5 Close Air Support Mission Close Air Support (CAS): air action by fixed-wing and rotarywing aircraft against hostile targets that are in close proximity to friendly forces, and requires detailed integration of each air mission with the fire and movement of those forces. Immediate CAS: occurs outside the planning cycle; may involve reallocating airborne aircraft. (U.S. Air Force photo by Tech. Sgt. Michael R. Holzworth) 5 Source: JP Close Air Support. (2009).

6 Close Air Support Mission Release Number: /17/ SOUTHWEST ASIA -- Coalition airpower integrated with Operation New Dawn partners in Iraq and the International Security Assistance Force in Afghanistan in the following operations September 16, according to Combined Air and Space Operations Center officials here. Close Air Support (CAS): air action by fixed-wing and rotarywing aircraft against hostile Air Operations in Afghanistan targets September that are 16, in 2010: close proximity to friendly Balocan, forces, RC-W and requires detailed integration of each air mission with the fire and movement of those forces. A U.S. Air Force B-1B aircrew, U.S. Navy F/A-18C pilots and U.S. Air Force A-10 Thunderbolt II pilots provided armed overwatch for friendly forces. F/A-18C pilots conducted a show of force. The B-1B aircrew release precision-guided munitions over an enemy target to deter enemy activity. A-10 pilots conducted a show of force, performed multiple strafing runs, and release multiple precision-guided munitions over multiple enemy positions to deter enemy activity, Joint terminal attack controllers deemed the engagements successful.

7 Systems Engineering Historical emphasis on system(s) Within the last years, rise in: 7 Family of Systems (FOS) Systems of Systems (SoS) Enterprise Architecture (EA) New emphasis on User capabilities Resolution of capability gaps Integration of systems End-to-end process Net-centric versus platform centric

8 System of Systems: set or arrangement of systems that results when independent and useful systems are integrated into a larger system that delivers unique capabilities Source: Defense Acquisition Guidebook. (2013). Retrieved from 8 Types of SoS - Directed: SoS objectives, management, funding, and authority; systems are subordinated to a SoS. - Acknowledged: SoS objectives, management, funding, and authority; however, systems retain their own management, funding, and authority in parallel with the SoS. - Collaborative: No top down objectives, management authority, responsibility, or funding at the SoS level; systems voluntarily work together to address shared or common interests. - Virtual: Like collaborative but systems do not know each other. Definition Example Systems Stakeholder Involvement Source: Office of the Deputy Under Secretary of Defense for Acquisition and Technology, Systems and Software Engineering. Systems Engineering Guide for Systems of Systems, Version 1.0. Washington, DC: ODUSD(A&T)SSE, System versus Collaborative SoS System Collaborative SoS A functionally, physically, and/or behaviorally related group of regularly interacting or interdependent elements; that group of elements forming a unified whole. (3) The component systems interact more or less voluntarily to fulfill agreed upon central purposes. The Internet is a collaborative system. The Internet Engineering Task Force works out standards but has no power to enforce them. The central players collectively decide how to provide or deny service, thereby providing some means of enforcing and maintaining standards. (5) May include communities of practice (COPs). Aegis Weapon System Digitally-Aided Close Air Support (DACAS); Digitally- Aided Fire Support (DAFS); Joint Personnel Recovery (JPR) Clearer set of stakeholders. Stakeholders committed to that system and play specific roles in the SE of the system.(11) Multiple levels of stakeholders. Often competing interests between individual system level, and the SoS level.(12) Governance (Management) Aligned PM and funding. Governance of the SE process is usually hierarchical. (11) Added levels of complexity due to management and funding for both SoS and systems; SoS has no control over constituent systems. Constituent system s program managers and systems engineers collaborative at the SoS level to influence system development that meets SoS needs. Governance of SoS SE process will necessarily take on a collaborative nature. (12) Operational Focus (Operational Environment) Designed and developed to meet operational objectives. Mission objectives are established on a structured requirements or capability development process along with defined concepts of operation and priorities for development.(13) Changes in systems to meet SoS requirements are based on agreements and collaboration. SoS needs are based on agreement and collaboration, not top-down authority from the SoS manager. (6) Acquisition Test & Evaluation Boundaries & Interfaces Performance & Behavior Aligned to ACAT Milestones, documented requirements, SE with a Systems Engineering Plan (SEP). Cross multiple system lifecycles, involving legacy systems, developmental systems, and technology insertion; collaboration on development of SoS requirements. Test and Evaluation of the [entire] system, or subsystems, is possible. Multiple systems at different stages of life cycle. Need to expand or redefine existing SE processes to accommodate unique considerations of individual systems to address the overall SoS needs.(13) Focuses on boundaries and interfaces for the single system. Focus on identifying contributing systems, gain their participation, and enable data flow, understanding, and functionality across the SoS based on participating systems concurrence. Performance of the system to meet specified performance objectives. Performance across the SoS that meets SoS user capability needs as agreed upon by the participating systems.

9 9 The Problem Set

10 The Problem Set Services [continue to] independently develop, field, and manage systems that are not interoperable in the Systems-of-Systems (SoS) environment 10 Stove-piped solutions, lack interoperability Require workarounds or extensive resources to mitigate interoperability shortfalls Problem set magnified when operating in the Coalition/multi-national environment Question: How does the SE community manage the SoS Engineering challenge to achieve an interoperable SoS? SoS challenge magnified by Systems at or approaching end of life-cycle Independently evolving legacy systems New and emerging systems COTs and proprietary systems/software Rate of technological change Asynchronous Life Cycles

11 Interoperability The interoperability problem is not new However, the pace of technology and the need to operate in a SoS environment have increased its impact Source: Military Readiness: Lingering Training and Equipment Issues Hamper Air Support of Ground Forces. (2003). Retrieved from 11

12 Interoperability Military services have not yet achieved DoD s goal The for ensuring interoperability that equipment problem acquired is not for close new air support missions is interoperable and cost-effective. However, the pace of technology and the need to operate in a SoS environment have increased its impact The digital systems are not interoperable across the services The lack of interoperability across the services reduces the equipment s effectiveness and limits its usefulness Source: Military Readiness: Lingering Training and Equipment Issues Hamper Air Support of Ground Forces.

13 Interoperability Interoperability: The ability of systems, units, or forces to provide data, information, materiel, and services to and accept the same from other systems, units, or forces AND to use the data, information, materiel, and services so exchanged to enable them to operate effectively together. Interoperability is more than just information exchange. It includes systems, processes, procedures, organizations and missions over the life cycle and must be balanced with information assurance. (DoDD ) Functional Interoperability: Also known as syntactic interoperability and technical interoperability. It implies coordination across organizational lines. The higher the number of stakeholders and their dependencies, the stronger the need to define common interface specifications. All parties must agree to implement a common profile or interface template (Sherif, 2009) Semantic Interoperability: focused on the consistent definition of data elements, ensuring consistency from system to system and application to application. Achieved through the development and use of standards for data and their definitions, minimizing interpretation errors.

27 Summary Challenges to SoSE are unique Disparate asynchronous lifecycles No single approach can solve these emerging problems, and thus no strategy is best for all projects (Gorod, Sauser, and Boardman, 2008) An Integrated Systems Engineering Development and Test & Evaluation Approach is valid for a collaborative SoS SoS approach must ensure synchronization of upgrades 27
