The Naval Research Laboratory’s Tactical Satellite IV (TacSat-4) had recently launched a few days back; making it the 100th NRL built satellite that is launched into space. As a navy-led joint mission, the TacSat-4 provides “10 Ultra High Frequency channels and allows troops using existing radios to communicate on-the-move from obscured regions without the need for dangerous antenna positioning and pointing,” as reported by Carla Voorhees for Science.dodlive.mil.
The Operationally Responsive Space Office has funded the launch of the TacSat-4, along with the Office of Naval Research who sponsored the development. The project is managed by the Space Development and Test Directorate, and the spacecraft bus was crafted and built by NRL and Johns Hopkins University Applied Physics Laboratory.
Other major companies, offices and organizations essential for the build and launch of the craft include:
Air Force Research Laboratory, Johns Hopkins Laboratory APL, ATK Space, Ball Aerospace and Technologies, Boeing, Design Net Engineering, General Dynamics AIS, Microcosm, Microsat Systems Inc., Massachusetts Institute of Technology Lincoln Laboratory, Orbital Sciences, NRL, SMC, Space System Loral, and Raytheon.
