Lanba added that the navy had apprehended 120 pirates.
"...navy remains committed to curbing this global menace," Lanba said.
"Since 2008, 70 Indian naval warships have been deployed, which safely escorted over 3,440 ships with over 25,000 mariners on board," Lanba added.
Lanba added that he did not think of John Allen Chau's death as a failure of "coastal security". Chau, an American, was recently killed by tribesmen on North Sentinel Island in the Andamans.
The Sentinelese are one of the world's last uncontacted tribes. Visitors are not allowed on to their island with the navy enforcing a three-kilometre buffer around North Sentinel.
