POLAR ADJUNCT II (U)
(U) Polar Adjunct II is an upgrade of the Polar Adjunct I satellites and provides urgently required, protected communications services to U.S. Forces in the Northern Polar Region. The satellite primarily supports submarine connectivity with secondary support to naval surface forces. These communications satellites provide communications services to ground-fixed and transportable, airborne, submarine and ship terminals for global connectivity. The Polar Adjunct program provides a limited EHF capability at latitudes above 65 degrees North.

(U) Provides urgently required, protected communications services to U.S. Forces in the Northern Polar Region -- primarily supports submarine connectivity with secondary support to naval surface forces. Modified EHF communications payload from a UFO satellite placed on a classified host to provide coverage over 65 degrees North for 14 hours per day. Both an earth coverage and a 5 degree spot beam are available to support the one 4-channel and one 16-channel group capability. This is an interim solution until final capability is provided in accordance with the DoD MILSATCOM Architecture. The Air Force has committed to funding a third polar (hosted) package that will sustain 24 hour polar EHF capability into the 08-09 time frame.
User Impact (U):
(U) Without a Polar EHF capability, critical naval and SIOP users will be without protected communications above 65 degrees North.
