The witness seminar ”NIBS: The Development of the Näcken Information Handling System, 1966–82” was held at the National Museum of Science and Technology in Stockholm on 14 January 2008 and was led by Nils Bruzelius. During the seminar, the development of the computerized command and control system of the Näcken-class submarines was discussed. A major feature of the system was the computerization of the calculation of target data, which made possible the automatic and simultaneous tracking and monitoring of ten different targets. Different aspects of this development were covered at the seminar, in particular the development of mathematical models for target calculation. The computing algorithm was formulated by researchers at FOA, and implemented in close cooperation with consultants from Teleplan. Moreover, the computerization of other systems related to the handling and controlling of the submarine, a task carried out by Kockums in Karlskrona, was discussed. The critical importance of digital computing in the magnetic mine protection system was underlined. In purchasing the computer system, separate technical specifications for hardware and computer software was formulated. The role of government intervention in the purchase of the central computer was discussed and debated. Finally, the technical and tactical testing of the submarine system was covered, with special emphasis on the computerized information handling systems. QC 20130422 |
