The Trident II ballistic missile, also known as the Trident D5, is a submarine-launched ballistic missile (SLBM) developed by the United States. It is designed to carry nuclear warheads and has a range of over 7,000 miles, allowing it to strike targets across the globe. The missile is deployed on Ohio-class submarines, providing a key component of the U.S. nuclear deterrent strategy. First introduced in the late 1980s, the Trident II has undergone several upgrades to enhance its accuracy and reliability. It is capable of carrying multiple independently targetable reentry vehicles (MIRVs), which allows a single missile to hit multiple targets. The Trident II remains a vital part of the U.S. military's strategic arsenal.
