Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2011 Appendix A-2III. IP Networking.Mandates and Milestones:Automated Digital Network System (ADNS) Increment III. (2016) The US Navy isconverting IP Wide Area Network (WAN) to Cipher Text (CT). All platforms connectingto the Navy WAN must be Increment III compliant by 2016.A. Tactical Airborne Network Local Area Network (LAN).1. Current capabilities.TTNT is an L-band anti-jam networking waveform well suited to support airbornecollaborative applications. It was successfully demonstrated in flight testing in 2005, andbeen used as a backbone network in multiple Joint Fleet Exercises (JFEXs) from 2004through 2009. It was designated as an initial increment of Joint Airborne Network -Tactical Edge (JAN-TE) requirements document in 2006, however the designation wassubsequently rescinded in 2009 and funding for integration into the MIDS-J terminalwas retracted. The ISR Task Force is using TTNT in an operationally relevantdemonstration to support the timely transport of ISR data to geographically separatedcommand structures. It provides a secure, ad hoc mesh network infrastructure.2. Advance Research and Technology Development.Secure Waveform Development & Protocols [TTNT Version 7.0] The Air Force,Navy, and JTRS Network Enterprise Domain (NED) have continued development of aTTNT JTRS SCA waveform which has been designated as version 7.0. The CriticalDesign Review (CDR) for this version was completed in 2008 and the JTRS NEDschedule for completion of the waveform is 4Q 2013. The TTNT Version 7.0 waveformwill provide the following improvements to version 6.0:Improved data efficiency through decreased message overhead requirementsImproved routing methods through destination and distance evaluationsLink Adaptation to allow spectrum reuseNew algorithms to reduce retransmissions and multicast messagingImproved Signal In Space performanceIncorporated JTRS SCAIncorporated NSA Unified Information Security Criteria (UISC) requirements3. Funded Enhancements and Potential Pursuits.Wideband Tactical Networking (TTNT). (2016) Currently there is no fundingprogrammed for development of a TTNT transceiver or integration of the waveform intoMIDS-J. The current version of the waveform, employed in legacy terminals, is version6.0. A limited number of EDM terminals are being used by the UCAS-N program todemonstrate carrier landing and aerial refueling capabilities for that platform. Platformintegration of a TTNT terminal currently presents the best near term opportunity toestablish a wideband tactical network capability for Naval Aviation.A-2 Information Exchange 17
