The U.S. case is tied to nuclear carriers: a nuclear cruiser can keep pace during a fast transit when conventionally powered escorts may lag behind. USS Long Beach, USS Bainbridge, and USS Enterprise illustrate a fast nuclear task group with unusually low propulsion-fuel demands. One interpretation of the Soviet Kirov class treats the large ships as mobile command, anti-air, and anti-submarine platforms able to apply pressure far from home. Their enormous size also makes them conspicuous declarations of Soviet presence intended to intimidate. Reactors do not eliminate the need for food, ammunition, or aviation fuel, and slower supply ships may have to catch up after the nuclear group races ahead. The operational benefit is a lighter propulsion-fuel burden and faster movement between theatres while replenishment remains necessary.

Nuclear cruisers and fast task groups
Nuclear surface ships made the most sense as high-speed escorts and command vessels whose endurance reduced the logistical burden of moving a carrier task group between theatres.
