AN/SPN-46 Blk V Upgrade
Abstract
The AN/SPN-46 Block V upgrade targets aging and obsolete hardware and software components within the carrier landing system and replaces them with modernized components to improve system performance in contested environments and improve system supportability. Blk V consists of a major operational software upgrade along with a refresh of numerous Commercial Off The Shelf (COTS) equipment subassemblies. These changes improve reliability issues caused by outdated bus systems and IP based substructures, and provide an overall system hardening to mitigate external interference issues. Refresh subassemblies include replacing the radar's obsolete processor circuit card assemblies (CCAs) with new generation CCAs; upgrading the radar's Real Time Operating System (RTOS) with a current and supportable RTOS; and optimizing and reconfiguring the radar's software into a logical, modular format. This architecture redesign and optimization will increase modularity and operational efficiency and resolve cyber security related issues inherent with the legacy system. Additionally, hardware changes improve system reliability by modernizing those hardware components with less complex and more reliable solutions. Specifically this program upgrading the radar's top two hardware reliability degraders, the Radar Alignment Mast (RAM) pole and the TS-3098 test set. Rapid increase of CCA failures forced prioritization of imminent obsolescence issues; Block V efforts divided into two phases to allow faster fielding of critical items. Phase 1 upgraded the radar's obsolete processor CCAs with new generation CCAs, to include updating the radar's RTOS. Phase 2 upgrades the Maintenance Local Area Network (LAN) hardware and implements Risk Management Framework Cyber-Security controls. These upgrades are required to keep the system supportable/operational through 2040 to support legacy fleet aircraft precision landing requirements.
