The ship continued her fire support mission on 10 January and then spent the next week patrolling Lingayen Gulf to protect the beachhead. During this period, she was called on to neutralize defensive positions, destroy ammunition dumps, and shell rail and road junctions to disrupt the Japanese ability to reinforce their positions. Heavy bombardment from "West Virginia" and the other ships flattened San Fabian. Over the course of the bombardment, she fired 395 main battery shells and more than 2,800 secondary shells. On 21 January, the ship departed at 07:07 to support ground forces fighting in the towns of Rosario and Santo Tomas to the north of Lingayen Gulf, opening fire at 08:15. She remained there for several days, providing fire support, before returning to Lingayen Gulf on 1 February. The ships of TG 77.2 thereafter covered transports carrying supplies for the Army as they arrived to unload their cargo at the beachhead. On 10 February, "West Virginia" departed for Leyte Gulf.
