The Trident D5 is a submarine-launched ballistic missile (SLBM) developed by the United States. It is designed to carry nuclear warheads and is primarily deployed on Ohio-class submarines. The missile has a range of over 7,000 miles and can deliver multiple warheads to different targets, enhancing its effectiveness as a strategic deterrent. First introduced in the late 1980s, the Trident D5 has undergone several upgrades to improve its accuracy and reliability. It is a key component of the U.S. nuclear triad, which includes land-based intercontinental ballistic missiles (ICBMs) and strategic bombers, ensuring a robust defense capability.
