5. THE ADVANCED MULTIFUNCTION RF CONCEPT (AMRFC)
ONR initiated AMRF-C to determine the possibility of using wide-band arrays to meet multiple RF functions simultaneously
ONR used an open architecture approach to RF systems to allow multiple vendors to participate and pave the way for scalable, upgradable systems
The Multi Function Electronic Warfare Future Naval Capability (MFEW FNC) resulted from this effort
Demonstrated Functions
Comm: X-Band DSCS Satcom Link, Ku-Band Commercial Satcom Link, Ku TCDL
Navigation Radar
Electronic Warfare: Electronic Surveillance, Electronic Attack
Calibration

6. MFEW DEVELOPMENT GOALS
Meets key Electronic Surveillance capabilities: High Probability of Intercept (HPIO), Precision Direction Finding (PDF) and Specific Emitter Identification (SEI)
Capable of supporting additional RF functions
Supports other platform configurations, including back-fit
Technology transitions to fleet
Architecture that is modular, scalable and open

10. OPEN ARCHITECTURE SUCCESS
Separate contract let to DRS to develop a RFC SRU that met the open interfaces of the Northrop Grumman (NG) MFEW ADM architecture
DRS developed the SI-9161 RFC in parallel with their SI enabling ONR to leverage DRS investment in the SI-9155 for the NGC compatible SI-9161
The lessons learned on one configuration was leveraged to both
the Si-9161 development efforts, collaboration with ONR and NG was very valuable to the success of the SI-9155
The modular and forward thinking design of the two receivers enables the features between the SI-9161 and SI-9155 to effectively be interchangeable
The DRS RFC was used by Lockheed Martin (LM) during their RIMPAC testing
LM was able to integrate the SI-9161 in their ES architecture within a week
LM proposed the SI-9161 as part of SEWIP Block 2
LM is also using the SI-9161 SEWIP Block 1B HGHS

11. INDUSTRY SUPPORT
Ensure broad industry involvement in open architecture and standards development
Visits to and from industry
NDIA workshops (Industry and Navy participation)
Approximately 20 companies/40-50 individuals
8 November 2006 – Overview and feedback on IT INP
2 May Business case
28 June 2007 – Requirements and architecture
2 August Organization to define standards
Integrated Topside INP RFI responses received
Initiated industry co-led modular open RF architecture definition process in FY08

17. CHALLENGES, RISKS AND IMPLICATIONS
Confirmation that SRU/CSCI interfaces and specifications are accurate and sufficient for acquisition from alternate sources
Navy must provide protection of contractor intellectual property even as it demands compliance with MOSA
The price for lower total life cycle cost could mean higher initial acquisition cost
Standards selection can be risky and problematic requiring greater knowledge on part of the government
Interface standards evolve with time. Difficult to project the extent a given standard will endure or should be replaced
Standards-based architectures tend to change the focus of systems engineering from design to integration
Shorter commercial product lifetimes create logistical support challenges

18. potential operational performance benefits of oa based topside systems
The ability to adapt to evolving requirements and threats
Accelerating the transition from S&T into acquisition and deployment (make technology refresh an asset, not a liability)
Ensuring that the system will interoperate with all the systems with which it must interface without major modification of exiting components
Improving the extensibility for meeting new requirements and for introducing new capabilities

19. DIGITAL ARRAY RADAR PREMISE/GOALS
ONR’s government owned and integrated Open Architecture Digital Array Radar sunsets in FY12
Open Architecture test bed enables investigation of alternative solutions and risk reduction
Core government team with competency to design, build, and test next generation multi-mission radars (similar to SPQ-9, SPS-49, and APS-137 programs of the past)
Improves government ability to trade requirements throughout the development cycle
Competition at the subsystem level (vice TSPR) widens the pool of vendors able to compete
Constrain contractor costs by evaporation of sole source
Government develops and owns requirements and specifications
Government competitively selects subsystem vendors
The government has no business model impediments to the extensive adoption of relevant open commercial standards and specifications

20. OA RADAR SPECIFICATION (OARS)

21. CONCLUSIONS
ONR has a solid S&T foundation to support MOSA based systems of the future
OA is a real enabler for making systems more affordable
Leverage commercial investment;
Enhance access to cutting edge technologies
Enhance commonality and reuse across platforms
Enable increased competition
Industry is a willing partner and its involvement is essential in defining MOSA based architectures and standards
“Specifying modular architecture and open software standards is essential to allow spiral development of optimal systems design - constant evolution in capabilities should be expected.”
