The Trident II Strategic Weapons System is an improved SLBM with greater accuracy, payload, and range than the earlier Trident C-4. It is a key element of the U.S. strategic nuclear triad and strengthens U.S. strategic deterrence. The Trident II is considered to be a durable sea-based system capable of engaging many targets.
It is accurate enough to be a first strike, counterforce, or second strike weapon. All three stages of the Trident II are made of graphite epoxy, making the missile much lighter. The Trident II was the original missile on the British Vanguard-class and American Ohio-class SSBNs from Tennessee on.
Trident of Poseidon. A trident (/ ˈ t r aɪ d ɛ n t /), (/ ˈ t r aɪ d ɪ n t /) is a three-pronged spear.It is used for spear fishing and historically as a polearm.As compared to an ordinary spear, the three tines increase the chance that a fish will be struck and decrease the chance that a fish will be able to dislodge itself if struck badly.
First deployed in 1979, the Trident I replaced the Poseidon missile. It was retired in 2005, having been replaced by the Trident II. [2] The missile was a three-stage, solid-fuelled system, capable of carrying up to eight W76 warheads in the Mark 4 RB. The first eight Ohio-class submarines were armed with Trident I
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.
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 UK Trident programme was announced in July 1980 and patrols began in December 1994. Trident replaced the submarine-based Polaris system, in operation from 1968 until 1996. Trident is the only nuclear weapon system operated by the UK since the decommissioning of tactical WE.177 free-fall bombs in 1998.
The trident also appears multiple times in popular culture: Poseidon's trident is owned by King Triton (Poseidon's son) in Disney's 1989 animated film The Little Mermaid and its sequels and spinoffs. Poseidon's Trident is a magical artifact with destructive powers in Michael Livingston's 2015 historical fantasy novel The Shards of Heaven. [17] [18]
