While the first few small carriers took five or six months to convert, by the time that the first Block Island was constructed the construction time was cut to less than three months. At that time it was taking as long as two years to construct the larger carriers. The best understanding of this undertaking is that eight small carriers carrying 20 planes each could be constructed in the same period of time it took to construct a larger carrier. The larger carriers could only handle as many as 90 aircraft with a total construction cost of around $120 million. Smaller carriers were built at a cost of $11 million each and carried 20 aircraft. The large carriers moved around at 30 knots compared with about 20 knots for small carriers. The smaller carriers became “the plan of the day” in the Pacific. While more escort and service ships were required to service the eight small carriers, the loss of a large carrier put 90 aircraft out of action and involved over 3000 crew members. The loss of a small carrier only put 20 aircraft out of service and involved around 900 crew members. However, when the large carrier was lost there was not another carrier available to save its aircraft. If a small carrier was lost, the aircraft then could land on and work from one of the other small carriers. When it came time to construct the second Block Island the construction time was cut to 79 days. Admiral Kincade advised congress that he could launch and retrieve 160 aircraft in half the time it would take the larger carriers to land and launch 90 planes.
