SKYWALKER, MUSIC - WAR DEEP BASS TONE

This is a Skywalker Sound sound effect. It was created by Gary Rydstrom, and it debuted in Saving Private Ryan (1998). It was made by Rydstrom having ocean sounds being played on speaker, and recording it with a microphone that was inside a long tube, and moving it around to give it a sort of "swirling" effect.
