HMS Nigeria, a Fiji-class cruiser, was commissioned in 1940. A year later, she was made flagship of Task Force K, which operated in polar waters. In 1942, the cruiser moved to the Mediterranean, where she was engaged in escorting Maltese convoys. Starting the following year, Nigeria served in the Far East and off the coast of South Africa. In 1954, the ship was sold to India and renamed Mysore. She was immediately made flagship of the Indian fleet. In 1971, she was engaged in the Indo-Pakistani War and led the attack at the port of Karachi.
