what are some facts about the kh 13 satellite?

Answer 1

The KH-13 is a potential successor to the KH-12 reconnaissance satellite. Only extremely limited information is available. It may or may not be the same project as 8X, later rechristened as EIS (Enhanced Imaging System). It is believed that a satellite launched as part of one of these programs was put into orbit in 1999 and others may have been launched afterward. What is described by some as the KH-13 may just be a variant of the KH-12. It is even possible that a distinct KH-12 does not exist, and the KH-13 is merely a late-model KH-11, a platform in use since 1976. (I excerpted this from Wilipedia}
