Introduction
• NAVSEA PHD DSD Mission
– Combat System Integration Testing (CSIT) – Battle Group Interoperability Testing (BGIT) – CEC West Coast Land Based Test Site (LBTS)

• Naval Combat Systems – Past & Present
– Review legacy systems when proprietary and MIL-STD ruled the day – Present current systems such as the CVN-76 SSDS MK2

• T&E Tools
– Hardware-In-The-Loop (HWIL) Simulation/Stimulation Systems – Data Collection and Analysis – Future initiatives

• Benefits of Open System Architectures (OSA)
– T&E Benefits – Tradeoffs

Our Mission

• Land-based reliability testing, integration, and certification of surface ship combat systems and computer networks both prior to initial operation and for in-service systems; • Design, development, and life cycle maintenance of standardized simulation systems; • Land-based facilities and services for the analysis of performance of in-service combat systems, subsystems, and equipment for afloat units; • Provide engineering and technical support for test and development of command and control systems Performs CSIT & BGIT for non-Aegis Surface Combatants

CSIT Description

Integration Phase
Low level subsystem tests designed to allow for rapid program fault isolation and correction.

• Interface Validation • Functional Operability

Demonstration Phase
Higher level of Combat System Testing that demonstrates that the integration of the Combat System performs IAW governing specification. Program change is not as fluid as in the previous phase.

• Multi Platform Interoperability Test • Single / Multiple Warfare • Functional Stress • Performance Test

• Stress and Endurance

Definition of an Open System
“A system that implements sufficient open standards for interfaces, services, and supporting formats to enable properly engineered components to be utilized across a wide range of systems with minimal changes, to interoperate with other components on local and remote systems, and to interact with users in a style that facilitates portability. An open system is characterized by the following: • well defined, widely used, preferably non-proprietary interfaces/protocols; • use of standards which are developed/adopted by recognized standards bodies or the commercial market place; • definition of all aspects of system interfaces to facilitate new or additional systems capabilities for a wide range of applications; and • explicit provision for expansion or upgrading through the incorporation of additional or higher performance elements with minimal impact on the system.”

CSIT Benefits from using COTS OSA
MIL-STD CSIT
Stress and Endurance 9% Interface Validation 27%

MIL-STD Interfaces Required each subcontractor to program and “re-invent” the required interface protocols, thus consuming test time to integrate and debug.

Performance Test 19%

Functional Stress 9% Single/ Multiple Warfare 10%

Multi Platform Interoperability 3%

Functional Operability 23%

Stress and Endurance 9% Performance Test 20%

Interface Validation 16%

Current CSIT with COTS OSA
Functional Operability 29%

Functional Stress Single/ Multiple 10% Warfare 10%

Multi Platform Interoperability 4%

Reduction in MIL-STD interfaces allows more CSIT time for higher level functionality testing in the application layer.

OSA T&E Tradeoffs

Pro
• Leverage commercial technology • Reduce internal R&D costs • Reduced interface VV&A costs • Plug-In-Play Philosophy • Option of using multiple vendors • Industry upgrades & patches • Repair costs are less • Access to collective knowledge from public and industry sources • Accommodates rapid-prototyping • Allows user to focus on their domain knowledge and subject area

Con
• Controlled by industrial product cycle • Shorter life cycle • Reduce in-house R&D expertise • Reliant on vendors VV&A processes • Plug-In-Play is not what they say • Too many standards to maintain • Reliance on vendor schedule for upgrades and patches • Increased security risk – common knowledge of standards • Unable to negotiate repair costs

Summary
• Evolutionary progression of Naval Combat Systems
– Reduction of proprietary equipment and MIL-STDs – Increased usage of open systems and standards

• Evolutionary progression of T&E Tools
– HWIL Sim/Stim environments lockstep with the combat systems – Data Collection and Analysis will continue to utilize OSA – Incorporating OSA middleware products

• OSA Benefits and Tradeoffs
– Scalability and affordability – Increased reliability of interfaces allows CSIT test events to focus on the complexity of the application layer

• Comments – “last nickels”
– CSIT test approach will evolve to support tech refresh of OSAs – T&E support of future combat systems will require the use of OSAs – Adoption of OSAs will require more government participation

“Jacta alea est” (the die is cast)
COTS OSA is here to stay - there’s no turning back!
