By 2005, the ROCN had removed several systems from the retired upgraded World War II-vintage destroyers and transferred them to seven of the "Chi Yang" class. These systems include SM-1MR Standard missile in box launchers, H-930 modular combat system, DA-08 air/surface search radar,and STIR-180 lighting radar. Each "Chi Yang"-class frigate has 10 SM-1 missiles installed in two forward twin box launchers on top of the helicopter hangar, and two triple box launchers installed between the stack and the hangar, pointing to port and starboard. "Chi Yang" (FFG-932) did not receive the upgrade.
