Roamy here. The TacSat-4 is scheduled to launch from the Kodiak Launch Complex in Alaska next month. This satellite will be launched on an Orbital Sciences Minotaur IV.
One of the articles I read about this said that there was a launch delay for TacSat-4 because of the Glory satellite launch failure back in March, but that was using a Taurus XL, not a Minotaur. Perhaps there’s some overlap in parts, or they were just being cautious. It will be good to have this capability in orbit.
TacSat-4 is a Navy-led joint mission which provides 10 Ultra High Frequency (UHF) channels and allows troops using existing radios to communicate on-the-move (COTM) from obscured regions without the need for dangerous antenna positioning and pointing…TacSat-4 provides flexible up and down channel assignments, which increase the ability to operate in busy radio-frequency environments and will cover the high latitudes and mountainous areas where users currently cannot access UHF satellite communications (SATCOMs).
I will definitely yield to the comm experts on how this truly helps, but more is better, right?
