Trident II

Trident II is another common name for the UGM-133A Trident II D5 submarine-launched ballistic missile. This page should intentionally point readers toward the D5 identity while still providing standalone context, because many users search for the missile by the simpler Trident II name. It represents the latest operational generation of the U.S. Fleet Ballistic Missile family.

The missile is a three-stage solid-fuel strategic SLBM launched from submerged ballistic-missile submarines. Its guidance, range, and reentry-body compatibility give it the accuracy and flexibility expected of a modern strategic deterrent system. To avoid duplicate thin content, this entry emphasizes naming and family context while the Trident 2D5 page can carry more model-specific detail.

Trident II supports the sea-based leg of the nuclear triad by arming ballistic-missile submarines that are difficult to locate and target. Its operational value is deterrence stability: a survivable force can respond even after a first strike. The page should make clear that this is a nuclear strategic system, not a conventional or land-launched missile.
