兵装は、
the vessel will be fitted with a BAE Systems 5 inch Mark 45 naval gun system, 16x Mk41 VLS cells for surface to air missiles, 8x anti-ship missiles (likely XSSM because of the shape of the cannisters),
a Raytheon SeaRAM short range missile launcher on top of the helicopter hangar, torpedo and decoy launchers.
