Northrop will provide Flat Sequencing System (FSS) equipment to sort ‘flats’ – large envelopes, magazines, newspapers, catalogs and circulars – in the order in which they are delivered. The FSS, designed in collaboration with Postal Service engineers, sorts mail in delivery sequence at a rate of 16,500 pieces an hour, helping letter carriers start delivering mail earlier in the day.

Northrop said a pre-production FSS will be installed and tested in Dulles, Virginia, in August, and nationwide deployment of 100 systems will begin in summer, 2008.

The Flat Sequencing System will enable the Postal Service to provide more efficient service to our business customers, who rely on the mail to advertise, generate revenue, and get information into their customers’ hands as quickly as possible, said Walt O’Tormey, vice president of engineering.
