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).

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 concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads , even if not strictly being limited to ...

A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets.

2019年5月15日 · The Trident II D5 SLBM is a three-stage, solid-fuel, inertially-guided missile with a range of 4,000 nautical miles capable of carrying multiple W76-Mk4/Mk4A or W88-Mk5 reentry bodies. The...

2024年4月23日 · On September 17, the U.S. Navy launched two unarmed Trident II D5 Life Extended (LE) submarine-launched ballistic missiles (SLBM) in a scheduled flight test in waters off Cape Canaveral, Florida. The missiles, launched from Ohio-class submarine USS Wyoming (SSBN-742), landed in the Atlantic Ocean within the U.S. Eastern Test Range instrumented ...

2017年8月28日 · Multiple Independently-targetable Reentry Vehicles (MIRVs) were originally developed in the early 1960s to permit a missile to deliver multiple nuclear warheads to different targets. In contrast to a traditional missile, which carries …

2007年1月9日 · The W76 is the warhead used with the Mk 4 reentry vehicle which arms Trident II (D-5) submarine launched ballistic missiles (SLBMs). Designed for use on MIRV (multiple independently targeted reentry vehicle) bus upper stage. Two stage thermonuclear warhead. RV CEP (circle error probability) is 1250 feet.

The United States deployed its first MIRVed ICBM -- the Minuteman III -- in 1970, and the first MIRVed SLBM -- the Poseidon -- in 1971. The USSR followed suit in 1975 (ICBM) and 1978 (SLBM), respectively. MIRV technology was developed first in the United States.

The MIRV is one of a number of nuclear weapons that can be transported by an intercontinental ballistic missile (ICBM) or a submarine-launched ballistic missile (SLBM). The MIRV is distinct from the multiple reentry vehicle (MRV), which deploys multiple warheads against a single target.
