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...

トライデント（Trident）は、複数個別誘導再突入体（MIRV）付き潜水艦発射弾道ミサイル（SLBM）。 アメリカ海軍では艦隊弾道ミサイル（FBM: Fleet Balistic Missile）と呼ばれ、 核弾頭 を装備し、原子力推進 弾道ミサイル潜水艦 から発射される。

2025年3月14日 · The Trident II (D-5) Missile, also known as the UGM-133A, is a U.S. inter-continental-range, submarine-launched, solid-propellant, MIRV-capable ballistic missile. It represents the sixth and latest generation of the U.S. Navy’s Fleet Ballistic Missile (FBM) Systems marking a significant development in the United States’ missile technology.

2024年4月23日 · The UGM-133 Trident II D5 is the U.S. Navy’s latest generation submarine-launched ballistic missile (SLBM). It improved upon earlier SLBMs including the Polaris, Poseidon, and Trident I C4. These programs, categorized as US Fleet Ballistic Missile technologies, began in the mid-1950s.

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.

Today, the United States, the United Kingdom, and France use MIRV technology on SLBMs. China has MIRVed ICBMs, while Russia deploys both MIRVed ICBMs and SLBMs. The use of MIRVs on submarines is considered less destabilizing than on land-based missiles because the difficulty of finding nuclear submarines makes strikes against them unlikely.

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.
