Nearly two decades ago, the Navy launched the first satellite of its Ultra High Frequency Follow-On (UFO) system into orbit to provide bandwidth and communications to troops and vehicles in the field. In less than a year, the service hopes to finally have the first satellite of a next-generation constellation with 10 times the capacity of the current system circling Earth. The Mobile User Objective System (MUOS) is a collection of five satellites — four active and one on-orbit spare — that will provide narrowband tactical communications in the ultra-high-frequency (UHF) band to troops in the field. After the Navy launches the first satellite in early 2012, the service will launch one per year until all five are on orbit. But that first launch has proved to be a moving target because integration and technical concerns have taken longer than expected to resolve. At one point, first on-orbit delivery of MUOS was scheduled for March 2010.
