The Trident Missile is a type of submarine-launched ballistic missile (SLBM) developed by the United States. It is designed to carry nuclear warheads and is primarily used by the U.S. Navy's fleet of nuclear-powered submarines. The missile has a range of over 4,000 miles, allowing it to strike targets far from its launch point. The Trident system includes the Trident I (C4) and Trident II (D5) variants, with the latter being the more advanced version. These missiles are part of the U.S. strategic nuclear deterrent, ensuring that the country can respond to threats effectively. The Trident program is also used by the United Kingdom, which operates its own version of the missile.
