Full Specifications

Trident II D5 Submarine-Launched Ballistic Missile

The Trident II D5 is a cornerstone of the United States’ sea-based nuclear deterrent, designed for launch from ballistic missile submarines. It provides survivable, second-strike capability, ensuring strategic stability in high-threat environments. Known for its precision and reliability, the missile supports Multiple Independently Targetable Reentry Vehicles (MIRVs), allowing a single launch to engage multiple targets across vast distances.

Manufacturer

Developed and produced by Lockheed Martin Space, the Trident II D5 entered service with the U.S. Navy in 1990. It is deployed aboard Ohio-class and newer Columbia-class submarines. The system has undergone continuous upgrades under life-extension programs to maintain operational effectiveness through the coming decades.

Speed and Range

The Trident II D5 is an intercontinental ballistic missile with a range exceeding 7,400 km, capable of reaching targets across continents. It travels at hypersonic speeds, estimated above Mach 20 during its midcourse phase. Its advanced inertial navigation system, enhanced with stellar guidance updates, ensures high accuracy with a circular error probable measured in tens of meters.

Cost/Price

The estimated unit cost of a Trident II D5 missile is approximately $30 to $40 million, depending on configuration and upgrade packages. Lifecycle and modernization costs significantly increase total program expenditure, reflecting its strategic importance.
