On 21 March, the destroyer resumed station off Vietnam. This time, however, off the coast of North Vietnam. Instead of supporting American and South Vietnamese troops directly through shore bombardments, she did so by interdicting enemy logistical efforts in Operation Sea Dragon. Though primarily directed at the enemy's water-borne logistics, "Sea Dragon" also struck wherever possible at the enemy's overland supply lines. During her 26 days on station engaged in "Sea Dragon" operations, "Turner Joy" fired on a number of shore targets in addition to an even larger number of enemy waterborne logistics craft. On 7 April, while firing on some enemy craft beached near Cap Mui Ron, the destroyer came under the fire of a North Vietnamese shore battery. During that exchange, she suffered a direct hit on the fantail and a near-miss air burst above the forward mast. The hit astern penetrated the deck to the supply office, damaging records therein as well as pipes and cables in the overhead. Several rounds of 5 inch VT fragmentation projectiles in mount 53 ammunition stowage area also suffered damage and had to be discarded. Shrapnel from near misses wounded a member of "Turner Joy"'s repair party and peppered her bow while the air burst above the forward mast put her air-search radar out of service except for its IFF aspect. The damage, however, was not severe enough to curtail her tour of duty; and she remained on station until relieved by on 16 April.
