Aggressors: Patrol Aircraft Vs. Submarineries

This is volume 4 in a series of 4 books about a particular aspect of the wider technology battle that took place during World War II. I bought this book to help complete my Aggessors collection. It has lots of valuable information and gives a nice history as the technology and tactics progressed during the war. It covers both the Allied and Axis perspectives. It has lots of illustrations and cutaways. Recommended!
