AN/SPN-46 Blk V Upgrade
Abstract
In accordance with the CNO approved 2022 PALC Roadmap update, the AN/SPN-46 Block V efforts have been updated to support fielding of critical system upgrades and align remaining efforts with the Brizo Upgrade. AN/SPN-46 Block V upgrades targeted aging/obsolete hardware and software components within the carrier landing system and replaces them with modern components to improve system performance in contested environments as well as system supportability. It consisted of a major operational software upgrade along with a refresh of numerous Commercial Off The Shelf (COTS) equipment sub-assemblies. Refresh sub-assemblies included: the radar's obsolete processor circuit card assemblies (CCAs), replaced with new generation CCAs; the radar's Real Time Operating System (RTOS), replaced with a current and supportable RTOS; and the radar's software, replaced with a reconfigured, optimized, modular format. These efforts were split into two phases to allow faster fielding of critical items. Phase 1 upgrades the radar's obsolete processor CCAs with new generation CCAs, inclusive of updated RTOS. Phase 2 efforts will be realigned to the SPN-XX Brizo Landing System efforts and include upgraded maintenance Local Area Network (LAN) hardware and software upgrades that optimize the software architecture as well as implement Risk Management Framework (RMF) Cyber Security controls. All of these upgrades are required to provide the fleet reliable, operational systems today and modular, modern, and maintainable systems that support the Air Wing of The Future.
