An article on page 18 of the 3-12-01 Space News titled Navy to Improve Space Surveillance Sensors describes changes to Navspasur. It looks like by 2006, the UHF "space fence" will be changed to S-band and L band. I think those frequencies are about 2400 MHz and 1600 MHz respectively. The Navy plans to use the upgraded system for 20 to 30 years. No word on when UHF will be affected/eliminated. This is off topic so any discussions should take place elsewhere.
