The reports on the left address the use of the Sono-buoy’s that were deployed against the unsuspecting Japanese submarine I-52.

 

The use of all the advanced technology at the time made the difference in winning the war against submarines.

 

The TPM Avenger piloted by Jesse Taylor was equipped with radar, an acoustic torpedo, and sono-buoys, all new technology.

 

The sono-buoys allowed the ASW aircraft to track submarines and thereby allowing for additional attacks, like the one made by Lt. Bill “Flash” Gordon in his attack on I-52.
