The ship increased speed and moved rhythmically on the lake. Because the water level in the lake is only 2m, the water just covered the ship body.

Around 12.10pm, Hoa got ashore after successfully testing the submarine. Hoa said there was no technical problem during the test.

At the end of the testing process, Hoa said he planed to manufacture another submarine named Truong Sa 2. He said he would test the submarine at sea when he gets a license.
