IBM helps to design and build the Automatic Sequence Controlled Calculator for Harvard University. It is used by Navy scientists to prepare ballistic tables.

An IBM Card Programmed Calculator (CPC), a card-operated system and the first digital computer used in the space program, is used in the development of the U.S. Army Redstone missile. The CPC adds figures at a rate of 2,174 a minute.

The Langley Research Center in Hampton, Va. -- then part of the National Advisory Committee for Aeronautics (a forerunner of NASA) -- begins studies of multistage, solid fuel rockets. Langley uses one of the IBM Card Programmed Calculators for its engineering calculations.

IBM announces the 650 Magnetic Drum Calculator, an intermediate-sized computer. The 650 is used in the design of the Jupiter C rocket.

IBM delivers one of its first 701 computers to Convair, the developer of the Atlas missile (which is later used in the Mercury program).

IBM introduces the 704 computer, which is applied in satellite tracking and missile design.

The U.S. Army's Computational Laboratory in the Guided Missile Division — which later becomes part of the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center — uses two IBM 650 computers to design the Jupiter C (Composite Reentry Test Vehicle), which consists of a modified Redstone missile and upper stages. The IBM 650 is a workhorse general purpose digital computer capable of performing 78,000 additions a minute.

The United States Navy announces that an IBM 704 computer will receive telemetry data from the unmanned Vanguard satellite to calculate and predict the orbit of the 20- inch sphere.

Priority development of the Jupiter missile is under way using an IBM 704, the first large-scale electronic computer used by the U.S. Army at Huntsville, Ala. Its magnetic tape system is capable of adding figures at a rate of 1,496,000 a minute.

Two IBM 704 computers are used to track the Soviet Union's Sputnik I, the world's first artificial satellite.

An IBM 705 computer at IBM's Vanguard Computing Center aids in the launch and tracking of Explorer I, the first non-Soviet Earth satellite. The satellite discloses evidence of Earth-circling radiation belts. The 705 data processing system is a powerful magnetic tape computer capable of 1,364,000 logical decisions a minute.

Vanguard I, a 3.2-pound satellite, reaches record heights.

An IBM 704 computer aids in the design and tracking of space vehicles.

IBM develops the ASC-15 guidance computer for the United States Air Force Titan II missile computer.

The United States accelerates its satellite launching program, including the first U.S. flight of monkeys (Able and Baker) into outer space. An IBM 709 data processing system is used in this effort. The 709 provides greatly increased computing power and is able to perform 2,496,000 logical decisions a minute.
