Your quote is not from Y'Blood's book, but from a promotional teaser (well, two of them, actually) for that book, written by the staff at amazon.com and included on the web page offering the book for sale. Here is a quote from a review posted on the same page. (Emphasis added.)
"
This is a history of the US escort carrier groups in the Battle of the Atlantic. These groups were used in a variety of roles, but the main focus of this book is on their use as hunter-killer teams fighting the U-boats.
While
the battle against the U-boats had turned a corner by the time these carriers were active, the carriers were excellent in fighting the U-boats offensively. How they did so is well told by Y'blood, although
some of these insights need to be uncovered by a discerning reader. Their success highlights how
several elements had to come together to defeat the U-boats: technological advances by those ashore; intelligence (Enigma, Huff-Duff); tactics; execution by those at the sharp end."
If I may add a further quote from the Amazon site:
"About the Author: William T. Y'Blood, a former USAF B-47 pilot and historian for the Office of Air Force History in Washington, DC...."
Having worked closely with the USAF for many years, I think it is likely that Y'Blood shared the view held by many Air Force officers that air power always dominates the battlespace.
