re-designated Task Force 57, the British Pacific Fleet was again involved in operations in late March 1945, when it launched attacks on the Sakishimo-Gunto airfields, a task it repeated in early May. On 4 May 1945 King George V led battleships and cruisers in a forty-five minute bombardment of Japanese air facilities in the Ryukyu Islands. As the Allies approached the Japanese homeland, King George V was dispatched in mid-July to join the US battleships in a bombardment of industrial installations at Hitachi. King George V fired 267 rounds from her 14-inch guns during this operation. The task force then moved on to Hamamatsu in southern Honshu, where it carried out a further bombardment of aviation factories. During the Okinawa campaign, the battleship supported four fast carriers of the British Pacific Fleet. Her last offensive action was a night bombardment of Hamamatsu on 29 and 30 July 1945.
dropping of the atomic bombs on Hiroshima and Nagasaki and the surrender that followed, King George V moved with other units of the British Pacific Fleet into Tokyo Bay to be present at the surrender ceremonies.
 Post war
What surprised me was few Brits had a clue what had happened in the Far East, common Question was" what war was that?" Mind you the war in Europe has ceased ten months previously.people had other things on their mind.
