Defense Primer: Emerging Techn
Both the 2018 National Defense Strategy and senior U.S.
defense and intelligence officials have identified a number
of emerging technologies that could have a disruptive
impact on U.S. national security in the years to come. These
technologies include

artificial intelligence,
lethal autonomous weapons,
hypersonic weapons,
directed energy weapons,
biotechnology, and
quantum technology.

As these technologies continue to mature, they could hold
significant implications for congressional oversight, U.S.
defense authorizations and appropriations, military concepts
of operations, and the future of war.
Artificial Intelligence.....
Although there is no official U.S. government definition of
artificial intelligence (AI), Al generally refers to a computer
system capable of executing tasks requiring human-level
cognition. Al is currently being incorporated into a number
of military applications, including intelligence, surveillance,
and reconnaissance; logistics; cyber operations; command
and control; and semi-autonomous and autonomous
vehicles. As it develops, Al could enable new concepts of
operations, such as swarming (i.e., cooperative behavior in
which uninhabited vehicles autonomously coordinate to
achieve a task), that could present both challenges and
opportunities for the U.S. military.
Recent news reports and analyses have highlighted the role
of Al in enabling increasingly realistic photo, audio, and
video digital forgeries, popularly known as deep fakes.
Adversaries could potentially deploy this Al capability as
part of their information operations in a gray zone
conflict. Deep fake technology could be used against the
United States and its allies to generate false news reports,
influence public discourse, erode public trust, and attempt
to blackmail diplomats. Some have suggested that Al could
be used to create full digital patterns-of-life, in which an
individual's digital footprint is mapped against other
personal information, such as spending habits and job
history, to create comprehensive behavioral profiles of
servicemembers, suspected intelligence officers,
government officials, and private citizens. Similar to deep
fakes, this information could, in turn, be used for targeted
influence operations or blackmail.
In June 2018, the Pentagon established the Joint Artificial
Intelligence Center (JAIC, pronounced jake) to
coordinate defense-wide Al efforts. Effective February 1,
2022, the position of Chief Digital and Al Officer (CDAO)
is to be established, reporting directly to the Deputy

Secretary of Defense. The CDAO is to serve as the
Department's senior official responsible for strengthening
and integrating data, artificial intelligence, and digital
solutions in the department, with the Office of the CDAO
serving as the successor organization to the JAIC. In
addition, the FY2019 National Defense Authorization Act
(P.L. 115-232, §1051) established a National Security
Commission on Artificial Intelligence to assess U.S.
competitiveness in Al and offer recommendations to
Congress. The commission concluded in October 2021.
Lethal Autonomous Weapons
Lethal Autonomous Weapon Systems (LAWS) are a class
of weapon systems capable of independently identifying a
target and employing an onboard weapon system to engage
and destroy the target without manual human control.
LAWS require computer algorithms and sensor suites to
classify an object as hostile, make an engagement decision,
and guide a weapon to the target. This capability would
enable the system to operate in communications-degraded
or -denied environments where traditional systems may not
be able to operate.
LAWS are not yet in widespread development, and some
senior military and defense leaders have expressed concerns
about the ethics of ever fielding such systems. For example,
in 2017 testimony before the Senate Armed Services
Committee, then-Vice Chairman of the Joint Chiefs of Staff
General Paul Selva stated, I do not think it is reasonable
for us to put robots in charge of whether or not we take a
human life. Currently, there are no domestic or
international legal prohibitions on the development of
LAWS; however, an international group of government
experts has begun to discuss the issue. Approximately 30
countries have called for a preemptive ban on the systems
due to ethical considerations, while others have called for
formal regulation or guidelines for development and use.
DOD Directive 3000.09 establishes department guidelines
for the development and fielding of LAWS to ensure that
they comply with the law of war, applicable treaties,
weapon system safety rules, and applicable rules of
engagement.
Hypersonic Weapons
Hypersonic weapons-which fly at speeds of at least Mach
5-are in development in a number of countries, including
the United States. There are two categories of hypersonic
weapons:
 Hypersonic glide vehicles (HGV) are launched from a
rocket before gliding to a target. (When HGVs are
mated with their rocket booster, the resulting weapon
system is often referred to as a hypersonic boost-glide
weapon.)
