What the bill would do

The core goal is to strengthen and coordinate air and missile defense (AMD) through assessment, strategy development, and the creation of a multilateral defense framework with CENTCOM-partner nations.

1) Assessment of air and missile defense systems and interceptors (Section 2(a))

  • Timeframe: Deadline of 180 days after enactment.
  • Actions:
    • Secretary of Defense, in consultation with the Secretary of State, must complete an assessment of U.S. and foreign AMD systems and interceptors in CENTCOM’s area of responsibility.
    • Submit a congressional defense committee report detailing findings.
  • Report contents:
    • Description of current AMD systems and interceptors used by the U.S. and foreign partners.
    • Inventory and production rate analyses for AMD systems and interceptors (U.S. and partners).
    • Number of AMD systems deployed and interceptors expended since Oct 7, 2023, broken down by the U.S. and partners.
    • Assessments of systems damaged or destroyed since Oct 7, 2023.
    • Assessment of U.S. defense industry capability to fulfill orders for systems/interceptors for foreign partners (risk of sourcing from third parties).

2) Strategy for multinational AMD partnerships (Section 2(b))

  • Timeframe: Strategy and implementation plan due within 180 days of enactment.
  • Content requirements:
    • A plan for cooperation with foreign partners to implement a multinational AMD system and interceptor acquisition strategy to defend U.S. nationals/assets and partner nations.
  • Specific elements:
    • Describe current engagement with foreign partners to prioritize AMD needs, including replenishment of interceptor stock, transfer/delivery of AMD systems, and expanding regional stockpiles within CENTCOM’s area.
    • Feasibility and cost assessment of creating a stockpile within CENTCOM’s area for exclusive use by the U.S. and foreign partners.
    • Feasibility of joint ventures, licensing, and co-production between the U.S. and foreign partners to accelerate production.
    • Steps to accelerate joint R&D, development, acquisition, and transfer of alternative or lower-cost interceptor solutions; potential U.S. co-production where feasible.
    • Legal, economic, and defense policy considerations of a closer AMD acquisition partnership.
    • Lessons learned from regional AMD efforts (e.g., Ukraine, Middle East and North Africa, Caucasus, Horn of Africa).
  • Privacy/sensitivity: Activities must protect intelligence sources and methods and other sensitive information; unclassified form with a possible classified annex.

3) Missile Defense Agency Regional Working Group (Section 2(c))

  • Establishment: Within 120 days after enactment.
  • Purpose: A working group to share battlefield lessons and inform AMD requirements, and to integrate ideas into regional strategy planning.
  • Name: Multilateral Middle East Missile and Drone Defense Working Group.
  • Participants: U.S., foreign specified partners, and others as appropriate.
  • Duties:
    • Regular information exchange and best-practices development to expand AMD capacity and replenish/intercept inventories.
  • Meetings: Not fewer than every six months.
  • Reporting: Annual (and thereafter) reports to congressional defense committees, detailing:
    • Participating governments and their level of participation.
    • Meetings conducted.
    • Battlefield lessons learned and shared.
    • Identified capability gaps and recommended actions.
    • Any recommended legislative or administrative actions to improve the Working Group’s effectiveness.
  • Form: Reports to be unclassified; may include a classified annex.

4) Definitions (Section 2(d))

  • AMD systems: All related articles (air/missile defense, unmanned aerial defense, rocket defense), including sensors, control centers, launchers, etc.
  • Attacks: Missile, manned/unmanned aerial system, and rocket attacks from Iran and Iran-linked groups.
  • Foreign specified partners: Allies and partners within CENTCOM’s area.
  • Interceptors: All devices intended to detect, track, disable, or destroy incoming threats.
  • Additional terms: Clarifies scope of “area of responsibility,” reliance on CENTCOM, and congressional defense committees.

Who/What would be affected

  • U.S. Department of Defense (DoD) and the Missile Defense Agency (MDA) would lead assessments, strategy development, and the formation of the regional working group.
  • U.S. State Department would participate in consultations.
  • Foreign specified partners (CENTCOM area allies) would be engaged in joint planning, stockpiling, co-production opportunities, and information sharing.
  • Congress would receive regular unclassified (with possible classified annex) reports detailing assessments, strategy, and Working Group activities.

Key timelines and procedural aspects

  • 180-day deadline: Complete AMD assessment and submit a report to Congress.
  • 180-day deadline: Submit a strategy and implementation plan to Congress.
  • 120-day deadline: Establish the Multilateral Middle East Missile and Drone Defense Working Group.
  • Ongoing: Regular Working Group meetings (at least every six months) and annual reports to Congress.

Potential impact

  • Enhances multinational coordination for air and missile defense in CENTCOM’s area, potentially increasing resilience against Iran-related and allied threats.
  • Promotes stockpile replenishment, technology transfer, and possible joint production to accelerate AMD capacity.
  • Establishes formal mechanisms for lessons learned and continuous improvement across partners.
  • Could influence future defense budgeting, procurement, and policy actions through mandated assessments and annual reporting.
