This video is an English Documentary about Trident II missile
The UGM-133A, Trident II, or Trident D5 is a submarine-launched ballistic missile also known as (S L B M), deployed by the British and the US navies.
This missile is built by the Lockheed Martin Space Systems in Sunnyvale California.
It was first inducted into the navy in March 1990, since then this missile is still in service.
The Trident II is considered to be a durable sea-based system capable of engaging many targets.
It enhances the U.S. position in strategic arms negotiation with performance and payload flexibility that can accommodate active treaty initiatives. The Trident II increased payload allows nuclear deterrence to be accomplished with fewer submarines, and its high accuracy – approaching that of land-based missiles – enables it to be used as a first strike weapon.
Trident II missiles are carried by 14 US Ohio and 4 British Vanguard-class submarines, with 24 missiles on each Ohio class and 16 missiles on each Vanguard class. USS Tennessee (SSBN-734) was the first submarine to be armed with Trident II, and there have been 157 successful test flights of the D5 missile since design completion in 1989, the most recent being from the USS Kentucky (SSBN-737) in November 2015. The D5 is the sixth in a series of missile generations deployed since the sea-based deterrent program began 60 years ago. The Trident D5LE (life-extension) version will remain in service until 2042.
The missile (UGM-133A Trident II), can carry heavy pay loads, warheads include, W88 (475 kt) and W76 (100 kt) warheads.
The Unit Cost Price of this war machine is US$37.3 million. The range of trident missile system is 7,840km or (4,230nmi) while carrying full load, its range exceeds with reduced payloads up to 7,456 mi or (12,000 km) approximately. Exact range of this missile is classified.
Maximum speed of this missile is approximately 18,030 mph or (29,020 km/h) or (Mach 24).
The missile uses MK 6 Astro-inertial guidance as its navigation system which is a very strong system in receiving GPS updates.
Trident II is a very accurate and precise in selecting and hitting its targets it can also be used as the first strike weapon without any worries. Trident II runs with 3 stage rocket, each stage contains a solid fuel rocket motor. Missile direction is controlled by using the thrust vectoring technology also known as T V C.
Missile is pushed by the gas to force the missile to come out of submarine’s missile launch tube. when the missile reaches the surface of the water, ignition starts up the thrust vectoring system to align the missile into the right direction before flight, after that the first stage motor ignites, after 65 seconds and after putting the missile into speed gear, missile ejects the first stage motor, ignites T V C and then re-align itself to the targeted place.
