Researchers at the Department of Homeland Security in the United States are into the development of a BIOSwimmer unmanned underwater vehicle, which would mimic the saltwater fish Tuna, says a recent report.

The plan to create a robotic tuna came amid current pictures of the borders of the state. It was seen by the group that numerous volumes of cargo are shipped from major sea ports like the busiest Port of Los Angeles, the Port of New York and the Port of Long Beach.

But, the efforts to tighten security as well as ensuring no contraband were all failing the DHS. Therefore, the tuna is being designed in a way that it could enter harbors as well as tighter waterways. It is being said that the same would help it in spotting signs of trouble.

The team is of the opinion that tunas are already gifted with a powerful and alert underwater design. And the new model would, taking sensors and cameras along with it, prove more alert. However, it would be controlled using a laptop by someone on dry land.

It has been told that Phase I development cycle is complete and Phase II development is on with a hope to see a commercial version for the oil-shipping industry ultimately.
