UGM-133A Trident II SLBM

UGM-133A Trident II, or Trident D5, is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space Systems in Sunnyvale, California, and deployed with the American and British navies.

The missile has a maximum operational range of over 7,500 miles (12,000 km) and a CEP of 90 meters (the exact values are classified). The missile’s MK 6 Astro-inertial guidance navigation system is also able to receive GPS (Global Positioning System) updates.

The missiles deployed on U.S. submarines can be equipped with a Mark 5 MIRV warhead that can carry up to 8 W88 (475 kt) warheads, or a Mark 4 MIRV that can also carry 14 W76 (100 kt) warheads.

Trident II missiles are carried by 14 U.S. Navy Ohio-class and four UK Royal Navy Vanguard-class ballistic missile submarines (SSBNs), with 24 missiles on each Ohio class and 16 missiles on each Vanguard class.

The D5 is the sixth in a series of missile generations deployed since the sea-based deterrent program began 60 years ago. The Trident D5LE (life-extension) version will remain in service until 2042.
