Actually yea it can because the more re-entry vehicles you use the smaller the blast radius of each will be. the fireball radius of the largest current US-made warhead is only .71km at 455kt on the Trident missile (W-88). It carries 12 re-entry vehicles which could blanket approximately a 3sq km zone. An aircraft carrier can move at approximately 1km per minute. so you have approximately 90 seconds to launch and hit the target with one of the US's best weapons.
