Advanced (EHF MILSATCOM (Space)
Abstract
Develop and acquire Advanced Extremely High Frequency (AEHF) Military Satellite Communications (MILSATCOM) satellites, mission control segment and cryptography for survivable, anti-jam, worldwide, secure communications for the strategic and tactical warfighters. AEHF satellites will replenish the existing EHF system (Milstar) providing much higher capacity and data rate (5x increase over Milstar II) capabilities. AEHF is a cooperative program that includes International Partners (Canada, the United Kingdom, and the Kingdom of the Netherlands). Space Vehicle-1 (SV-1) launched on 14 August 2010. SV-1 experienced a propulsion anomaly and was raised to its geostationary orbit using alternative orbit raising techniques. The original plan was to begin SV-1 on-orbit checkout in FY11, but in order to conserve fuel SV-1 arrived at its on-orbit checkout location on 24 October 2011. SV-2 has an April 2012 projected launch. With SV-1 launched and SV-2 scheduled to launch in April 2012, the AEHF program has nearly completed its development phase and is now addressing obsolescence, production continuity, supplier stability and industrial base issues. Future AEHF satellites will be procured using the Department of Defense (DoD) Efficient Space Procurement (ESP) concept, formerly known as Evolutionary Acquisition for Space Efficiency (EASE). The ESP concept is a procurement approach which seeks stable production and efficient sub-contractor product management through the block buy of two space vehicles at one time (please see Advanced EHF MILSATCOM P-40 Exhibit). In addition, the ESP concept includes use of RDT&E funding for a MILSATCOM Space Modernization Initiative (SMI), formerly known as the Capability and Affordability Insertion Program (CAIP), to fund engineering activities to reduce future production costs through manufacturing and producibility enhancements, improve capabilities through insertion of new technologies, and replace obsolete parts, crypto and materials. The SMI efforts will provide opportunities for competition to develop potential technology upgrades at the component and system level for future satellites of the current or any follow-on system. SMI efforts will include obsolescence management and mitigation efforts, technology maturation, qualification of new components, subsystem and component prototyping, architecture and system concept studies (to include hosted payloads), and pathfinder efforts to address MILSATCOM capability gaps identified in the Joint Space Communications Layer (JSCL) Initial Capabilities Document (ICD) and the forthcoming "Resilient Basis for SATCOM in Joint Operations" study. The FY13 request funds efforts such as SV-2 on-orbit test & operations support, incremental Mission Control Segment (MCS) development including ground mobile command and control, test/fielding and support, and studies/analyses as required. The FY13 request funds Interim Contractor Support (ICS). As SV-2 completes on-orbit test and incrementally developed MCS becomes operational, ICS sustains the AEHF system until Initial Operational Capability (IOC) declaration, projected late FY14. Additionally, the FY13 request funds preliminary design for the transition of the AEHF Key Management Architecture from the Electronic Key Management System (EKMS) to the Key Management Infrastructure (KMI). The EKMS and KMI are cryptography key management systems that enable transmission and communications security for the Protected SATCOM enterprise. The FY13 request also funds continued parts obsolescence studies and redesign, and risk reduction on MILSATCOM technologies. This program is in Budget Activity 4, Advanced Component Development and Prototypes, since it funds Advanced EHF technology validation and modeling.
