This article in Wired from 2012 hints at supercomputers much more 
powerful than Jaguar at ORNL for cassified NSA use:

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.
