DSB report on milspace, FIA

I had a chance to drop a question into Vernon Loeb's online session
today, and he answered thus:

Harlingen, Tex.:
Any comments about the recent Defense Science Board report on
acquisition of national security space systems?

It seems to confirm, among other things, that the Future Imagery
Architecture (FIA) is having considerable problems. The present
imagers, particularly the three LACROSSE/ONYX radar satellites,
are getting somewhat long in the tooth. So the possibility seems
real that the US faces a considerable period of decreased
capability in the important area of all-weather, day/night
satellite imagery.

Vernon Loeb:
The problems with Future Imagery Architecture is one of the great
failures of the intelligence community over the past decade. The
cost overrruns for righting the program to build the nation's
next generation spy satellites are enormous -- I'm told perhaps
the largest ever in the history of defense programs. And the
implications--that America could find itself without a space
imagining capability, a capability it has held a virtual global
monpoly on for 50 years--are even greater still. But because this
program is secret, the American people will basically never know
anything about it, except in its broadest outlines. Unlike the
911 attacks, this is one people really should be held accountable
for.

That "perhaps the largest [cost overrun] ever in the history of
defense programs" is pretty impressive. Anybody know what the
present record-holder is?
