The Trident missile is a submarine-launched ballistic missile (SLBM) equipped with multiple independently targetable reentry vehicles (MIRV). Originally developed by Lockheed Missiles and Space Corporation , the missile is armed with thermonuclear warheads and is launched from nuclear-powered ballistic missile submarines (SSBNs).
It is unclear if the W93 will replace the W76-1, the W88 or both warheads. [45] In UK usage Trident II missiles are equipped with a warhead called Holbrook [46] and have a maximum yield of 100 kt. [47] The UK government insists the warhead is a British design, but analysts believe that it is largely based on the US W76 design.
In British service, Trident II missiles are fitted with a thermonuclear warhead called Holbrook. [100] The warhead has a choice of two warhead yields [ 101 ] the highest of which is thought to be 100 kilotons of TNT (420 TJ), with a lower yield in the range of 0.3 to 10 kilotons of TNT (1.3 to 41.8 TJ).

A British nuclear missile test launch failed at a test site off the coast of Florida, marking the second time in eight years that the country’s Trident 2 ballistic missiles have malfunctioned ...
The introduction of MIRV led to a major change in the strategic balance. Previously, with one warhead per missile, it was conceivable that one could build a defense that used missiles to attack individual warheads. Any increase in missile fleet by the enemy could be countered by a similar increase in interceptors. With MIRV, a single new enemy ...

LONDON (Reuters) -Britain's Trident nuclear-deterrent system misfired during a test last month, sending a missile crashing into the ocean off the Florida coast near the submarine that launched it ...
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.
