The UGM-133A (UGM-133A) is a third-generation submarine ballistic missile developed by the U.S. Navy and the most important means of nuclear strike at sea in the United States.
In the 70s of the 20th century, the Soviet Union gradually strengthened its nuclear capabilities, and at the same time strengthened its anti-submarine attacks on submarines, and the US Navy launched a long-range submarine missile program and proposed a new submarine that was further away than the "Poseidon". Lockheed, in its capacity as general contractor, proposed to do it in two phases:
First of all, a new and improved version of the "Poseid" called "Poseid" was developed, which has the same dimensions as the "Poseidon missile" and can be used in existing ballistic missiles. Then, a new type of submarine-launched missile with a larger caliber will be developed, although it will also have to create a new nuclear submarine. Eventually, the first one became Trident I-4, while the third became Trident II-5.
In 1983, the UGM-133A ballistic missile was officially launched, in January 1987, its first Trident II flew on a land-based flat platform, in March 1989, its first submarine rocket, and in March 1990, it claimed to have preliminary combat performance.
The UGM-133A ballistic missile is an important part of the U.S. Navy's strategic ** system, and the "Trident I-4" is the same class 3 solid-state missile, but it applies a large number of unprecedented new technologies, including the new NEPE-75 (nitrogenous resin modified polyether-75) energetic rocket engine, carbon fiber epoxy shell, carbon carbon telescopic nozzle, GPS star orbit inertial navigation integrated navigation system, etc. The maximum distance is 3837 km, the maximum distance is 4000 km.
The UGM-133A is much larger and can carry eight MK-5 re-entry vehicles, as well as eight 475,000-ton W88-class nuclear warheads, which can reach a distance of 11,000 kilometers. At full load, the three-pointed IID-5 can have a nuclear warhead of up to 14 rounds, but its range will be compressed. But according to the START agreement, they can only carry 8 nuclear warheads.
The UGM-133A missile carried by the UGM-133A missile, after GPS correction, has a circular probability deviation of 90 m, and has the ability to strike at a solid target for the first time, and can directly attack the Soviet Union's solid ICBM launcher and the strengthened underground combat command. It can carry eight 100,000-ton W-76 IV autonomous re-entry vehicles, usually ten different types of re-entry vehicles equivalent to 475,000 tons of W-87, and can also carry warheads with controllable re-entry vehicles.
The UGM-133A missile can be installed on the USS Ohio submarine in the United States, because of its long-range attack capabilities, it can attack any point in the northern hemisphere from American seaports without the need for ocean-going cruising and proximity to the enemy's well-defended coast.
Currently, the UGM-133A ballistic missiles are installed on the USS Ohio (24 units) and the USS Vanguard (16 units) of the British Navy, nine of the Ohio were already installed with this missile at the time of manufacture, and the other eight were originally equipped with one type of missile, which has now been converted into a No. 2 missile, a total of 408 Trident II missiles are installed on seventeen submarines. The British side offered 4 rockets that could carry 16 Tridents, for a total of 64.
The last 10 of the 18 Ohio type ballistic missile submarines are equipped with the Trident D-5 type, while each submarine is armed with 24 Trident IID-5s. The submarines of the first eight countries were equipped with the Tri-1-4 type, four of the first four countries have been replaced by a cruise missile, and the last four countries used three three-pointed D-5 types. With the adoption of a single warhead by the "People's Army No. 3," the "Peacekeeper" has been retired, and the three-tip D-5 is the only multi-combat intercontinental missile currently in the possession of the United States. The missile is the most important component of the US nuclear program, and by the 2004 year, the production of this missile reached 425 units, and in subsequent years it was increased by 5 to 12 units. The service life of this model of the Tri-Pointed Ballistic Missile has been increased to 42 years before the new generation of SLBMs is put into service, in order to ensure the deterrent effect of the United States against its maritime nuclear **.
On December 19, 2009, the U.S. Navy successfully completed the launch of the Tri-Pronged II submarine-launched intercontinental missile (SLICM) aboard the Ohio-class SSBN 732 Alaska Atlantic, the third Trigemin-II submarine-launched ICBM since 1989, setting a record for successful tests of this type of ballistic missile.
With the strong technical strength and industrial background of the United States, the UGM-133A missile is still one of the most powerful submarine-launched missiles in the world. Compared with the submarine-launched missiles that have been put into use or are being developed in the world, their overall scientific and technological level has always been in the forefront of the world, and they have a relatively high technical level and high reliability. Due to their massive use and excellent performance, the US maritime nuclear forces remain unique in the world for the foreseeable future. Like, bookmark, and see you next time!
