Fleet Tactical Development
Abstract
The Communication Automation Program is a continuing program that provides for automation and communications upgrades for fleet tactical users. It includes Battle Force Tactical Network (BFTN), Joint Aerial Layer Network-Maritime (JALN-M), High Frequency Over-the-horizon Robust Enterprise (HFORCE)and Automated Digital Network System (ADNS). The Battle Force Tactical Network (BFTN) on each surface, subsurface, air, or fixed US Navy platform utilizes previously installed/existing Line of Sight (LOS)/Extended Line of Sight (ELOS) radios (a.k.a. Radio Frequency (RF)) to create a secure gateway that inter-connects all users into a common RF Tactical Network (a.k.a. wireless). This network separately supports US-Only and NATO Allied/Coalition users' tactical data information exchanges on each platform (node) between and/or across separately dispersed RF Networks even if Satellite Communications (SATCOM) channels to shore are lost during an Assured Command and Control (C2) and Anti-Access/Area Denial (A2/AD) event. Joint Aerial Layer Network-Maritime (JALN-M), a system of systems (SoS) capability, is the Navy implementation of the JALN architecture which provides assured communications in any environment, especially Anti-Access/Area Denial (A2/AD). With disruption or loss of space tier communications, JALN-M establishes and/or restores connectivity with the High Capacity Backbone (HCB) tier, the Distribution Access Range Extension (DARE) tier, and the Transition tier in accordance with the JALN-M Initial Capabilities Document (ICD) and the JALN-M Analysis of Alternatives (AoA) Final Report. JALN-M is a robust, assured communications capability providing joint connectivity via the HCB and Navy platform connectivity via a pseudo satellite DARE capability. JALN-M will use the Extended Data Rate (XDR) waveform (Navy Multiband Terminal (NMT)) for intra-battle group DARE communications, a Common Data Link (CDL) waveform for the HCB cross-link capability, and will leverage enhanced Ultra High Frequency/High Frequency (UHF/HF) waveforms for coalition connectivity. Furthermore, a Positioning, Navigation, and Timing (PNT) capability will be developed and integrated into the JALN-M Pod, and will provide position and timing data to other Pod subsystems, both with and without Global Positioning System (GPS) connectivity. Because the Pod is being designed to operate in an A2/AD environment, the Pod HCB and XDR (NMT) subsystems need to be provided with PNT data in the absence of GPS, and the assured PNT subsystem will provide that data. The objective is to provide an alternative communication path in a denied environment, to support key information exchange requirement via ADNS. The current national focus on highly contested environments has highlighted the growing need for protected (anti-jam and low-probability of detection) communications. Projects such as JALN-M and High Frequency Over-the-horizon Robust Communications Enterprise (HFORCE) address capability gaps (network connectivity, network capacity, information and data sharing, network management) to enable assured communications in a satellite-denied environment. Although these projects will supplement and backup current capabilities, they may become the only communications paths available if satellite communications are completely denied. Navy is currently prototyping and demonstrating an aerial relay surrogate SATCOM communications capability under the JALN-M Project. The HFORCE Project will demonstrate resiliency and throughput enhancements via a hub-based HF communication architecture. HFORCE and JALN-M are very different approaches to solving the same problem: achieving assured communications in a satellite-denied environment. HFORCE will demonstrate a robust communications infrastructure in a SATCOM denied/restricted environment, particularly where beyond-line-of-sight (BLOS) connectivity is required with seemingly opposing requirements for long range, high data rates, and low probability of detection (LPD). HFORCE will address the need for protected and reliable BLOS C4I in SATCOM denied environments where opportunities exist to leverage shore infrastructure to address the SATCOM-denied gap. HFORCE prototype has the potential to augment current space-based BLOS systems, providing an alternative capability in satellite-denied environments that is affordable, reliable and secure. The HFORCE project will address this gap by leveraging large gain hub arrays to enhance performance of HF links. Large gain hubs in concert with multi-carrier waveforms and adaptive scheduling provide Mbps-class data rates to large platforms and orders of magnitude improvement in LPD performance over traditional methods. Small scale demonstrations have focused on performance of system at the physical layer. HFORCE will focus on a larger scale prototype hub to be used with legacy waveforms and legacy radios. Automated Digital Network System (ADNS) is the method by which Tactical Navy units transfer Internet Protocol (IP) data to Navy and Department of Defense communities on the Global Information Grid (GIG). ADNS is the gateway to tactical Wide Area Network (WAN) afloat for Internet Protocol network operations, supporting information dissemination and external connectivity. ADNS enables services and applications to interconnect to the Defense Information Systems Network (DISN) ashore via multiple Radio Frequency (RF) resources and pier connectivity. FY18 BFTN efforts will focus on the completion and documentation of Initial Operational Test & Evaluation (IOT&E). FY18 JALN-M efforts will focus on execution of the JALN-M demonstration flight tests which demonstrate Navy ship-to-ship/sub and ship/afloat-to-GIG communications via Airborne JALN-M Pod hosting Aerial Extended Data Rate (AXDR), High Capacity Backbone (HCB), and Assured PNT (Positioning, Navigation, and Timing) payloads. Results of the demonstration seeks to inform DoD and Navy leadership on the JALN way ahead (technical and programmatic risks) and of the viability of JALN-M as a future capability. FY18 HFORCE efforts will use results from JALN-M resiliency studies to inform development of HFORCE demonstration plan and cost analysis, procurement of commercial off the shelf (COTS) hardware for installation of prototype half-scale hub, and initiate HF protected waveform (HFPW) development including interoperability with legacy waveforms. Additional FY18 efforts include programmatic documentation development (e.g. cost estimate, Project Definition Document (PDD)). FY18 ADNS RDT&E investment will continue to support Interface Design Development (IDD) and integration with network applications, development of Line-Of-Sight (LOS) link, DISN integration, and development of Cipher-Text (CT) piers. ADNS development/integration will include addressing network management, intra and inter domain routing, Quality of Service (QoS), and Concept of Operations discussions. Continue Network-Based Cyber Security technology and virtualization to increase performance of the Navy's ADNS routing and transport architecture.
