The U.S. Navy has authorized Boeing Satellite Systems Inc. (BSS) to begin production of the 11th in a series of UHF Follow-On (UFO) satellites, which provide global communications for the armed forces. BSS is a unit of Boeing. The agreement amends an existing $1.9 billion contract under which BSS has built and launched 10 UFO satellites. The satellite will be launched in 2003. The Navy began replacing and upgrading its ultra-high frequency (UHF) satellite communications network during the 1990s with a constellation of Boeing 601 spacecraft known as the UHF Follow-On (UFO) series. In 1999, the Navy's Space and Naval Warfare Systems Command granted BSS initial funding for long-lead parts procurement and related activities on UFO F-11. With this authorization to proceed with F-11's construction, the Navy is moving to sustain the UFO constellation into the latter part of this decade. "Over the life of this highly successful program, the UHF Follow-On payloads have evolved to meet the customer's changing needs, while being contained within the same basic Boeing 601 platform. This building-block approach allowed us to add valuable enhancements to the satellite payloads without a break in production," said Tig H. Krekel, president of Boeing Satellite Systems Inc. "We take great pride in our role on this program because the UHF mobile service is the backbone of military communications today, supporting warfighters on land, at sea and in the air." UFO F-11 will use the Boeing 601 bus, like the previous UFO satellites. It will carry a UHF (ultra-high frequency) payload for narrowband two-way battlefield connectivity and an EHF payload. The high-capacity EHF subsystem provides enhanced antijam telemetry, command, broadcast and fleet interconnectivity communications, using advanced signal processing techniques. The most recent UFO satellites -- F-8, F-9 and F-10 -- also carry a high-capacity global broadcast service (GBS) payload, which uses commercial-like direct broadcast satellite technology to provide critical information to U.S. and allied forces. The UFO constellation provides the Department of Defense (DoD) with communication services that range from mobile communications to intelligence dissemination and quality-of-life programming.
