The Trident II (D5) is a submarine-launched ballistic missile (SLBM) developed by Lockheed Martin for the United States Navy. It is designed to carry multiple nuclear warheads and has a range of over 7,000 miles, making it a key component of the U.S. nuclear deterrent strategy. The missile is deployed on Ohio-class submarines, which provide stealth and mobility. First introduced in the late 1980s, the Trident II has undergone several upgrades to enhance its accuracy and reliability. It is capable of carrying up to eight W76 or W88 warheads, allowing for flexible targeting options. The missile's advanced guidance system ensures precision in striking designated targets.
