XX(a)--RIN 1400-AG35.

SUPPLEMENTARY INFORMATION: The Department of State's Directorate of 
Defense Trade Controls (DDTC) administers the ITAR (22 CFR parts 120 
through 130) to, among other things, regulate the export, reexport, 
retransfer, and temporary import of defense articles and defense 
services described on the USML at ITAR Sec.  121.1. Items not subject 
to the ITAR or to the exclusive licensing jurisdiction of certain other 
departments or agencies of the U.S. Government are subject to the 
Export Administration Regulations (EAR) (15 CFR parts 730 through 774), 
which include the Commerce Control List (CCL) in Supplement No. 1 to 
part 774. The EAR is administered by the Department of

[[Page 59064]]

Commerce, Bureau of Industry and Security (BIS). This rule does not 
modify the list of defense articles and defense services controlled for 
purposes of permanent import by the Attorney General, as enumerated on 
the U.S. Munitions Import List (USMIL) at 27 CFR 447.21.
    Section 38 of the Arms Export Control Act (AECA) (22 U.S.C. 2778) 
requires periodic review of the USML to determine which articles and 
services, if any, no longer warrant designation. In maintaining the 
USML, DDTC identifies articles and services for potential addition to 
or removal from the USML, or for clarification on how they are 
described on the USML, through a variety of methods. This can include 
public feedback and interagency consultations, commodity jurisdiction 
reviews, advisory opinions, and technology monitoring. The Department 
maintains the USML such that it comprises those defense articles or 
defense services that provide a critical military or intelligence 
advantage. The Department, informed by consultations with its 
interagency partners, and with the concurrence of the Department of 
Defense, has determined that those articles and services this rule 
removes from the USML no longer warrant ITAR control.
    USML Category XX(a)(10) describes certain vessels with a gross 
weight rating exceeding 3,000 pounds that are designed to operate 
without human interaction for longer than 24 hours or for more than 70 
nautical miles. The license exemption at ITAR Sec.  126.9(u) authorizes 
certain transfers of vessels described in USML Category XX(a)(10).
    The Department, with the concurrence of the Department of Defense, 
now assesses that vessels described in USML Category XX(a)(10) with a 
gross weight rating up to 8,000 pounds only provide a critical military 
or intelligence advantage when they are described elsewhere on the USML 
or when they are specially designed to possess certain navigation 
capabilities. Based on this assessment, the Department is revising 
paragraph (a)(10) to continue describing vessels at or under 8,000 
pounds only if they are specially designed to have navigation 
capabilities beyond the ability to (1) follow fixed waypoints and (2) 
perform collision avoidance maneuvers that adhere to the see-and-avoid 
principles of navigation regulations. The Department is also revising 
paragraph (a)(10) to use the term ``specially designed,'' which is 
defined in Sec.  120.41, to improve the clarity of the control text. 
The Department is also adding a new paragraph (a)(11) and moving 
vessels with a gross weight rating exceeding 8,000 pounds that are 
specially designed to operate without human interaction for longer than 
24 hours or for more than 70 nautical miles, to paragraph (11) from the 
current paragraph (10). This rule does not modify the license exemption 
at Sec.  126.9(u); the provisions in that exemption remain available 
for vessels described in USML Category XX(a)(10). The Department also 
makes conforming changes to paragraph (a)(9) in this rule. The 
Department also notes its intent to review the ITAR controls on 
autonomous capabilities, including the maritime navigation systems 
described in USML Category VI.

Request for Comments

Specific Comments Requested

    The Department encourages the public to provide comments related to 
this rule, as well as comments specifically responsive to the questions 
described in this section. To facilitate timely review and assessment, 
comments should be provided in a concise sentence or paragraph, 
followed by supporting explanatory paragraphs and examples, with each 
distinct comment treated separately as opposed to multiple comments in 
one paragraph or section. The Department encourages commenters to 
include supporting facts, research, and evidence in their comments. 
When doing so, commenters are encouraged to provide citations to any 
published materials referenced.
    1. Are there other navigation capabilities the Department should 
consider in order to refine the updated navigation system criteria in 
the new USML Category XX(a)(10)?
    2. Section Sec.  126.9 includes a licensing exemption for certain 
activities using UUVs described in USML Category XX(a)(10).
    a. What challenges, if any, have operators of vessels described in 
the new USML Category XX(a)(10) encountered in using the exemption? How 
could the Department revise the exemption to mitigate those challenges 
while continuing to protect U.S. national security interests?
    b. Are there additional activities the Department should consider 
adding to the list of authorized purposes in Sec.  126.9(u)(2)(iii)?

Comment Submission Instructions

    Include the Regulatory Information Number (RIN) (1400-AG35) for all 
submissions related to this rule and follow the submission instructions 
contained in the ADDRESSES section above. Parties who wish to comment 
anonymously may do so by submitting their comments via

commenter blank and including no identifying information in the comment 
itself. Commenters are cautioned not to include proprietary, export-
controlled, personal, or other sensitive information in their comments 
that they would not want to be made public. If such information would 
provide useful insight to the comment: (1) assemble that information in 
a separate document with relevant markings; (2) include ``[Proprietary] 
supplement on file with: [provide POC]'' as the first line in the body 
of the email submission; (3) submit the public portion of the comment 
via email; and (4) call DDTC at (202) 663-1282 to coordinate submission 
of the proprietary supplement.

Regulatory Analysis and Notices

Administrative Procedure Act

    This rulemaking is exempt from the rulemaking requirements of the 
Administrative Procedure Act (APA) pursuant to 5 U.S.C. 553(a)(1) as it 
involves a military or foreign affairs function of the United States. 
Nevertheless, and without prejudice to this determination, the 
Department seeks public comments in this rule.

Regulatory Flexibility Act

    Since this rule is exempt from the notice-and-comment rulemaking 
provisions of 5 U.S.C. 553, it does not require analysis under the 
Regulatory Flexibility Act.

Unfunded Mandates Reform Act of 1995

    This rulemaking does not involve a mandate that will result in the 
expenditure by state, local, and tribal governments, in the aggregate, 
or by the private sector of $100 million or more in any year and it 
will not significantly or uniquely affect small governments. Therefore, 
no actions are deemed necessary under the provisions of the Unfunded 
Mandates Reform Act of 1995.

Congressional Review Act

    The Office of Information and Regulatory Affairs has found that 
this rule is not a major rule under the criteria of 5 U.S.C. 804(2).

Executive Orders 12372 and 13132

    This rulemaking does not have sufficient federalism implications to 
require consultations or warrant the preparation of a federalism 
summary impact statement. The regulations implementing Executive Order 
12372

[[Page 59065]]

regarding intergovernmental consultation on Federal programs and 
activities do not apply to this rulemaking.

Executive Orders 12866 and 13563

    Executive Order 12866, as supplemented and affirmed by Executive 
Order 13563, directs agencies to assess all costs and benefits of 
available regulatory alternatives and, if regulation is necessary, to 
select regulatory approaches that maximize net benefits (including 
potential economic, environmental, public health and safety effects, 
distributed impacts, and equity). Executive Order 13563 emphasizes the 
importance of quantifying both costs and benefits, of reducing costs, 
of harmonizing rules, and of promoting flexibility. After review by the 
Office of Management and Budget (OMB), this rule has been deemed to be 
a ``significant regulatory action'' under section 3(f) of Executive 
Order 12866.
    This rule was undertaken pursuant to a statutory directive to 
periodically review the items on the USML. The Department generally 
determines which items warrant addition to, or removal from, the USML 
by assessing whether each provides a critical military or intelligence 
advantage based on national security and foreign policy considerations. 
Because the costs and benefits of changing what is controlled focus on 
the effect or utility of the item or service, rather than its market 
prevalence or economic value, quantitative analyses cannot be usefully 
estimated and are not available, particularly since the global 
prevalence or availability of the item or service are not known. 
Qualitatively, the rule was assessed for costs and benefits. These 
revisions are also informed by confidential requests for commodity 
jurisdiction determinations and advisory opinions, submitted by 
industry. The Department takes into account common questions and 
strives to streamline and simplify USML paragraphs based on how it 
understands industry experience with certain parts of the USML.
    This rule removes the designation of certain defense articles by 
revising USML Category XX(a). Vessels removed from the scope of USML 
Category XX(a)(10), that are not described elsewhere on the USML, will 
become subject to the EAR. This action reduces the regulatory 
requirements associated with the removed vessels. The Department 
assesses the vessels removed by this rule do not warrant control under 
the ITAR. The Department assesses the benefits of this rulemaking 
outweigh any costs, that modifying the USML in this manner is the most 
cost-effective method to achieve the Department's regulatory objectives 
on this matter, and that doing so will result in a net reduction of the 
burden on the regulated community.
    The alternative to this rule was inaction or delay. The Department 
could have waited to amend larger parts of the USML at once or 
continued to gather data to evaluate the controls affected by this 
rule. These alternatives were rejected. Statutory requirements, 
including section 38(f) of the Arms Export Control Act (22 U.S.C. 
2778(f)), and section 1345 of the National Defense Authorization Act 
for Fiscal Year 2024, require a periodic review of the USML for edits 
like those made by this rule. While the Department continuously reviews 
the entire USML, it aims to implement most revisions through rules that 
are focused on specific items or subsets of the USML.

Executive Order 14192

    This rule is exempt from Executive Order 14192 as it is a 
regulation issued with respect to a foreign affairs or national 
security function of the United States.

Executive Order 12988

    The Department of State has reviewed this rulemaking in light of 
sections 3(a) and 3(b)(2) of Executive Order 12988 to eliminate 
ambiguity, minimize litigation, establish clear legal standards, and 
reduce burden.

Executive Order 13175

    The Department of State has determined that this rulemaking will 
not have tribal implications, will not impose substantial direct 
compliance costs on Indian tribal governments, and will not preempt 
tribal law. Accordingly, the requirements of Executive Order 13175 do 
not apply to this rulemaking.

Paperwork Reduction Act

    This rulemaking does not impose or revise any information 
collections subject to 44 U.S.C. chapter 35.

List of Subjects in 22 CFR Part 121

routes using fixed waypoints, station-keeping, or performing collision 
avoidance maneuvers that adhere to the see-and-avoid principles of 
navigation regulations; or
    Note 1 to paragraph (a)(10)(ii): An example of ``see-and-avoid 
principles of navigation regulations'' are those that implement 
relevant sections of the International Regulations for Preventing 
Collisions at Sea (COLREGs) such as Rules 5 (look-out), 8 (action to 
avoid collision), and 13 through 18 (various actions and 
responsibilities between vessels).
