Each Trident I and Trident II explodes with the force of 100 kilotons. The Trident II also has more advanced guidance systems, which (at least theoretically) allow the accuracy needed to destroy highly blast-resistant targets, such as hardened Soviet missile silos. Each Trident I and Trident II missile holds eight W-76 warheads. There are eight Ohio-class submarines and 14 Trident submarines, each of which holds 24 Trident I or Trident II missiles.
