B-2 Squadrons

Abstract

The B-2 is currently undergoing modernization of avionics/communications systems, engines, armament systems, low observable components, core training system components, aircraft supportability improvements, and support equipment development. The Air Force will also study multiple structural, avionics, and engine modifications that could improve the performance of the aircraft and engines and reduce maintenance man-hours and the logistics footprint of the fleet. Focus of the studies will be on non-mission capable (maintenance) drivers, safety issues, and obsolescence issues through modernization of key components in the airframe, avionics, and engines resulting in improved aircraft availability of a high demand/low density fleet. The Adaptive Communication Suite (ACS) is a non-integrated system that provides SATCOM connectivity for Command and Control enroute to the target. A critical capability is the ability to receive Airborne Mission Transfer (AMT) and Beyond Line-of-Sight Situational Awareness. This effort includes improvements to the suite of B-2 ACS UHF communications system in order to become part of the baseline configuration, as well as modernization upgrades to conform to mandates. B-2 Armament upgrades integrate new and/or advanced weapons on the B-2 to attack a wider array of target sets, to include hardened, deeply buried targets, as well as destroy more targets per sortie. Integration of the Joint Air-to-Surface Missile Extended Range (JASSM-ER) weapon will further enhance the B-2s ability to attack and destroy high value target sets. The Low Observable Signature and Supportability Modifications (LOSSM) program supports the B-2 ability to penetrate anti-access combat environments, performing missions directed by the National Command Authority while ensuring aircrew survivability. The LOSSM program reduces low observable (LO) maintenance, and stabilizes and improves the combat-ready LO signature for the B-2 fleet. The B-2 Crash Survivable Memory Unit (CSMU) provides a more capable Flight Data Recorder (FDR) with increased capacity for storing Flight Information Data (FID) for recovery and use in the event of a mishap. The Radar Aided Targeting System (RATS) is planned to be a software only solution implemented in several B-2 system level Operational Flight Programs (OFPs) to provide radar-aided enhanced targeting capability through weapon hand-off navigational updates for guided nuclear weapons in a non-GPS environment. The B-2 Identification Friend or Foe (IFF) Mode 5/S modification program replaces the current IFF transponder with a new Mode 5 and Mode S capable transponder ensuring compliance with DoD Combat Identification mandates and global Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) requirements. Mode 5 is the DoD standard for secure combat identification and provides improved discrimination between closely spaced platforms, while reducing interference with civil air traffic control transponders, enabling the B-2 fleet to accomplish its anti-access and global strike mission. Mode 5 replaced the obsolete Mode 4 combat identification. Mode S is a civil air traffic control secondary surveillance radar process that allows selective interrogation of aircraft according to the unique 24-bit address. Mode S provides improved accuracy and altitude resolution and reduced interference from closely spaced aircraft through selective interrogation of assigned transponder addresses. The B-2 Training System upgrades include updates to training device hardware and components, simulation software, courseware and academic materials, instructional system design architectures, engineering drawings, and system documentation that is not driven by a funded aircraft modification. In FY 2020 and prior, the B-2 DMS-M effort is documented in PE 0605931F B-2 DMS, Project 653844 B-2 DMS; beginning in FY 2021, this effort is documented in PE 0101127F B-2 Squadrons, Project 675345 B-2 Modernization. The FY 2021 budget reflects a significant restructure of the B-2 DMS-M program that reduces the program scope to modernize the B-2 display functionality including the multi-function display units (MDUs) and Advanced Graphics Processor (AGP) of the baselined DMS-M program. The legacy display sub-system lacks the processing power to provide necessary situation awareness. In addition, the legacy MDUs are not supportable due to obsolescence and repair issues which will severely impact future aircraft availability. During B-2 DMS-M Displays development, the engineering baseline will be finalized and production representative kits will be purchased to support software development, platform integration, integrated development/operational test, pre-Milestone C production assessment, and B-2 nuclear certification testing. Diminishing manufacturing sources and materiel shortages for affected components will be addressed to protect the planned production program by mitigating unplanned part redesign and requalification risks. This effort will also require investment in systems engineering and software development to integrate the AGP into the B-2 current architecture that includes the legacy Threat Emitter Locator system and associated displays. The program will ensure the most efficient restructure minimizing rework from the baseline DMS-M program. This program element may include necessary civilian pay expenses required to manage, execute, and deliver B-2 weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605831F. This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year.
