 II  119th CONGRESS  2d Session  S. 4113  IN THE SENATE OF THE UNITED STATES   March 17, 2026   Ms. Slotkin  introduced the following bill; which was read twice and referred to the  Committee on Armed Services    A BILL
To provide for limitations on the use of artificial intelligence by Department of Defense.
1.
Short title
This Act may be cited as the   AI Guardrails Act of 2026  .
2.
Limitations on use of artificial intelligence by Department of Defense
(a)
Sense of Congress
It is the sense of Congress that, consistent with America’s AI Action Plan dated July 2025, the United States must aggressively adopt artificial intelligence (AI) within its Armed Forces if it is to maintain its global military preeminence while also ensuring that the Department of Defense’s use of AI is secure and reliable.
(b)
Limitations
The Department of Defense is prohibited from using artificial intelligence as follows:
(1)
For the execution of launching or detonating a nuclear weapon.
(2)
For the monitoring, tracking, profiling, or targeting of individuals or groups in the United States, without an individualized, articulable legal basis, regardless of the origin of the data used. In no event may the Department of Defense use AI solely for the purpose of monitoring, tracking, profiling, or targeting activities protected by the First Amendment or the lawful exercise of other rights secured by the Constitution or laws of the United States.
(3)
In the employment of lethal force by autonomous weapon systems without appropriate levels of human judgment and supervision. All other uses of artificial intelligence in autonomous weapon systems shall be consistent with Department of Defense Directive 3000.09,  Autonomy in Weapon Systems,  dated January 25, 2023.
(c)
Waiver for certain autonomous weapon systems
(1)
In general
The Secretary of Defense, without delegation, may waive the prohibitions under subsection (b)(3) with respect to a system for up to one year, or renew such a waiver for up to one year, if the Secretary certifies, in writing, to the congressional defense committees that extraordinary circumstances affecting the national security of the United States require the waiver and that the probability of the system producing a result inconsistent with commander intent does not exceed the documented error rate of trained human operators performing equivalent functions under equivalent conditions.
(2)
Notifications
For each waiver issued under paragraph (1) with respect to a system, the Secretary of Defense shall notify Congress, including submission of the certification required under such paragraph, not later than 5 days after—
(A)
the issuance of a waiver for formal development of such system;
(B)
the issuance of a waiver for fielding of such system; and
(C)
any modification to such system that results in the system algorithms, intended missions sets, intended operational environments, intended target sets, or expected adversarial countermeasures to substantially differ from those granted for previously waived uses.
(3)
Elements
Each notification submitted under paragraph (1) shall include the following elements:
(A)
The rationale for the waiver.
(B)
A description of the autonomous weapon system or technology covered by the waiver.
(C)
A description of the operational parameters and safeguards for the system, including:
(i)
Assessments of system performance, capability, reliability, effectiveness, and suitability under realistic conditions.
(ii)
A description of the associated training, doctrine, and tactics, techniques, and procedures.
(iii)
The timeframe and geographic area of intended use.
(iv)
A description of measures taken to minimize the probability and consequences of unintended engagements or failures.
(v)
Clear procedures for trained operators to activate and deactivate system functions.
(vi)
Post-deployment continuous monitoring mechanisms.
(vii)
Results from the realistic system developmental and operational testing and evaluation that demonstrate the probability of the system misidentifying a target, taking unintended action, or producing a result inconsistent with commander intent does not exceed the documented error rate of trained human operators performing equivalent functions under equivalent conditions.
(D)
The anticipated duration of the waiver.
(4)
Form
A notification under paragraph (1) shall be submitted in unclassified form, but may include a classified annex, as the Secretary determines necessary.
(d)
Artificial intelligence defined
In this section, the term  artificial intelligence  has the meaning given such term in section 5002 of the National Artificial Intelligence Initiative Act of 2020 ( 15 U.S.C. 9401 ).
