In February 2012, the ROC began construction of an antenna tower and associated facilities with the purpose of providing navigation assistance for aircraft landing. The tower had a planned height of approximately 7 to 8 metres, and was scheduled to be completed in April 2012, and fully functional after proper testing in September 2012. In July 2012, ROC authorities revealed a project which intended to extend the runway by 500 metres, which would allow the island to accommodate various kinds of military aircraft.
