became operational. \n\nThe excerpt below if from the Center for Cryptologic History's brochure titled\, 'Cry
ptology's Role in the Early Development of Computer Capabilities in the Un

d received the go-ahead on task order 13\, which required them to produce
a full-scale digital computer for the Navy. It resulted in a computer call
ed ATLAS\, which was delivered to the Nebraska Avenue location and put int
o operation in 1950. ATLAS was a formidable machine that used 24-bit words
and required over 2\,500 vacuum tubes. Two ATLAS 1 and two ATLAS II syste
ms (a more advanced 32-bit machine with two-address logic) were delivered
between 1950 and 1954\, and all were used on operational problems. As with
COLOSSUS\, these were not experiments\, they were full-scale\, reliable\,
operational machines that were used by cryptologists in their daily work.
ERA also built other systems and subsystems for the cryptologic community
. In particular\, they were pioneers in the development and use of magneti
c drum memories.'
