Transition to Triumph book is the history of the Indian navy covers the period from 1965 to 1975.  

• Indian Naval history (Transition to Triumph) also records that “by themselves the ships of the Eastern Fleet were too few and too slow to enforce contraband control and help would be needed from Vikrant’s aircraft.  
• But the extraordinary extent to which Vikrant’s aircraft actually succeeded in assisting ships in contraband control and apprehending merchant ships, over and above their air strikes against East Pakistan, came to be fully realised only after the war.”
