In 1975, the Defense Communication Agency (DCA) took over operation of the ARPANET as it became an operational tool instead of a research project. In 1983, plans for a new generation of the Automatic Digital Network (Autodin II) were canceled. Instead, a separate network to connect military installations called MILNET was split off the ARPANET. The ARPANET would be used as an Internet backbone for researchers, but be slowly phased out. Both networks carried unclassified information, and were connected at a small number of points which would allow total separation in the event of an emergency. The DCA used the Defense Data Network (DDN) as the program name for these network programs.
As a large-scale, private internet, the DDN provided Internet Protocol connectivity across the United States and to US military bases abroad. Throughout the 1980s it expanded as a set of four parallel military networks, each at a different security level. These networks transitioned to become the NIPRNET, SIPRNET, and JWICS networks in the 1990s.
