 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.
