Northrop Grumman
Northrop Grumman has successfully manufactured two thousand solid rocket motors for the U.S. Navy’s Trident II D5 Submarine Launched Ballistic Missile (SLBM) system with the completion of first-stage A1000 and second-stage B1000 motors.
Northrop Grumman has manufactured:
- More than 800 first-stage tactical motors
- More than 800 second-stage tactical motors
- More than 370 third-stage tactical motors since assuming the scope of work in 1996
- And successfully cast over 86 million pounds of propellant for D5 motors
The system is provided to the U.S. Navy by prime contractor Lockheed Martin, which develops and produces the missile and support equipment. It has completed 190 successful flight tests since deployment with no motor failures. The Trident II D5 missile will continue to serve as the seaborne leg of the U.S. Nuclear Triad for decades to come.
