The Trident II (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. The D5 missile features advanced guidance systems and multiple independently targetable reentry vehicles (MIRVs), enabling it to deliver several warheads to different targets. First deployed in 1990, the Trident II has undergone several upgrades to enhance its accuracy and reliability, ensuring it remains a vital part of national defense.
