(IR) need this exportability guidance early to fully consider acquisition deci- sions


potential future sales.


In the past, when the U.S. exported com- munications equipment to our allies, it was often thought about in the form of a properly secured hardware platform (a radio). As SDRs continue to be devel- oped worldwide, our allies are beginning to request SDR waveform source code to put on their national SDRs.


Accordingly, JTNC technical analysis of DOD Waveform IR products includes exportability. Several JTNC reviews to date indicate the program documenta- tion needs to include consideration of waveform source


code export. Unfor-


tunately, in many cases, the documents and artifacts reviewed are vague and do

regarding SDR development and


not lend themselves to straightforward observations. To ensure that critical tech- nologies are not inadvertently exported, while enabling allied interoperability by making prudent export decisions, a comprehensive internal analysis of the waveform is needed to develop exportabil- ity positions and gain an understanding of any potential vulnerabilities. (See Fig- ure 1, Page 94.)


OPEN SYSTEMS Implementing open systems approaches requires persistence and effective dis- semination of collaboratively generated standards. Te culture shift to open sys- tems approaches is challenging, but the benefits of


implementing collectively


developed and agreed-upon standards include reusability and interoperabil- ity. Open systems and architectures are DOD’s preferred path to reusability,


interoperability and competition, as the April 2015 implementation directive for BBP 3.0 notes: “In accordance with DoDI 5000.02, PMs are responsible for applying open systems product designs wherever


approaches in feasible and


cost effective. Such approaches should be considered for enabling competition for upgrades, facilitating reuse across the joint force, easing technology insertion, and aiding adoption of incrementally upgraded software.”


Te JTNC DOD Waveform Standards Directorate is proactively engaging with government and industry entities on the evolution of the software commu- nications architecture and application program interfaces to enable alignment with industry standards and DOD acqui- sitions. To date, JTNC has 37 tactical radio standards registered in the DOD
