Lockheed Martin Space won a $559 modification contract for Trident II D5 Submarine-Launched Ballistic Missile (SLBM).
The contract includes Trident II D5 missile production and deployed system support, US Department of Defense said in a statement Wednesday.
SLBMs have evolved through Polaris (A2), Polaris (A3), Poseidon (C3) Trident I (C4) and today’s force of Trident II D5.
The Trident II D5 is a three-stage, solid-propellant, inertial-guided ballistic missile. It can carry multiple independently targeted re-entry bodies for a maximum range of over 7,360km.
Work is expected to be completed September 30, 2023.
