We have a lot of confidence on how we all operate with regard to Malabar," a US navy official told a select group of reporters here via satellite link from onboard nuclear-powered aircraft carrier USS Ronald Reagan operating in the contentious South China Sea.
During this year's drill, the focus was on anti-submarine warfare, search and seizure, besides maritime patrol, helicopter operations and explosive disposal exercise.

Last month, India, Japan and the US had taken part in Malabar exercise near the troubled waters of East China Sea that saw over 100 aircraft and 22 naval ships, including a nuclear submarine, in action.
It was held close to the uninhabited isles in East China Sea, called Senkaku by Japan, which controls them. However, they are aggressively claimed by China as its Diaoyu islands.
Indian ships, which participated in the exercise, were from the Eastern Fleet and included INS Sahyadri and INS Satpura, indigenously built guided missile stealth frigates, INS Shakti, a modern fleet tanker and support ship and INS Kirch, an indigenous guided missile corvette.
