Ships assigned to Sea Dragon were normally split into a northern and southern unit (although during 1967 up to four units were operating at any time), with each unit made up of two to three ships. However, the Australian government forbade RAN vessels from operating in the northern area.
  • Naval gunfire support operations to assist ground forces, particularly the United States Marine Corps units operating closest to the North Vietnam border. Seven ships were usually stationed on the 'gunline', and attacks fell into two categories: 'unspotted' shelling of areas where North Vietnamese or Viet Cong forces and facilities were known or believed to be, and 'spotted' fire missions in direct support of ground troops. During these operations, Hobart operated under the callsign "Royal Purple".

Although RAN ships on deployment were expected to fulfill all duties of an equivalent American destroyer, they were forbidden by the Australian government from operating outside the Vietnam theatre on unrelated Seventh Fleet duties (such as the Taiwan Patrol Force, guard ship duties at Hong Kong, or the Space Recovery Program). After the invasion of Cambodia in 1970, RAN ships were also prohibited from entering Cambodian waters.

The deployment of Hobart in March 1967 began a pattern of six-month deployments for RAN destroyers, with a constant RAN presence with the Seventh Fleet.

First deployment

On 15 March 1967, Hobart arrived at Subic to join the Seventh Fleet. After a comprehensive familiarisation period, Hobart replaced on 31 March, taking over the US destroyer's gunfire support duties. By 04:45 the next morning, the Australian ship had already fired 100 rounds. On 3 April, the forward 5-inch gun mount became unservicable, a state which remained for four-and-a-half-days. Hobart remained on the gunline until 15 April, during which she fired 1,651 shells. She was then rotated to Sea Dragon operations. The destroyer was fired on by shore batteries

 several times, and on one occasion took minor shrapnel damage. Several explosions in 5-inch/54 gun mounts during the later weeks of April saw all equipped destroyers (including Hobart) reassigned to other duties while investigations into the cause (believed to be a bad batch of ammunition) were explored. Hobart was attached to the carrier escort group for on 23 April. On 29 April, the destroyer sailed to Subic, underwent self-maintenance, then returned to Sea Dragon operations. Over the next week, Hobart and cooperated on the interdiction of coastal shipping during a period of heavy activity; previous successes saw the North Vietnamese begin to increase retaliation with coastal artillery in an attempt to dissuade American operations. Apart from a brief stint on the gunline, Hobart remained assigned to Sea Dragon until 26 May, when sailed to Subic for maintenance, with both 5-inch gun barrels replaced.

al conditions, the Australian warship returned to the gunline on 18 June. During this period, the destroyer was also called on to escort the amphibious warfare ships involved in the Beacon Torch landings. After mid-June, the number of fire missions undertaken by Hobart dropped because of a need to conserve 5-inch/54 ammunition across the Seventh Fleet, and the fact that Marines in the area had successfully established their own artillery units in the area and were less reliant on naval gunfire. On 23 June, Hobart rotated to Sea Dragon. A reduction in the number of seaborne infiltration attempts and the increasing availability of spotter aircraft meant that most gunfire missions were against inland targets like truck convoys. On 10 July, the destroyer left the operational area and sailed to Subic via Hong Kong, and underwent self-maintenance. This was completed on 24 July, and Hobart sailed for the operational area. The ship was double tasked to the escort group and Sea Dragon operations; three destroyers were required to escort the carrier at any time, with any additional ships operating on Sea Dragon duties.

 necessitated her removal from the operational area; Hobart was one of the ships assigned to escort and assist with casualties. The Australian ship returned to Sea Dragon operations on 31 July. This continued until 16 August, and after maintenance at Subic, Hobart was attached to the gunline on 6 September. On 14 September, Hobart arrived in Subic, handed over responsibility to , and sailed for home.

During this deployment, Hobart fired over 10,000 rounds at 1,050 targets during 160 days at sea, and was fired on ten times, with no casualties. Hobart was awarded the United States Navy Unit Commendation

Second deployment

Hobart was deployed to Vietnam for the second time in 1968, relieving Perth on 31 March. On 13 April, the destroyer arrived on the gunline to relieve . Five days later, she began Sea Dragon operations with . The ships were unsuccessfully shelled by coastal artillery on 22 and 23 April, then spent the next three days attempting to attract attention from shore batteries so they could be bombed by aircraft. Hobarts participation in Sea Dragon ended in late April, and after maintenance in Hong Kong and Taiwan from 1 May to 20 May, she resumed gunline duties. This continued until 2 June, when the destroyer's guns required new barrels. On 11 June, the destroyer returned to the Sea Dragon area of operations, joining . During this deployment, boat traffic between the mainland and Tiger Island was seen as a priority, with gunline ships also granted approval to operate against targets in this area. Early in the month, problems with the 5-inch/54 guns aboard Hobart and several US destroyers appeared; Hobarts captain decided to only fire the guns in emergencies until the problem was clearly identified. The destroyer joined Hobart and Chandler to make up for the lack of firepower.

During the evening of 16-17 June, the three destroyers were ordered to undertake surveillance missions around Tiger Island, because of reports of North Vietnamese helicopter activity in the area. At 03:09, Hobarts radar picked up an aircraft approaching with no IFF

 transponder active. At 03:14, the aircraft fired a single missile at the ship, which killed one sailor, wounded two others, and damaged the chief petty officer's mess, air search radar and missile control compartments, and the ship's funnels. Two minutes later, the aircraft made a second pass and fired two missiles. The missiles hit simultaneously: one penetrated the superstructure and damaged the gunners' store, engineers workshop, and aft seamans' mess, while the other hit close to the original missile, causing further damage to the mess and missile control room, while also damaging the Tartar checkout room, killing another sailor, and wounded six others. These was also major damage around the destroyer's Ikara magazine, but as Hobart was not carrying any Ikara missiles at the time, the potential magazine fire did not occur. The aircraft came around for a third attack run, but was scared off when Hobarts forward gun turret, under independent control, fired five rounds at the aircraft. At 03:30, Edson reported coming under fire, and Hobart captain ordered the three destroyers to take up anti-aircraft formation. At 05:15, the three destroyers linked up with the cruiser (which had been hit by a missile from another aircraft) and the escorting destroyer , and continued anti-aircraft manoeuvering. After being relieved, Hobart sailed for Subic Bay, where the damage was inspected by RAN and USN personnel, including three admirals. Debris collected from Hobart and the other ships indicated that the missiles were of United States Air Force

The attacks on Hobart and the other ships were the capstone of a series of firing incidents between 15 and 17 June, and an inquiry was held by the USN into the incidents, with three RAN personnel attending as technical advisors. The inquiry found that a few hours before the attack on Hobart, Swift Boats PCF-12 and PCF-19, along with , were attacked by what they identified at the time as hovering enemy aircraft, but were believed to be friendly planes; PCF-19 was sunk in the attack.

Hobart underwent repairs in Subic Bay, and returned to duty on the gunline on 25 July.

During the evening of 27 July, Hobart was involved in another friendly fire

 incident; this time, shells from the ship fell close to a marine unit's command post and injured three marines. The fault was found to be with the marine unit's spotter, who was inexperienced, failed to signal the close proximity of friendy units to the target, and failed to fully identify the target before calling for five rounds of shellfire. Although Hobart was asked to rotate Sea Dragon duties on 2 August to relieve a destroyer experiencing gunnery faults, nine days early, the destroyer's captain refused, as he wanted more time to prepare the ship after the repairs, particularly as the air warning radars were yet to become operational, and the gun mounts were experiencing minor problems. The Sea Dragon deployment did not eventuate, and after operating near the Demilitarized Zone, Hobart was reassigned to gunfire support duties around southern Vietnam on 12 August.

Three days later, the destroyer rammed and sank a South Vietnamese fishing craft, but rescued the five crew and transported them to shore. At the end of April, the ship sailed to Subic for maintenance. After this was completed, Hobart returned to gunline duties on 11 May, and remained on station until 24 May, when the destroyer sailed to Singapore for maintenance. Hobart resumed gunline operations on 6 June; these continued until 28 June, when she sailed to Subic for rebarrelling. She returned to the gunline on 9 July, and operated until 29 August, when she sailed to Singapore for maintenance, then Bangkok for naval exercises. Returning on 13 September, Hobart was called to relieve on the gunline after an explosion in one of the American destroyer's gun mounts. On 22 September, Hobart sailed to Subic. The destroyer was relieved by Perth on 26 September. Two personnel were mentioned in despatches, and 23 Naval Board commendations were issued for the deplpyment.

During 1971, the Australian government decided to withdraw all forces from Vietnam by the end of the year. Hobart made no further deployments to Vietnam, and after completed her assigned operations in September 1971, no further RAN ships were deployed to the warzone for combat operations. Hobart received the battle honour
