Remembering the LFK network

The well-known Arpanet was the first operational packet-switching network. Almost completely unknown is what we claim was the second operational packet-switching network, the LFK network - although, admittedly, it was a fairly minimal network. Work on the LFK network began in 1970, and it was installed and accepted in 1972. It was used as part of a logistics system relating to the Norwegian Air Force and the North Atlantic Treaty Organization (NATO). It was developed for the Norwegian Air Force Supply Command [Lufforsvarets Forsynings Kommando (LFK) in Norwegian] by two companies: Siemens Norway, which held the formal contract with LFK, and Norsk Data, which was a sub-contractor to Siemens but did most of the technical work.
