Speaking to reporters, Verma said, "Targeting ships at high seas is not an easy task or as simple as land warfare."
He was speaking on the sidelines of a seminar on aircraft carriers organised by the National Maritime Foundation here.
"There are hundreds and thousands of ships in the sea at any given time. It is extremely important to spot the ship before targeting it. There are limitations in terms of maritime reconnaissance and long-range searches," Verma said.
He was responding to a question when asked about the threat posed by Chinese Anti-ship Ballistic Missile Programme.
