The UGM-133A Trident II, or Trident D5 is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space in Sunnyvale, California, and deployed with the United States and Royal Navy. It was first deployed in March 1990, [ 6 ] and remains in service.
The Trident was built in two variants: the I (C4) UGM-96A and II (D5) UGM-133A; however, these two missiles have little in common. While the C4, formerly known as EXPO (Extended Range Poseidon), is just an improved version of the Poseidon C-3 missile, the Trident II D-5 has a completely new design (although with some technologies adopted from ...
The American large SSBN was the Ohio class, also called the "Trident submarine", with the largest SSBN armament ever of 24 missiles, initially Trident I but built with much larger tubes for the Trident II (D-5) missile, which entered service in 1990. [26] [27] The entire class was converted to use Trident II by the early 2000s. Trident II ...

Once the problem was understood, simple changes were quickly made, but the problem delayed the entry into service of Trident II until March 1990. [122] Trident II D-5 is more sophisticated than its predecessor, Trident I C-4, and has a greater payload capacity. All three stages of the Trident II D-5 are made of graphite epoxy, making the ...
A Trident II missile, operated exclusively by the US Navy and Royal Navy. Each missile can carry up to 12 warheads. [1] A multiple independently targetable reentry vehicle (MIRV) is an exoatmospheric ballistic missile payload containing several warheads, each capable of being aimed to hit a different target.
The warhead was initially manufactured from 1978 to 1987 and designed by Los Alamos National Laboratory.It was initially fitted to the Trident I SLBM system, but after the Rocky Flats plant where its successor the W88 was being made was shut down in 1989 after a production run of only 400 warheads, it was decided to transfer W76 warheads to Trident II.
