What is Network Centric Warfare?
Network-centric operations are military operations
that are enabled by the networking of the force.a Network-centric
operations provide a force with access to a new, previously unreachable region
of the information domain. The ability to operate in this region provides
warfighters with a new type of information advantage, an advantage broadly
characterized by significantly improved capabilities for sharing and accessing
information. Network-centric warfare
enables warfighters to leverage this information advantage to dramatically
increase combat power through self-synchronization and other network-centric
operations.
Across a broad spectrum of mission areas, evidence
for the power of network-centric warfare is emerging from experiments and
exercises. Evidence collected to date supports a strong correlation between
information sharing, improved situational awareness, and significantly
increased combat power. A common theme
in this evidence is the critical role of modified (in some cases new) tactics,
techniques and procedures, in enabling warfighters to effectively leverage an
information advantage.
Network-centric operations focus on the tactical and
operational levels of warfare, but they impact all levels of military activity
from the tactical to the strategic. At the operational level, network-centric
operations provide commanders with the capability to generate precise
warfighting effects at an unprecedented operational tempo, creating conditions
for the rapid lock-out of adversary courses of action.
The
intent of this article is threefold: to provide the reader with a brief overview
of the underlying theory of network-centric warfare, to describe emerging
analytical constructs for characterizing network-centric operations, and to
highlight evidence that demonstrates the power of network-centric warfare.
The information domain is
the domain where information lives. It is the domain where information is
created, manipulated and shared. It is the domain that facilitates the
communication of information between warfighters. It is the domain where the command and control of modern military
forces is exercised, where commanders intent resides. Consequently, it is increasingly the
information domain that must be protected and defended to enable a force to generate
combat power in the face of offensive actions taken by an adversary. And, in
the all-important battle for information superiority, the information domain is
ground zero.
Information Superiority is a
condition
in the information domain. A condition that is created when one
competitor is able to establish a superior information position vis-à-vis an
adversary. Information Superiority
corresponds to an imbalance in ones favor in the information domain, to a
relative information advantage. The
concept of an information advantage is not new. Commanders have always sought ¾ and sometimes gained ¾ a decisive information advantage over their
adversaries. Indeed surprise, one of
the immutable principles of war, can be viewed as a type of information
advantage that one force is able to establish over another. A relative information advantage can:
·
Be
persistent or it can be transitory.
·
Exist
in some areas of the battlespace but not others.
·
Be
measured in the context of a task or set of tasks.
·
Be
created by taking actions to reduce our information needs and /or increase the
information needs of an adversary.
·
Be
achieved through the synergistic conduct of information operations, information
assurance, and information gain and exploitation.b
A network-centric force is
effectively linked or networked by an information infrastructure, or infostructure. A network-centric force has the capability to share and exchange
information among the geographically distributed elements of the force:
sensors, regardless of platform; shooters, regardless of service; and decision
makers and supporting organizations, regardless of location. In short, a network-centric force is an
interoperable force, a force that has global access to assured information
whenever and wherever needed.c (It is worth noting that a force with these
capabilities is not known to currently exist in any of the US Military services
or in the armed forces any our Allied or Coalition partners.)
The networking
of the force changes the topology of the warfighters information domain. It extends the existing domain and provides
access to a new region, to a new operational envelope. This new operational envelope corresponds to
the network-centric region of the information domain. Within this region reside information
constructs that are enabled by the network, constructs such as the common
operational picture and the common tactical picture. For example, Figure 1 portrays how the employment of data-links
provides access to this new operational envelope in the information domain.

Operating within the
network-centric region of the information domain allows warfighters to achieve
an information position that was previously not feasible ¾ to develop a type of information advantage
that was previously not possible. This somewhat abstract concept is at the core
of the underlying theory of network-centric warfare.
If warfighters are to
effectively operate in this new region of the information domain, it must be
mapped and explored diligently. It must
be explored with the same diligence and sense of purpose that test pilots
explored the operational envelope associated with supersonic flight.
Exploration
of this flight envelope by test pilots required mastery of the theory of
aerodynamics, and a new tool, which took the form of the Bell X-1. Similarly, exploration of the
network-centric region of the information domain requires mastery of theory,
appropriate analytical models, and tools in the form of high performance
experimental networks.
Continued
exploration of the relationships between information and combat power requires
both new analytic tools and new mental models. Ongoing activities to develop
metrics for the information domain are hacking through dense conceptual
underbrush in an attempt to identify a path that can be navigated. A conceptual model currently being developed
collaboratively by an Information Superiority Metrics Working Group is focused
on characterizing the relationships between shared information, shared
situational awareness, and the processes of collaboration and
synchronization. A key element of the
model is a focus on three domains: the physical domain, the cognitive domain, and
the information domain. d This conceptual model builds upon a
construct proposed initially by J.F.C. Fuller in 1917,e and refined in Measuring the Effects of Network-Centric Warfare.f

The
respective information positions for a network-centric force Blue force (j=1)
and a platform-centric Red Force (j=2) are portrayed in Figure 5. Since the information needs of these two
forces are approximately symmetric, the distance

between these two
points corresponds to a relative information advantage. If we assume that shared situational
awareness is proportional to information position, then it is not unreasonable
to assume that a force operating with voice and data links is able to develop a
higher level of shared situational awareness than a force operating only with
voice. Experimental evidence supports
the relationship between networking and increased shared situational awareness,
as well as strong correlation between shared situational awareness and
increased combat power.
Variables can be used to describe
the information exchanges between individual battlespace entities (e.g., ship,
aircraft, tanks, etc), as well as the various levels of shared situational
awareness that are enabled by these information exchanges.
A candidate set of variables
is presented below, for the information, cognitive, and physical domains.
Information Domain:
Ii(t)
= Ii (ii1(t), ii2(t),
, iij(t),
, iin(t))
A time varying, vector that describes the information position of
battlespace entity i. Vector Ii(t) consists of component
variables iij(t).
iij(t)
A time varying information variable, the value of which is potentially
influenced by several factors, including: the performance of operators, the
performance of sensors, and the characteristics and performance of the relevant
infostructure that links battlespace entities.
A(Ii(t),Ij(t))
A variable which describes the relative
distance in the information domain between the information positions of
battlespace entity i and battlespace entity j.
Cognitive Domain:
Ei(TTP):
A variable that describes the level of experience that warfighter i
(associated with battlespace entity i) has with a specific set of Tactics,
Techniques, and Procedures.
SAi(t):
A variable that describes the time varying level of situational awareness of
warfighter i. SAi(t) is
a function of [Ii(t), Ei(TTP)].
SSA(t):
A variable that describes the time varying level of Shared Situational
Awareness shared by N distinct warfighters.
Physical Domain:
IS(is1(t), is2(t),
, ij(t),
, isn(t)): A vector which describes the attributes and performance of an infostructure. The component variables ij(t)
are potentially time varying (e.g., is1(t) = voice, is2(t) = data ).
The increased
combat power that can be generated with network-centric operations has been
demonstrated in a broad range of mission areas in service and combined
experimentation, operational demonstrations and high-intensity conflict. A significant and growing body of data
provides evidence that following conditions are valid across a broad spectrum
of mission areas (nc = network-centric, pc = platform-centric).
Improved Information Position: Inc(t)
> Ipc(t)
Increased Shared Situational Awareness: SSAnc(t)
> SSApc(t)
Increased Operational Tempo: OPTEMPOnc > OPTEMPOpc
Increased Loss Exchange Ratio: Rnc
> Rpc
Evidence supporting these
conditions in the mission areas of counter air, Counter Special Operations
Forces (CSOF), and maneuver, is highlighted below.
Some of the most compelling
evidence for the power of network-centric operations developed to date is
provided by an Operational Special Project conducted by the US Air Force to
evaluate the military utility of tactical data links employed by F-15Cs. Data collected during over 12,000 sorties
and 19,000 flying hours demonstrated that the kill ratios for Joint Tactical
Information Distribution System (JTIDS) equipped aircraft over non-JTIDS
equipped adversaries were extremely high, increasing by over 2.5 x in offensive
and defensive counter air missions.i (Details are highlighted in Figure 6).

The
digitization and networking of the F-15Cs enabled digital information to be
shared between platforms, resulting in a significantly improved information
position for the JTIDS equipped F-15Cs.
It is clear that when compared to the information position of a fighters
operating with voice only, that the pilots flying F-15Cs with data-links were
able to establish a relative information advantage that translated to a
significantly higher level of shared situational awareness. The pilots were then able to exploit this
awareness advantage to significantly increase their operational effectiveness.
Recent proof of the enormous power of shared
information enabled by a network-centric force was provided by Fleet Battle
Experiment (FBE) Delta, conducted in October 1998 in conjunction with Exercise
Foal Eagle 98, an annual joint and combined exercise sponsored by Combined
Forces Command Korea. In this
experiment, the seemingly intractable problem of countering hundreds of North
Korean special operations boats (a Counter Special Operations Forces (CSOF)
mission) was dealt with on a timeline previously not thought possible. The application of network-centric concepts
enabled elements of the Armys 2nd Infantry Division, AH-64 Apache
helicopters, Air Force AC-130s, as well a range of Navy and Marine Corps units
to operate in the network-centric region of the information domain and to share
a common operational picture. This
resulted in a very high level of shared situational awareness that allowed
these forces to synchronize their efforts from the bottom up to achieve
dramatically increased combat power and to accomplish their mission in the half
the time required with traditional platform-centric operations.j
During the AWE, the improved
information position established by the Experimental Force (EXFOR) enabled it
to generate increased combat power, which was reflected in the metrics of
Operational Tempo (OPTEMPO), Lethality, and Survivability. Actual data collected during the AWE
reflected the following:l
OPTEMPO:
Plan
Development at the Division Level was reduced from 72 to 12 hours, resulting in
a 6-fold increase in OPTEMPO
Lethality:
Call
for Fire reduced from 3 min. vs. 0.5 min, which resulted in a 10-fold increase
in Lethality
OPTEMPO, Survivability, Lethality:
Deliberate Attack at the
company level 40 min. vs. 20 min.
Additionally, observations
from subsequent warfighting exercises and experiments with digitized and
networked ground forces have highlighted relationships between an improved
information position and increased combat power.
Value of Increased Shared Situational Awareness (SSA) at the
Unit Level: Increased SSA enabled by information sharing
over the network allows units at the platoon level to focus more of their
mental efforts on fighting the enemy and less on keeping track of their
location and the location of the rest of their unit. This increase in SSA has the potential, yet unmeasured; to result
in increased survivability and lethality. m
Value of Increased SSA in Increasing OPTEMPO:
Increases in SSA have allowed units at the platoon and company level to remain
in tactical march formations longer utilizing the speed of these formations to
increase the operational tempo of battle.
On several occasions, this increased operational tempo has allowed blue
forces to surprise opposition forces and gain a tactical advantage. Before the increase in situational
awareness enabled by information sharing, units had to move into attack
formation earlier to avoid surprise contact with the enemy and to conserve
combat power.n
Value of Increased SA in Maintaining Force Ratio: At the brigade and division
level, increased situational awareness has allowed to commanders to leave
forces in contact longer with the enemy.
Increased situational awareness of blue and red forces allows commanders
to develop a better real time understanding of the status and disposition of
their forces, of red forces, and force ratios.
This increased battlespace awareness gives them the confidence to allow
units to stay in contact longer with the enemy, resulting in increased combat
power.o
The ability to increase
combat power at the tactical level provides operational commanders with
increased flexibility to employ their forces to generate desired effects across
the spectrum of operations. Emerging
evidence highlights that network-centric warfare can provide commanders with an
improved capability for dictating the sequence of battle and the nature of
engagements, controlling force ratios and rates of closure, and rapidly
foreclosing enemy courses of action.
For example, consider the
operational situation associated with the CSOF mission. If the maritime component
commander can dramatically increase combat power in the CSOF mission, then the
ground component commander has the option of potentially reallocating ground
forces to other, more pressing mission areas, that he otherwise might need to
keep in reserve to deal with SOF leakers.
The networking of the force
is extending the information domain and creating conditions for the emergence
of network-centric operations. The source of the increased combat power
associated with network-centric warfare is non-intuitive. However, the application of emerging
conceptual models is providing a framework for identifying key relationships
between shared information, increased shared situational awareness, and
increased combat power. The evidence
of the power of network-centric warfare collected to date highlights the
importance of experimentation in developing and refining concepts and doctrine
for network-centric operations, as well as the benefits that can accrue to a
warfighting force that masters the concepts of network-centric warfare.
