On the other hand K-335 features a tube towed array dispenser as seen on Yankees, Oscars, Yasens, Typhoons and Deltas. Towed array cable being fed into the bulb by the reel. The bulbs on Akulas were larger than others and were almost as big as a minibus. These subs needed the pod as they didnt have enough space between their inner and outer hulls to house the array there. It turned out to be a towed sonar array housing which was first seen on Victors after which they were fitted onto Akulas and Sierras. Originally the west thought that the bulb on the rudder was a new propulsion system or a new counter measure/weapon which could be deployed rearwards. Thus a smaller spherical array was sought after, but over head tubes meant it was only a minor increase in capability yet caused lots of problems. Tubes which deployed torpedoes from amidships couldnt be used at higher speeds but bow mounted ones could be used at comparatively higher speeds. The Russians stuck to cylindrical arrays even though Americans had spherical arrays as they wanted to stick with tubes mounted on the bow instead of amidships like the American subs. This array along with several small ones on the sail, wide aperture arrays and the towed array made the Akulas a potent sonar platform and this became a major factor in its supremacy over the LA.
Here we can see K-154’s cylindrical array on the bow as its covering was damaged due to some reason. These smaller surfaces were exclusively used for making small direction changes at high speeds. In this pic we can see that the rudder and stern planes have small sections which arent connected with the main controlled surface. She was named as Akula and thus NATO used it as the official reporting name for the entire class. This is K-284, ie the lead boat of the Akula class under construction. This article, like its preceding article on Typhoon has some very rare pictures of Akulas under construction, trials, refit and pics of her sensors. In this article we are going to deal with various design aspects of Akula class SSN using pictures. The Akula-class submarine is one of the most advanced submarines in the world, and it has been used in a variety of operations, including the Cold War and the War on Terror.
It is known for its stealth and maneuverability, and it is armed with a variety of torpedoes and missiles. The boats can also carry up to 50 UGM-109 Tomahawk cruise missiles for attacking land and shipping targets.The Akula-class submarine is a nuclear-powered attack submarine that was designed by the Soviet Union. However they also have extensive equipment for shallow-water operations, including a floodable silo capable of deploying eight combat swimmers and their equipment at once. They were built using HY-100 steel rather than HY-80 steel which is what previous classes had used. They were intended to combat the then-threat of large numbers of advanced Soviet ballistic-missile submarines in deep ocean, such as the Typhoon class, and to reply to the new Soviet Akula class attack submarines. They are quieter than the previous Los Angeles class submarines, larger, faster, have twice as many torpedo tubes for a total of 8, and carry more weapons, but were also much more expensive. The end of the Cold War and budget constraints led to the fleet being canceled at three boats in 1995, and led to the design of the smaller Virginia class. At one time, an intended fleet of 29 submarines was to be built over a ten-year period, later reduced to twelve. The Seawolf class attack submarine (SSN) was the intended successor to the Los Angeles class, ordered at the end of the Cold War in 1989.
