The SM-65 Atlas was the first operational intercontinental ballistic missile (ICBM) developed by the United States and the first member of the Atlas rocket family. It was built for the U.S. Air Force by the Convair Division of General Dynamics at an assembly plant located in Kearny Mesa , San Diego .
1957 - Launch of the first ICBM, the USSR's R-7 (8K71), known to NATO as the SS-6 Sapwood. 1957 - The USSR launches Sputnik 1, the first artificial satellite. 1958 - The U.S. launches Explorer 1, the first American artificial satellite, on a Jupiter-C rocket. 1958 - US launches their first ICBM, the Atlas-B (the Atlas-A was a test article only).
Some of the earliest computers were military computers. Military requirements for portability and ruggedness led to some of the earliest transistorized computers, such as the 1958 AN/USQ-17, the 1959 AN/MYK-1 (), the 1960 M18 FADAC, and the 1962 D-17B; the earliest integrated-circuit based computer, the 1964 D-37C; as well as one of the earliest laptop computers, the 1982 Grid Compass.
The first computer to use magnetic tape. EDVAC could have new programs loaded from the tape. Proposed by John von Neumann, it was installed at the Institute for Advance Study, Princeton University, Princeton, New Jersey, US. 1951: Australia CSIRAC used to play music – the first time a computer was used as a musical instrument. 1951: US
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
The D-17B (D17B) computer was used in the Minuteman I NS-1OQ missile guidance system. The complete guidance system contained a D-17B computer, the associated stable platform, and power supplies . The D-17B weighed approximately 62 pounds (28 kg), contained 1,521 transistors , 6,282 diodes , 1,116 capacitors , and 5094 resistors .
1958 – August – The PGM-17 Thor intermediate-range ballistic missile, the U.S. Air Force's first ballistic missile, is declared operational and begins deployment in the United Kingdom through Project Emily. [17] 1958 – November – The United States and the Soviet Union observe a nuclear-testing moratorium. [40]
Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields. The second structured method for documenting process flow, the "flow process chart", was invented by Frank Gilbreth to members of ASME in 1921 as the presentation "Process Charts—First Steps in Finding the One Best Way".
