<> "Kilo-class submarines.

The K-class conventionally powered attack submarine (Kilo Class, Kilo is the transliteration of Kilo) is the third generation of the Russian Navy's post-war and current main diesel-electric submarine. The prototype of the "Kilo Socks Eyes Changlo" class was the 877 class plaice type, and then the "Kilo" class was modified after modernization and other modifications to form the "Kilo" class (Improved Kilo), and the Russian side numbered 636 Warsaw Song type. The Kilo class in India was modified and given the name Sindhughosh.

The "Kilo" class is currently the largest class of submarines exported by Russia. It is known for its powerful firepower and low noise. Since the successful development of nuclear-powered attack submarines in the former Soviet Union, the research on conventionally powered submarines has also decreased considerably.

R&D history: The Kilo-class diesel-electric conventional submarine was designed by Russia's famous Ruby Design Bureau. Since World War II, the former Soviet Union has developed nearly 100 attack conventional submarines of five generations and 10 classes.

The K (Kilo) class (also known as the "Kilo"-class) submarine is its fifth generation and the latest generation of submarines in service. The Kilo-class diesel-electric submarines, developed in 1974 by the former Soviet Union's Ruby Design Bureau, are mainly used to snipe enemy ships trying to approach their country's territorial waters. In 1974, the Navy of the former USSR and the Ministry of Shipbuilding Industry of the USSR signed an agreement on the development of a new conventional submarine, type 877.

The agreement puts forward a series of new requirements for this class of submarines in terms of power, armament, and noise reduction.

Equipment: At present, a total of 52 Kilo-class submarines of various types have been built, and in addition to equipping the Russian Navy, they have also been exported to China, India, Vietnam, Iran, Algeria, Poland and Romania.

The latest, Los Angeles-class, has an underwater displacement of 6,900 tons, more than 2,000 tons more than the Sturgeon-class, and the United States plans to build 62 ships, 47 of which are now in service, and since the 32nd boat, all of them are equipped with vertical launch canisters for Tomahawk cruise missiles. This is because the U.S. Navy believes that the ability to launch multiple ** with only 4 torpedo tubes is insufficient.

The Los Angeles class has an underwater speed of 32 knots, a diving depth of 450 meters, and a crew of 133 (13 officers, 120 enlisted men), which is only 26 more than the Sturgeon class. However, despite the much larger hull, the interior space is not very spacious.

In terms of underwater detection systems, the most notable is the Los Angeles-class towed line array sonar system. This sonar system is towed at the stern of the boat, out of the noise zone of the boat, and can listen to targets in the stern azimuth that has traditionally been considered a blind spot for listening.

As mentioned earlier, the Sturgeon class has a good ability to maneuver under the ice, but the Los Angeles class did not pay much attention to this in the design. However, with the improvement of the maneuverability of Soviet and Russian nuclear submarines under the ice, the Los Angeles class has also strengthened the hull since the 34th boat, and the bow rudder has also been moved from the command platform enclosure to the front of the hull, and it can be embedded. In this way, when navigating in the ice sea, it is conducive to breaking through the ice.
