 New Jersey 's guns opened the first shore bombardment of her Korean career at Wonsan 20 May . During her two tours of duty in Korean waters , she was again and again to play the part of seaborne mobile artillery . In direct support to United Nations troops ; or in preparation for ground actions , in interdicting Communist supply and communication routes , or in destroying supplies and troop positions , New Jersey used her 16 inch guns to fire far beyond the capacity of land artillery , moved rapidly and free from major attack from one target to another , and at the same time could be immediately available to guard aircraft carriers should they require her protection . It was on this first such mission at Wonsan that she received her only combat casualties of the Korean War . One of her men was killed and two severely wounded when she took a hit from a shore battery on her number one turret and received a near miss aft to port .
