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 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).
The W76-0 had a design yield of 100 kt while its replacement the W76-1 has a yield of 90 kt. The W76-2 has an estimated yield of 5 to 7 kt. [16] The W76-0 was fitted inside a Mk4 reentry vehicle (reentry body in US Navy parlance) while the W76-1 and -2 are fitted inside the new Mk4A reentry vehicle. Reentry vehicle and warhead weight is ...
The value of an egg-shaped primary lies apparently in the fact that a MIRV warhead is limited by the diameter of the primary—if an egg-shaped primary can be made to work properly, then the MIRV warhead can be made considerably smaller yet still deliver a high-yield explosion—a W88 warhead manages to yield up to 475 kt with a reentry vehicle ...

Test launch of a Trident II missile. Trident II D-5 is a submarine-launched ballistic missile built by Lockheed Martin Space Systems in Sunnyvale, California, and deployed by the US Navy and the Royal Navy. [122] The British government contributed five per cent of its research and development costs under the modified Polaris Sales Agreement.
Exploded diagram of the Mk21 reentry vehicle for the W87 [clarification needed]. The W87 is an American thermonuclear missile warhead formerly deployed on the LGM-118A Peacekeeper ("MX") ICBM. 50 MX missiles were built, each carrying up to 10 W87 warheads in multiple independently targetable reentry vehicles (MIRV), and were deployed from 1986 to 2005.
