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). Conduct studies, analyses, and technology risk reduction activities to evolve protected MILSATCOM capabilities. First time integration and test challenges and flight hardware problems with Space Vehicle-1 (SV-1) delayed the projected launch to September 2010. These issues also impact SV-2 cost and schedule. SV-2 projected launch is now September 2011. A Nunn-McCurdy review, to include an OSD Cost Analysis Improvement Group (CAIG) Independent Cost Estimate (ICE), has completed and the program was certified on 29 December 2008. Added RDT&E funding in FY10-13 to fully fund SV-1 and SV-2 overruns and match the OSD CAIG cost estimate. The FY10 PB eliminated funding for the Transformational Satellite Communications System (TSAT) program. The FY11 PB funds the procurement of AEHF SV-5 and SV-6, and initiates an AEHF upgrade program (RDT&E) in FY12 for SV-7 and beyond. The FY11PB also funds efforts such as SV-1 on-orbit test and operations support, SV-2 integration, test and launch; technology needs forecasting; obsolescence and studies for future SVs; and incremental Mission Control Segment (MCS) including ground mobile command and control development, test/fielding and support. This program is in Budget Activity 4, Advanced Component Development and Prototypes, since it funds Advanced EHF technology validation and modeling.

Document Details

• Document Type: R2 Budgetary Justification
• Publication Date: Oct 01, 2011
• Source ID: 0603430F_4_3600_PB_2011
• Change Summary Explanation: $36.4.0M FY09 funds were reprogrammed in order to fund the program to the OSD Cost Analysis Improvement Group (CAIG) Independent Cost Estimate. With the termination of the TSAT program beginning in FY10, the FY09 Omnibus included the following for the AEHF program: 1) $35.0M to ensure the Air Force can leverage the TSAT technology investment and critical industrial expertise for the protected MILSATCOM capabilities required by strategic and tactical users worldwide. These technologies will be assessed for incorporation onto future AEHF satellites; and 2) $18.95M for the productization and qualification of radiation hardened electronics for DoD space systems. Funds are required to ensure the advancement of components, brought to the prototype stage by the S&T community, reach a maturity level that programs can use. The FY 2010 President's Budget submittal did not reflect FY 2011 through FY2015 funding. Therefore, explanation of changes between the two budget positions cannot be made in a relevant manner.
