EHF SATCOM and Computer
Abstract
Originally the first of three increments to replace the Ultra High Frequency communication system with Extremely High Frequency (EHF) Satellite Communications System (SATCOM), B-2 EHF Increment 1 is a high-speed computing upgrade that provides upgraded flight management computer processors, increased data storage, re-hosted Flight Management Operational Flight Program, and a high bandwidth data bus to prevent degradation of existing capabilities resulting from future upgrades. Additionally, the new Integrated Processing Units and Disk Drive Unit architectures establish a high-speed fiber optic structure network while maintaining connectivity to legacy interfaces. This upgrade provides the required processing growth path to future B-2 upgrades such as, but not limited to, future communications capabilities, Defensive Management System Modernization, Flexible Strike, B61-12 and other weapons integration efforts. Four kits were developed with Research Development Test and Evaluation (RDT&E) funds for three aircraft installs, which includes two Force Development Evaluation installs and one Developmental/Operational Test aircraft install. The fourth development kit will be refurbished and utilized as a production install via procurement funding. Procurement funding will purchase the remaining 16 kits/installs for a total of 20 aircraft. Modification of the training system will be accomplished at the operational base and other locations as required. This effort also includes updating the aircrew and maintenance trainers and academics/courseware. The Production and Deployment phase acquisition strategy is based on a two lot buy: Low Rate Initial Production (LRIP) in FY2012 and Full Rate Production (FRP) in FY2013. Funds on the Support Equipment line are for upgrades to related support equipment. EHF Increment 2 was deferred in the FY13 President's Budget. The Air Force will pursue an alternative strategic communications method, the Common Very Low Frequency Receiver, to satisfy the immediate user need date. However, secure, survivable two-way communication remains a requirement for the warfighter. 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.
