Originally, the academy provided pre-sea training for the cadets of Nautical and Engineering Branches. First batch of 41 cadets successfully passed out from the academy in 1964.

In 1971 the academy was shifted to Karachi and was housed temporarily in the two blocks of Haji Camp; thereafter, 1976, the academy was relocated at purpose built huge infrastructure at its current location.
