The results from the first track prompted the Air Force to build a second in 1948. Located just south of Rogers Lake, the track was capable of supersonic speeds. Its first project was the development of the SM-62 Snark cruise missile. This track was so successful that an extension was constructed, and on 13 May 1959, the full track was opened. After the Navy had conducted research on the UGM-27 Polaris ballistic missile, the track was used to develop ejection seats that could be used at supersonic speeds. Though this program was a success, a budgetary review concluded that the track was too expensive to maintain, and the track was decommissioned on 24 May 1963. Before it was closed, a trial run set a world speed record of before the test car broke up. After it closed, the rails were pulled up to help straighten Lancaster Boulevard.
