Trident II D5 Missile: Keeping Up with Changing Times
June 26/17: Electric Boat has been awarded a $203 million contract modification to conduct work for the joint US Navy-UK Common Missile Compartment program. The work order calls for the design, testing, and delivery of missile tubes for the Trident II D5 submarine launched ballistic missile used by the US and British navies and will be installed on both navies’ replacement ballistic missile submarine classes, the Colombia and Dreadnought. Work will take place at Groton, Conn., Newport News, Va., and several other sites with completion scheduled for October 2017.
Nuclear tipped missiles were first deployed on board US submarines at the height of the Cold War in the 1960s, to deter a Soviet first strike. The deterrence theorists argued that, unlike their land-based cousins, submarine-based nuclear weapons couldn’t be taken out by a surprise first strike, because the submarines were nearly impossible to locate and target. Which meant that Soviet leaders could not hope to destroy all of America’s nuclear weapons before they could be launched against Soviet territory. SLBM/FBM (Submarine Launched Ballistic Missile/ Fleet Ballistic Missile) offered shorter ranges and less accuracy than their land-based ICBM (Inter-Continental Ballistic Missile) counterparts, but the advent of Trident C4 missiles began extending those ranges, and offering other improvements. The C4s were succeeded by larger Trident II D5 missiles, which added precision accuracy and more payload.
The year that the Trident II D5 ballistic missile was first deployed, 1990, saw the beginning of the end of the missile’s primary mission. Even as the Soviet Union began to implode, the D5’s performance improvements were making the Trident submarine force the new backbone of the USA’s nuclear deterrent – and of Britain’s as well. To ensure that this capability was maintained at peak readiness and safety, the US Navy undertook a program in 2002 to replace aging components of the Trident II D5 missile called the D5 Life Extension (LE) Program. This article covers D5 LE, as well as support and production contracts associated with the American and British Trident missile fleets.
