There are two more Blackbirds (pause for reverence) parked at the north end

Speaking of Blackbirds, did you know that two of them are unaccounted
for? The Roadrunners (a fraternity of former Blackbird pilots,
crewmembers, workers, etc.) have done an excellent job of listing where
each SR-71 ever built has ended up -- and come up two short.

Rumor has it that they're still flying...but no one knows, for sure.

Given that we have no equivalent replacement I would expect them to be
used.

Of course there's an equivalent replacement - they're orbiting several
hundreds of kilometers up and go by names like KH-12, Improved Chrystal,
Indigo, LaCrosse, Vega, and likely a half a dozen other names still
classified.

Similiar, not equivalent.

The SR-71 was retired because there's no need for its capabilities any
longer. Everything the SR-71 could do can now be done cheaper and better
(and more safely) by satellites.

The Predator does provide another similar function currently. It
covers most of the gaps left by satellites.
