By 1952, senior Naval appointments had begun to be filled by Indian officers,[36] and by 1955, basic training for naval cadets was entirely conducted in India.[37] In 1956, Ram Dass Katari became the first Indian flag officer, and was appointed the first Indian Commander of the Fleet on 2 October.[38] On 22 April 1958, Vice Admiral Katari assumed the command of the Indian Navy from Carlill as the first Indian Chief of Staff of the Indian Navy.[39] With the departure in 1962 of the last British officer on secondment to the Navy, Commodore David Kirke, the Chief of Naval Aviation, the Indian Navy finally became an entirely Indian service.[40]
