ABSTRACT: The maximum data rates through store interfaces based on MIL-STD-1760 or other interface standards have been constrained by older data bus technology used in these interfaces. This has limited or precluded the ability to conduct efficient and timely transfers of certain data types such as large map or image files, target templates, digitized video, etc., between platforms and weapons, consequently limiting weapon effectiveness and/or operational flexibility in many instances. Recent incorporation of a high speed Fibre Channel based alternative data path into key store interface standards provides the potential to overcome such limitations. Further work is needed, however, to adapt existing Fibre Channel networking technology (including switches, terminals, etc.) to this application, considering the unique requirements of evolving weapons and manned/unmanned platforms. A preceding Phase I study analyzed relevant network functional requirements and implementation considerations, developed an adaptable Fibre Channel network architecture for satisfying the identified requirements, and assessed the state of technology needed to implement compliant networks. A recommendation was made to demonstrate and verify the developed network architecture in a manner that would also provide a test and verification environment for future prototype components and networks. This proposal describes a suggested Phase II effort to accomplish that recommendation. BENEFIT: The technology to be developed by this effort will facilitate improved mission effectiveness and operational flexibility for certain projected weapon types. It also has potential commercial application in sensor integration on air and ground platforms.
