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.

 

 

What is the Information Domain?

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 commander’s 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.

 

What is Information Superiority?

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 one’s 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

 
What is a Network Centric Force?

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.)

 

Networking the Force: Extending the Information Domain

The networking of the force changes the topology of the warfighter’s 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.

 

An Emerging Conceptual Model

Intuitively, warfighters understand that a relationship exists between information and combat power.  However, capturing and quantifying this relationship has been, and continues to be, an analytical challenge of the first order.  Describing how the network can be leveraged to increase combat power corresponds to describing how an improved information position can be created and leveraged to increase combat power.  These two problems are the two sides of the same coin ¾ they are inextricably linked.

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

Physical Domain: The physical domain is the traditional domain of warfare.   It is domain where strike, protect and maneuver take place across the environments of ground, sea, air and space.g  Comparatively, the elements of this domain are the easiest to measure, and consequently, combat power has traditionally been measured primarily in this domain.  Two important metrics for measuring combat power in this domain, lethality and survivability, have been and continue to be cornerstones of military operations research.

Cognitive Domain: The cognitive domain is the domain of the mind of the warfighter and the supporting populous. This is the domain where battles and wars are won and lost.  This is the domain of intangibles: leadership, morale, unit cohesion, level of training and experience, situational awareness, and public opinion.  This is the domain where tactics, techniques and procedures reside. Much has been written about this domain, and key attributes of this domain have remained relatively constant since Sun Tzu wrote The Art of War.  The attributes of this domain are extremely difficult to measure, and each sub-domain (each individual mind) is unique.   Consequently, explicit treatment of this domain in analytic models of warfare is rare.   However, a methodology that begins to addresses key attributes and relationships of this domain has been proposed by Harmon in the context of “entropy based warfare.”h

 

Elements of Emerging Theory

At a high level of abstraction, warfare can be represented by mappings between the information domain, the cognitive domain, and the physical domain.  The application of a multi-domain approach can help analysts identify and characterize complex relationships between shared information, shared situational awareness, and increased combat power in specific mission areas.

 For example, consider the air superiority mission, and the operational situation associated with a four vs. four air-to-air engagement (portrayed in Figure 2).   To first order, the information needs of the opposing forces in this engagement are

approximately symmetric, since both forces require approximately the same information to perform the tasks associated with the engagement. Now consider two cases and their respective information positions.

Case I: Platform-Centric Operations

Fighter pilots in each aircraft operate with only voice      communications.

Case II: Network Centric Operations

Fighter pilots in each aircraft operate with voice         communications and a data network. 

With platform-centric operations (Figure 3), each pilot is able to develop situational awareness based on three types of

inputs: 1) direct observation of the physical domain; 2) indirect observation of the physical domain by onboard sensors, the results of which are portrayed via a human – information domain interface; and, 3) voice communications with other warfighters.   With network-centric operations (Figure 4), a fourth input is added, digital information that is exchanged from external sources, such as other fighter aircraft, or airborne surveillance and C2 aircraft, over a network.

 

 The situational awareness that the pilots in this 4 vs. 4 air-to-air engagement are capable of developing is a function of their respective information positions, which to first order can represented with the following variables:

         

i1,j (t) : Percentage of own force correctly typed and tracked

  within a sphere of radius R1 by force “j”

 

i2, j (t) : Percentage of adversary force correctly typed and      tracked within a sphere of radius R1 by force “j”

 

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 ).

 

 

Emerging Evidence for the Power of Network Centric Warfare

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.

 

A US Air Force Operational Special Project

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.

               

Fleet Battle Experiment Delta

          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 Army’s 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

 

 

Maneuver: Army Digitization and Experimentation

The US Army’s Task Force XXI Advanced Warfighting Experiment (AWE) and subsequent training operations with the digitized forces have highlighted the potential combat power that can be generated by a network-centric force.  The networking of the principal components of the ground force with the Tactical Internet enabled ground forces to operate more effectively in the information domain and develop a high level of shared battlespace awareness and to increase combat power.k

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

 

 

Network Centric Operations: Implications

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.

 

Conclusion

          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.
