The U.S. Army's Small Uncrewed Aircraft Systems


The U.S. Army is acquiring a family of small uncrewed
aircraft systems (sUAS) for ground maneuver elements at
the battalion level and below to provide real-time
reconnaissance, surveillance, and target acquisition (RSTA)
capabilities. For the past two decades, this role was largely
filled by the AeroVironment RQ-1 1 Raven (Figure 1). On
February 8, 2024, Secretary of the Army Christine
Wormuth  and General Randy George, Army Chief of Staff,
announced Army  plans to phase the RQ-11 Raven out of
service as part of a broader rebalance of the Army's
aviation investments. This product covers the Group 1 and
2 UAS-those  that weigh less than 55 pounds and fly at or
below 3,500 feet above ground level-intended to serve as
successors to the Army's legacy RSTA sUAS.

In 1988, the Department of Defense (DOD) Unmanned
Aerial Vehicle Joint Program Office (UAV JPO) published
its first Master Plan for uncrewed aircraft, which
established the requirements and acquisition strategy for
UAV  systems. The Master Plan recommended a close
range UAS for lower-level tactical units, one that could
be acquired in large numbers and at low cost. In the late
1990s and early 2000s, the Military Operations in Urban
Terrain Advanced Concept Technology Demonstration
(MOUT   ACTD),  an Army-led experimentation program,
showed how  a man-portable sUAS could provide ground
units with enhanced situational awareness and force
protection. The MOUT ACTD   led the Army and Special
Operations Command  (SOCOM)   to work with
AeroVironment  to develop in 2002 the fixed-wing, 4-pound
RQ-11  Raven, a smaller, more advanced version of the Gulf
War-era AeroVironment FQM-151   Pointer. The Army
introduced the RQ-1 1 in 2003 and, by 2010, fielded close to
4,000 Raven aircraft. The Marine Corps, SOCOM, and the
Air Force also adopted the Raven.

Beginning in the early 2010s, Army officials devised plans
for expanding the service's small UAS capabilities to
include a family of short-, medium-, and long-range sUAS
platforms. Under the Rucksack Portable UAS Increment II
Capability Production Document (RPUAS CPD), approved
in 2013, the Army provided a modified Raven and limited
quantities of the AeroVironment RQ-20 Puma to companies
and battalions, respectively, for medium- and long-range
RSTA  capabilities on an interim basis pending the
development of new platforms for these roles. Platoons,
meanwhile, would be equipped with a short-range drone,
the development of which the Army planned to begin later
in the decade. Separately, in 2017, the Army approved the
Soldier Borne Sensor (SBS) program to acquire miniature
drones for infantry squads. The Army selected the FLIR
Systems Black Hornet as the SBS and awarded FLIR a
contract for the first batch of SBS systems in May 2018.


The DOD  Defense Innovation Unit (DIU) issued a request
for information (RFI) in November 2018 for a quadcopter
drone to serve as a short-range sUAS; DIU partnered with
the Army on the platoon-level drone program the following
April. For medium- and long-range sUAS, the Army did
not begin to seek successors to the Raven and Puma until
the early 2020s.

In June 2023, the Army transitioned the RPUAS CPD
requirements to the Joint Small Uncrewed Aircraft Systems
Capability Development Document (J-sUAS CDD),
guidance that specifies key system and performance
attributes and an acquisition timeline for the Army's
planned family of RSTA sUAS. Similar to the Army's 2013
RPUAS   CPD, the J-sUAS CDD  describes Army plans to
field what the service now refers to as short-range
reconnaissance (SRR), medium-range reconnaissance
(MRR),  and long-range reconnaissance (LRR) UAS at the
levels of platoon, company, and battalion, respectively.
Additionally, the J-sUAS CDD contains three new
initiatives-first-person view (FPV) drones for squads and
platoons, tethered UAS for platoons, and a drone swarm
capability for companies-the requirements for all of which
remain in various stages of development. Including the
SBS, the J-sUAS architecture encompasses seven programs.

The requirements for the aircraft in the J-sUAS CDD
differentiate them from the Raven and Puma in several
ways. The Raven and Puma sUAS  feature a conventional
fixed-wing configuration, which potentially hampers their
usefulness in restrictive terrain, such as urban or forested
areas. With SRR, MRR, and LRR UAS,  the Army appears
to be prioritizing a vertical takeoff and landing (VTOL)
capability in the form of either multirotor or hybrid-VTOL
configurations. The Army's RFIs for future sUAS indicate
that the service plans to acquire aircraft that can deliver
