ARISING FROM THE GLOBAL PROLIFERATION AND MALICIOUS USE
OF UNMANNED AIRCRAFT SYSTEMS.
(a) In General.--Title III of the Homeland Security Act of 2002 (6
U.S.C. 231 et seq.) is amended by adding at the end the following new
section:
``SEC. 324. ANNUAL ASSESSMENT ON TERRORISM THREATS TO THE UNITED STATES
RELATING TO THE USE OF UNMANNED AIRCRAFT SYSTEMS BY
COVERED FOREIGN ADVERSARIES, INCLUDING TERRORIST
ORGANIZATIONS.
``(a) In General.--Not later than 270 days after the date of the
enactment of this section and annually thereafter for six years, the
Secretary shall submit to the appropriate congressional committees an
assessment of terrorism threats to the United States relating to the
global proliferation and malicious use of covered unmanned aircraft
systems by covered foreign adversaries, including terrorist
organizations, and the resulting implications such activities present
for the homeland security of the United States, including implications
for domestic preparedness for the malicious use of unmanned aircraft
systems and the collective response to related terrorism threats.
``(b) Matters Included.--Each assessment of terrorism threats under
subsection (a) shall include the following:
``(1) An analysis of the methods, trends, tactics, and
technologies, as of the date of such assessment, by which
covered foreign adversaries, including terrorist organizations,
seek to use covered unmanned aircraft systems to surveil,
disrupt, damage, or destroy critical infrastructure of the
United States or a foreign country, target civilian
populations, conduct kinetic strikes or terrorism attacks, or
otherwise undermine public safety or regional stability.
``(2) An evaluation of the risks that such methods, trends,
tactics, and technologies may be replicated, adapted, or
learned from by other covered foreign adversaries, including
terrorist organizations, or by lone actors or domestic violent
extremists, to carry out similar terrorist attacks within the
homeland, including efforts to compromise border security or
port security, exploit vulnerabilities in the homeland's
transportation systems, soft targets, mass gathering events, or
other high-risk venues, or to cause mass casualties or
disruption through the use of covered unmanned aircraft
systems.
``(3) An assessment of how covered unmanned aircraft
systems are employed for intelligence, surveillance, or
reconnaissance purposes by covered foreign adversaries,
including terrorist organizations, including the collection,
transmission, or exploitation of imagery or geospatial data,
and how such data could be leveraged to facilitate espionage,
cross-border operations, or attacks against critical
infrastructure of the United States.
``(4) An analysis of how covered foreign adversaries,
including terrorist organizations, acquire, manufacture,
smuggle, or divert covered unmanned aircraft systems into
conflict zones, including via ground convoys, commercial
shipping containers, rail shipments, small vessels, fixed- or
rotary-wing aircraft, over-the-road freight transport that may
conceal or co-transport other illicit or seemingly innocuous
goods, or any other illicit trafficking networks, and the
applicability of such methods to potential entry into the
homeland through seaports, airports, or land border crossings.
``(5) An analysis of emerging technologies integrated into
covered unmanned aircraft systems that enhance their
operational effectiveness, resilience, and lethality, when used
by covered foreign adversaries, including terrorist
organizations, including the use of artificial intelligence,
autonomous navigation and targeting systems, advanced
surveillance sensors, precision-guided payloads, encrypted
communications links, physical tethering mechanisms (such as
fiber optic cables that enable uninterrupted command and
control in contested environments), cybersecurity-resilient
architectures designed to prevent intrusion or remote
exploitation, or any other adaptations intended to defeat or
bypass electronic warfare countermeasures through resistance to
jamming, spoofing, or signal degradation.
``(6) An evaluation of the use of low-cost, high-volume
swarms of covered unmanned aircraft systems deployed by covered
foreign adversaries, including terrorist organizations, in any
region of active conflict as determined by the Secretary, in
consultation with the heads of other relevant Federal
departments or agencies the Secretary determines appropriate,
and the extent to which similar swarm tactics could overwhelm
law enforcement within the homeland or overwhelm homeland
defense systems, including the potential to exhaust counter-UAS
systems and associated resources or create mass panic.
``(7) An assessment of the use of covered unmanned aircraft
systems by covered foreign adversaries, including terrorist
organizations, in any region of active conflict as determined
by the Secretary, in consultation with the heads of other
relevant Federal departments or agencies the Secretary
determines appropriate, to deliver chemical, biological,
radiological, or nuclear payloads or simulants, including
efforts to repurpose agricultural or industrial spraying
unmanned aircraft systems for nonconventional attacks, and
whether such scenarios are adequately modeled or prepared for
in homeland security planning.
``(8) A review of how covered foreign adversaries,
including terrorist organizations, in any region of active
conflict as determined by the Secretary, in consultation with
the heads of other relevant Federal departments or agencies the
Secretary determines appropriate, have experimented with water-
launched unmanned aircraft systems and unmanned aircraft
systems deployed from shipping containers or disguised
vehicles, and the implications such tactics may pose for port
security, land border security, or the security of critical
infrastructure of the United States or a foreign country in
proximity to seaports within the homeland.
``(9) An assessment of lessons learned from ongoing and
recent global conflicts regarding the utilization, defense, and
defeat of covered unmanned aircraft systems, and from the
experiences of allied and partner countries in countering
unmanned aircraft system-enabled attacks conducted by covered
foreign adversaries, including terrorist organizations,
including an evaluation of the effectiveness of mobile counter-
UAS system platforms, passive detection and tracking
technologies, airspace management and deconfliction tools, and
regulatory mechanisms (such as drone zoning laws), the
applicability of such lessons to Federal, State, and local
homeland security operations, and the manner in which the
Department has incorporated, or plans to incorporate, such
lessons into its homeland security planning, counter-UAS
systems strategy, and interagency coordination activities.
``(10) An assessment of the adoption, adaptation, and
potential operational use of unmanned aircraft systems by
transnational criminal organizations, cartels, or other illicit
groups in the Western Hemisphere that are supplied by or
emulating covered foreign adversaries, including terrorist
organizations, including cross-border weaponization trends,
narcotics trafficking, and surveillance of law enforcement
operations.
``(11) A review of the Department's research and
development efforts to counter emerging threats posed by
covered unmanned aircraft systems used by covered foreign
adversaries, including terrorist organizations, and how such
efforts contribute to domestic preparedness for and collective
response to terrorism.
``(12) A description of how the Secretary has incorporated
input, technology, and best practices from private sector
entities, including such entities the counter-UAS systems or
detection technologies of which are currently deployed in
regions of active conflict as determined by the Secretary, in
consultation with the heads of other relevant Federal
departments or agencies the Secretary determines appropriate,
involving covered foreign adversaries, including terrorist
organizations, in order to strengthen domestic preparedness and
accelerate adoption of effective counter-UAS system
capabilities.
``(13) Any other matter relating to covered unmanned
aircraft systems the Secretary determines appropriate.
``(c) Training and Capacity Building.--To enhance domestic
preparedness against terrorism threats assessed in accordance with
subsection (a), the Secretary, in consultation with the heads of
