Armed Drones: Evolution as a Counterterrorism Tool

Armed drones (also commonly called Unmanned Aerial
Vehicles, or UAVs) are unmanned aircraft designed to
identify, surveil, and engage ground-based targets-ranging
from materiel to individuals-with kinetic weapons. The
United States has significantly increased its use of armed
drones to attack global counterterrorism targets since the
terrorist attacks of September 11, 2001 (9/11). Prior to 9/11,
the United States deployed unarmed drones at various
places around the world primarily to support surveillance
activities. Congress plays a continuing role in approving,
funding, and overseeing the use of UAVs.
Evolution of Armed Drone Usage
With the Curtiss NSC-2, the U.S. military first started using
remote-controlled aircraft in the 1930s-initially for
intelligence, surveillance, and reconnaissance (ISR)
missions, and later for deploying torpedoes and land-attack
bombs. The United States first employed drones in a
combat role in the course of the Vietnam War, including the
AQM-34 Firebee. The Firebee initially flew in the 1950s as
an aerial gunnery target drone, and then in the 1960s as an
intelligence-collection drone, and ultimately was modified
to deliver payloads in 2002. In September 2000, the United
States used an ISR drone over Afghanistan to find Osama
Bin Laden as he was being sought for his role in the 1998
terrorist attacks against the U.S. embassies in Kenya and
Tanzania. After the drone proved successful in ISR
operations-and in response to a need for additional lethal
tools after the attacks of 9/11-the U.S. military
increasingly outfitted drones with lethal payloads and
deployed them to a variety of geographic locations where
suspected terrorists resided.
While the specific number of global armed drones being
used for counterterrorism missions is not publicly available,
reporting suggests that the U.S. use of armed drones has
increased in the 20 years since they were first employed.
For example, from 2010 through 2020, the United States
undertook over 14,000 drone strikes in Afghanistan,
Pakistan, Somalia, and Yemen. Some security observers
have suggested that, as the United States has withdrawn
troops from many overseas locations and transitioned away
from manned counterterrorism missions, it is likely the use
of armed drones will increase.
Types of Targets: Surveillance or Kinetic Strikes
Drones perform a variety of national security missions for
the United States. Specific to how armed drones support
counterterrorism missions, the following are commonly
performed functions:
* Identifying High-Value Targets: conducting ISR to
identify terrorist leaders or those possessing special
skills deemed to be a significant threat to the United

States. Operators can use both armed and unarmed
drones for such a mission.
 Executing Signature Strikes: lethally targeting
unidentified individuals based on behaviors, patterns,
and locations often associated with terrorist
organizations.
 Targeting Equipment/Facilities: destroying buildings or
training areas used to house or support terrorist activity.

Possible Advantages of Using Armed Drones
Some national security professionals suggest there are
many positive aspects to the use of armed drones instead of
traditional manned aircraft, including the following:
 Safety: unmanned drones reduce the risk that a pilot
could be killed, injured, or captured should the platform
be damaged or destroyed.
 Precision: the ability of unmanned drones to get closer
to ground-based targets than traditional aircraft could
enables greater precision in targeting, thereby reducing
the risk of unintentional death and injury to
noncombatants and destruction of civilian property.
 Loitering: drones are able to linger and surveil targets
for longer than manned aircraft.
 Expense: the costs associated with acquiring,
maintaining, and operating unmanned drones are less
than that of manned aircrafts. In addition, the costs and
accompanying employment benefits associated with
training drone pilots are less than those for pilots of
manned aircraft.
