- The only ones I am aware of that were published,

- Not that obsolete... KH-11-8 and KH-11-9 are probably still operating,
- although we do now have at least two Advanced KH-11s on orbit as well.

- There are still certain inherent limits involved in imaging from
- an 800 km orbit. I believe that published KH-9 photo was supposed
- to have a resolution of around 1 ft. The current series can obviously
- do better than that...
