The David Taylor class was a departure in design from traditional support ships.
Massing around 3 million tons, they were only about twenty percent bigger than Nike-class battlecruisers. They were designed as "fast combat support vessels", combining substantial repair capability and a modest capacity to carry ammunition/stores, while being fast enough to stay with a detached force of battlecruisers. They also contained armaments heavier than most light cruisers and eight launch bays for LACs. (HH15)
