IBM launches a research project to develop an electronic device capable of calculating one million times a second.

July 1950
Byron L. Havens, who has been developing and testing components for an ultrafast, all-electronic successor to the SSEC, is ready to propose a large stored-program machine with 10 times the computing power of any computer then under construction.

August 1950
Havens's plans are discussed with members of the U.S. Naval Ordnance Laboratory, who express interest.

September 1950
Tentative specifications for the new machine are drawn up.

Sept. 19, 1950
An IBM committee including W. Wallace McDowell and Ralph L. Palmer recommends development of the machine to IBM president Thomas J. Watson, Jr.

September 1950
The Naval Ordnance Laboratory indicates its interest in procuring the machine.

October 1950
Work begins on the Naval Ordnance Research Calculator (NORC).

Assembly and testing of NORC begin at the Watson Laboratory at Columbia University in New York, N.Y.

December 2, 1954
The IBM Naval Ordnance Research Calculator (NORC) is formally demonstrated to the public at the Watson Laboratory and turned over to the Navy.

March 1955
The disassembled NORC is shipped in a fleet of 17 trucks to the Computation Laboratory at the Naval Proving Ground in Dahlgren, Va.

Summer 1955
NORC is reassembled and installed at the Naval Proving Ground by a team of 35 men (12 from IBM and 23 civilian Navy engineers, technicians, welders, carpenters and other mechanics).
