At sunrise on 25 July 1953 "New Jersey" was off the key port, rail and communications center of Hungnam, pounding coastal guns, bridges, a factory area, and oil storage tanks. She sailed north that afternoon, firing at rail lines and railroad tunnels as she made for Tanchon, where she launched a whaleboat in an attempt to spot a train known to run nightly along the coast. Her big guns were trained on two tunnels between which she hoped to catch the train, but in the darkness she could not see the results of her six-gun salvo.
