    In 1973 the network expands to Hawaii and London as well as increasing its presence in the 48 contiguous states. Also, a transatlantic satellite link connected the Norwegian Seismic Array (NORSAR) to the ARPANET, making Norway the first country outside the US to be connected to the network.

    ARPANET declared "operational" and The Defense Communications Agency took control .

    In 1975, the ARPANET was declared "operational". The Defense Communications Agency took control since ARPA was intended to fund advanced research.[45] At about this time, the first ARPANET encryption devices were deployed to support classified traffic.
