ACAS-X deployment plan

Full Title:
Military Next-Gen Collision Avoidance Act of 2026

Summary#

The bill requires the Secretary of Defense to send Congress a plan for deploying the Airborne Collision Avoidance System‑X family (ACAS‑X and variants). The plan must be delivered within 180 days and must describe roadmaps, testing and certification needs, interoperability with ADS‑B equipment, safety benefits, and any recommended administrative or legislative steps. The Secretary may act to implement the plan and must brief the Armed Services committees within 30 days after submitting the plan.

  • Main change: Directs the Department of Defense to prepare and deliver an action plan for widespread military use of ACAS‑X and related systems.
  • Key contents required: strategic roadmap; actions and funding needed for research, development, testing, evaluation, and standards for certification; interoperability with ADS‑B Out/In (including rotorcraft); safety assessment; recommendations for further action.
  • Timeline: plan due within 180 days of enactment; briefing to committees within 30 days after submission.
  • Who must act: Secretary of Defense and the Department of Defense.
  • Definitions: the bill references ADS‑B Out and ADS‑B In as defined in existing FAA regulations.

What it means for you#

  • Military aircrews and operators: This could lead to a formal plan to equip military aircraft with ACAS‑X systems. Over time, that may mean new onboard collision‑avoidance equipment, updated procedures, and training.
  • Rotorcraft pilots (military): The bill specifically asks for interoperability considerations for rotorcraft, so rotorcraft operations may be examined for special technical or certification needs.
  • Department of Defense: Must prepare the action plan, include funding needs, and may take steps to implement parts of the plan.
  • Congress (Armed Services Committees): Will receive the plan and a follow‑up briefing and may use that information to seek funding, pass laws, or oversee implementation.
  • Defense contractors and avionics suppliers: Could be asked to support research, testing, certification, and procurement if the DoD moves to adopt ACAS‑X widely.
  • Taxpayers / budget process: The bill itself does not appropriate money, but it asks the DoD to identify funding needs. Future budget requests could follow.

Expenses#

No publicly available information.

  • The bill does not include specific funding or a fiscal estimate in the text provided.
  • The action plan must list actions and funding necessary for research, development, testing, evaluation, and standards development; this suggests future budget requests may follow but does not specify amounts.
  • Potential future costs (inferred): equipment purchases or retrofits for aircraft, testing and certification costs, training for aircrews and maintainers, and program management within DoD.
  • The Secretary “may” implement the plan, which could trigger further spending if DoD decides to move forward. The bill does not say how implementation would be funded.

Proponents' View#

  • The bill appears intended to accelerate DoD planning for next‑generation collision avoidance across military aircraft.
  • A possible argument for the bill is that it would create a clear, time‑bound roadmap for adoption, testing, and certification of ACAS‑X technologies.
  • The required interoperability analysis could help ensure military ACAS‑X works with ADS‑B Out/In systems used in civil airspace and reduce mid‑air conflict risks.
  • Requiring the DoD to identify actions and funding needs could improve transparency and give Congress better information when deciding budgets or laws.

Opponents' View#

  • One concern is that the bill does not provide funding. It only asks the DoD to identify funding needs, so planning could create expectations of future costs without a current funding source.
  • The bill does not set standards or requirements for when or how equipment must be installed. It is unclear whether the plan must lead to mandatory deployment or only recommendations.
  • The 180‑day deadline may be short for a full technical and certification assessment across many aircraft types, especially rotorcraft with unique flight characteristics.
  • The bill does not detail how interoperability and certification with civilian ADS‑B rules will be resolved, which could be technically and legally complex.
  • It is unclear what authority or oversight will be used if the Secretary decides to implement parts of the plan without additional Congressional action.
