involves supplies for which the government does not possess complete technical data, thus limiting the solicitation to approved sources, specifically Electric Boat Corporation. Interested suppliers must be certified by the Department of Defense to access the militarily critical technical data associated with this procurement, with the solicitation expected to be available on or after October 31, 2025, via the DIBBS website.
