Spruance could be counted on to take terrible risks if the situation demanded it (recollect the very early launch of the air strikes at Midway and the real likelihood of the loss of the only American aircraft carriers left. Remember only Enterprise survived).
The amazing thing was the number of carriers we had by 1945.
If we count the escort carriers, American industry launched the amazing total of 168 aircraft carriers before the end of 1945. :-)
Well, they were needed so Harry Calahan could jump ship to ship on a motorcycle.
