Description:
The C-4 Trident is a submarine-launched, intercontinental ballistic missile designed to be an integral part of the American nuclear deterrent aboard Ohio-class submarines. It was first deployed in 1979 and 8 Ohio-class submarines were armed with this missile.
The C-4 Trident, also known as UGM-99A, is a three-stage solid fuel ballistic missile armed with up to 10 nuclear warheads called Multiple Independently targetable Re-entry Vehicle (MIRV). Each MIRV can be assigned to different targets within the impact area covered by the ballistic missile that usually is measured in hundreds of kilometers.
The Trident I was installed in the first 8 Ohio-class submarines commissioned by the US Navy. Four of them will be converted to the SSGN role and the remaining four submarines will be re-armed with the more capable Trident II replacing the Trident I missile.
In late October 2005 the US Navy decommissioned the last C4 Trident I missile offloading from the USS Alabama (SSBN 731) nuclear-powered ballistic submarine at the Explosive Handling Wharf on Naval Base Kitsap. The USS Alabama was scheduled to be refitted with D5 Trident II ballistic missiles in early 2006.
