C-14 China Cat Fast Attack Missile Boat
In May 2002 it was reported that China had sold Iran high-speed catamaran missile patrol boats. The first of the new C-14 patrol boats, referred to as China Cats, were reportedly observed by US military intelligence recently in an Iranian port. A Chinese delegation of technicians was in Iran to help the Iranian navy train and equip the new boats. These light 20 ton displacement boats are designed to carry up to eight C-701 anti-ship cruise missiles and usually have a single gun for self defense. It is a fast attack craft designed for high speed and low cost.
Catamarans have two parallel hulls separated by a deck structure; this design greatly increases the stability of the resulting boat. Catamaran type boats have long been known in the prior art. There are two recognized advantages of such boats. In the first place, when the boats are propelled at relatively high speed through the water, the upwardly flaring shape of the forward portions of the bottom surfaces of the two pontoons create a lifting effect which permits the boat hull to glide over the surface of the water, thus minimizing the frictional drag on the boat. Additionally, since neither hull normally strikes a wave at the same instant, the pitching of the boat produced by wave impact is significantly reduced.
Because catamarans have two hulls spaced apart, a catamaran is much less susceptible to water disturbances such as wave action. One disadvantage of prior art catamarans is that they tend to splash and spray water up over the top of the deck structure. This is not a problem if the user expects to get wet. Catamarans run on less wetted surface than their V-bottom counterparts, they use the concept of air entrapment between the two hull sponsons to create lift. Properly designed, the result is the most efficient hull, inch for inch and horsepower for horsepower, in the go-fast boat world. But catamarans can be a bit trickier to turn than V-bottoms.
Because of centrifugal force, a catamaran tends to lean outwards in a bend, just like a ship. It is possible to compensate for this lean by means of a small inclination of the bottom of the pontoons, which inclination opens outwards, in which case, when turning in a bend, the displacement of the pontoon on the side of the outer bend increases and correspondingly, the displacement of the pontoon on the side of the inner bend decreases. When the lean remains small, the horizon does not disappear behind the bow of the hull of the catamaran, and visibility in all directions can be maintained. By keeping the inclination of the inclined bottom small, it is further possible to lower the planing threshold of the catamaran and to reduce the displacement of the catamaran at the cruising speed, in which case the wave formation of the catamaran is reduced.
A catamaran has a center tunnel, the opposite sides of which form asymmetrical pontoons, which are mirror images of each other, and which pontoons have buoyancy, which has been adapted so that when the catamaran moves in water, the center tunnel functions as a combined water and air tunnel. When the catamaran is stationary in water, the ceiling of the center tunnel is in water. Moreover, the ceiling of the center tunnel curves in a cylindrically convex manner downwards when going from the bow to the direction of the stern only after an essentially horizontal portion of a distance, which portion is located between the pontoons.
The air that travels through the mouth of the center tunnel of a catamaran may be carried to under the catamaran over a distance before it is being started to restrain downwards on the cylindrically convex ceiling. In this case, air that has been led between the pontoons up to the distance can no longer escape in the vertical and lateral directions. By means of a cylindrically convex ceiling, it is possible to restrain and guide air towards water, preventing the free flow of air. When the flow of air slows down when hitting water, the static pressure on the lower side of the ceiling of the centre tunnel of the catamaran may increase (the phenomenon here is ground effect). The closer the ceiling of the center tunnel moves from the surface of water, the greater the slowing of the flow and the increase in the static pressure below the ceiling of the centre tunnel of the catamaran caused by it may be. In this case, it is possible to achieve lift even at small speeds, when the ceiling of the centre tunnel is still almost in water. Moreover, it is possible to decrease the hitting of the ceiling of the center tunnel with the waves by taking the curving of the ceiling of the centre tunnel towards the stern, in which case the buoyancy of the pontoons may begin to lift the bow before a wave hits the ceiling of the center tunnel.
Both pontoons have a bottom comprising a straight portion and a curved portion located at the bow side from the straight portion. The curved portion of the bottom is inclined in the width direction of the catamaran at an angle upwards from the plane of the normal of the examination point at the edge of the surface of the side when the angle opens to the direction of a shell plate, and which curved portion of the bottom in the area of the bow of the catamaran from the stern to the direction of the bow has been curved upwards and essentially at the same time turned inwards so that the angle increases when moving from the area of the stern of the catamaran to the area of the bow. So it is possible to improve the manoeuvrability of the catamaran at smaller speeds, and on the other hand with the cutting bow it is possible to improve the penetrating capacity of the bow in rough sea.
The structure of the boat is made up of two walls, which have the possibility of carrying light anti-shipping weapons. The boat is 23 meters long and a 12.7 mm machine gun was mounted in the back of the boat. It was also equipped with a 23 mm submachine gun and a cockpit with a 107 mm rocket launcher consisting of 16 barrels and a 30 km rane search radar at the top of the rocket launcher. The speed of the boat is 93 km / h, and the rangeof its war operations is about 500 km, that is, it is capable of folding 30% of the coast of the Arabian Gulf to carry out its tasks in less than 6 hours at full speed.
This force has gained much experience with the strategy of radar boats in various operations such as Valfajr 8, Fatah Al-Awiya, the US Navy clash in the 66th, as well as maritime patrols in the Persian Gulf and the Strait of Hormuz, which has become an effective force in the region.
The upward trend of the naval forces of the Revolutionary Guards and the dramatic growth of this force continued under the command of Major General Yahya Rahim Safavi and Admiral Saffari, and in light of this move forward, during the commanding period of Maj. Gen. Mohammad Ali Jafari and Admiral Ali Fadawi, protection and control The Oman Sea and the Persian Gulf were transferred from the Navy to the Naval Force.
In order to prevent parallel missions on the coast and the waters of the country, a separate description of the separate tasks for the army and the IRGC in the maintenance of the sea was defined that the maintenance and security of the Persian Gulf and its borders to the Guards and beyond, in addition to The Caspian Sea was handed over to the army. Based on the separation of the duties of the two naval forces of the Revolutionary Guards and the Army, the Revolutionary Guard, with its own unique systems and equipment, such as radar and missile floaters, missile systems and drones, is responsible for securing and protecting the interests of the Islamic Republic of Iran in the Persian Gulf and the Strait of Hormuz.
