Established in 1954. The Army command post D-15DC evolved with the NIKE System housing a FSG-1 (Missile Master) and later a FSQ-51 (Missile Mentor) acquisition, launch and guidance systems. The building that housed the Army computer equipment and command post came to be known as the Missile Master Blockhouse. The Army deactivated the Selfridge D-15DC site in June 1974 and the collocated USAF Radar site was also deactivated that same year on 1 Sep 1974. The command post building survived until 2005 when it was demolished.

Besides the FSQ-51 and FSG-1 computer equipment, the Army also maintained two FPS-6 height-finder radars. These height-finders were in addition to the two USAF height-finders. Search radar data from the USAF FPS-35 was shared by the Army and USAF computer systems and fed to the SAGE Direction Center DC-06. The SAGE Direction Center would feed track assignments back to the Army command post for missile intercepts.

After the abandonment of the Missile Master Blockhouse (Building 1050) in 1974, the blockhouse was renovated and put into use as a military air traffic control RAPCON facility that operated into the 1990s.
