Why Nuclear Weapon Convoys?
A Deadly Cargo
A nuclear weapon convoy is a cluster of vehicles travelling by road in convoy formation. It can be:
The Trident warheads are carried in large crates inside the green trucks. They are fully assembled and complete. The core of the warhead is a ball of plutonium and uranium. This is surrounded by specially developed conventional high explosives which would be ignited to create the critical mass necessary for a nuclear detonation when launched and targeted.
As well as the nuclear warhead convoys there are other nuclear transports on the roads - Special Nuclear Materials (SNM) convoys which have blue carriers rather than green. They have a smaller escort, travel faster at 60mph and do not use north eastern routes.
