The Hubble Space Telescope (HST) is basically a civilian version of the KH. And the National Reconnaissance Office (NRO) is launching one of those KH satellites every couple years. I bet the latest one (USA-290) has much better tech than Hubble and would make a good replacement for Hubble, with few modifications required. https://en.wikipedia.org/wiki/KH-11_Kennen https://en.wikipedia.org/wiki/KH-11_Kennen.
