Radar Operations Center (ROC) December 4, 2000

MEMORANDUM FOR:	Distribution
FROM:	W/OPS41- Tim Crum Chief, Operations Branch
SUBJECT:	WSR-88D Transition Power Maintenance System Program Status

This memo provides information on the resumption of the WSR-88D Transition Power Maintenance System (TPMS) Program. Recently, the Government and the TPMS prime contractor, Powerware, signed a contract modification that will restart the TPMS Program. The new agreement calls for the use of a static/battery-based transition power source (TPS). This technology and hardware has been successfully used and tested at five WSR-88D sites beginning in May 2000. Below are more details on how the program will proceed.

1. Schedule. Sites that have a rotary TPS system will be retrofit with the new static/battery-based equipment. Retrofitting existing TPMS sites will be completed prior to installing new sites. The installation of new TPMS shelters will begin in the fall of 2001. A schedule for the retrofit and new installations, by site, and details of the work to be performed during the retrofit will be released at a later date. The ROC and Vance AFB TPMS will be retrofit in December 2000. The shelter renovation work at Oklahoma City and Lubbock will be done in December 2000. The rest of the retrofit work will begin in January 2001 and continue through the fall of 2001. Below is the order for the first 20 TPMS renovations:

   1. Radar Operations Center, OK	11. Tallahassee, FL
   2. Vance AFB, OK	12. Tampa, FL
   3. Oklahoma City, OK	13. San Francisco, CA
   4. Lubbock, TX	14. Miami, FL
   5. Lake Charles, LA	15. San Joaquin, CA
   6. Houston/Galveston, TX	16. Key West, FL
   7. Corpus Christi, TX	17. Vandenberg AFB, CA
   8. Laughlin AFB, TX	18. Melbourne, FL
   9. Mobile, AL	19. Los Angeles, CA
   10. Eglin AFB, FL	20. Jacksonville, FL

2. Retrofit. The retrofits will have three phases. In the first phase, a staff member from the ROC, formerly known as the Operational Support Facility (OSF), will witness and sign off on the renovation of the shelter. In phase two, local site personnel are expected to provide access to the radar site as the contractor removes the rotary TPS and delivers the static TPS. In the third phase, a ROC staff member will witness the installation and checkout of the static TPS hardware and sign off on the acceptance form. The ROC will coordinate the retrofit and installations with sites in advance.

3. Maintenance/Training. The TPMS units have a 1-year warranty. The Air Force and NWS will announce specific maintenance and training plans as soon as they are coordinated, finalized, and scheduled.

4. Sites should leave their rotary TPS system off.

We will provide a program status update and schedule details after the January 2001 TPMS Program Management Review. We will send a second update after the retrofit program has begun.
