From son in law:

Yes, it's true. The main problem is Boeing's delay of their Block IIF
satellites. The AF is planning to buy 12 of them.

IIF was originally supposed to launch in 2000.... then 2004..... now late
2009 (optimistically).

It's not all Boeing's fault. The Gov't caused a lot of problems with
requirements creep, ill defined needs, and late design changes. You can
read the GAO report online. It' has all the gory detail.
