The definition of type 1 product is somewhat more stringent
(http://www.cnss.gov/Assets/pdf/cnssi_4009.pdf p. 64):

Type 1 product:

Cryptographic equipment, assembly or component classified or
certified by NSA for encrypting and decrypting classified and
sensitive national security information when appropriately keyed.
Developed using established NSA business processes and containing
NSA approved algorithms. Used to protect systems requiring the
most stringent protection mechanisms.

I'd never heard before that Skipjack was conceived to be used in type
1 products, i.e. that the algorithm was approved for anything above SBU.
I'd be interested to hear more.
