## What project 643733 buys

PTW over Commercial (PTWoC) Initial Operational Capability (IOC) is targeted for when Protected Tactical Waveform (PTW) operations are provided to users via a single Joint Hub over one commercial satellite, or International Partner (IP) satellite, including full Mission Management System (MMS) and Key Management System (KMS) support functions. PTWoC is expected to reach Full Operational Capability (FOC) after providing the ability to support geostationary, medium earth or highly inclined orbit PTW satellite communications from nine separate locations and for all equatorial longitudes. Highly inclined orbits are necessary in order to provide SATCOM coverage over the Earth's polar regions. Research, Development, Test & Evaluation funding is required for architecture development, acquisition strategy development, system requirements and system trades analysis, engineering, manufacturing, software development, and test and evaluation of PTES systems and segments. Initial PTWoC efforts are focused on providing additional, cost-effective SATCOM capacity to Joint and Allied warfighters via an international partnership with Luxembourg. Future efforts will focus on enabling Protected Tactical Waveform SATCOM operations over the O3b mPOWER Medium Earth Orbit constellation, as well as over commercial SATCOM constellations in other orbits. 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; Management Services.
