## What project 643726 buys

Protected Tactical Waveform (PTW) over Wideband Global Satellite (WGS) Initial Operational Capability (IOC) is expected in FY 2027. IOC will be achieved through Joint Hub (JH) installation at two WGS teleport sites at separate locations, which utilize one WGS satellite, in addition to nominal operations using the PTES Mission Management System (MMS) and Key Management System (KMS). Full Operational Capability (FOC) is projected for FY 2028, at which time PTES will provide worldwide PTW operations using JHs installed in at least eight different WGS teleport sites and utilizing ten WGS satellites. Research, Development, Test & Evaluation funding is required for continued architecture development, software development, and test and evaluation of PTES systems and segments. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 1206392SF and 1206398SF.

**R-3 lines of work:** Product Development; Test and Evaluation; Management Services.

## Named R-3 performers

| Performer | $M | Share of this project's FY2027 R-3 total |

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
