IndNational Security Assessment: U.S. Defense Supply Chain Network Sector-by-Sector, Tier-by-Tier (S2T2)


The U.S Department of Commerce, Bureau of Industry and Security (BIS), Office of Technology Evaluation, in coordination with the U.S. Department of Defense (DoD), Office of Manufacturing and Industrial Base Policy, is conducting an industrial base survey of DoD's supply chain network. The principal goal of this effort is to produce a sector-by-sector, tier-by-tier (S2T2) evaluation of the defense industrial base with a specific focus on the aircraft, ground systems, missiles, missile defense, services and shipbuilding sectors. The results will provide DoD with a comprehensive understanding of the defense supply chain network as a benchmark to plan for future technological, market, and budget challenges that could impact U.S. military capabilities and readiness.

Your facility has been identified as a supplier in the DoD supply chain network and selected to participate in this assessment. To begin, download and save the Microsoft Excel formatted survey and corresponding instructions from the below Excel icon. To help guide your data collection efforts, PDF versions of the Excel survey template, glossary and related DoD acquisition categories (ACATs) are also made available here. BIS will only accept Excel survey submissions. The PDF version of the survey does not contain essential drop-down response criteria held in the Excel version.

In select instances, multiple facilities under the same corporation, business unit, or division have received a letter from BIS. If your company or facility received multiple letters, do not consolidate your responses into a single submission. BIS requires a facility-level response from all letter recipients. Please notify the Senior Compliance Specialist below immediately if a facility-level response is not feasible.
