AT&T Co has begun shipping 3B2 600s to government agencies following the Air Force’s award of the giant AFCAC 251 contract last October, potentially worth $4,500m over five years, but shipments will have to increase if the value is to be anything like that – so far AT&T has shipped only 120 systems in July, and Computer Systems News estimates that it need to ship around 350 units a month; AT&T says it was delayed by the appeal against the award by Honeywell Inc.
