She cleared the Gulf of Tonkin on 4 May, headed back to the United States, and made Long Beach on the 23d.
Somers resumed operations out of Long Beach until 9 July when she began a month of pre-overhaul preparations.
On 9 August, the guided-missile destroyer entered Long Beach Naval Shipyard to commence regular overhaul.
The overhaul lasted until 3 December and, following that, she went into a period of restricted availability which carried her through 31 December.

After a voyage to Singapore and back, she joined the carriers in the Gulf of Tonkin on 9 May. Her tour of duty in the Far East lasted until late October.
She cruised with the aircraft carriers in the Gulf of Tonkin five times during this deployment, rendered naval gunfire support three times, and stood duty on the south Talos station and PIRAZ station once each.
Between line periods, she normally put into Subic Bay, but managed to visit Sasebo, Japan, and Hong Kong.
Somers returned to Long Beach on 9 November 1972.

Two periods of operations from her home port separated by two months of restricted availability at Long Beach took up the first nine months of 1973 for Somers.
