P-1 NOMENCLATURE:
COMM ELECT MODS
Description (continued):
roles of aerospace control, force application, force enhancement, and force support. This PE supports both active duty and National Guard
requirements.
A. MOD #M00016, AN/TPS-75 Radar Shelter Replacement: No FY03 funding requested.
B. MOD #M00020, Antenna Bearing Redesign: No FY03 funding provided.
C. MOD # Miscellaneous Low Cost Mods: FY03 funding provides for the planned correction of deficiencies, functional obsolescence, high
failure anomalies and associated parts obsolescence due to diminishing manufacturing sources (DMS) within the CRC.
2. BALLISTIC MISSILE EARLY WARNING SYSTEM: The Ballistic Missile Early Warning System (BMEWS) primary mission is to
provide the US Commander in Chief, Space Command at Cheyenne Mountain Complex with timely, accurate and unambiguous tactical
warning/attack assessment data on intercontinental ballistic missiles penetrating the coverage area. BMEWS has the additional mission of
providing space vehicle surveillance, tracking, and identification to the space control centers. BMEWS consists of three operational sites: Site I
at Thule AB, Greenland; Site II at Clear AFS, AK; and Site III at RAF Fylingdales, UK.
BMEWS Service Life Extension Program (SLEP): The legacy Mission Critical Computer Resources (MCCR) at the BMEWS sites at Thule
AB, Greenland; Clear AFS, AK; and RAF Fylingdales, UK are obsolete and are becoming unsustainable. FY01/02 appropriations have funded
modified replacement units or re-engineered components for various computer peripherals that are most at risk of early unsupportability. FY03
funds provide reliability and maintainability modifications for the signal/data processing, conditioning, and presentation sub-systems that are
most at risk of becoming unsupportable. FY01-03 funding also procures interim supply support (ISS) and program management activities
(PMA). This modification is integral to the concurrent Space Mods modification of the two Sea Launched Ballistic Missile (SLBM) PAVE
PAWS early warning radars at Cape Cod, MA and Beale AFB, CA reference P-1 line # 61 Space Mods –Space.
3. CHEYENNE MOUNTAIN COMPLEX (CMC): The CMC provides real-time processing and display of missile warning and force
