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). With SV-1 and SV-2 launched and Initial Operational Capability (IOC) declared on 28 July 2015, the AEHF program has completed its development phase and is now addressing obsolescence, ground control enhancements, and operational resiliency issues via MILSATCOM Space Modernization Initiative. Develop and conduct systems engineering, integration and test of the Protected SATCOM Key Management Architecture (PKMA). Enable testing and integration of AEHF Local Key Management functionality within the Key Management Infrastructure (KMI) client with the AEHF system. Initiate PKMA integration activities with the AEHF prime contractor and the Enhanced Polar System (EPS) Control and Planning Segment (CAPS) contractor. FY 2017 was the last year of PKMA funds in Project 657103. MILSATCOM SMI efforts are funded in Project 657104, MILSATCOM Space Modernization Initiative (SMI). The Space Modernization Initiative (SMI) strategy is to evolve current and future Protected MILSATCOM (i.e., strategic, tactical, and polar) systems and develop a more affordable and resilient MILSATCOM enterprise capable of meeting near term and emerging MILSATCOM requirements. A significant thrust for this initiative is to demonstrate technologies and Concepts of Operations (CONOPS) that lead to a future Protected Anti-Jam Tactical SATCOM (PATS) capability that provides tactical-level MILSATCOM users protected, anti-jam satellite communications while operating in a contested environment. A Materiel Development Decision meeting was held in November 2016 to formally initiate the Protected Tactical Enterprise Service (PTES) program. Beginning in FY18, the PTES funds have been transferred from the MILSATCOM SMI project to PE 1206760F. The Protected SATCOM Services (PSCS) Analysis of Alternatives completed and the report was delivered to Congress on 18 April 2016. The AoA concluded that an aggregated satellite proved the most cost effective. Beginning in FY18, the Evolved AEHF funds have been transferred from the MILSATCOM SMI project to PE 1206855F, PSCS - Aggregated. The Evolved Strategic SATCOM (ESS) system being developed under PE 1206855F will include a strategic payload, the capability to integrate a hosted Protected Tactical Waveform (PTW) payload, and on-board resilience features. Beginning in FY18, the hosted PTW payload, a new start effort, will be developed under PE 1206761F, Protected Tactical Service (PTS). The PSCS AoA Follow-on For Resiliency (PAFR) study recommended an Enhanced Polar System (EPS)-like system for midterm (2023-2030) polar tactical coverage as a risk mitigation between EPS and a 2030+ solution. Beginning in FY18, MILSATCOM SMI funds have been transferred to the EPS recapitalization program, funded in PE 1206434F, Midterm Polar MILSATCOM System. This program is in Budget Activity 5, system Development and Demonstration (SDD) because it is conducting engineering and manufacturing development tasks aimed at meeting validated requirements prior to full-rate production.
