Protected Tactical Enterprise Service (PTES)

Protected Tactical Enterprise Service (PTES) is a U.S. Space Force ground-system program intended to provide U.S. and allied tactical warfighters with worldwide, anti-jam satellite communications (SATCOM) using the Protected Tactical Waveform (PTW). Its low-probability-of-intercept communications address a growing threat of electronic-warfare attacks, particularly jamming of military SATCOM. PTES also supports added non-PTW SATCOM capacity for joint users. The FY 2027 request is in Space Force Research, Development, Test & Evaluation appropriation 3620F, Budget Activity 4, Advanced Component Development & Prototypes, which supports evaluation of integrated technologies and prototypes in realistic operating environments.

PTES comprises a Mission Management System (MMS), Key Management System (KMS), and Joint Hubs (JHs). A JH is unmanned computing and communications equipment at a SATCOM teleport; it processes PTW signals, connects to reach-back networks, and provides near-real-time networked control of connected terminals. Installing each hub entails site surveys, equipment such as modems and End Cryptographic Units, installation, and testing. User-terminal PTW modems are acquired separately by the military Services and international partners, making PTES infrastructure important to the Navy Wideband Anti-Jam Modem System, the Air Force-Army Anti-Jam Modem, and other users.

PTES began in June 2018 as a Middle Tier of Acquisition rapid prototype. Following a successful operational demonstration of PTW over Wideband Global SATCOM (WGS), it entered the Software Acquisition Pathway in May 2023. The Protected Tactical SATCOM Family of Systems is being introduced evolutionarily: PTW service begins on existing WGS satellites, then expands to commercial and purpose-built satellites. Boeing received the competitively awarded ground-system development contract in November 2018, with Raytheon developing End Cryptographic Units as a major subcontractor. The two FY 2027 research-and-development projects pursue WGS service and commercial-satellite expansion separately.

PTW Over WGS (PTWoW) Prototype Ground and Software Development funds software in the MMS, KMS, and JHs, along with hardware build, test, and installation at existing teleports. FY 2027 work continues initial-capability software development, corrects discrepancies found during evaluation, and advances the system toward full capability. It also implements system and cyber resilience and cryptographic standards needed in contested space and cyber environments. Initial Operational Capability is scheduled for the third quarter of FY 2027, using hubs at two separate WGS teleport sites, one WGS satellite, and operational MMS and KMS functions.

PTW Over WGS (PTWoW) System Development Baseline, Integration, and Test supports government-led end-to-end integration, developmental and operational testing, modem interoperability, and management of interfaces across the wider SATCOM enterprise. In FY 2027, teams will conduct qualification and regression testing, capability demonstrations, risk-reduction events, and cybersecurity assessments needed for authorization to operate. The 45th Test Squadron and STAR Delta 12's 4th Test and Evaluation Squadron perform developmental and operational test roles; Tobyhanna Army Depot handles PTW modem key loading and initialization. Work may also rapidly strengthen situational awareness and resilience against emerging threats. Full Operational Capability is scheduled for the third quarter of FY 2028, with hubs at at least eight teleport sites supporting ten WGS satellites.

PTW Over Commercial (PTWoC) mPOWER first adds non-PTW capacity for joint and allied warfighters through a partnership with Luxembourg, while establishing a route to protected service on the O3b mPOWER medium-Earth-orbit constellation. The effort procures, installs, and tests six teleports physical sites with SATCOM gateway terminals and supporting hardware through a NATO Support and Procurement Agency contract. After plans to acquire two teleports in FY 2026, FY 2027 work completes site preparation, surveys, installation, testing, and accreditation for the effort. Requested-year activity reflects higher integration demands associated with site infrastructure and installation.

PTW Over Commercial (PTWoC) PTES Upgrades adapts the WGS-developed system for PTW operations over mPOWER and commercial constellations in other orbital regimes. FY 2027 work continues requirements, architecture, interface, and acquisition-strategy development and calls for a contract to enhance PTES systems; it also supports additional JHs, demonstrations, integration, and threat-responsive resilience work. Commercial initial capability is scheduled in FY 2029, with PTW service through one hub and one commercial or international-partner satellite supported by MMS and KMS. Full capability is scheduled in FY 2031 and is intended to support service from nine locations across all equatorial longitudes, including highly inclined orbits needed for polar coverage.

Commercial expansion draws on coordination with Space Force, Army, research, commercial-SATCOM, and Defense Information Systems Agency organizations. An Astranis contract evaluates PTW applications for small geosynchronous satellites, while MIT Lincoln Laboratory is to demonstrate PTW over mPOWER satellites. The commercial acquisition approach will be informed by PTWoW execution; mPOWER bandwidth capacity is funded through a separate commercial SATCOM program. Together, these efforts aim to increase available capacity while extending protected communications across military, allied, and commercial space infrastructure.
