Description
Description — ID Systems
The Identification Systems program funds procurements and Engineering Change Proposals (ECPs) to address obsolescence and fact of life changes, installations, and certifications for the following Mark XII / Mark XIIA systems: AN/UPX-37, AN/UPX-41, AN/UPX-45 and AN/UPX-50 Digital Interrogators (DIs), AN/APX-118 and AN/APX-123 Common Digital Transponders (CXPs), AN/UPX-29 Interrogator System (comprised of Interrogator Set AN/UPX-24, OE-120/ UPX Antenna Group, and Mark XII or Mark XIIA equipment), AN/UPX-29 Modernization (UPneXt), AN/UPX-46 Interrogator System (comprised of CP-2819/UPX Processor and Mark XIIA equipment), Identification Friend or Foe (IFF) support equipment, and AN/UPX-34A Radar Track Discriminator System (RTDS). The Air Traffic Control Radar Beacon System, IFF, Mark XII/XIIA System (AIMS) is a DoD directed tri-service program designed to provide a universal air traffic control radar beacon system compatible with the National Airspace System program. It provides a secure identification system for military use on all combatant ships, selected auxiliaries, patrol craft, and selected Coast Guard ships by allowing all friendly forces to identify each other and neutral forces. The Mark XII/XIIA system supports several missions such as anti-air warfare, aerial bombardment, and naval attack. The OE-120/UPX antenna radiates Identification Friend or Foe (IFF) encoded Radio Frequency (RF) challenge pulses into space and receives the resultant IFF encoded RF transponder replies from space. Current surface ship OE-120()/UPX antenna systems will receive upgrade kits to improve system R&M. The upgrade kits will use open architecture and current technology that allows for continued production and future growth. An Engineering Change Proposal was awarded using RDT&E (PU 0676) funds for the Original Equipment Manufacturer to deliver an Engineering Design Model for shipboard test and evaluation in fiscal year 2018. Modernization of the DDG 1000 Zumwalt Class IFF Sensor Suite includes procurement activities, product improvements, and engineering changes for three Electronically Scanned Array (ESA) antennas, one UPX-42(C) Interrogator, and three RT-1912(C)/APX Transponders.
Justification
Justification — ID Systems
The FY 2026 request was reduced by $2.561 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative." The purpose of the AN/UPX-41(C) Digital Interrogators (DI) and AN/APX-123 Common Digital Transponder (CXP) program is to replace 20-25 year old hardware and software (HW/SW) with reliability and maintenance enhancements through the use of Commercial off the Shelf / Non Developmental Item COTS/NDI form/fit/function improvements. Incorporation of the Mark XIIA (Mode 5) capability occurred in FY08 and changes nomenclatures from AN/UPX-37 and AN/APX-118(V) to AN/UPX-41(C) and AN/APX-123(V), respectively. Incorporation of the Mark XIIA (Mode S) capability into the AN/UPX-41(C) DI is currently ongoing and will change the DI nomenclature from AN/UPX-41(C) to AN/UPX-45(C). AN/UPX-24(V) Field Changes will provide hardware updates to accommodate Mode 5 and Mode S functionality in fielded systems. AN/UPX-24(V) Mode S upgrades will provide improved shipboard combat identification by increasing the probability of identification of commercial and neutral aircraft. The AN/UPX-29(V) Interrogator System is deployed on high capability, state of the art surface platforms that require IFF operational performance beyond that provided by a standard Mark XII system for combat identification. Mark XIIA Mode 5 and Mode S provide improved secure cooperative combat identification throughout IFF. Mode 5 and Mode S are product improvements designed to be installed through engineering changes to digital Mark XII interrogators and transponders including AN/APX-118/123(V), AN/UPX-37/41(C), and AN/UPX-24(V). AN/UPX-29 Modernization (UPneXt) is required to address obsolescence with respect to the CP 1273/AN/UPX-24(V) Processor Controller, and associated system components and interfaces, with consideration for software architecture, hardware modernization (size, weight and power) network hardening and cyber security. AN/UPX-46 field changes will provide hardware updates to IFF Interrogator/Transponder Systems fielded on LCS 1 and LCS 2 ship class variants, and United States Coast Guard (USCG) ship classes which are currently equipped with AN/UPX-29A or AN/UPX-37 (with Target Data Extractor) interrogator system configurations and Mark XII transponder systems. The hardware updates will reduce unique IFF configurations by installing common hardware with Mark XIIA capability. AN/UPX-34A Radar Track Discriminator System (RTDS) field changes will provide hardware and software upgrades to fielded systems that will increase system performance and incorporate "other service" target libraries into the system's target database. The RTDS is a Non-Cooperative Target Recognition (NCTR) system. OE-120/UPX kits provide hardware and software upgrades to 40-year old fielded systems to improve system Reliability and Maintainability (R&M) by replacing obsolete assemblies and units. The OE-120/UPX kits use open architecture and current technology that allows for continued production and future growth. AN/UPX-36 replacement will install AN/UPX-46 Interrogator Systems on the twelve ships in the LSD 41 and LSD 49 ship classes. The replacement program will reduce unique IFF Interrogator Systems by installing common hardware configurations with Mark XIIA capability. The DDG 1000 Zumwalt Class IFF Sensor Suite requires modernization, through product improvements and engineering changes, in order to implement product support elements, mitigate obsolescence, and incorporate cyber resiliency.
