More Info
The Air Force Second Space Operations Squadron (2 SOPS) indicates that IIF-8, SVN-69/PRN-03, will replace SVN-51 in the E plane slot 1. SVN-51 will be re-phased from E1 to an auxiliary node at E7 somewhere around SVN-54 currently on station at E4. SVN-38/PRN-08 will be taken out of the operational constellation prior to SVN-69 payload initialization and sent to Launch, Anomaly Resolution and Disposal Operations (LADO). PRN-08 will be assigned initially to SVN-49 and set to test. SVN-38 was launched on 05 November of 1997, successfully serving nearly 17 years, 9.5 years beyond its designed service life, due to the diligent efforts of the men and women of the U.S. Air Force. SVN-51 will remain in an auxiliary node once it completes its re-phase journey. Expect the SVN-51 re-phase to take about 6 months after the initial burn occurs.
