National Optical Astronomy Observatory shape the System and gain steady, state-of-the-art research capabilities of all apertures for open, merit based science. A future major capability for the US system is an Extremely Large Telescope with diameter up to 30 meters. Two private consortia are currently working on such projects which may be operational before the end of the decade. These are the Thirty Meter Telescope and Giant Magellan Telescope. NOAO is working with both projects in planning for potential future involvement of the broad US community through operational support funding by the NSF.
