1620, the Dutch physicist 科尼利斯德 Lei Buer built in the UK the world’s first submarine. Since then, countries emerging design and construction of submarines.

after the outbreak of World War I, German submarines, naval attaches great importance to the role, sending a large number of active submarine U-marine traffic in the UK online. September 5, 1914, the British “pioneer” warship was a German submarine fired a torpedo hit the ship more than 250 officers and men did not have time to figure out who the attacker is on and the “pioneer” was bottom of the sea with . 17 days, 3-ton British cruiser has died at the hands of the German submarine.

these two wars have greatly shocked the country was at war. Submarine warfare in the military and belligerent not only to huge economic losses, but also to the officers and men of war brought tremendous mental pressure. The face of the growing threat of submarine, various countries began large-scale war anti-submarine warfare.

Initially, the warring countries, mainly through one’s own base, fortified harbor and waterways in the distribution networks and mine the potential barriers, etc., in order to prevent the enemy submarine activities. Sailing ships, to send someone around with eyesight observe whether there is a submarine periscope out of the sea and the sea there is no submarine discharge of fuel and waste. At that time, a weapon against the submarine depth charges only. This is a sunken depth charges, and only when the submarine campaign to the ship is at the bottom, the depth charges into the sea may have hit the submarine. This approach is clearly anti-submarine has many limitations, is far from the growing threat of submarine deal.

Thus, the warring countries began to actively fight against the submarine design and manufacture of anti-submarine ships, hunting submarines came into being.

early submarine chasers, a displacement not exceeding 100 tons, speed 10 or so, do not search for sonar and other equipment, optical instruments can only be used in the search for surface or the state of the submarine periscope. World War II, submarine chasers performance has been greatly improved, with a displacement of 300 tons, maximum speed 20 knots, equipped with deep anti-submarine rocket bombs, hedgehog bombs, depth charges and other large-scale anti-submarine weapons. After the 1950s, hunting submarines into the modern stage of development: The main anti-submarine homing torpedo weapons; equipped with the excellent performance of the hull sonar, towed sonar and command and control automation systems; use of light high-power diesel engines and gas turbine combined power device, the maximum speed 40-60 knots; hull aluminum alloy, mobility, airworthiness, Submarine and anti-submarine capability has been greatly improved.

performance of modern hunting submarines equipped with advanced sonar, radar, anti-submarine homing torpedo tubes, anti-submarine rocket launchers, guns, depth charges, launchers, guns and electronic warfare systems, naval systems, command automation, full load displacement of 500 tons, speed 24-38 knots, cruising range 700-3000 nautical miles, 3-10 self-force day and night, under the sea state in the 3-5 effective use of weapons, 5 – 8 sea conditions to safe navigation.
