Titan is no longer available; it was replaced by the
Delta IV Heavy which has a payload of 25 tons to low

with major upgrades payload might increase to 90 tons
or so. Atlas V Heavy could be used in the same way.

They may be out of production but at least one Titan's available. In
fact, one (T4b) is on pad 40 right now and is set to hoist a KH-12
variant up early next month, on or around the 9th I believe...
