HMS Tiptoe arrived at HMS Dolphin, Gosport, for the last time on August 28, 1969, after 25 years’ service.
In her first commission she fired what is believed to have been the final torpedo attack of the Second World War when she sank two Japanese merchantmen in the Java Sea.
The boat, named by Sir Winston Churchill, arrived in Portsmouth Harbour with ballet dancer Judith Wright, 13, of Wych Lane, Bridgemary, Gosport, on the bow.
During her service Tiptoe covered 300,000 miles and 50,000 on her last mission. After berthing she went quietly to the breakers’.
