The next space telescope will be the Nancy Grace Roman telescope which is a wide angle telescope so not an exact replacement.

The longer term goal is the Luvoir telescope but its not yet been approved and will probably require significant R&D like JWST.

Sure. I'm not talking about the timelines of existing plans for new telescopes. I'm comparing ROI vs:

- mission to reboost and service Hubble in various ways

- launching a new space telescope mission

It takes about fifteen years from concept studies to launch for a Hubble-class space telescope. I guess you could make it in ten if you just chose to replicate Hubble's instruments and if NRO had another spare Keyhole stashed somewhere...

The NRO donated two and parts for a third to NASA in 2012. One is apparently being used for the Roman Space Telescope, which would seem to leave another and a primary mirror of a third still unused.
