This article in Wired from 2012 hints at supercomputers much more
powerful than Jaguar at ORNL for cassified NSA use:
Meanwhile, over in Building 5300, the NSA succeeded in building an
even faster supercomputer. “They made a big breakthrough,” says
another former senior intelligence official, who helped oversee the
program. The NSA’s machine was likely similar to the unclassified
Jaguar, but it was much faster out of the gate, modified specifically
for cryptanalysis and targeted against one or more specific
algorithms, like the AES.

Since it's modified specifically for cryptanalysis, it might not meet
our definition of 'fastest', similar to the DE Shaw Anton system, which
can only do one thing, but do it extremely fast.
As a footnote, this Wired article came out over a year before Edward
Snowden's revelations, but covers many of the same NSA activities in his
initial revelations.
I think the two systems Killian referenced that are on the Top 500 list
are probably the 'low-hanging fruit' of the US classified systems. Since
there are much faster known systems in the world, letting the world know
they exist isn't that big a deal.

Those 2 seem already good candidates, although obviously not secret
since they're in the list:
* http://top500.org/system/178519
* http://top500.org/system/178445
They're #12 and #13, are labelled as "Government", provided by Cray,
seem to be totally identical, 3+PF, and vectorized-code friendly. What
else? :)
Cheers,
