Repaired and refitted at Chatham Dockyard from December 1939 until July 1940. After repairs she went to the Mediterranean. She was refitted at Chatham dockyard between May and October 1942. She returned to the Mediterranean upon completion of her refit and was almost immedeately badly damaged by bombing on 1 January 1943. She went to the United States for repairs at the New York Navy Yard and was out of action until October 1943. She again returned to the Mediterranean but was recalled to home waters for the Normandy invasion in June. Once again she returned to the Mediterranean for the invasion of southern France in August. She remained in the Mediterranean for the remainder of the war. HMS Ajax was decommissioned in February 1948. Initially intended to be sold to Thailand but this deal did not materialize.

13 Dec 1939
Battle of the River Plate.
The German pocket battleship Admiral Graf Spee intercepted what was thought to be a small convoy of merchant ships 150 miles off the River Plate estuary. The convoy turned out to be three British cruisers of Commodore Sir Henry Harwood's squadron. Consisting of the light cruisers HMS Ajax (flagship of Commodore Sir Henry Harwood, RN, Capt. C.H.L. Woodhouse, RN in command), HMNZS Achilles (Capt. W.E. Parry, RN) and the heavy cruiser HMS Exeter (Capt. F.S. Bell, RN). They initially identified the Graf Spee's smoke as a merchant ship and HMS Exeter was detached to take a message to her, but soon the mistake was realised. With the British squadron now split (as planned before the battle) action commenced at with the Admiral Graf Spee opening fire at 0615 hours. The subsequent battle saw the cruiser HMS Exeter badly damaged with all her guns put out of action but still seaworthy, she suffered 61 killed and 23 wounded and was forced to make for the Falkland Islands to carry out repairs. HMS Ajax and HMS Achilles were both damaged and suffered casualties, HMS Ajax 7 dead and wounded and HMS Achilles 4 dead. They both shadowed the Admiral Graf Spee into Uruguay territorial waters where she entered the port of Montevideo. The Admiral Graf Spee suffered 36 dead and 60 wounded, hit by seventeen 6 inch shells and two eight inch shells, with water purification and desalination plant destroyed and kitchens wrecked she was allowed just 72 hours to make good her the damage that threatened her seaworthiness she was unable to do so. On the 17th December she left Montevideo with a skeleton crew, anchored just outside the 3 mile limit and after the crew left her she was blown up and scuttled to prevent her falling into British hands. Her captain later shot himself.

While on the return trip the Mediterranean Fleet was sighted by an Italian aircraft. The Italian Navy tried to intercept them in the Ionian Sea. In the night of 11/12 October the first Italian torpedo boat flotilla with Airone, Alcione and Ariel attacked HMS Ajax. The attack failed and Ajax sank Airone and Ariel, Alcione escaped. A little while later the Italian 11th destroyer flotilla, with Artigliere, Aviere, Camicia Nera and Geniere arrived at the scene. They were surprised by the radar-directed gunfire from HMS Ajax. Artigliere was heavily damaged and Aviere was lightly damaged. Camicia Nere tried to tow Artigliere away but she was sighted by a British Sunderland aircraft that homed in 3 Swordfish aircraft from HMS Illustrious. However, the torpedoed they fired didn't hit the Italian ships. Later the British heavy cruiser HMS York arrived at the scene. Camicia Nera quickly slipped the towing line and sped off. After her crew had left the ship Artiglire was sunk by York.
