The Trident D5 or UGM-133A Trident II is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space Systems in Sunnyvale, California, and deployed with the American and British navies. It was first deployed in March 1990. A total of 14 US Navy submarines are armed with Trident II ballistic missiles, each carrying 24 missiles. The Trident missile has a range from 6,400 to 11,250 km. The dimensions of the Trident II missile are 1,360 cm long with a diameter of 210 cm, and the weight is 59,000 kg. The Trident II missile is deployed aboard Ohio-class submarines, each capable of carrying 24 missiles. Under the provisions of the Polaris Sales Agreement, it is also carried aboard the United Kingdom's Vanguard-class submarines. Work will take place in Utah, California, Colorado, Florida and Virginia. Estimated completion will be in September 2024.
