Sub Integrated Ant System
Abstract
The programs funded under the Submarine Integrated Antenna System project (0742) provide Nuclear Submarines (SSN), Ballistic Missile Submarines (SSBN) and Guided Missile Submarines (SSGN) with improved communications capabilities to support future Joint, Allied, and Naval operations. These efforts provide for the development and testing of submarine antennas designed to meet emerging submarine requirements: (a) Increased antenna performance while operating at speed and depth, (b) Increased stealth capability of existing and future antennas, (c) Antenna compatibility with new waveforms and transceiver equipment, (d) Increased capabilities of antennas and their interface to the External Communications System, and (e) Improved antenna design to reduce Total Ownership Cost. Specifically, this project funds research and development for submarine antennas including (1) Outboard Electronics (OE)-538/BRC Multi-Function Antenna, (2) OE-562 Submarine High Data Rate (SubHDR), (3) Advanced High Data Rate (AdvHDR) (4) Towed Buoy Antenna (TBA)(AN/BRR- 6/6B) (5) Antenna Improvements (6) Transition Engineering. The OE-538/BRC Multi-Function Antenna Program supports radio frequency communications from Very Low Frequency (VLF) to Ultra High Frequency (UHF) and provides Identification Friend and Foe (IFF), Global Positioning System (GPS), Mobile Users Objective System (MUOS), Tactical Data Link (TDL) via Link 16, and Iridium capabilities for all submarine classes across all submarine mission areas. The SubHDR program provides the submarine fleet with Extremely High Frequency (EHF) Low Data Rate (LDR), EHF Medium Data Rate (MDR), EHF Extended Data Rate (XDR), military Super High Frequency (SHF) , and enables reception of the Global Broadcast Service (GBS). The AdvHDR program develops communications methods that will improve communications and reduce the detectability of the submarines by the adversary utilizing the Optical Communications Project Arrangement with United Kingdom. The program also researches the Tactically Oriented Tech Insertion Mast (TOTIM), which decreases the size of the imaging sensors, increases modularity, sensor capabilities and supports mission specific payloads. The TBA AN/BRR-6/6B is installed on OHIO class SSBN submarines and a variant of AN/BRR-6 will be the TBA for COLUMBIA class. Each boat's towed communications buoys (2 each) support its primary mission to receive Emergency Action Messages (EAMs), a critical component of the Navy's Nuclear Command, Controls, and Communications (NC3). The Antenna Improvements project provides for Reliability, Maintainability and Availability (RMA) improvements and continued Preplanned Product Improvement (P3I) developments in support of current and future submarine antenna applications. The Transition Engineering program focuses on technology development and assessment to support Fourth Generation Undersea Warfare objectives. Principal objective will be to complete the Maritime Information System (MIS) Analysis of Alternatives (AoA). JUSTIFICATION FOR BUDGET ACTIVITY: FY19 Transition Engineering: Continue development of future undersea communications capabilities in support of Fourth Generation Undersea Warfare. FY19 Outboard Electronics (OE)-538: Complete OT on operational submarine in support of Full Rate Production (FRP). FY19 SubHDR: Continue development of Reliability Maintainability, and Availability, (RMA) components identified by research and analysis to maintain Ao throughout the life of the system. FY19 efforts are funded by prior year under-execution funds. FY19 AdvHDR: Continue Optical Communications Project Arrangement with United Kingdom to reduce the detectability of the submarines by the adversary. Continue research and analysis into communications (COMMS) payloads for the Tactically Oriented Technology Insertion Mast (TOTIM) to improve Low Probability of Detection (LPD). FY19 Towed Buoy Antenna (TBA)(AN/BRR-6/6B): Provides design specification, component development, system integration, and testing to improve system performance (measured by operational availability Ao) and reliability (measured by mean time between failures MTBF); of buoy shape, combined Radio Frequency (RF) and Depth Canisters, Antenna and Amplifier Improvements, and Inertial Measurement Unit (IMU). FY19 Antenna Improvements: Continue RMA and P3I improvements in support of current and future submarine antenna applications.
