The Department of Defense (DOD) is not using the full capabilities of its latest ultra high frequency (narrowband) military satellite communications system, the Mobile User Objective System (MUOS). MUOS provides secure communications less vulnerable to weather conditions or other potential impediments.
The full constellation of MUOS satellites has been on orbit for over 4 years, but DOD has not been able to use the system’s advanced capabilities—such as its 10-fold increase in communications capacity. A key reason is the military services’ delayed delivery of compatible radio terminals to users (see figure). DOD is funding and developing plans to accelerate procurement and delivery of these terminals.
