The test began at 2.15pm at the Diem Dien Port in Thai Thuy District, Thai Binh Province.
Two fishing boats escorted the submarine to the estuary.
The submarine is coated with a layer of glossy black paint. Its name – Truong Sa 01 - is on the side. The national flag is drawn on the cabin and the side doors.
The submarine was controlled by businessman Nguyen Quoc Hoa.
In this test, the submarine used the new gas recirculation system and was equipped with a new radar. However, due to high winds and waves and problems during the transportation of the submarine, the rudder and propeller were damaged so the trial was stopped in the middle.
The submarine has a length of 9 m, a height of 3 m, equipped with two 90 Hp diesel engines, operated by an air-independent propulsion system (AIP). Maximum design speed is 40 km/h, 800 km radius of operation, dive time of 15 hours, and maximum diving depth of 50 m.
It is manufactured by Mr. Hoa, the director of a print company in Thai Binh. |
