It has an area of 99.1 square kilometers and a population of about 430,000 people. Originally a small fishing village, it was built as an ironworks in 1865, and was converted into a shipyard in 1871; in 1884 it became a military port guarding Tokyo Bay for the defense of the capital, and was established as a city in 1907. The city was established in 1907 and became a U.S. naval base after World War II, and was designated as a trading port in 1948. The city was established in 1907. After World War II, it was used as a U.S. naval base and was designated as a trading port in 1948. The city is home to the Japan Maritime Self-Defense Force (JMSDF) Fleet Command. In the east, there are two excellent harbors, Yokosuka and Nagaura. Nagaura is also one of the Antarctic whaling bases. The city has a military school, a military research institute and an atomic energy research institute. The city streets run along the bay shore in a rectangular shape. The city center is a commercial and residential area. In the north of the city, there are automobile, shipbuilding and chemical industries in the Ochihama and Urago areas; in the Tanoura and Nagaura areas, there are electric and automobile industries; in the southeast of the city, there is a traditional shipbuilding industry in the Uraga area; and in the Kurihama area, there are fishery processing and coal-fired power generation industries.
Yokosuka Port Naval Base
Located in Yokosuka Port on the east coast of the population of Tokyo Bay on Honshu Island, Japan, the port is connected to Yokohama City in the north, and Yokosuka City in the south and the east coast of Yokosuka City, and the port is blessed with conditions such as berthing facilities, ship repair capacity, oil and ammunition storage equipment and rest facilities for soldiers, and has all the conditions required for a naval base, and it has been known as the first naval port of the East Pacific Ocean. The harbor has wide waters (the waterline area reaches more than 30 square kilometers), the water depth is slow (the water depth is 7~30 meters, the current flow direction is basically the north of the west date south east direction, the speed is about 1 knot), no need to dredge, it is one of the few good natural harbors in Japan. The entire harbor area is shaped like the palm of a person's hand, with the "thumb" directly touching Yokohama City as the fourth district; on the root of the "forefinger" divided by Gosai Island, there are two breakwaters (the east breakwater and the northeast breakwater), and the northeast breakwater divides the palm into two, and the northeast breakwater divides the "palm" into two, and the northeast breakwater into two. The northeast breakwater divides the "palm" into two, the outer half of which is the outer harbor and the quarantine anchorage, and the inner half of which is the third area of the inner harbor. The rising tide in the inner harbor is north-northwest, speed 0.6-0.7 knots; the falling tide is southeast and south-southeast, speed 1-1.2 knots. The rising tide of the outer harbor is northward, with a speed of 1.1 knots; the falling tide is southward, with a speed of 1 knot. Into the harbor after the navigation signs are mainly, breakwater end of the light pile and the corresponding signal station as well as the island of Saru and other isolated day markers.
The first area of Yokosuka port (which has been designated as a military restricted area, prohibiting general ships from entering) is the largest and most functional U.S. naval base in the Far East, and has been evaluated as "one of the largest and best conditioned bases among the U.S. overseas naval bases", covering an area of about 2.3 million square meters, which used to be a naval base of the old Japanese Empire, and there is also a naval base of the former Imperial Japan. The base covers an area of approximately 2.3 million square meters and was formerly a naval base of the old Japanese Empire, and also includes the old navy's Yokosuka capital, a naval factory, a marine corps, a school, and other buildings. The base's predecessor was the Yokosuka Iron Works, the first shipbuilding factory established by the Edo Shogunate of Japan in 1865, which was later transferred to the Ministry of the Navy by the Meiji government in 1872 and renamed the Yokosuka Naval Factory in 1903, giving the base the shape of a naval base. In 1903, it was renamed "Yokosuka Naval Factory" and took shape as a naval base. With the emergence of the Imperial Japanese Navy at the end of the 19th century, and during the Russo-Japanese War and the First World War from 1904 to 1905, the shipbuilding capacity of the factory was greatly improved, and it had the ability to build cruisers, battleships, and other major ships of the time. Until World War II, the total number of employees had reached more than 40,000, not only the ship repair capability reached the first-class level at that time, and became the base camp of the old Imperial Japanese Navy forces (now the base as the 7th Fleet's underground headquarters, which is the war room of the former Imperial Japanese Navy). 1945 Japan surrendered, the United States landed in Yokosuka on August 26 8 of the same year, took over the base and established the shipyard one after another in 1947 to build ships and ships of the Japanese Navy. In 1947, the U.S. established a ship repair department, a supply depot, and a harbor department. From then on, the U.S. became involved in Yokosuka. Subsequently, the U.S. Army requested Japan to provide it with a base for its needs in the Far East, and the San Francisco Peace Treaty was signed. Among the provisions of the Japan-U.S. Security Treaty, it was clearly stated that the Japanese government should provide bases for the U.S. forces in Japan. Thus, in order to fulfill the provisions of the security treaty, in July 1952, Japan formally made the Yokosuka base available to the U.S. military.
After the U.S. military officially moved into the base, a series of additional repairs and expansions were made to various facilities. In order to be able to dock a 160-meter light cruiser and a 170-meter long Spruance-class destroyer, the maintenance pier for destroyers No. 6 and No. 7 was expanded from April to November 1985, increasing the length of the pier from 118 meters to 172 meters. At the same time, a concrete piled mooring island (shaped like a protruding embankment pier) was constructed in the water 54 meters from the pier, with a steel bridge connecting the "island" to the pier. An area of approximately 280,000 square meters of water around the population of the bay was dredged and 70,000 square meters of land was reclaimed from the dredged sand, which not only restored the berthing capacity of the mooring area, but also provided man-made land for residential construction and other military facilities. Pier 12, where aircraft carriers and nuclear submarines are often docked, and a new warehouse near the 7th Submarine Group Command were also newly constructed through rock-cutting and leveling; and a mine commissioning facility used with the Japan Maritime Self-Defense Forces*** was relocated to Agatsushima Island, where the site was expanded at least 10 times larger than the original one, to 210,000 square meters, and was renamed as the Mine Repair Facility.
At present, the U.S. Army in the base **** there are a variety of docks 18, with a total length of 2,516 meters, divided into 19 berths (14 ~ 17 berths in the 6th in the dockyard), which is a small harbor area since 1966 is a nuclear submarine often docked berths, and there is no radiological monitoring columns. The base has a U.S. Navy Command in Japan, Yokosuka Fleet Base Command, 7th Submarine Group Command, Ship Repair Department, Supply Depot, Engineering Center, Regional Medical Center, and other facilities, and 10 combat ships including the 7th Fleet flagship Blue Ridge, and the U.S. Naval Communications Unit in Japan, Marine Corps (Guard), etc. "Since October 6, 1978, the USS Blue Ridge has been stationed here. The USS Midway, one of the 10 combat ships, has been homeported since October 5, 1973, and has been decommissioned. Yokosuka is also the only carrier homeport among the overseas ports of the U.S. Navy (there are two wharves of 255 meters and 280 meters in length respectively, which can be used for aircraft carriers). This is because Yokosuka has good berthing conditions, on the one hand, there is Atsugi Airport nearby; on the other hand, it has outstanding ship repair capabilities, not only to make the "Midway" since the home port has been the highest rate, but also to provide a guarantee for the repeated extension of its service life.
Much of the importance of Yokosuka depends on the Naval Repair Yard's six dry docks. They were built during the old Japanese Navy period, with completion dates of 1869, 1884, 1894, 1905, 1916, and 1940, and docking tonnages of 4,000, 6,000, 1,000, 5,000, and 8,000 tons, respectively, and are still in good condition and usable today. Now 1 ~ 5 dock has been used with Japan * * * (l ~ 3 with the Japan Maritime Self-Defense Force, 4 ~ 5 and Sumitomo Heavy Machinery Industries, Inc.), the largest volume of 220,000 cubic meters of the No. 6 dock is still used by the U.S. Navy alone. The dock was originally built for the construction of the 3rd Yamato-class battleship "Shinano" (which was later converted into an aircraft carrier, and was torpedoed and sunk by a U.S. submarine in November 1944), and is now used mainly for aircraft carrier repairs, and is the only U.S. dock west of Hawaii that can accommodate carriers, and there is not even a single dock that can accommodate carriers in Guam!
So, according to the U.S. Navy's "global strategy", Yokosuka is the base it must rely on, and it is also an important base in the Western Pacific. The most important thing about Yokosuka, especially for the 7th Fleet, is that it has a strong capability to repair ships. Although the base did not cover the same area as the original U.S. Subic Naval Base in the Philippines, its naval repair yards repaired a wide variety of ships and were superior in terms of experience and capability in the repair of military equipment, the basic quality of the workers, and the surrounding industrial capacity that could be supported. For example, on July 29, 1980, "Midway" in the Philippines four South China Sea collision with the Panamanian merchant ship hull damage, although towed to Subic Bay for repair, but still request Yokosuka sent technical this staff to support, so once the 7th Fleet needs to repair the carrier, only the base can undertake, otherwise only to sail back to The base is the only one that can take on the task of repairing the carriers, otherwise they will have to sail back to Hawaii, or sail 14 days across the ocean to the west coast of the United States.
Base supply by the Yokosuka Naval Supply Depot is responsible for the ships and aircraft with fuel oil is mainly stored in the base of the port across the river on the island of Agatsuma, the island's oil storage facilities area of about 840,000 square meters, is with the Japanese *** with a large and small oil tanks in 37 districts, the storage capacity of oil is about 400,000 kiloliters, varieties of aviation gasoline, jet fuel, automotive gasoline, diesel oil and other heavy oil, such as 8 kinds of oil. In addition, in Yokohama there is a small diesel fuel depot (also is the old Japanese Navy legacy), covers an area of about 520,000 square meters, and there are 26 storage tanks, can store about 420,000 kiloliters of oil, and there are two should be up to 708 meters and 138 meters long trestle wharf, can be directly docked tankers loading and unloading of fuel oil. In the base not far from Puxiang, there is also an ammunition depot, the facility covers an area of about 180,000 square meters, and there is a perfect dock loading and unloading equipment.
It must be added that Yokosuka is still one of the main bases of the Japan Maritime Self-Defense Force (JMSDF), with a water area of more than 8,000 square meters and a depth of 7 to 23 meters, not only is the Japan Combined Fleet Command headquarters, but also the entire maritime Self-Defense Force ships were 40% of the total number of ships (about 115) are also berthing in this. Specific Japan Maritime Self-Defense Force in Yokosuka base berthing forces are: self-defense fleet command, frigate fleet, submarine fleet, 1st and 4th frigate group, 2nd minesweeper group, 1st transport team, 2nd submarine team group, etc.; Logistical support system of the force are: 33rd Frigate and 37th Frigate (and there are four displacement for 1470 tons of Chikugo class frigate), 42nd minesweeper group, in addition there are Transport ships and 11,700-ton "Shirase" icebreaker, at the same time, with the U.S. Yokosuka Naval Base continued to expand, the Japan Maritime Self-Defense Force in Yokosuka base construction is also increasingly strengthened, in the early 80s, successively completed the Yoshikura No. 1, No. 2 wharf, so that in the past has been at sea to tie up the drums of the Maritime Self-Defense Force ships, usually Can also be directly docked at the pier to send material supplies or repair, and get the supply of electricity and steam, in general, a pier on each side of the use of the parallel way to rely on 2 ships, *** can dock 8, of course, if compared with the U.S. Naval Base in Yokosuka, in the logistical conditions of life, whether it is the conditions of accommodation or dietary environment there is a great deal of difference.
