After her return, "Volunteer" was assigned to the support of Arctic convoys steaming between the United Kingdom and the Soviet Union. Accordingly, she and the destroyers , , and , the antiaircraft ship , the corvettes , , and , the Polish Navy destroyer , and the Free French Naval Forces corvette joined the escort of Convoy PQ 16 on 23 March for its voyage to the Soviet Union. German aircraft continuously shadowed the convoy, and German bombers, torpedo planes, and submarines carried out heavy attacks against it. On 25 March, "Volunteer" rescued the pilot of a Hawker Hurricane fighter from a Catapult Aircraft Merchantman (CAM ship) after the American merchant ship "Carlton" mistakenly had shot him down. Before German attacks ceased, PQ-16 had suffered the loss of seven of its 34 merchant ships and damage to four others and to "Garland". On 30 March, the escorting ships handed the convoy over to the Eastern Local Escort and proceeded to port in North Russia, where "Volunteer" remained until she and the same ships that had protected PQ 16 escorted Convoy QP 13 from the Kola Inlet to the United Kingdom in a voyage which began on 26 June 1942. After an uneventful passage, "Volunteer" detached from the convoy at sea near Bear Island on 5 or 6 July 1942 (sources differ) to proceed to the United Kingdom.
